King City — Development Standards
Development Standards under the King City local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
This page summarizes what King City’s zoning ordinance (Title 17) actually requires for development standards: setbacks, height, lot coverage, minimum lot size, density and related controls. For background rules about where zones and map designations live, see zoning. Requirements below are taken directly from the City’s ordinance and cited to the controlling code section (§) and to the retrieved ordinance file. For on-site vehicle counts and layout rules consult the City’s parking chapter.
How to read this page
- Bolded terms are the code names you’ll see on the zoning map (for example, R‑1, C‑2).
- Each district subsection gives the official purpose, typical permitted uses (as stated in Title 17), and the key measurable development standards (height, setbacks, lot coverage, minimum lot size or lot width, density if in code). Each measured standard is anchored to the controlling §. File citation markers from the retrieved code are included for each citation (for example, ).
District-by-district development standards (selected districts)

- Parking and on‑site layout: industrial parking and access standards with specific ratios and off‑site rules are in Chapter 17.52, which is referenced throughout the industrial chapters — § 17.30.140, § 17.52.030 .
O (Open Space) and P‑D (Planned Development)
- O preserves open space and sets special minimums (e.g., golf course 5 acres; crop/tree farming 1 acre) and ties parking/yards/height to a use permit — § 17.34.040 .
- P‑D allows site‑specific plan standards; P‑D development standards are established by the approved plan and must still meet required chapters unless modified in the P‑D approval — § 17.33 .
Accessory Dwelling Units (ADUs) and Second Units
- King City’s ADU chapter (17.47) sets ADU maximums and objective development standards (size limits, 16 ft / 1 story height for ADUs in many cases, 4 ft side/rear setbacks unless conversion/existing) — § 17.47.010–17.47.040 and Table 17.47‑1 .
- Separate second‑unit chapter (17.80) implements ministerial review rules and size/parking/height thresholds for second units and two‑unit developments — § 17.80.020–17.80.040 .
(For ADU ministerial rules see the ADUs page.)

Checklist (what an applicant must demonstrate)
- Verify base zoning and applicable overlays (including airport/approach overlays) and read the district chapter that controls the parcel — start with King City Zoning and Overlay Districts.
- Confirm permitted use or need for a use permit/CUP; check Chapter 17.60 (permits) and any P‑D approvals — § 17.60 (See applicable district sections) .
- Show compliance with numeric development standards: setbacks, height, lot coverage, minimum lot size (cite the district section: e.g., § 17.12.060–.080 for R‑1) .
- Provide off‑street parking per Chapter 17.52 and make layout meet Chapter 17.52 rules — check parking for ratios and placement — § 17.52.020–.032 .
- If multi‑unit or commercial: submit elevations, site plans, landscaping plan and architecturals for architectural committee/design review — see design review rules in § 17.50.010–.020 .
- If proposing ADU/second unit: follow ministerial ADU standards in § 17.47 and second unit ministerial rules in § 17.80 — ADU table and size/parking rules apply .
- If relying on optional design/improvement standards (subdivision plan or P‑D), include the approved plan showing substituted numeric standards and cite § 17.12.110 / 17.26.110 / 17.30.110 where relevant .
- For stormwater/landscape/site BMPs, provide landscaping and stormwater plans and comply with City Engineer / RWQCB direction — see development standards and LID references (§ 17.30.130, etc.) .
- Verify whether a Use Permit, Variance, or other discretionary action is required and be prepared to supply the exhibits/fees per Title 17 — see Variances and Exceptions and permit chapters.
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Floor‑Area Ratio (FAR) or explicit FAR limits | King City code excerpts returned do not set a city‑wide FAR in the district chapters; some projects rely on FAR to size building massing | FAR: Not found in retrieved materials for general zones — Verify with Community Development if FAR or an equivalent bulk control exists for your parcel (specific plan or P‑D may impose one). |
| Density calculations (which “gross area” to use) | Code references gross‑area‑per‑unit rules in places (R‑3, R‑4, condominiums). Different sections define “gross area” differently | Confirm which section applies (e.g., § 17.16.130 for R‑3; condominium conversions have particular density rules § 17.49.040) and whether ADUs are counted separately. |
| Front‑setback averaging and lot‑by‑lot exceptions | § 17.48.160 allows averaging where >50% of lots were improved at passage — this can change the numeric requirement on a specific block | Check block‑level historic improvements and determine whether plan‑line averaging applies to your lot — see § 17.48.160. |
| Optional design/PD substitution of numeric standards | Subdivisions/P‑D plans can replace district numbers; relying on an old plan without verifying current approvals causes compliance problems | Confirm whether an approved plan or PD overlay applies to parcel and which sections it supersedes (§ 17.12.110, § 17.24.110, § 17.30.110). |
| Historic/resource limitations on ADUs and demolitions | ADU rules specifically prohibit ADUs in historic districts or where demolition would violate historic protections | If property is in a historic district or on state/local register, ADU eligibility and demolition rules differ — verify historic status; ADU limits in § 17.47 and exceptions in ADU subsection apply. |
| Parking reductions and off‑site parking | Some zones allow off‑site parking within 300 ft with approval or reductions (especially industrial/large projects) | Verify whether you need a parking use permit or planning commission approval for off‑site parking — see Chapter 17.52 and industrial parking sections § 17.52.032 / § 17.31.140. |
Plain‑English summary
King City’s zoning (Title 17) sets explicit numeric rules by zone (height usually 2 stories / 30 ft, setbacks commonly 20 ft front / 6 ft side / 10 ft rear in single‑family zones, lot coverage commonly 40–60% depending on zoning); ADUs and second units have their own ministerial tables and backyard setbacks; parking is controlled by Chapter 17.52 and multi‑unit/commercial projects require architectural/site plan review. Always check the specific zone chapter (e.g., § 17.12 for R‑1, § 17.16 for R‑3) and verify any overlay or P‑D plan that may replace the numeric standards. For design review steps see the City’s design review procedures.

Frequently asked questions
What can I build on an R-1 lot in King City?
You can build a single‑family dwelling and customary accessory buildings; numeric limits are in § 17.12: minimum building site 6,000 sq ft, front setback 20 ft, side 6 ft interior, rear 10 ft, and maximum lot coverage 40%. For the full list of permitted accessory uses and fence rules see § 17.12.060–.090 .
What are King City setback requirements for single‑family homes?
Base setbacks for R‑1 (single family) are 20 ft front, 6 ft side (interior), 10 ft rear; the planning commission can allow minor front‑setback variations down to 17 ft or 15 ft on cul‑de‑sacs — see § 17.12.080 .
What is the maximum height allowed in residential zones?
Most residential chapters set a two‑story / 30 ft maximum for main buildings (for example § 17.16.050 for R‑3 and § 17.18.050 for R‑4). Accessory buildings often have a lower cap (commonly 14 ft) — see the applicable district section (e.g., § 17.16.050, § 17.18.050) .
Do I need design review or architectural approval?
Many multi‑unit, commercial, and certain residential projects must submit elevations, site plans and landscaping for architectural committee or planning commission approval — see § 17.50.010–.020 and district sections that reference architectural review. Smaller single‑family additions may be exempt depending on scope; verify with the Community Development Department — § 17.50.010 .
How much parking do I have to provide?
Parking ratios and design standards live in Chapter 17.52 and are referenced in each district (for example § 17.12.120, § 17.24.120, § 17.16.120). Off‑street parking must be accessible and usually cannot be in required yards; industrial and special projects have additional ratios and can allow off‑site parking within 300 ft with approval — see § 17.52.020–.032 .
What are the ADU rules in King City?
ADUs and junior ADUs must meet Chapter 17.47: size caps (e.g., up to 850–1,000 sq ft depending on bedrooms), 16 ft / one‑story maximum for many detached ADUs, and 4 ft side/rear setbacks except where conversion of an existing permitted structure occurs (then existing setbacks may govern). ADUs are ministerial where state law applies — see § 17.47 and Table 17.47‑1 .
Is there a Floor‑Area Ratio (FAR) limit in King City?
FAR is not generally presented as a city‑wide numeric in the district chapters returned; most bulk controls are by height, setbacks, coverage and per‑unit gross‑area rules. FAR: Not found in retrieved materials as a standard across the zones — verify with the City for parcel‑specific specific plans or P‑D conditions. .
Can a subdivision or PD plan change the numeric standards?
Yes. Optional design and improvement standards approved as part of a subdivision or P‑D can establish substituted building site, coverage and yard requirements; see the “optional design standards” sections such as § 17.12.110, § 17.24.110, § 17.30.110 — those approved plans become the controlling requirement for that development area. .
Do historic properties have exceptions for ADUs or demolition?
Yes. The ADU rules specifically prohibit locating an ADU where it would require demolition or alteration of housing that is rent‑restricted or within a historic district/listed historic inventory. See ADU chapter and the specific demolition limits in § 17.47 and related provisions. Verify historic status before planning demolition or ADU construction — § 17.47 .
Who enforces the setbacks, plan lines, and nonconforming issues?
Enforcement and interpretation of plan lines and yard measurements are managed under Chapter 17.48, and nonconforming use/structure rules are in Chapter 17.58; exceptions may be applied by the planning commission via the permits/variance process — see § 17.48.130–.160, § 17.58.010–.090 . ---
