American Canyon — Zoning

Last reviewed: July 3, 2026

Overview

American Canyon's zoning is codified in Title 19 of the municipal code and establishes the city's base zoning districts, overlay zones, the official zoning map, permitted/conditional uses, and development standards. Use tables and district chapters identify what is allowed in each zone; the official zoning map administratively locates the districts (§ 19.03.010) . For on-site requirements consult the city's development standards and [parking] guidance; design-level approvals may require [design review] or discretionary permits depending on the district.

Below are district-by-district breakdowns based on the American Canyon Zoning Ordinance (Title 19). Each district entry gives the ordinance purpose, typical permitted uses, the most decision-relevant dimensional standards, and where the district is mapped. Always verify parcel-specific rules with the official map and the community development director (§ 19.03.010) .

RRH (Rural Residential — Hillside)

• Purpose: Provide for very low-density residential uses in peripheral foothill areas with special development controls for views and hillsides (§ 19.10.*) .
• Typical permitted uses: single‑family detached homes, large‑lot rural residences; accessory structures subject to special setbacks and height limits (§ 19.10.040; accessory rules at § 19.10.060) .

• Where it applies: As mapped on the official zoning map; uncertain boundaries follow map‑rules (§ 19.03.020) .

RR‑20000 and RR‑10000 (Rural Residential)

• Purpose: Very low‑density neighborhood patterns; distinguished by minimum lot sizes (§ 19.10.*) .
• Typical permitted uses: single‑family homes, limited accessory uses (mobile homes conditionally allowed in some RR districts) (§ 19.10.040) .
• Key standards: RR‑20000 = 20,000 sq ft minimum; RR‑10000 = 10,000 sq ft minimum; front/side/rear yard rules and lot width/depth standards in Table 19.10.050 (§ 19.10.050) .

RE (Estate Residential)

• Purpose: Large estate lots with extra setbacks and special provisions (e.g., Watson Lane/Paoli Loop special requirements) (§ 19.10.*) .
• Typical permitted uses and standards: Similar to RR with site‑specific design and airport‑compatibility review when applicable (§ 19.10.* and special requirements noted in the chapter) .

RS‑8000 and RS‑6500 (Suburban Residential)

• Purpose: Low‑density single‑family subdivisions; two separate RS districts by lot size (§ 19.10.*) .
• Typical permitted uses: detached single‑family housing, second units/ADUs subject to Section 19.10.120 and state ADU law (verify both local Section 19.10.120 and state rules) .

RO (Residential Overlay)

• Purpose: Overlay permitting high‑density multifamily on selected CN/CC parcels; 20 du/ac west of Broadway/Highway 29 and 35 du/ac east of Broadway/Highway 29; development must follow Chapter 19.11 multifamily/mixed‑use standards (§ 19.10.* and § 19.11.*) .
• Typical permitted uses: Multifamily residential and mixed‑use structures where mapped; specific uses and conditions in Table 1 of § 19.11.040 (§ 19.11.040) .

CC (Community Commercial) and CN (Neighborhood Commercial)

• Purpose: CC to serve the broader community; CN to serve day‑to‑day neighborhood needs (§ 19.11.020) .
• Typical permitted uses: Extensive retail, service, eating/drinking establishments, offices; multifamily allowed (see Table 1/§ 19.11.040) — cannabis indoor cultivation is listed as permitted in these districts subject to Chapter 5.10 (§ 19.11.040) .
• Key standards: Permitted/conditional uses in Table 1 (§ 19.11.040); dimensional development standards for commercial districts appear in Chapter 19.11 and related tables (§ 19.11.020–040) .

CS (Specialty Commercial Overlay)

• Purpose: Encourage visitor‑oriented, view‑capitalizing commercial uses on sites with unique views; overlays apply special development rules and use lists (§ 19.19.010–030) .
• Typical permitted uses: Visitor‑oriented retail, lodging, restaurants, public parking, utilities and public uses (detailed in § 19.19.020–030) .
• Key standards: Development standards for CS generally follow the LI schedule and include view‑oriented design criteria, pedestrian easement requirements, and airport‑compatibility measures when applicable (§ 19.19.030) .

PLI, LI, GI (Paoli Light Industrial, Light Industrial, General Industrial)

• Purpose: Provide for light and general industrial activities with tailored performance standards (noise, emissions, hazardous materials) (§ 19.14.010–040) .

Checklist

• Verify the parcel's zoning on the official zoning map (official map maintained by the community development director) (§ 19.03.010)
• Confirm whether the proposed use is a permitted (P), conditional (C), or minor (M) use in the district (see Table 19.10.040 for residential, Table 1/19.11.040 for commercial, and Table 19.14.050 for industrial) (§ 19.10.040; § 19.11.040; § 19.14.050)
• Confirm dimensional standards (lot area, setbacks, coverage, height) in the appropriate schedule (e.g., Table 19.10.050 for residential; Table 19.14.060 for industrial) (§ 19.10.050; § 19.14.060)
• Check overlay zones (RO, CS, Paoli, MHP‑S, airport compatibility notes) that may change allowed uses or require additional findings (§ 19.10.; § 19.19.; § 19.20.*; airport compatibility footnotes)
• Determine if discretionary review (use permit, planned community, specific plan, or design review) is required; see review rules and required findings for map/text amendments (§ 19.48.040; Chapter 19.40 referenced)
• For second units / ADUs consult local Section 19.10.120 and state ADU law; if in doubt consult the city planner and the city's ADU page ([American Canyon ADUs]) (§ 19.10.120)
• Confirm off‑street parking and loading standards in the city's [parking] chapter and calculate requirements based on the use (§ 19.14.070 and parking chapter references)

Risks & Ambiguities

Plain‑English Summary

American Canyon’s Title 19 divides the city into named zoning districts (for example, RS‑6500, RM, CN, LI, GI, and overlays like RO and CS) that control what you can build and where; the official zoning map tells you which district applies to your parcel (§ 19.03.010) . For any project you must check the permitted uses tables for that district, meet the district’s lot/setback/height rules (see the tables such as Table 19.10.050 and Table 19.14.060), and confirm if overlays or discretionary review will add extra conditions (§ 19.10.040; § 19.10.050; § 19.14.060; § 19.19.030) .
