Last reviewed: July 1, 2026

Overview

Calistoga's zoning rules are codified in Title 17 of the Calistoga Municipal Code. The code divides the city into named base districts (for example RR, R-1, R-2, DC, CC, PD, I) and a set of combining districts; the official Zoning Map that locates these districts is adopted by reference and is on file with the City Clerk (§ 17.03.010) . General map rules and how map boundaries are interpreted are set out in § 17.03.020 and the base district list appears in § 17.03.040 . Where the code refers to numeric development limits (setbacks, height, lot coverage), those are the controlling standards for each district (see district subsections below) — applicants should also review the city's development standards and parking rules as they commonly apply to zoning approvals.

Below is a district-by-district synthesis of what the Calistoga zoning ordinance actually says. For each named district I summarize the purpose, the typical permitted uses, the most decision-relevant dimensional standards, and where the district is located/applied (per the adopted map). I cite the controlling Code § for each statement; for full ordinance text consult the cited §.

RR — Rural Residential (Chapter 17.14 CMC)

  • Purpose: The RR district is intended to allow single‑family residences on large lots and to act as a buffer between agricultural lands and urban Calistoga (§ 17.14.010) .
  • Typical permitted uses: One single‑family dwelling per lot, one accessory dwelling unit (see Chapter 17.37), light agricultural uses (vineyards, horticulture), supportive/transitional housing, and residential care for up to 12 persons (§ 17.14.020) .
  • Key dimensional standards:
    • Minimum lot area: variable depending on utilities (e.g., 80,000 sq ft with on‑site water and wastewater; 20,000 sq ft if city water/wastewater) (§ 17.14.030) .
    • Setbacks: Front 20 ft, interior side 10 ft (20 ft for nonresidential), corner/street side 15–20 ft, rear 20 ft (§ 17.14.040) .
    • Lot coverage: 30% max; maximum height 25 ft (§ 17.14.040) .
  • Where it applies: As shown on the adopted Zoning Map; see § 17.03.010 and map on file with the City Clerk (§ 17.03.010) .

RR‑H — Rural Residential – Hillside (Chapter 17.15 CMC)

  • Purpose: Preserve environmental and scenic hillside characteristics, protect natural topography, and manage hillside hazards; development must follow the hillside principles listed in § 17.15.010 .
  • Typical permitted uses: Similar residential and accessory uses to RR but subject to hillside-specific development principles (detailed in § 17.15.010). Specific allowed uses and development standards are set in Chapter 17.15 .
  • Key dimensional/plan standards: The chapter emphasizes design that minimizes cut/fill, preserves views, and may allow exceptions to street standards to preserve natural features (§ 17.15.010) .
  • Where it applies: Hillside parcels identified on the official Zoning Map (§ 17.03.010) .

R‑1 and R‑1‑10 — One‑Family Residential (Chapter 17.16 CMC)

  • Purpose: Single‑family residential neighborhoods consistent with General Plan goals (§ 17.16 chapters) .
  • Typical permitted uses: One single‑family dwelling per lot, accessory dwelling units (per Chapter 17.37), junior accessory dwelling units (§ 17.16 references) .
  • Key dimensional standards (applies across R‑1 and R‑1‑10, with larger minimum lot dimensions for R‑1‑10):
    • Front setback: 20 ft (§ 17.16.040(A)(1)) .
    • Side yards: minimum generally one‑half the building height, with minimums of 5 ft for small buildings and max interior side 15 ft; street side 15–20 ft (§ 17.16.040(A)(2)) .
    • Rear yard: 20 ft (§ 17.16.040(A)(3)) .
    • Lot coverage: 50% for lots ≤7,200 sq ft; 40% for larger lots; 35% for >10,000 sq ft in R‑1‑10; accessory structures/ADUs have special coverage exceptions (§ 17.16.040(C)) .
    • Max building height for primary dwellings: 25 ft (§ 17.16.040(D)) .
  • Other requirements: design review, affordable housing rules, off‑street parking, and general exceptions also apply (§ 17.16.050) .

R‑2 — Two‑Family Residential (Chapter 17.18 CMC)

  • Purpose: Allows single‑family, duplex and certain special‑needs housing while preserving private open space (§ 17.18.010) .
  • Typical permitted uses: One one‑family dwelling per lot; one accessory dwelling unit on a lot with a single‑family dwelling (per Chapter 17.37); duplexes or two one‑family dwellings on lots ≥ 9,000 sq ft; supportive and transitional housing; small residential care homes (§ 17.18.020) .
  • Dimensional standards and other development rules: Specific development standards are in Chapter 17.18 and general provisions (design review, parking, use permits) apply (see § 17.18 and cross‑references) .

R‑3 — Multifamily Residential/Office (Chapter 17.19 CMC)

  • Purpose, uses and standards: The base district R‑3 is established in § 17.03.040 as a base district; detailed provisions are in Chapter 17.19. Detailed text for R‑3 was Not found in retrieved materials; consult Chapter 17.19 of Title 17 for the full list of permitted uses and standards (§ 17.03.040) .

MHP — Mobile Home Park (Chapter 17.20 CMC)

  • Purpose, permitted uses, and standards: Identified as a base district in § 17.03.040, but chapter text for MHP (Chapter 17.20) was Not found in retrieved materials — verify with the City’s Title 17 text or the specific chapter for mobile home park standards (§ 17.03.040) .

DC — Downtown Commercial (Chapter 17.21 CMC)

  • Purpose and uses: Listed as a base commercial district in § 17.03.040; the detailed allowed uses and development standards for DC are located in Chapter 17.21 (detailed chapter content Not found in retrieved materials) (§ 17.03.040) .

CC — Community Commercial (Chapter 17.22 CMC)

  • Purpose and uses: Listed in § 17.03.040; detailed allowances and standards are in Chapter 17.22 (detailed chapter content Not found in retrieved materials) (§ 17.03.040) .

P — Public (Chapter 17.23 CMC)

  • Purpose and uses: Identified as a base district in § 17.03.040. Specific permitted public uses and standards are in Chapter 17.23 (detailed chapter content Not found in retrieved materials) (§ 17.03.040) .

PD — Planned Development (Chapter 17.24 CMC)

  • Purpose and overall approach: PD is intended to allow coordinated, often mixed‑use developments that conform to the General Plan and that may depart from strict application of base district standards when justified (§ 17.24.010–17.24.040) .
  • How PD works:
    • A PD may be a base district (designated PD + number) or a combining district (PD appended to a base zone) (§ 17.24.020) .
    • In a PD combining district, uses normally permitted by the base district apply; in a PD base district uses are tied to the General Plan and the adopted PD development plan (§ 17.24.030) .
    • The Planning Commission and City Council may allow variations from standard zoning development standards for PDs (height, lot coverage, parking, setbacks) when supported in the development plan (§ 17.24.040) .
  • Application and review: PD applications must include a detailed development plan, and approval is subject to findings including General Plan consistency (§ 17.24.050–17.24.060) .

I — Light Industrial (Chapter 17.26 CMC)

  • Purpose and uses: Listed as a base district in § 17.03.040; detailed permitted industrial uses and standards are in Chapter 17.26 (detailed chapter content Not found in retrieved materials) (§ 17.03.040) .

Combining districts and special designations

  • The code establishes several combining districts such as PD, DD (Design District), A (Airport), and VA (Visitor Accommodations); the list is in § 17.03.050 and each combining district chapter contains how it attaches to base zones and any special rules (§ 17.03.050) .
  • Planned Development chapters for named PDs (e.g., PD 2010‑01, PD 2002‑2, PD 2012‑01) contain parcel‑specific uses and standards (example: PD 2002‑2 Maxfield, PD 2012‑01 Berry Cottages) — those are individually codified in Chapter 17.24 articles (§ 17.24.120 onwards) .

Key standards at a glance

PD (general) PD can vary base standards (height, coverage, parking, setbacks) when supported in development plan § 17.24.020–040
Map rules Zoning map adopted by reference; boundary rules for uncertain lines (map scale, property lines, vacated streets) § 17.03.010–020

Notes: many district chapters reference other Title 17 chapters (for example, design review in Chapter 17.06, parking in Chapter 17.36, ADU rules in Chapter 17.37). For design guidance see the city's design review page and for ADUs see Calistoga ADUs. Also remember that building construction standards fall under the California Building Standards Code, not Title 17.

Checklist

  • Confirm the parcel's base and any combining/overlay districts on the City’s adopted Zoning Map (§ 17.03.010) .
  • Verify permitted uses for that district (consult the applicable chapter: e.g., 17.14 for RR, 17.16 for R‑1, 17.18 for R‑2) and any use‑permit triggers (§ 17.03.040) .
  • Check dimensional standards: minimum lot area, setbacks, lot coverage, and height in the district chapter (examples: § 17.14.030–040, § 17.16.040) .
  • Review whether design review (Chapter 17.06) or a PD development plan applies and prepare required materials; consult the design review guidance.
  • Confirm on‑site parking obligations per Chapter 17.36 and the City’s parking standards.
  • If proposing an ADU, consult Chapter 17.37 and the city's ADU policy page (Calistoga ADUs); confirm any local exceptions.
  • If a combining district or PD is proposed, prepare a PD development plan and the application contents required in § 17.24.050 .
  • For map boundary uncertainty (lot splits, boundaries that bisect parcels) follow rules in § 17.03.020 and consider rezoning/clarification if ownership spans districts (§ 17.03.020(E)) .

Risks & Ambiguities

Issue Why it matters What to verify
Zoning map boundary ambiguity Map scale or lines that "follow street lines" may create uncertainty about which district a parcel is in (§ 17.03.020) Verify the City Clerk's official Zoning Map and the map scale; ask the Planning Department for an interpreted map or boundary determination (§ 17.03.010–020)
Uses not expressly listed The code allows the Planning Commission to deem unlisted uses "similar" — meaning an intended use may require a Commission determination and findings (§ 17.03.090) If a use is not listed, submit a description and expect the Commission to evaluate compatibility per § 17.03.090
PD deviations from base standards PDs can modify height/coverage/parking and become the governing standards; this can change what is allowed on a site (§ 17.24.040) For PDs, get the adopted PD development plan and ordinance language; verify whether your parcel is inside a PD with record conditions (§ 17.24.120+)
ADU local specifics Title 17 repeatedly references Chapter 17.37 for ADU rules but that chapter text was Not found in retrieved materials Consult Chapter 17.37 and the city's ADU resource page (Calistoga ADUs); verify local ADU setbacks, coverage exceptions, and ministerial allowances
Parcel‑specific standards (PDs and special PD articles) Some PDs (for example PD 2010‑01, PD 2012‑01) contain parcel‑specific lot sizes and setbacks that override base rules (§ 17.24 articles) Confirm whether your parcel lies within a site‑specific PD and which PD article applies; read the PD's development standards in Chapter 17.24

Plain‑English Summary

Calistoga’s zoning (Title 17) assigns every parcel to a named zoning district on the official Zoning Map; each district chapter (for example RR § 17.14, R‑1 § 17.16, R‑2 § 17.18, PD § 17.24) sets the allowed uses, setbacks, lot coverage and height rules that control what you can build — consult the specific chapter for the numeric standards and reference the adopted Zoning Map to see which district(s) apply to your property (§ 17.03.010–040) .

Frequently asked questions

What can I build on an R-1 lot in Calistoga?

In R‑1 or R‑1‑10 you can build one principal single‑family dwelling per lot and permitted accessory uses; one accessory dwelling unit is allowed per the ADU chapter, and setbacks are generally Front 20 ft, side yards tied to building height (minimum 5 ft in some cases), rear 20 ft, with maximum primary dwelling height 25 ft (§ 17.16.040) .

What are Calistoga setback requirements for single‑family homes?

Setbacks vary by district. In R‑1/R‑1‑10 the code lists Front 20 ft, side yards typically half the building height (min 5 ft), and Rear 20 ft; in RR fronts and rears are 20 ft with interior side 10 ft (20 ft for nonresidential) — see § 17.16.040 and § 17.14.040 for details and exceptions .

Do I need design review for my project in Calistoga?

Many districts require design review; district chapters (for example RR, R‑1) cross‑reference Chapter 17.06 for design review requirements. Where design review is required it will be explicitly stated in the district chapter (e.g., § 17.14.050, § 17.16.050) . See the city's design review guidance.

Where do I find the official zoning map and how are boundaries interpreted?

The official Zoning Map is adopted by reference and is on file with the City Clerk per § 17.03.010; where boundaries are ambiguous the rules in § 17.03.020 (follow property/street lines, use map scale, etc.) apply (§ 17.03.010–020) .

Can a Planned Development (PD) change setback or height limits for my site?

Yes. A PD can allow or require variations from the base district's development standards (height, lot coverage, parking, setbacks) when approved in the PD development plan; see § 17.24.040 and the adopted PD article that covers the parcel for the binding rules (§ 17.24.040) .

What if my proposed use is not listed in the zoning chapter?

Title 17 allows the Planning Commission to determine that an unlisted use is "similar" to listed uses; the Commission must make findings about consistency with district purpose and compatibility (§ 17.03.090) .

Are ADU rules in Title 17 — and where are they?

Title 17 references accessory dwelling units (ADUs) repeatedly and points to Chapter 17.37 for ADU specifics; the district chapters note ADU availability but the full ADU standards are in 17.37 (consult that chapter and the city's ADU guidance page for the exact municipal requirements) (§ 17.16, § 17.14 references to Chapter 17.37) .

If a district chapter and the zoning map conflict, which controls?

The zoning map and the district regulations are adopted together; map designations and the district regulations apply to the lands within the map boundaries. Map‑boundary interpretation rules are in § 17.03.020 and general compliance is required by § 17.03.080 .
