Cotati — Zoning

Last reviewed: July 1, 2026

Overview

Cotati’s zoning is codified in the City’s Land Use Code (Title 17), which adopts a citywide zoning map and a set of districts that implement the General Plan. The code organizes zones as a rural→urban transect (from OSC and RR to TOC and downtown specific-plan districts) and includes several overlays and specific‑plan zones that add requirements on top of base districts. See the adoption of the zoning map and districts in § 17.20.020 and the purposes of the districts in § 17.20.030 .

How Cotati’s zoning is structured (quick guide)

• The official zoning map is adopted by reference and is on file with the Planning Department; boundary interpretation rules are in § 17.20.020 .
• Use permissions (what’s allowed and what permit is required) are listed in Tables 2‑2 and 2‑3 and implemented by § 17.22.020 .
• District-specific development standards (parcel size, setbacks, height, coverage) are summarized in Chapter 17.24 (see § 17.24.020 and § 17.24.030) .
• City‑wide design/site standards that apply in addition to district rules are in Chapter 17.30 (e.g., build‑to lines, setbacks, height exceptions) § 17.30.010–020 .
• Overlays and specific plans (for example CP, PF, MHP, SPD, SPSW) modify or add to the base rules; see Chapter 17.28 (for overlays and specific‑plan districts) § 17.28.010–070 .

For applicants: confirm the base zone on the adopted map, then read the applicable Tables 2‑2/2‑3 for allowable uses, then check the district development standards and Chapter 17.30 for site/design rules.

District-by-district breakdown

Below are Cotati’s primary zoning districts (as established in Table 2‑1) and the most decision‑relevant provisions the code shows. For each district I list purpose, typical permitted uses (high level), key dimensional controls that the code explicitly gives, and where the district typically applies. All required citations include the controlling section number.

Note: The city’s adopted zoning map locates these districts on specific parcels; always confirm parcel designation with the Planning Department (see § 17.20.020 ).

OSC (Open Space, Conservation)

• Purpose: preserve natural and scenic resources; limited development supporting conservation and caretaker quarters (§ 17.20.030 ).
• Typical uses: parks, conservation easements, caretaker housing (very limited residential) (§ 17.20.030 ).
• Key standards: Parcel and development standards are managed through subdivision review (see § 17.24.020 Table 2‑4) .
• Where applied: more rural edges and resource areas shown on the zoning map (§ 17.20.020 ).

OSR (Open Space, Recreation)

• Purpose: public parks and recreational uses; applied to publicly‑owned recreation lands (§ 17.20.030 ).
• Typical uses: parks, community recreation, cultural facilities.
• Key standards: Parcel size and development regulated through the subdivision/review process (Table 2‑4 / § 17.24.020) .

RR (Rural Residential)

• Purpose: agricultural and very low‑density residential (orchards, vineyards, grazing) (§ 17.20.030 ).
• Typical uses: agricultural operations, single‑family dwellings, accessory structures compatible with rural character.
• Key standards: Density ranges from 1 unit per 1.5 acres (RR‑1.5) to 1 unit per 1.0 acre (RR‑1.0) as shown in Table 2‑4 (§ 17.24.020) .

RVL (Residential Very Low Density)

• Purpose: larger‑lot detached single‑family neighborhoods (§ 17.20.030 ).
• Key standards: Densities shown as suffixes on the map (for example RVL‑0.66 = 1 unit per 0.66 acres; see § 17.24.020, Table 2‑4) .

NL (Neighborhood, Low Density)

• Purpose: low‑medium density residential (part of neighborhood transect) (Table 2‑1 / § 17.20.020) .
• Typical uses: detached single‑family, duplexes, limited accessory uses.
• Key dimensional standards (Table 2‑9 / § 17.24.030): front setback 20 ft., side interior 5 ft., street side 10 ft., rear 20 ft., garage setback 10 ft. from street‑facing façade; maximum site coverage 40%; building height 28 ft. for main structure .

NM (Neighborhood, Medium Density)

• Purpose: medium‑density residential (rowhouses, small multifamily) (Table 2‑1 / § 17.20.020) .
• Key dimensional standards (Table 2‑10 / § 17.24.030): front setback 15 ft., side interior typically 5 ft., street side 10 ft., rear 15 ft., garage 10 ft. back from façade; height and other standards vary with building type (see § 17.24.030) .

NU (Neighborhood, Urban)

• Purpose: higher‑density residential urban form with mixed housing types (Table 2‑1) .
• Standards: Table references and illustrations in Chapter 17.24 apply; specific numeric setbacks and heights for NU are defined in Table 2‑4 / 2‑? and in Chapter 17.24 — consult those tables for parcel‑level values (§ 17.24.020, § 17.24.030) . If a numeric is critical for your parcel, verify with Planning — some NU specifics were not visible in retrieved excerpts.

CE (East Cotati Avenue Corridor) and CG (Gravenstein Highway Corridor)

• Purpose: corridor commercial/auto‑oriented uses and general highway commercial (Table 2‑1 / § 17.20.020) .
• Typical uses: retail, service stations, restaurants (some formula‑fast‑food limits apply by district; see § 17.42.071) .
• Key constraints: some specialized uses (e.g., formula fast food) require use permits and are subject to citywide caps by district § 17.42.071 .

CA (Commerce Avenue / Downtown specific plan areas: CA, CD, HC, LP, NG, SWSP)

• Purpose: downtown and specific‑plan areas (Commerce Avenue district is part of the Downtown Specific Plan; CA implements downtown general plan designations) § 17.20.030 and specific‑plan sections § 17.28.050 and § 17.28.060 .
• Typical uses: pedestrian‑oriented retail, office, mixed residential up to 12 units per acre in some Commerce Avenue areas; downtown specific plans supply detailed allowable uses and development standards (see § 17.28.050 and the downtown specific plan attachments) .
• Key process note: the SPD and SPSW districts rely on the applicable specific plan for many standards (see § 17.28.050 and § 17.28.060) .

TOC (Transit Oriented Community / Transit Oriented District)

• Purpose: higher‑intensity mixed‑use and multifamily adjacent to transit (Table 2‑1) — implements mixed commercial/residential and Santero Way specific plan elements § 17.20.020 .
• Standards: listed in Table 2‑1 and governed by specific plan standards where applicable — verify parcel‑level rules (see § 17.24.020 and applicable specific plan sections) .

CI (Commercial/Industrial)

• Purpose: industrial and light industrial uses and commercial‑industrial transition areas (Table 2‑1) .
• Typical uses: manufacturing, warehouses, business parks; development standards are in Chapter 17.24 and Chapter 17.26 for industrial street/streetscape standards (§ 17.24.030, § 17.26.030–040) .

Overlay & Special Purpose districts (summary)

• CP (Coordinated Planning overlay): requires a master plan and pauses certain building/permit approvals until an approved master plan is in place; mapping is by suffix on the zoning map and applied by rezoning (§ 17.28.020) .
• MHP / MHP‑S (Mobilehome Park / Senior Mobilehome Park overlays), PF (Public Facility), PUD (existing Planned Unit Developments): each adds or restricts uses; PUDs are treated as overlays where new PUDs are not permitted, but existing PUDs remain under their original ordinance or may default to the underlying district standards (§ 17.28.070) .
• For full overlay rules see Chapter 17.28 (§ 17.28.010–070) .

Key decision‑relevant standards (quick lookup table)

(For full numeric tables — Table 2‑4, Tables 2‑9/2‑10 — see Chapter 17.24; the code includes figures for building placement and height profiles) § 17.24.020–030 .

Practical guidance and how rules interact

• Start with the adopted zoning map to confirm your parcel’s exact zone designation (§ 17.20.020) .
• Check the allowable‑uses tables (Tables 2‑2/2‑3) to identify whether the use is allowed outright, needs a minor use permit, conditional use permit, or is prohibited (§ 17.22.020) .
• After use permission is confirmed, apply the district development standards in Chapter 17.24 (parcel size, density, setbacks, height) and then Chapter 17.30 (site/design details like build‑to line exceptions, setbacks, fences) § 17.24.020–030; § 17.30.010–020 .
• Overlays or a specific plan (for example CP, SPD, SPSW) may require a master plan or refer you to a different set of standards; these overlays are added by suffix on the zoning map and will alter permit timelines (§ 17.28.020; § 17.28.050–060) .
• Some commercial uses (for example formula‑based fast food) are limited by caps per district — check special use standards in Article 4 (example § 17.42.071) .
• Design and site review requirements and parking standards are separate but interlocking: check the city’s Cotati Design Review rules and Cotati Parking guidance early in project scoping (design review wording not fully visible in retrieved excerpts; verify with staff) Not found in retrieved materials for the exact design‑review code section.

Helpful links as you read the code: the city’s Cotati Land Use summary; the Cotati Development Standards and the Cotati Overlay Districts pages explain how the specific plans and overlays are applied in practice. If you’re considering accessory dwelling units, consult the city’s Cotati ADUs page and the California ADU law; building permits must still comply with the California Building Standards Code.

Information Gaps (things not confirmed in the retrieved excerpts)

• Exact numeric setback and height tables for NU, CD, HC, LP, and some downtown plan subzones were not fully visible in retrieved excerpts — verify the parcel‑level tables in Chapter 17.24 or the downtown specific plan attachments (§ 17.24.020–030).
• The specific code section for Cotati’s design‑review thresholds and procedures is not present in the excerpts I reviewed. "Design review" link provided above is internal guidance; the controlling § is Not found in retrieved materials — verify with Planning.
• Full contents of Tables 2‑2 and 2‑3 (the complete allowable‑uses matrices) were referenced but not provided verbatim in the excerpts; consult Chapter 17.22 directly (§ 17.22.020) for parcel‑specific use permissions.

Checklist (what an applicant must satisfy)

• Confirm parcel zone on the official zoning map (adopted by reference) § 17.20.020 .
• Verify the proposed use is listed and identify required planning permit in Tables 2‑2/2‑3 § 17.22.020 .
• Apply district development standards (parcel size/density, setbacks, height, coverage) from Chapter 17.24 § 17.24.020–030 .
• Comply with Chapter 17.30 site and design standards (setback exceptions, build‑to lines, screening, height exceptions) § 17.30.010–020 .
• Check overlays / specific plans that apply to the parcel (CP, SPD, SPSW, PUD) and satisfy master‑plan or specific‑plan prerequisites § 17.28.010–070 .
• If commercial, confirm any special use standards (caps, performance standards) such as formula‑fast‑food rules § 17.42.071 .
• Early check for parking and site circulation requirements via the city’s Cotati Parking guidance and Chapter 17.26 street/streetscape standards § 17.26.030–040 .
• If proposing an ADU, follow Cotati ADU guidance and California ADU law; final building work must comply with the California Building Standards Code (Title 24). § references for ADU code sections: Not found in retrieved materials (verify with city/ADU page).

Risks & Ambiguities

Plain-English Summary

Cotati organizes land into a clear set of base zones (from rural open space to high‑density/transit zones) with an official zoning map; what you can build depends first on the zone and Tables 2‑2/2‑3, then on district development standards and citywide site/design rules — overlays and specific plans can change the game and sometimes require a master plan § 17.20.020; § 17.22.020; § 17.24.020; § 17.28.020 .
