Cupertino — Zoning

Last reviewed: July 2, 2026

Overview

This page summarizes how the City of Cupertino structures and enforces land-use zoning under Title 19 of the Municipal Code. It explains the base districts and combining/special districts used on the City zoning map, where to find permitted uses and dimensional controls, and practical items applicants must check before proceeding. Key rules on the zoning map, district boundaries, and “what each zone allows” are adopted as part of Title 19 and enforced citywide (§ 19.16.030, § 19.16.050).

How Cupertino organizes zoning (quick orientation)

• The City’s base districts are listed in Table 19.16.010A (examples: R-1, R-2, R-3, R-4, CG, ML, OS, P, etc.) and each base district has its own chapter in Title 19. (§ 19.16.010).
• The zoning map and any amendments are part of the zoning title; where the map does not show a district the default is R-1 single‑family. (§ 19.16.030; § 19.16.040).
• Rules for resolving mapping/boundary uncertainty (centerlines, street/alley lines, scale) are spelled out in § 19.16.050; when ambiguous the Director of Community Development is the decision authority. (§ 19.16.050; § 19.16.060).

Note: where Title 19 refers you to a chapter for uses (for example residential uses are listed in Chapter 19.20) consult that chapter for the detailed permitted/conditional/excluded lists. (§ 19.20.010 - 19.20.020).

District-by-district breakdown (purpose, typical uses, key dimensional standards, where it applies)

The entries below are condensed, plain-English syntheses of the controlling Title 19 chapters. For parcel-specific questions, Verify with the jurisdiction.

R-1 — Single‑Family Residential

• Purpose: preserve single‑family neighborhoods and control scale and compatibility (§ 19.28.010).
• Typical permitted uses: single‑family dwellings, accessory uses (see Chapter 19.20 for full lists). (§ 19.20.010).
• Key dimensional standards: maximum height 28 ft / two stories (unless an “i” suffix limits to one story / 18 ft); minimum first‑floor front setback 20 ft (R1‑a is 30 ft); minimum side/rear setbacks commonly 4 ft but see exceptions and the building envelope rules in § 19.28.070. (§ 19.28.070).
• Where it applies: citywide single‑family neighborhoods and any parcels zoned R-1 on the zoning map; unspecified areas default to R-1. (§ 19.16.040; § 19.16.010).

When you are assessing an R-1 project, confirm whether the parcel carries an “i” suffix or other overlay — that suffix can change max stories, setbacks, and processing (see § 19.28 and the notes on the “i” suffix).

R-2 — Residential Duplex

• Purpose: allow detached or attached duplex development with rules adapted to two‑unit projects (§ 19.32.010 & 19.32.060).
• Typical permitted uses: duplexes and accessory uses listed in Chapter 19.20. (§ 19.20.010).
• Key dimensional standards (Table 19.32.060): max lot coverage 40%, max height two stories / 30 ft, front setback 20 ft, side/rear setbacks and special second‑story offsets (interior side often 20% of lot width / min 6 ft; rear 20 ft or 20% of lot depth; see table). (§ 19.32.060).
• Where it applies: parcels identified R-2 on the zoning map. (§ 19.16.010).

R-3 — Medium / Medium‑High Multiple‑Family Residential

• Purpose: permit medium to high density multifamily housing, with development plan process for larger projects (§ 19.36.010–.050).
• Typical permitted uses: see Chapter 19.20; the permitted/conditional/excluded uses are cross‑referenced there (§ 19.36.030 → § 19.20.020).
• Key standards: R-3 requires a development plan and development permit for most new projects; the Community Development Director may set application requirements; density, setbacks and height limits are controlled in Chapter 19.36 and related tables. (§ 19.36.040–.050).
• Where it applies: sites zoned R-3 on the mapping layer and any P zones that reference R-3 as their residential component. (§ 19.16.010; § 19.80.030).

R-4 — High / Very High Density Multiple‑Family Residential

• Purpose: accommodate very high density housing; similar processing to R-3 with stricter density allowances (§ 19.38.010–.050).
• Typical permitted uses: cross‑referenced to § 19.20.020 for permitted/conditional/excluded uses; development plans required for most new development. (§ 19.38.030–.050).

P (Planned Development) — Flexible / Mixed Use or Master‑Planned Parcels

• Purpose: a flexible district that is designated P plus a parent zone (for example P(CG) or P(CG, R-3)) and allows tailored standards via conceptual/definitive development plans (§ 19.80.010–.050).
• Typical permitted uses: the permitted uses in the referenced district apply unless the conceptual plan restricts them; e.g., P(CG) uses are the same as CG unless otherwise stated (§ 19.80.030).
• Key process: prezoning/zoning to P requires a conceptual development plan and findings including General Plan consistency, circulation, parking and open space provisions; a development permit is required before building. (§ 19.80.040–.050).

CG (General Commercial), ML (Light Industrial), BA/BQ/T (Public/Quasi/Public/Transportation), OS/PR/FP (Open Space & Parks) — non‑residential base districts

• Purpose & uses: each district chapter sets the scope (e.g., CG for general commercial trade, ML for light industrial). Refer to Table 19.16.010A for the district list and each chapter for permitted uses. (§ 19.16.010; see chapters such as 19.60, 19.72, 19.76, 19.88, 19.92, 19.96).
• Special development standards: some districts (BA, BQ, T) have no minimum standard setbacks and rely on plan review to set setbacks and heights; when applicable the Planning Commission may adopt setbacks per project. (§ 19.76.060).

Combining and Special Districts

• TH (Townhome combining district): modifies R-3 or R-4 sites to allow townhome configurations; Table 19.46.070 sets lot coverage, max height typically 3 stories / 30 ft, and stepback/setback rules. (§ 19.46.070).
• Specific plans (for example Heart of the City) create their own zoning districts and may supersede Title 19 where they conflict. (§ 19.16.010C).

Key quick‑reference table (most decision‑relevant standards)

Practical guidance & links (where to look next)

• Confirm the parcel zoning and any suffixes/overlays on the City zoning map and in the Director’s records; ambiguous boundaries are resolved under § 19.16.050 and § 19.16.060. (§ 19.16.050; § 19.16.060).
• Review the permitted/conditional/excluded use list in Chapter 19.20 for residential and agricultural districts and the specific chapter for the base district (e.g., 19.28 for R‑1, 19.36 for R‑3). (§ 19.20.010; § 19.28.010; § 19.36.010).
• If your project needs parking calculations or layout, consult the City’s parking standards in Chapter 19.124 and plan accordingly; parking requirements are referenced repeatedly in district chapters (see e.g. § 19.32.060). Link: parking.
• Development standards (setbacks, heights, coverage) are in each district chapter — for typical single‑family design review/readiness consult the R‑1 chapter and the residential design review findings. Link: Development Standards.
• Many projects require a development permit or design review and the processing rules are in Chapters 19.12 and 19.156; check design review early.
• If your property has an overlay (for example the “i” one‑story overlay), confirm the overlay text — overlays modify base standards and are listed on the zoning map and in Title 19 (see the “i” suffix notes in the R‑1 and R‑2 rules). Link: overlay districts.
• Accessory Dwelling Units are governed both by Title 19 and state law; see the City ADU rules and state ADU law early in your review. Link: ADUs and California ADU law. If Title 19 is silent on a parcel‑specific allowance, "Not found in retrieved materials" applies — Verify with the jurisdiction.

Checklist (what an applicant must satisfy before submittal)

• Confirm the parcel base zone and any suffix/overlay on the zoning map (zoning map is adopted as part of Title 19; § 19.16.030).
• Check permitted/conditional/excluded uses in Chapter 19.20 and the specific zone chapter (e.g., 19.28, 19.32, 19.36, 19.38).
• Verify development standards (height, setbacks, lot coverage, FAR where applicable) in the applicable zone chapter and any combining district (e.g., TH) (§ 19.28, § 19.32, § 19.46).
• Prepare parking and loading that comply with Chapter 19.124 and any zone‑specific requirements. Link: parking.
• Confirm whether a development permit, conditional use permit, planned development approval, or design review is required (processing rules: Chapters 19.12, 19.152, 19.156).
• Identify specific plan or priority housing site status for the parcel (Priority Housing Sites are shown on the zoning map and can change as‑of‑right entitlements). (§ 19.80.030).
• If proposing ADUs or duplexes under state ministerial paths, check the City’s ministerial permit rules (e.g., § 19.28.150 for up to two units under Government Code § 65852.21). Link: ADUs and California ADU law.
• Confirm whether the parcel is subject to design standards, historic restrictions, signage or landscaping requirements — consult the applicable Title 19 chapters and links: Design Review, Historic Preservation, Signage, Landscaping and Screening.

Risks & Ambiguities

Plain‑English summary

Cupertino’s Title 19 sets a zoning map of base districts (e.g., R-1, R-2, R-3, R-4, CG, ML, P) and adopts district rules for permitted uses, heights, setbacks and coverage; the map and district chapters — not memory or third‑party summaries — control what you can build (see § 19.16.030 and each zone chapter).
