          21A.01.020  Zoning code adopted.  Under the provisions of Article XI, Section 11 of the Washington State Constitution and Article 2, Section 220.20 of the King County Charter, the zoning code attached to Ordinance 10870, which is referred to hereinafter as the 1993 Zoning Code, is adopted and declared to be the zoning code for King County until amended, repealed or superseded, subject to the provisions of K.C.C. 21A.01.030.  This code also is hereby enacted to be consistent with and implement the comprehensive plan in accordance with RCW 36.70A. This code shall be compiled in Title 21A.  (Ord. 11621 § 1 (part), 1994:  Ord. 10870 § 2, 1993).


          21A.01.025  Notification to Tribes.  The county recognizes that many actions undertaken pursuant to Title 21A, as amended, may impact treaty fishing rights of federally-recognized tribes.  In order to honor and prevent interference with these treaty fishing rights and to provide for water quality and habitat preservation, the county shall provide notice to any federally-recognized tribes whose treaty fishing rights would be affected by an action undertaken pursuant to this title, including but not limited to:  development of wetlands, stream and river banks, lakeshore habitat of water bodies, or development directly or indirectly affecting anadromous bearing water bodies, including the promulgation of plans, rules, regulations or ordinances implementing the provisions of this title, whether or not review of such actions is required under the State Environmental Policy Act (SEPA) RCW 43.21C.  (Ord. 11621 § 1 (part), 1994).


          21A.01.030  Application of the 1993 Zoning Code.

          A.  Except as provided in subsection C below, the 1993 Zoning Code shall apply to a specific property when, after the June 28, 1993, the zoning map with respect to such property is amended pursuant to:

            1.  an individual quasi-judicial zone reclassification;

            2.  countywide zoning conversion process set out in K.C.C. 21A.01.070; or

            3.  community planning area zoning proposals accompanying plan updates or amendment studies.

          B.  Any reclassification requests or proposals for application of area or countywide zoning initiated after June 28, 1993, shall use the new zone classifications adopted in the 1993 Zoning Code.

          C.  The provisions of King County Code Chapter 21A.24, together with the relevant provisions of Chapters 21A.06 and 21A.12, shall apply to all properties as of January 9, 1994.  (Ord. 11621 § 2, 1994:  10870 § 3, 1993).


          21A.01.040  Transition to new code.

          A.  Complete applications for conditional use permits, planned unit developments, binding site plans, right-of-way use permits, commercial site development permits, variances, unclassified use permits, or public agency and utility exceptions which were pending at the time Title 21A took effect shall continue to be processed under those applicable zoning regulations governing review prior to implementation of Title 21A; except when a conditional use permit application has been submitted for a use that under Title 21A no longer requires a conditional use permit, that conditional use permit shall not be a requirement for the vested development proposal.  Notwithstanding any contrary provisions in this title, where approved, these permits shall continue to establish allowable uses on the property until permit expiration.  A variance to Title 21 standards which has been approved and has not expired shall be deemed to also vary like standards set forth in Title 21A relating to the same subject matter and development proposal.  Planned unit development applications pending on October 1, 1994 shall be deemed to have vested at the time a complete application was filed.  Nothing in this subsection is intended to restrict otherwise applicable vested applicant rights.

          B.  Except for the requirements of K.C.C. 21A.43, any lot created by subdivision or short subdivision for which a complete subdivision or short subdivision application was submitted prior to February 2, 1995, may be developed pursuant to the standards of Resolution 25789, as amended (former K.C.C. Title 21), including any applicable p-suffix conditions in adopted community plans and area zoning in effect on February 1, 1995 for a period of six years from the date of recording of the applicable final plat or short plat.  (Ord. 12824 § 19, 1997:  Ord. 11765 § 1, 1995:  Ord. 11621 § 3, 1994:  10870 § 4, 1993).


          21A.01.045  Relationship to certain adopted 1994 development regulations.

          A.  The King County Council makes the following findings of fact:

            1.  On December 19, 1994, the King County Council adopted Ordinance 11618, 11619, and 11620 amending Title 16 of the King County Code.  The effective date of Ordinance 11618, 11619, and 11620 is January 9, 1995.

            2.  In drafting Ordinance 11618, 11619, and 11620, the references to the King County Zoning Code were amended to cite K.C.C. Title 21A, the new zoning code, and at the same time repeal references to K.C.C. Title 21, the old zoning code.  This was done in anticipation that Proposed Ordinance 94-737, which adopts new zoning to implement the 1994 Comprehensive Plan and Title 21A, adopted would be on December 19, 1994 concurrent with Ordinance 11618, 11619, and 11620.  Thus, K.C.C. Title 21A would become effective on the same date as Ordinance 11618, 11619, and 11620 [January 9, 1995].

            3.  However, on December 19, 1994 the King County Council deferred action on Proposed Ordinance 94-737 until January 3, 1995.  On January 3, 1995 the action was again deferred to January 9, 1995.  As a result of deferring action on Proposed Ordinance 94-737, K.C.C. 21A will not go into effect until some time after January 9, 1995.

            4.  The problem created by the actions described above is that Ordinance 11618, 11619, and 11620 will go into effect with references to zoning code requirements (K.C.C. Title 21A) that will not be in effect until the adoption and effective date [February 2, 1995] of Proposed Ordinance 94-737.  Additionally, the references to the existing zoning code (K.C.C. Title 21) are repealed in Ordinance 11618, 11619, and 11620.  As a result, development applications filed between January 9, 1995, and February 2, 1995, may vest to land use controls that will not include either existing Title 21 or the new Title 21A regulations.  Such development may not provide protection for, and be harmful to, the public health, safety and welfare which Title 21 and 21A were adopted to address.

          B.  Ordinance 11618, 11619, and 11620 shall not take effect, or if in effect shall no longer be in effect, until King County adopts zoning to implement the 1994 King county Comprehensive Plan and to convert zoning to Title 21A (Proposed Ordinance 94-737) and such zoning becomes effective.  Prior to January 9, 1995, provisions of law in effect prior to the adoption of January 9, 1995, shall remain in effect until Ordinance 11618, 11619, and 11620 is in effect under the provisions of this section.  (Ord. 11652 § 1-2, 1995).


          21A.01.050  Tree retention and landscaping effective date.  Chapter 21A.16 (Tree Retention and Landscaping) shall be effective as part of the 1993 Zoning Code only if at the time of the adoption of the first area zoning map conversion a new landscaping chapter has not been adopted, in which case chapter 21A.16 will apply in that area until a revised chapter is adopted.  (Ord. 10870 § 9, 1993).


          21A.01.070  Area zoning conversion guidelines.

          A.  The council directs the department to prepare proposed new zoning maps applying the 1993 King County Zoning Code and transmit within ten months of June 28, 1993, for council review and adoption.

          B.  The department shall use the table in subsection C. of this section and the guidelines of this section in preparing an ordinance or ordinances to convert each area zoning document to the 1993 Zoning Code, with modifications appropriate to be consistent with the Comprehensive Plan land use map and policies, so as to implement the Comprehensive Plan and convert old outright and potential zoning classifications to new ones in a consistent manner.  This section also shall apply to conversion of the resource lands area zoning adopted pursuant to K.C.C. 20.12.390.

          C.  Conversion table.  The following conversion table and criteria contained therein shall be used by the department in converting the zoning maps adopted pursuant to Resolution 25789 to the 1993 Zoning Code:







In Forest Production or Rural Areas


F or RA

Use zone most consistent with the Comprehensive Plan

A, A-10



A-35 or A-60

NB or RB






M-L, M-P, M-H

CB or RB




For all business zones, use zone most consistent with the Comprehensive Plan designation and actual scale of business area

          D.  Unclassified Use Permit Mining Operations.  In addition to the conversions set out in the table in subsection C. of this section, all sites legally operating pursuant to an unclassified use permit for mining operations shall be zoned M (Mineral).

          E.  Resolution of map conflicts.  In cases of ambiguity or conflict between a community or Comprehensive Plan land use designation and the zoning classification applied under the old code, the department shall use the following guidelines and procedures in recommending new zones:

            1.  As a general rule, the outright or potential zoning classification applied shall be that which is consistent with the 1994 King County Comprehensive Plan; adopted community plans, where they do not conflict, may be used to provide additional guidance;

            2.  If the application of the guidelines in this subsection leads the department to propose applying an outright or potential zoning classification from the 1993 Zoning Code that is not functionally equivalent to a classification from the old code as defined in the table in subsection C. of this section, the department shall notify the owner of the property proposed for reclassification no later than the council introduction date of the ordinance amending said property, and the property owner may request a change in the area zoning in a manner consistent with the procedures used for council review of a community plan and area zoning.

          F.  Area-wide P-suffix development conditions.  The department shall review all area-wide P-suffix conditions applied through zoning adopted pursuant to Resolution 25789, and recommend legislation removing all such conditions which conflict with the Comprehensive Plan or have been replaced adequately by standards adopted in the 1993 zoning code.  If P-suffix conditions implement policies in the Comprehensive Plan, then regulations shall be developed by the end of 1995 and the P-suffix conditions shall be removed. Any P-suffix conditions which implement policies in community plans which are not in conflict with the Comprehensive Plan but are not adequately addressed by this code shall be carried forward intact until they are evaluated for replacement by general code revisions in 1995.

          G.  Site-specific development conditions.  Approval conditions for previous zone reclassifications, planned unit developments, unclassified permits, and P-suffix conditions applied to individual properties in land use actions pursuant to Resolution 25789, should be recommended for retention wherever they address conditions unique to a particular property and not addressed by the standards in the Zoning Code.

          H.  For area zoning documents being converted to the 1993 Zoning Code without amendments to their respective community plan maps and policies, only requests for zone changes which meet one of the following criteria shall be considered during either the department or council review process:

            1.  As provided in subsection E. of this section;

            2.  When an applicant can demonstrate that the department's proposal incorrectly implements an adopted Comprehensive Plan map designation or policy in converting existing zoning to a new zoning classification; or

            3.  The site is the subject of an application for a Master Planned Development or Urban Planned Development, and conversion to the 1993 Zoning Code is requested as part of such application.  Rezoning of such sites during the conversion, area zoning otherwise shall be to Urban Reserve with the urban planned development overlay district as provided in K.C.C. chapter 21A.38.

          I.  Requests which do not meet one of the criteria of subsection H. of this section shall be treated as quasi-judicial reclassification requests which must be formally applied for according to the process provided for such requests and shall be subject to the criteria in K.C.C. 20.22.150.

          J.  Requests for quasi-judicial reclassification that are consistent with the conversion table illustrated in subsection C. of this section and requests for quasi-judicial reclassification to the M zone, shall not be subject to the criteria in K.C.C. 20.22.150.

          K.  Bear Creek MPD's.  The following transition provisions shall apply to the Master Plan Development applications in the Bear Creek Community Plan (BCCP).

            1.  An applicant may either continue to utilize the procedural provisions of the BCCP or may utilize the procedural provisions of K.C.C. chapter 21A.39.

            2.  If an applicant utilizes the procedural provisions of K.C.C. 21A.39, the Pre-Development Applications previously submitted for the Blakely Ridge MPD and the Northridge MPD are deemed the equivalent of and accepted as complete applications for "UPD Permits" under Chapter 21A.39 of the 1993 zoning code.

            3.  The substantive provisions of the BCCP Area Zoning MPD P-Suffix conditions and conditions precedent to rezoning set forth in Section 1C of the BCCP Area Zoning (page 140) shall remain in effect for purposes of considering the UPD applications, under either the BCCP or K.C.C. chapter 21A.39.

            4.  The applicants may elect either one base zone pursuant to K.C.C. 21A.39, or multiple zones pursuant to the Bear Creek Community Plan, applying the equivalent zone and potential zoning classifications of the 1993 zoning code.

            5.  The Novelty Hill Master Plan sites and urban designation adopted and delineated in the Bear Creek Community Plan and Bear Creek Area zoning shall be considered "UPD Special District Overlays" and "UPD boundary delineations" for purposes of applying K.C.C. 21A.38.020, 21A.38.070B.1. and 2. and K.C.C. 21A.39.020.  (Ord. 19146 § 15, 2020:  Ord. 18230 § 124, 2016:  Ord. 11621 § 5, 1994:  Ord. 11157 § 1, 1993:  Ord. 10870 § 5, 1993).


          21A.01.090  Drawings.  The department is hereby authorized after June 7, 1993, to incorporate drawings as necessary for the purpose of illustrating concepts and regulatory standards contained in this title, provided that the adopted provisions of the code shall control over such drawings.  (Ord. 10870 § 7, 1993).


          21A.01.100  Periodic review.  The department shall submit an annual written report to the council detailing issues relating to the implementation of the 1993 King County Zoning Code and recommending amendments to address those issues.  (Ord. 10870 § 8, 1993).

          21A.02.010  Title.  This title shall be known as the King County Zoning Code.  (Ord. 15051 § 1, 2004:  Ord. 10870 § 11, 1993).


          21A.02.020  Authority to adopt code.  The King County Zoning Code is adopted by King County ordinance, pursuant to Article XI, Section 11 of the Washington State Constitution; and Article 2, Section 220.20 of the King County Charter.  (Ord. 10870 § 12, 1993).


          21A.02.030  Purpose.  The general purposes of this title are:

          A.  To encourage land use decision making in accordance with the public interest and applicable laws of the State of Washington.

          B.  To protect the general public health, safety, and welfare;

          C.  To implement the King County Comprehensive Plan's policies and objectives through land use regulations;

          D.  To provide for the economic, social, and aesthetic advantages of orderly development through harmonious groupings of compatible and complementary land uses and the application of appropriate development standards;

          E.  To provide for adequate public facilities and services in conjunction with development; and

          F.  To promote general public safety by regulating development of lands containing physical hazards and to minimize the adverse environmental impacts of development.  (Ord. 10870 § 13, 1993).


          21A.02.040  Conformity with this title required.

          A.  No development, use or structure shall be established, substituted, expanded, constructed, altered, moved, maintained, or otherwise changed except in conformance with this title.

          B.  Creation of or changes to lot lines shall conform with the use provisions, dimensional and other standards, and procedures of this title and Title 19, Subdivisions.

          C.  All land uses and development authorized by this title shall comply with all other regulations and or requirements of this title as well as any other applicable local, state or federal law.  Where a difference exists between this title and other county regulations, the more restrictive requirements shall apply.

          D.  Where more than one part of this title applies to the same aspect of a proposed use or development, the more restrictive requirement shall apply.

          E.  Temporary uses or activities, conducted during an emergency event, or training exercises conducted at emergency sites, designated pursuant to an emergency management plan, shall not be subject to the provisions of this title.  (Ord. 16985 § 126, 2010:  Ord. 11621 § 8, 1994:  10870 § 14, 1993).


          21A.02.050  Minimum requirements.  In interpretation and application, the requirements set forth in this title shall be considered the minimum requirements necessary to accomplish the purposes of this title.  (Ord. 10870 § 15, 1993).


          21A.02.055  Covenant of retention of common ownership for lots considered as a site.

          If a development proposal depends on two or more lots to be considered as a site for purposes of complying with the provisions of this title or any other provision of the King County Code, the department may require the applicant to record a covenant to the benefit of the county that requires the retention of the lots under common ownership and control for the duration that the use is maintained on the site.  (Ord. 17191 § 18, 2011).


          21A.02.060  Interpretation: General.

          A.  In case of inconsistency or conflict, regulations, conditions or procedural requirements that are specific to an individual land use shall supersede regulations, conditions or procedural requirements of general application.

          B.  A land use includes the necessary structures to support the use unless specifically prohibited or the context clearly indicates otherwise.

          C.  In case of any ambiguity, difference of meaning, or implication between the text and any heading, caption, or illustration, the text and the permitted use tables in K.C.C. 21A.08 shall control.  All applicable requirements shall govern a use whether or not they are cross-referenced in a text section or land use table.

          D.  Unless the context clearly indicates otherwise, words in the present tense shall include past and future tense, and words in the singular shall include the plural, or vice versa.  Except for words and terms defined in this title, all words and terms used in this title shall have their customary meanings.  (Ord. 10870 § 16, 1993).


          21A.02.070  Interpretation: Standard industrial classification.

          A.  All references to the Standard Industrial Classification (SIC) are to the titles and descriptions found in the Standard Industrial Classification Manual, 1987 edition, prepared by United States Office of Management and Budget which is hereby adopted by reference.  The (SIC) is used, with modifications to suit the purposes of this title, to list and define land uses authorized to be located in the various zones consistent with the comprehensive plan land use map.

          B.  The SIC categorizes each land use under a general two-digit major group number, or under a more specific three- or four-digit industry group or industry number.  A use shown on a land use table with a two-digit number includes all uses listed in the SIC for that major group. A use shown with a three-digit or four-digit number includes only the uses listed in the SIC for that industry group or industry.

          C.  An asterisk (*) in the SIC number column of a land use table means that the SIC definition for the specific land use identified has been modified by this title.  The definition may include one or more SIC subclassification numbers, or may define the use without reference to the SIC. 

          D.  The Director shall determine whether a proposed land use not specifically listed in a land use table or specifically included within a SIC classification is allowed in a zone. The director's determination shall be based on whether or not permitting the proposed use in a particular zone is consistent with the purposes of this title and the zone's purpose as set forth in K.C.C. 21A.04, by considering the following factors:

            1.  The physical characteristics of the use and its supporting structures, including but not limited to scale, traffic and other impacts, and hours of operation;

            2.  Whether or not the use complements or is compatible with other uses permitted in the zone; and

            3.  The SIC classification, if any, assigned to the business or other entity that will carry on the primary activities of the proposed use. (Ord. 11621 § 7, 1994:  10870 § 17, 1993).


          21A.02.080  Interpretation:  Zoning maps.  Where uncertainties exist as to the location of any zone boundaries, the following rules of interpretation, listed in priority order, shall apply:

          A.  Where boundaries are indicated as paralleling the approximate centerline of the street right-of-way, the zone shall extend to each adjacent boundary of the right-of-way.  Non road-related uses by adjacent property owners, if allowed in the right-of-way, shall meet the same zoning requirements regulating the property owners lot;

          B.  Where boundaries are indicated as approximately following lot lines, the actual lot lines shall be considered the boundaries;

          C.  Where boundaries are indicated as following lines of ordinary high water, or government meander line, the lines shall be considered to be the actual boundaries.  If these lines should change the boundaries shall be considered to move with them; and

          D.  If none of the rules of interpretation described in subparagraphs A. through C. apply, then the zoning boundary shall be determined by map scaling.  (Ord. 10870 § 18, 1993).


          21A.02.090  Administration and review authority.

          A.  The hearing examiner in accordance with K.C.C. chapter 20.22 may hold public hearings and make decisions and recommendations on reclassifications, subdivisions and other development proposals, and appeals.

          B.  The director may grant, condition or deny applications for variances, conditional use permits, renewals of permits for mineral extraction and processing, alteration exceptions and other development proposals, unless an appeal is filed and a public hearing is required under K.C.C. chapter 20.20, in which case this authority shall be exercised by the hearing examiner.

          C.  The department shall have authority to grant, condition or deny commercial and residential building permits, grading and clearing permits, and temporary use permits in accordance with the procedures in K.C.C. chapter 21A.42.

          D.  Except for other agencies with authority to implement specific provisions of this title, the department shall have the sole authority to issue official interpretations and adopt public rules to implement this title, in accordance with K.C.C. chapter 2.98.  (Ord. 18230 § 125, 2016:  Ord. 15051 § 2, 2004:  Ord. 10870 § 19, 1993).


          21A.02.110  Classification of right-of-way.

          A.  Except when such areas are specifically classified on the zoning map as being classified in one of the zones provided in this title, land contained in rights-of-way for streets or alleys, or railroads shall be considered unclassified.

          B.  Within street or alley rights-of-way, uses shall be limited to street purposes as defined by law.

          C.  Within railroad rights-of-way, allowed uses shall be limited to tracks, signals or other operating devices, movement of rolling stock, utility lines and equipment, and freight-rail dependent uses.

          D.  Where such right-of-way is vacated, the vacated area shall have the zoning classification of the adjoining property with which it is first merged.  (Ord. 19146 § 16, 2020:  Ord. 10870 § 21, 1993).

          21A.04.020  Zoning classification purpose statement.  The purpose statements for each zoning classification set forth in the following sections shall be used to guide the application of the zoning classifications to all lands in unincorporated King County.  The purpose statements also shall guide interpretation and application of land use regulations within the zoning classifications, and any changes to the range of permitted uses within each zoning classification through amendments to this title.  (Ord. 19146 § 18, 2020:  Ord. 10870 § 23, 1993).


          21A.04.030  Agricultural zone.

          A.  The purpose of the agricultural zone (A) is to preserve and protect irreplaceable and limited supplies of farmland well suited to agricultural uses by their location, geological formation and chemical and organic composition and to encourage environmentally sound agricultural production.  These purposes are accomplished by:

            1.  Establishing residential density limits to retain lots sized for efficient farming;

            2.  Allowing for uses related to agricultural production and limiting nonagricultural uses to those compatible with farming, or requiring close proximity for the support of agriculture; and

            3.  Allowing for residential development primarily to house farm owners, on-site agricultural employees and their respective families.

          B.  Use of this zone is appropriate for lands within agricultural production districts designated by the Comprehensive Plan and for other farmlands deemed appropriate for long-term protection.  (Ord. 10870 § 24, 1993).


          21A.04.040  Forest zone.

          A.  The purpose of the forest zone (F) is to preserve the forest land base; to conserve and protect the long-term productivity of forest lands; and to restrict uses unrelated to or incompatible with forestry. These purposes are accomplished by:

            1.  Applying the F zone to large contiguous areas where a combination of site, soil and climatic characteristics make it possible to sustain timber growth and harvests over time;

            2.  Limiting residential, recreational, commercial and industrial uses to those uses that are compatible with forestry, to minimize the potential hazards of damage from fire, pollution and land use conflicts; and

            3.  Providing for compatible outdoor recreation uses and for conservation and protection of municipal watersheds and fish and wildlife habitats.

          B.  Use of this zone is appropriate for lands within forest production districts designated by the Comprehensive Plan.  (Ord. 10870 § 25, 1993).


          21A.04.050  Mineral zone.

          A.  The purpose of the mineral zone (M) is to provide for continued extraction and processing of mineral and soil resources in an environmentally responsible manner by:

            1.  Reserving known deposits of minerals and materials within areas as protection against premature development of the land for non-extractive purposes;

            2.  Providing neighboring properties with notice of prospective extracting and processing activities; and

            3.  Providing appropriate location and development standards for extraction and on-site processing to mitigate adverse impacts on the natural environment and on nearby properties.

          B.  Use of this zone is appropriate for known deposits of minerals and materials on sites that are of sufficient size to mitigate the impacts of operation and that are served or capable of being served at the time of development by adequate roads and other public services; and for sites containing mineral extracting and processing operations that were established in compliance with land use regulations in effect at the time the use was established.  (Ord. 10870 § 26, 1993).


          21A.04.060  Rural area zone.

          A. The purpose of the rural zone (RA) is to provide for an area-wide long-term rural character and to minimize land use conflicts with nearby agricultural or forest production districts or mineral extraction sites.  These purposes are accomplished by:

            1.  Limiting residential densities and permitted uses to those that are compatible with rural character and nearby resource production districts and sites and are able to be adequately supported by rural service levels;

            2.  Allowing small scale farming and forestry activities and tourism and recreation uses that can be supported by rural service levels and that are compatible with rural character;

            3.  Increasing required setbacks to minimize conflicts with adjacent agriculture, forest or mineral zones; and

            4.  Requiring tracts created through cluster development to be designated as permanent open space or as permanent resource use.

          B.   Use of this zone is appropriate in rural areas designated by the Comprehensive Plan as follows:

            1.  RA-2.5 in rural areas where the predominant lot pattern is below five acres in size for lots established prior to the adoption of the 1994 Comprehensive Plan;

            2.  RA-5 in rural areas where the predominant lot pattern is five acres or greater but less than ten acres in size and the area is generally environmentally unconstrained;

            3.  RA-10 in rural areas where the predominant lot pattern is ten acres or greater but less than twenty acres in size.  RA-10 is also applied on land that is generally environmentally constrained, as defined by county, state or federal law, to protect critical habitat and regionally significant resource areas (RSRAs).  The RA-10 zone is also applied to lands within one-quarter mile of a forest or agricultural production district or an approved long-term mineral extraction site.  On Vashon-Maury Island RA-10 zoning shall be maintained on areas zoned RA-10 as of 1994 and on areas with a predominant lot size of ten acres or greater that are identified on the Areas Highly Susceptible to Groundwater Contamination map; and 

            4.  RA-20 in Rural Forest Focus Districts designated by the King County Comprehensive Plan.  (Ord. 14045 § 1, 2001:  Ord. 11621 § 10, 1994:  Ord. 10870 § 27, 1993).


          21A.04.070  Urban reserve zone.

          A.  The purposes of the urban reserve zone (UR) are to phase growth and demand for urban services, and to reserve large tracts of land for possible future growth in portions of King County designated by the Comprehensive Plan for future urban growth while allowing reasonable interim uses of property; or to reflect designation by the comprehensive plan of a property or area as part of the urban growth area when a detailed plan for urban uses and densities has not been completed.  These purposes are accomplished by:

            1.  Allowing for rural, agricultural and other low-density uses;

            2.  Allowing for limited residential growth, either contiguous to existing urban public facilities, or at a density supportable by existing rural public service levels; and

            3.  Requiring clustered residential developments where feasible, to prevent establishment of uses and lot patterns which may foreclose future alternatives and impede efficient later development at urban densities.

          B.  Use of this zone is appropriate in urban areas, rural towns or in rural city expansion areas designated by the Comprehensive Plan, when such areas do not have adequate public facilities and services or are not yet needed to accommodate planned growth, do not yet have detailed land use plans for urban uses and densities, or are designated as sites for a potential urban planned development or new fully contained communities.  (Ord. 19146 § 19, 2020:  Ord. 13278 § 2, 1998:  Ord. 12171 § 2, 1996:  Ord. 11621 § 11, 1994:  Ord. 10870 § 28, 1993).


          21A.04.080  Urban residential zone.

          A.  The purpose of the urban residential zone (R) is to implement comprehensive plan goals and policies for housing quality, diversity and affordability, and to efficiently use urban residential land, public services and energy.  These purposes are accomplished by:

            1.  Providing, in the R-1 through R-8 zones, for a mix of predominantly single detached dwelling units and other development types, with a variety of densities and sizes in locations appropriate for urban densities;

            2.  Providing, in the R-12 through R-48 zones, for a mix of predominantly apartment and townhouse dwelling units, mixed-use and other development types, with a variety of densities and sizes in locations appropriate for urban densities;

            3.  Allowing only those accessory and complementary nonresidential uses that are compatible with urban residential communities; and

            4.  Establishing density designations to facilitate advanced area-wide planning for public facilities and services, and to protect environmentally sensitive sites from over development.

          B.  Use of this zone is appropriate in urban areas, activity centers, or rural towns designated by the comprehensive plan as follows:

            1.  The R-1 zone on or adjacent to lands with area-wide environmental constraints where development is required to cluster away from sensitive areas, on lands designated urban separators or wildlife habitat network where development is required to cluster away from the axis of the corridor on critical aquifer recharge areas, and on Regionally and Locally Significant Resource Areas (RSRAs/LSRAs) or in well-established subdivisions of the same density, which are served at the time of development by public or private facilities and services adequate to support planned densities;

            2.  The R-4 through R-8 zones on urban lands that are predominantly environmentally unconstrained and are served at the time of development, by adequate public sewers, water supply, roads and other needed public facilities and services; and

            3.  The R-12 through R-48 zones next to Unincorporated Activity centers, in Community or Neighborhood Business Centers, in mixed-use development, on small, scattered lots integrated into existing residential areas, or in rural towns, that are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services.  (Ord. 14045 § 2, 2001:  Ord. 12822 § 5, 1997:  Ord. 12596 § 2, 1997:  Ord. 11621 § 12, 1994:  Ord. 10870 § 29, 1993).


          21A.04.090  Neighborhood business zone.

          A.  The purpose of the neighborhood business zone (NB) is to provide convenient daily retail and personal services for a limited service area and to minimize impacts of commercial activities on nearby properties and in urban areas on properties with the land use designation of commercial outside of center, to provide for limited residential development. These purposes are accomplished by:

            1.  Limiting nonresidential uses to those retail or personal services which can serve the everyday needs of a surrounding urban or rural residential area;

            2.  Allowing for mixed use (housing and retail/service) developments and for townhouse developments as a sole use on properties in the urban area with the land use designation of commercial outside of center; and

            3.  Excluding industrial and community/regional business-scaled uses.

          B.  Use of this zone is appropriate in urban neighborhood business centers, rural towns, or rural neighborhood centers designated by the comprehensive plan, on sites which are served at the time of development by adequate public sewers when located in urban areas or adequate on-site sewage disposal when located in rural areas, water supply, roads and other needed public facilities and services. (Ord. 12522 § 2, 1996:  Ord. 11621 § 13, 1994:  Ord. 10870 § 30, 1993).


          21A.04.100  Community business zone.

          A.  The purpose of the community business zone (CB) is to provide convenience and comparison retail and personal services for local service areas which exceed the daily convenience needs of adjacent neighborhoods but which cannot be served conveniently by larger activity cen­ters, and to provide retail and personal services in locations within activity centers that are not appropriate for extensive outdoor storage or auto related and industrial uses.  These pur­poses are accomplished by:

            1.  Providing for limited small-scale offices as well as a wider range of the retail, professional, governmental and personal services than are found in neighborhood business areas;

            2.  Allowing for mixed use (housing and retail/service) developments; and

            3.  Excluding commercial uses with extensive outdoor storage or auto related and in­dustrial uses.

          B.  Use of this zone is appropriate in urban and community centers or rural towns that are designated by the Comprehensive Plan and community plans and that are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services.  (Ord. 11621 § 14, 1994:  Ord. 10870 § 31, 1993).


          21A.04.110  Regional business zone.

          A.  The purpose of the regional business zone (RB) is to provide for the broadest mix of comparison retail, wholesale, service and recreation/cultural uses with compatible storage and fabrication uses, serving regional market areas and offering significant employment opportunities.  These purposes are accomplished by:

            1.  Encouraging compact development that is supportive of transit and pedestrian travel, through higher nonresidential building heights and floor area ratios than those found in community centers;

            2.  Allowing for outdoor sales and storage, regional shopping areas and limited fabrication uses; and

            3.  Concentrating large scale commercial and office uses to facilitate the efficient provision of public facilities and services.

          B.  Use of this zone is appropriate in urban activity centers or rural towns that are designated by the Comprehensive Plan and community plans that are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services. (Ord. 11621 § 15, 1994:  Ord. 10870 § 32, 1993).


          21A.04.120  Office zone.

          A.  The purpose of the office zone (O) is to provide for pedestrian and transit-oriented high-density employment uses together with limited complementary retail and urban density residential development in locations within activity centers where the full range of commercial activities is not desirable.  These purposes are accomplished by:

            1.  Allowing for uses that will take advantage of pedestrian-oriented site and street improvement standards;

            2.  Providing for higher building heights and floor area ratios than those found in community centers;

            3.  Reducing the ratio of required parking to building floor area;

            4.  Allowing for on-site convenient daily retail and personal services for employees and residences; and

            5.  Excluding auto-oriented, outdoor or other retail sales and services which do not provide for the daily convenience needs of on-site and nearby employees or residents.

          B.  Use of this zone is appropriate in activity centers designated by the Comprehensive Plan and community plans which are served at the time of development by adequate public sewers, water supply, roads and other  needed public facilities and services.  (Ord. 10870 § 33, 1993).


          21A.04.130  Industrial zone.

          A.  The purpose of the industrial zone (I) is to provide for the location and grouping of industrial enterprises and activities involving manufacturing, assembly, fabrication, processing, bulk handling and storage, research facilities, warehousing and heavy trucking. It is also a purpose of this zone to protect the industrial land base for industrial economic development and employment opportunities.  These purposes are accomplished by:

            1.  Allowing for a wide range of industrial and manufacturing uses;

            2.  Establishing appropriate development standards and public review procedures for industrial activities with the greatest potential for adverse impacts; and

            3.  Limiting residential, institutional, commercial, office and other non-industrial uses to those neces­sary for the convenience of industrial activities. 

          B.  Use of this zone is appropriate in urban activity centers or rural towns designated by the Comprehensive Plan and community plans which are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services.  (Ord. 11621 § 16, 1994: Ord. 10870 § 34, 1993).


          21A.04.140  Map classification - regional use classification.  The purpose of the regional use classification (case file number following underlying zone's map symbol) is to provide for individual review of certain proposed uses with unique characteristics and adverse impacts on neighboring properties.  Regional uses are of a size and involve activities which require individual review to determine compatibility with surrounding uses.  (Ord. 19146 § 20, 2020:  Ord. 10870 § 35, 1993).


          21A.04.150  Map classification - property-specific development or P-suffix standards.  The purpose of the property-specific development standards classification (-P suffix to zone's map symbol) is to indicate that conditions beyond the minimum requirements of this title have been applied to development on the property, including but not limited to increased development standards, limits on permitted uses or special conditions of approval.  Property-specific development standards are adopted in either a reclassification or area zoning ordinance and are shown in a geographic information system data layer for an individual property maintained by the department. Regardless of the form in which a property-specific development standard is adopted, the P-suffix shall be shown on the official zoning map maintained by the department and as a notation in a geographic information system data layer, which shall be updated as soon as possible after the effective date of the adopting ordinance adopting a P-suffix standard.  (Ord. 19146 § 21, 2020:  Ord. 17485 § 12, 2012:  Ord. 12824 § 20, 1997:  Ord. 11621 § 17 1994:  Ord. 10870 § 36, 1993).


          21A.04.160  Map classification - special district overlay or SO-suffix classification.  The purpose of the special district overlay classification (-SO suffix to zone's map symbol) is to carry out Comprehensive Plan and community, subarea or neighborhood plan policies that identify special opportunities for achieving public benefits by allowing or requiring alternative uses and development standards that differ from the general provisions of this title.  Special district overlays are generally applied to a group of individual properties or entire community, subarea or neighborhood planning areas and are classified primarily through the area zoning process.  Regardless of the form in which a special district overlay is adopted, the -SO suffix shall be shown on the official zoning map maintained by the department and as a notation in a geographic information system data layer, which shall be updated as soon as possible after the effective date of the adopting ordinance adopting an overlay.  (Ord. 19146 § 22, 2020:  Ord. 17485 § 13, 2012:  Ord. 12823 § 1, 1997:  Ord. 11621 § 18, 1994:  Ord. 10870 § 37, 1993).


          21A.04.170  Map classification - special zone classification.

          A.  The purpose of the potential zone (dashed box surrounding zone's map symbol) is to classify properties potentially suitable for future changes in land uses or densities once additional infrastructure, project phasing or site-specific public review has been accomplished.  Potential zones are classified by either area zoning or individual zone reclassification.  Area zoning may classify more than one potential zone on a single property if the community plan designates alternative uses for the site.  Potential zones are actualized in accordance with  K.C.C. chapter 20.20.

          B.  The use of a potential zoning classification is appropriate to:

            1.  Phase development based on availability of public facilities and services or infrastructure improvements, such as roads, utilities and schools;

            2.  Prevent existing development from becoming a nonconforming use in areas that are in transition from previous uses;

            3.  Allow for future residential density increases consistent with a community plan; and

            4.  Provide for public review of proposed uses on sites where some permitted uses in a zoning classification may not be appropriate.  (Ord. 19146 § 23, 2020:  Ord. 18230 § 126, 2016:  Ord. 10870 § 38, 1993).


          21A.04.180  Map classification - interim zoning classification.  The purpose of the interim zoning classification (* suffix to zone's map symbol) is to identify areas where zoning has been applied for a limited period of time in order to preserve the county's planning options and to protect the public safety, health and general welfare during an emergency or pending a community, comprehensive or functional plan amendment process.  Any of the zones set forth in this chapter, with or without -P suffix conditions, may be applied as interim zones.  The adopting ordinance shall state the reasons for the interim zoning and provide for its expiration upon a certain date or the adoption of a new plan, plan amendment or area zoning.  (Ord. 19146 § 24, 2020:  Ord. 10870 § 39, 1993).


          21A.04.190  Zoning maps and boundaries.

          A.  The location and boundaries of the zones defined by this chapter shall be shown and delineated on zoning maps adopted by ordinance.

          B.  Changes in the boundaries of the zones, including application or amendment of interim zoning, shall be made by ordinance adopting or amending a zoning map.

          C.  Zoning maps are available for public review at the department of local services, permitting division, permit center during business hours.  (Ord. 18791 § 162, 2018:  Ord. 17420 § 96, 2012:  Ord. 10870 § 40, 1993).
