Mono County — Zoning

Last reviewed: July 3, 2026

Overview

This page summarizes how zoning (land use designations and associated standards) works in the unincorporated areas of Mono County under the County's Land Development Regulations and Land Use Element. Mono County uses permissive zoning: each parcel has a land use designation on the County land-use maps and only the uses and standards listed for that designation are allowed unless an explicit approval (Director Review, Use Permit, variance) applies. See the application/scope rules in § 01.030 and the permissive-zoning rule in § 01.040 for the legal basis.

NOTE: everything below applies only to the unincorporated areas of Mono County (the County code and maps), not to incorporated towns which have their own codes. Verify parcel-specific rules with the County. See where your parcel is designated on the County map as required by § 01.060.

How the code is organized (what to read first)

• The Land Development Regulations list land use designations and identify that the summary sheets appear in Section IV; see § 03.020 for the list of designations and where the district summaries live.
• General development rules (lot area, yards, height, uses permitted, Director Review/Use Permit procedures) are in Chapter 04; see especially § 04.020 (uses), § 04.080 (lot area), § 04.110 (height), and § 04.120 (yards/setbacks).
• Specific programs (Accessory Dwelling Units, parking, signs, cannabis, mobile-home park standards, etc.) live in the chapters called out in the district sheets (for example Ch. 16 for ADUs, Ch. 06 for parking, Ch. 07 for signs, Ch. 13 for cannabis). Link references to the County's topic pages are provided below where helpful.

(First mention links: development standards, parking, design review, overlay districts, ADUs, Title 24, signage.)

• Mono County Development Standards (general rules)
• Off-street parking rules are in Chapter 06 and are cross-referenced from district sheets.
• Design review and Site Plan Review are implemented via Chapter 09 and Chapter 04 site-plan rules.
• Overlay districts such as the Scenic Combining (S‑C) district supplement base districts (see Chapter 08).
• Accessory Dwelling Units must follow state rules and Mono County's ADU rules (see Ch. 16 and the State ADU law) — see California ADU law.
• Building permits remain subject to the California Building Standards Code (Title 24) even when a land-use approval is granted.

District-by-district breakdown (key districts used in Mono County)

Below are the frequently used land use designations shown on the Mono County land-use maps. For each I give the intent, typical permitted uses, and the decision-relevant numeric standards cited to the Land Development Regulations and Land Use Element.

Notes on citing: the formal list of land use designations is recorded in § 03.020; the per‑designation development summaries appear in Section IV of the Land Use Element and are cross‑referenced by the Land Development Regulations (see § 03.020 and the district summary pages).

Rural Residential (RR)

• Purpose: permit larger-lot single‑family dwellings and ancillary rural uses away from community centers.
• Typical permitted uses: single‑family dwelling, small‑scale agriculture, accessory buildings, home occupations, manufactured homes as dwellings, Accessory Dwelling Units (subject to ADU rules).
• Key numeric standards:
  • Minimum parcel size: 1 acre (areas lacking sewer/water may have different minima) — see district sheet and § 04.080.
  • Setbacks (Table 04.120): Front 50' / Rear 30' / Side 30' for parcels >1 acre; Front 50' / Rear 10' / Side 10' for parcels <1 acre — § 04.120.
  • Max building height: typically 35' (see § 04.110 / Table 04.010).
• Where it applies: see the land-use maps (Section IV / § 03.020).

Estate Residential (ER)

• Purpose: larger‑lot single‑family lots near developed communities; allows small‑scale agriculture.
• Typical permitted uses: single‑family dwelling, accessory buildings, manufactured home used as a dwelling, ADUs, home occupations.
• Key numeric standards:
  • Minimum parcel size: commonly 1 acre (see district sheet).
  • Setbacks: ER <1 acre — Front 50' / Rear 10' / Side 10'**; **ER >1 acre — Front 50' / Rear 30' / Side 30' per § 04.120.
  • Max height: 35' (Table 04.010 / § 04.110).

Rural Mobile Home (RMH)

  • Setbacks (Table 04.120): RMH <1 acre — Front 20' / Rear 10' / Side 10'**; **RMH >1 acre — 30'/30'/30'. § 04.120.
  • Maximum lot coverage: 40% (district sheet).

  • Site disturbance limit: 10% (includes max 5% lot coverage unless offset by permanent open space).

Commercial (C) and Commercial Lodging (CL‑M, CL‑H)

• Purpose: C is general commercial; CL‑M/CL‑H are commercial lodging designations for visitor lodging (moderate / high intensity).
• Typical permitted uses (C): change‑of‑use in existing conforming structures for retail, services, professional offices; many new commercial uses require Director Review or Use Permit.
• Typical permitted uses (CL‑M / CL‑H): lodging, multifamily housing in community areas; larger lodging projects require Use Permit.

(For complete numeric detail consult the district summary sheet and Table 04.120: Minimum Yards and Table 04.010: Building Heights.)

How approvals work — Director Review, Use Permits, Variances

• Uses not listed as permitted are presumed prohibited unless allowed by Director Review or Use Permit per § 04.030, § 04.040, and § 04.050; the district summary sheets list which uses are allowed outright, which require Director Review, and which require a Use Permit.
• A Minor Variance (up to a 10% relaxation of a single standard) may be granted by the Director under § 01.041 if specific findings are met.
• Design Review or Site Plan Review requirements are cross‑referenced in Chapter 04 and Chapter 09; projects subject to use permit often must submit landscaping, parking, and design materials. See § 04.210 and § 04.260.

Checklist (what an applicant must satisfy for a typical project in unincorporated Mono County)

• Confirm the parcel's land use designation on the County land‑use map (§ 01.060, § 03.020) and read the district summary.
• Confirm the proposed use is listed as permitted, Director‑review, or Use‑permit in the district sheet (§ 04.020).
• Check numeric standards: lot area (§ 04.080), setbacks (§ 04.120), height (§ 04.110), lot coverage and site‑disturbance limits (district sheet).
• Confirm parking requirements (Chapter 06 / parking) and provide parking calculations.
• Determine if Design Review or Site Plan Review applies and prepare design materials (Design Review).
• If proposing an ADU, confirm compliance with County ADU standards and state ADU law (California ADU law).
• If proposing cannabis, lodging, mobile‑home park, RV park, or other special uses, read the specialty chapters (e.g., Ch. 13 Cannabis, Ch. 17 Mobile Homes).
• Confirm any overlay or scenic combining district restrictions (Overlay Districts; Chapter 08).
• Check for fire‑safety setbacks and CalFire requirements referenced in § 04.120 and related Fire Safe Regulations.
• Prepare environmental review materials (CEQA) where required per § 04.240.

Risks & Ambiguities

Plain‑English summary

Mono County assigns every unincorporated parcel a land‑use designation (RR, ER, RU, C, IP, etc.). Only the uses listed in that designation are allowed unless you apply for Director Review or a Use Permit; setbacks, lot size, lot coverage, and height are set by district tables (not general city rules). Check the County land‑use map first, then the district sheet and the development‑standards tables (yards, height, parking) before you design a project. See § 03.020, § 04.120, and § 04.110 for the controlling rules.
