Cupertino — Development Standards

Last reviewed: July 2, 2026

Overview

This page summarizes development standards (setbacks, height, lot coverage, density/FAR and related rules) that control what can be built in Cupertino under the city's zoning ordinance (Title 19). It synthesizes the code by district so applicants can quickly find the controlling numeric standards and the exact code sections to read. For procedural items that cross into parking, design review, overlays, or ADU-specific rules see the related topic pages linked inline below.

The city's land-use structure is in the Cupertino Zoning and Cupertino Land Use framework; parking standards are in Cupertino Parking; ADU rules are summarized on the Cupertino ADUs page; design review expectations are on Cupertino Design Review; and overlay rules live on Cupertino Overlay Districts. Technical building-code matters remain under the California Building Standards Code.

How to read this page

• Every numerical requirement below is tied to the ordinance section where it appears (bolded § references).
• Where the uploaded ordinance text did not include a rule, I state "Not found in retrieved materials" rather than guessing.
• Verify parcel-specific results with the City — this page summarizes the ordinance but cannot substitute for a site-specific staff check.

District-by-district development standards (Cupertino Title 19)

Note: Each district subsection lists the district name (bold), a one-line purpose, typical permitted uses (high-level), then the key dimensional controls you will use when preparing plans. Every standard below is tied to the City code section cited.

Agricultural — A and A‑1

• Purpose / typical uses: Preserve agricultural uses and large-lot residential/agricultural parcels; farm uses and low-density homes. See Table 19.24.050. § 19.24.050 .
• Key dimensional standards:
  • Maximum lot coverage: 40% (A) and 40% (A‑1) of net lot area. § 19.24.050 .
  • FAR: 45% for A‑1 (listed as Floor Area Ratio). § 19.24.050 .
  • Setbacks (first and second floor): Front 30 ft, Side 20 ft, Rear 20–25 ft depending on A vs A‑1. § 19.24.050 .
  • Height (principal): Generally 28 ft; exceptions for hillside areas with findings up to 35 ft rarely allowed. § 19.24.050 .
• Where it applies: parcels zoned A or A‑1 per zoning map. See the zoning map in Cupertino Zoning.

Single‑Family Cluster — R1C

• Purpose / typical uses: Clustered single‑family residential planned under a development plan; used where lot patterns/topography justify alternative layouts. See Table 19.44.050/060. § 19.44.050 and § 19.44.060 .
• Key dimensional standards:
  • Corner lot front setback: 25 ft; 40‑ft corner triangle must remain clear. § 19.44.060 .
  • Second‑story decks/patios: Front may encroach 3 ft; Side 15 ft; Rear 20 ft. § 19.44.060 .
  • Height: 30 ft typical; height increases require Planning Commission/City Council finding. § 19.44.060 .
• Where it applies: properties specifically zoned R1C. Development plans required per the R1C chapter. § 19.44.050 .

Single‑Family (general R‑1) — Not fully excerpted

• Purpose / typical uses: conventional single‑family residential. Specific R‑1 numeric table was not present in the uploaded snippets. Not found in retrieved materials. Verify with the City for exact R‑1 front/side/rear setbacks and lot coverage (see Cupertino Zoning).

Multifamily — R‑3 (and varying multifamily tables)

• Purpose / typical uses: low- to mid‑density multiple‑family housing. See § 19.36.060 and § 19.36.070 for site and building development regulations. § 19.36.060 and § 19.36.070 .
• Key dimensional standards (summary of the tables):
  • Maximum lot coverage: 50% (projects up to 4 units) and 55% (projects with 5+ units), unless inconsistent with State law (Gov. Code 65913.11). § 19.36.070 .
  • Maximum height: Generally 30 ft (two stories) for small projects; for larger projects heights may be guided by the General Plan (Figure LU‑2). § 19.36.070 .
  • Front setback: 20 ft typical for first floor; when abutting arterials/collectors different measurement rules apply (e.g., 35 ft from face of curb on arterials for some upper floors). § 19.36.070 .
  • Side yards: interior 6–10 ft depending on project size/number of units; street side 12 ft or 18 ft for upper floors. § 19.36.070 .
  • Rear yard: ranges 20–30 ft and additional stepbacks for higher floors. § 19.36.070 .
  • Density: Maximum number of units is controlled by the General Plan; the code defers to General Plan density and minimums. § 19.36.060(A) .
• Where it applies: parcels zoned R‑3. See the multi‑family tables in § 19.36.060–070. § 19.36.060–070 .

Townhomes / R‑3/TH and R‑4/TH (townhome overlays)

• Purpose / typical uses: attached housing in townhome form; design standards tuned to street frontage and unit type. See § 19.46.070 and related townhome tables. § 19.46.070 .
• Key standards:
  • Maximum lot coverage: 55% prior to development (townhome-specific table). § 19.46.070 .
  • Maximum FAR (building area): 85% of net lot area (townhome table). § 19.46.070 .
  • Maximum height: 3 stories (not to exceed 30 ft). § 19.46.070 .
  • Side yards & rear yards: townhome tables reference underlying multiple‑family district for front setbacks; interior side 6 ft with additional offsets when greater than adjacent structures. § 19.46.070 .
• Where it applies: parcels specifically mapped R‑3/TH or R‑4/TH. § 19.46.070 .

Residential Hillside — RHS

• Purpose / typical uses: manage development on steep slopes and ridgelines with special stepping, offsets and reduced footprints. See Chapter 19.40 (RHS) excerpts in the file bundle. § 19.40. .
• Key dimensional standards (common items found in the code):
  • Setback/offsets: front 10–20 ft depending on slope (< or > 20%); second/third‑story offsets and a minimum 5 ft second‑story offset average for downhill facing walls; maximum exposed wall height on downhill side 15 ft. § 19.38.070 and related RHS tables. § 19.38.070 .
  • Height: many RHS rules keep principal building height to 30 ft or less; additional limits and ridge protection rules apply (see RHS chapter). § 19.38.070 .
  • FAR adjustments: cluster developments and slope adjustments affect FAR caps; e.g., a maximum 45% FAR (pre‑slope adjustment) for cluster lots prior to slope considerations. § 19.136 (cluster/FAR tables) .
• Where it applies: mapped RHS hillside parcels and any site subject to the RHS chapter. § 19.40 .

General Commercial — CG

• Purpose / typical uses: retail and service commercial uses; retailing and related business activities are regulated by Chapter 19.60. § 19.60.050–060 .
• Key dimensional standards:
  • Lot area / coverage: No minimum lot area/coverage specified in the CG table, unless the General Plan or a specific plan imposes one. § 19.60.060(A) .
  • Height: 30 ft unless the General Plan or a specific plan allows different heights. § 19.60.060(B) .
  • Side/rear yards adjacent to residential zones: Interior side 12 ft (or formulaic increase based on building height); rear yard 20 ft (or height‑based formula). § 19.60.060(C)(2) .
  • Noise & loading: Special noise attenuation and loading dock siting rules for uses adjacent to residential zones. § 19.60.060(D) .
• Where it applies: parcels mapped CG and subject to Chapter 19.60. § 19.60.060 .

Business/Transit/Flex — BA, BQ, T

• Purpose / typical uses: business park, office/technology, transit‑oriented or special employment areas with flexible development plans. See § 19.76.060. § 19.76.060 .
• Key points:
  • No minimum setbacks established in the chapter by default; the Planning Commission sets setbacks per development plan to ensure light, air and compatibility. § 19.76.060 .
  • Height: regulated by the approved development plan rather than rigid numeric maximums in the chapter; the Planning Commission establishes limits. § 19.76.060 .
• Where it applies: BA, BQ and T zoning districts. § 19.76.060 .

Planned Development — P

• Purpose / typical uses: custom, plan‑level flexibility for large or special projects; the PD allows the city to set site‑specific standards by ordinance or PD plan. § 19.80.010–030 .
• Key points:
  • Standards established by approved PD documents (the ordinance or development plan will list permitted uses and numeric standards). § 19.80.030 .
  • Applicability: every use and building must conform to the PD plan and conditions; you cannot rely on the base zone standards if the PD establishes different controls. § 19.80.020–030 .

Quick standards table (most decision‑relevant at a glance)

Accessory dwelling units (ADUs) — highlights

• Streamlined ADU standards (tables) are in § 19.112.030; non‑streamlined rules are in § 19.112.040. The City expressly allows ADUs subject to the smaller of the underlying zoning standards or the ADU chapter exceptions; some ADU‑specific minimums (e.g., 4 ft side/rear for streamlined 800 s.f. units) are protected by state law and implemented in the ADU chapter. § 19.112.030–040 .
• Common ADU numeric notes in the code:
  • Detached ADU height: typically 18 ft when allowed in the streamlined path; attached ADU limited to 25 ft or existing primary dwelling limit. § 19.112.030 / § 19.112.040 .
  • Setbacks: ADUs follow the underlying district setbacks except where the ADU chapter allows 4 ft side/rear setbacks for qualifying units. § 19.112.030 .
• For ADU submission requirements and the streamlined checklist, see the Cupertino ADUs page and the ADU chapters § 19.112.030–040. § 19.112.030–040 .

Checklist (what an applicant must satisfy for site plan submittal)

• Confirm the property’s zoning district and any mapped overlays (verify allowed uses and any overlay standards) — see the zoning map and Cupertino Overlay Districts. Verify with staff. § 19.80.030 .
• Confirm applicable numeric standards from the district table: height, lot coverage, setbacks, FAR/density — use the district sections cited above (e.g., § 19.36.060–070 for R‑3). § 19.36.060–070 .
• Show compliance with ADU chapter if proposing an ADU; invoke the ADU streamlined or non‑streamlined table as appropriate (§ 19.112.030–040). § 19.112.030–040 .
• Prepare parking and loading that meet the off‑street parking chapter rules — consult Cupertino Parking and Chapter 19.124 references found in district tables. § 19.36.070(H) .
• If in a district requiring design review or PD approval, prepare materials to satisfy Cupertino Design Review standards and any PD plans (§ 19.80.020). § 19.80.020 .
• Document any slope, FAR cluster calculation or RHS offsets if the site is steep — see the RHS and cluster FAR rules (§ 19.38.070, § 19.136 for cluster/FAR adjustments). § 19.38.070 .
• Confirm whether a height exception or variance is needed; if so, review the height exception findings (§ 19.136.090) and variance rules. § 19.136.090 .

Risks & Ambiguities

Plain‑English summary

Cupertino’s Title 19 sets district‑specific numeric rules (height, setbacks, lot coverage and FAR/density) that differ by zone: small multifamily projects have stricter side/rear offsets and coverage caps than larger projects, ADUs have their own streamlined minimums, and hillside/PD areas use bespoke rules — always read the district table that applies to your parcel and confirm overlay or PD exceptions with staff. Key code starting points are § 19.24.050, § 19.36.060–070, § 19.38.070, § 19.60.060, and § 19.112.030–040. § 19.24.050 § 19.36.060–070 § 19.112.030–040
