King City — Land Use

Last reviewed: July 2, 2026

Overview

King City regulates land use through its zoning ordinance (Title 17). The code organizes the city into discrete districts (for example R-1, R-2, C-2, M-1/M-2/M-3, O, S-C) and ties each district to specific permitted uses, uses that require a conditional use permit, and district development standards. For practical applications you must check code limits on parking, design review, overlay controls, and accessory units — the ordinance refers applicants to local development standards and to the state building code for construction compliance. See King City’s local pages on development standards, parking, design review, overlay districts, ADUs, and the California Building Standards Code for related procedures: King City Development Standards, King City Parking, King City Design Review, King City Overlay Districts, King City ADUs, and California Building Standards Code. (Ordinance citations below: for example § 17.12.010 for R‑1.)

Below is a district-by-district synthesis of what Title 17 actually says about permitted uses and the most decision-relevant quantitative standards. I interpret and compare the rules so you can quickly see what is allowed as-of the ordinance text; I do not reproduce long verbatim code excerpts — see the Source References for the controlling § citations.

R-1 — Single-Family Residential

• Purpose: The R-1 district is intended for single‑family homes with not more than one dwelling and customary accessory buildings on a lot. § 17.12.010.
• Typical permitted uses: single‑family dwellings and customary accessory uses; ADUs/JADUs are addressed by Chapter 17.47 (see the ADU page). § 17.12.010; ADU rules: § 17.80.040 and Chapter 17.47.
• Key dimensional standards & rules: The R‑1 chapter incorporates the general provisions in Chapters 17.48–17.52 (yards, coverage, accessory buildings). Specific lot/yard numbers are in the R‑1 chapter and cross references; where average setbacks exist the code uses the block-average rule in § 17.48.160. § 17.12.010; § 17.48.160.
• Where it applies: All areas shown on King City’s zoning map that are labeled R‑1 (verify parcel zoning with the city). Verify with the jurisdiction.

R-2 — Medium Density Residential

• Purpose: The R-2 district permits higher density residential (duplexes/triplexes) while maintaining privacy and open space. § 17.14.010.
• Typical permitted uses: single‑family dwellings, duplexes, triplexes, accessory dwelling units and junior ADUs (in conformance with Chapter 17.47), home occupations. § 17.14.020.
• Key dimensional standards: Minimum front yard: 20 ft (subject to planning commission adjustment and averaging rules), maximum lot coverage: 40%, max height: 2 stories / 30 ft; minimum lot sizes: 6,000–7,000 sq ft depending on interior/corner lots. § 17.14.050–.070.
• Uses requiring a permit: two single‑family structures, churches, schools, parking lots adjacent to commercial/industrial zones, etc. § 17.14.030.

R-3 — Medium‑High Density Residential

• Purpose & uses: R-3 allows multi‑family and small family living, including apartments and townhouses; ADUs/JADUs allowed per Chapter 17.47. § 17.16.010–.020.
• Standards: R‑3 has its own yard/height and coverage standards and requires planning review for larger apartment projects; see § 17.16.030–.040.

R-4 — High Density / Apartment‑oriented

• Purpose & uses: R-4 permits single‑ and multi‑family dwellings (including apartments under 22 units/acre), schools, churches, accessory units, and ADUs per Chapter 17.47. § 17.18.020.
• Standards: Max building height: 2 stories / 30 ft (main building); accessory buildings lower; minimum lot sizes for various public uses are specified. § 17.18.050–.060.

C-2 — General Commercial

• Purpose: The C-2 (General Commercial) district supports a wide range of commercial, professional, storage, some light industrial and mixed residential uses. § 17.24.010.
• Typical permitted uses: wholesale stores, light manufacturing, printing, indoor vehicle sales/service, building materials in buildings, secondhand within buildings, research and development and others listed in § 17.24.020.
• Uses requiring CUP: outdoor sales yards, gasoline service stations, certain outdoor auto sales, caretakers’ residences, and others listed in § 17.24.030. § 17.24.030.
• Development standards (representative): Maximum building height: 30 ft, minimum lot: 5,000 sq ft (service stations larger), maximum lot coverage: 60%, and minimum yards: generally 0 ft unless adjacent to R zones — see Table 17.24‑1 and § 17.24.070–.080. § 17.24.070.

M-1 — Light Industrial (and Transitional)

• Purpose & uses: M‑1 supports light manufacturing, warehousing, contractor yards, and similar industrial support uses. Some types of cannabis manufacturing/testing are explicitly permitted in industrial zones per the ordinance (subject to state licenses). § 17.30.010; § 17.03.270.
• Not allowed: a list of heavy or hazardous manufacturing activities is excluded (e.g., asphalt mixing, explosives, certain chemical productions) — see § 17.30.030.
• Accessory uses and building rules: accessory buildings allowed if built with or after the main building; height and site rules are in the M‑1 chapter. § 17.30.040.

M-2 — Industrial

• Purpose: M‑2 for sound industrial development that should be separated from non‑industrial uses. § 17.31.010.
• Uses: many manufacturing/processing and warehousing uses are allowed subject to use permit — see § 17.31.020 for the list of CUP uses. § 17.31.020.
• Prohibitions & standards: M‑2 excludes specific offensive industries; accessory buildings allowed only with the main building; parking standards for industrial uses are in § 17.31.140. § 17.31.030–.040; § 17.31.140.

M-3 — Heavy Industrial / Airport‑Combining

• Purpose & uses: M‑3 is for heavy industrial uses and includes airport overlay constraints; many M‑1/M‑2 CUP uses allowed, plus heavy items like concrete batch plants with strict performance standards. § 17.32.010–.020.
• Standards: minimum building site sizes and yard rules (front yard 10 ft, side/rear often none) are specified; landscaping and architectural approvals required. § 17.32.060–.130.

O — Open Space

• Purpose & uses: The O district preserves rural and natural open space (crop/tree farming, parks). § 17.34.010–.020.
• Uses needing CUP: golf courses, private parks, structures accessory to open space, riding/hiking trails; development standards specify minimum parcel sizes for particular uses. § 17.34.030–.040.

S‑C — Scenic Corridor (Overlay)

• Role: The S‑C district is a combining (overlay) district applied with basic districts. It adds requirements (e.g., development plans, additional yards) and is explicitly supplemental to the base zone: § 17.42.020–.040. Bold: overlay districts can be more restrictive than base district rules — check the overlay.

Quick reference table — most decision‑relevant permitted uses & standards

Checklist

• Confirm parcel zoning on the King City zoning map and identify the base district (e.g., R‑1, C‑2, M‑1). Verify with the jurisdiction. § 17.02.010.
• Read the district’s permitted uses list and CUP list for that district (e.g., § 17.12.010 for R‑1, § 17.24.020–.030 for C‑2).
• Check dimensional standards: setbacks, height, lot size, lot coverage from the district's development standards or from Table 17.24‑1 for C‑2. § 17.24.070.
• Confirm parking requirements under Chapter 17.52 and district-specific parking tables (industrial parking rates § 17.31.140). King City Parking § 17.31.140.
• If proposing an ADU/JADU, follow Chapter 17.47 and ADU development standards in § 17.80.040; check parking exceptions and state ADU law interaction. King City ADUs § 17.47; § 17.80.040.
• Determine whether design review is required (architectural/site plan approvals are required in many districts; see architectural review/committee references in relevant zone chapters). King City Design Review Verify with the community development department.
• Confirm whether overlay or combining districts (e.g., S‑C, airport combining) change the base rules. King City Overlay Districts § 17.42.020–.040.
• For special uses (e.g., commercial cannabis, concrete batch plants, heavy industrial), confirm the code’s explicit allowances and prohibitions and the required CUP or other permits. § 17.03.260–.270; § 17.30.030; § 17.31.020.

Risks & Ambiguities

Plain‑English Summary

King City’s Title 17 assigns each parcel to a specific zone (R‑1, R‑2, C‑2, M‑1/M‑2/M‑3, O, S‑C, etc.) and lists what you can do by right, what requires a conditional use permit, and the key size/setback/height rules; for homes, ADUs are allowed under Chapter 17.47 and ADU development standards § 17.80.040; for businesses and industry the code specifies allowed operations and explicit prohibitions (e.g., certain hazardous manufacturing and outdoor cannabis cultivation). Always confirm the parcel zoning, overlays, and whether a CUP or design review is required before you finalize plans.
