Mono County Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

This page orients readers to land use, zoning and development regulation for the unincorporated areas of Mono County (the County’s Land Development Regulations that implement the General Plan). The County’s rules are organized as a set of Land Development Regulations (the General Plan’s Land Use Element and implementing chapters that the County uses to regulate development in unincorporated Mono County) and are applied to parcels outside incorporated cities. The regulations establish the County’s land‑use designations, development standards (setbacks, height, lot coverage, parking), permit paths (Director review, Use Permits, Variances), overlay/special districts, and special chapters (ADUs, fire‑safe rules, short‑term rentals, commercial cannabis, etc.). See the County’s base zoning inventory at Mono County Zoning and the implementing rules at Mono County Land Use. § 01.010, § 01.020, § 01.030 .

How Mono County's code is organized

• Official name / placement: the County implements land use through its Land Development Regulations as part of the General Plan (VI. Land Development Regulations). The implementing regulatory chapters are identified in the Land Use Element and deployed as the County’s development regulations (the General Plan Land Development Regulations / Mono County Code implementation); the Specific Plan chapter cross‑references the Mono County Code (Title 17) for the “Land Project” definition, indicating the code is implemented within Mono County’s code framework (see § 36.020). § 36.020, § 01.020 .
• Table of parts: the Land Development Regulations arrange material by chapter (e.g., Chapter 01 – Introductory Provisions; Chapter 04 – Development Standards (General); Chapter 06 – Parking; Chapter 07 – Signs; Chapter 09 – Design Review District; Chapter 16 – Accessory Dwelling Units; Chapter 22 – Fire Safe Regulations; Chapter 30–39 – Processing; Chapter 36 – Specific Plans; and procedure chapters such as Chapter 46–49). See the Land Development Regulations table of contents for the chapter list. § 01.010; Ch. 04; Ch. 06; Ch. 16; Ch. 36; Ch. 22; Ch. 31–32 .

Practical navigation:

• Read § 01.030 for the code’s scope (applies to unincorporated County lands) and § 01.020 for the County’s authority to regulate land use. § 01.030, § 01.020 .
• For district rules (permitted uses, densities, setbacks, heights) consult each land‑use designation entry in the Land Use Element (e.g., SFR, RR, AG, C, IP, I, MFR-L/M/M-H, RU, RMH) — each designation entry shows permitted uses and the controlling development‑standard references (see examples below). Ch. 03; § 01.060 .

Zoning district families (what the County actually uses)

Mono County uses land‑use designations (districts) rather than a single alphanumeric “R‑1/C‑2” municipal table. Key district families (names used in the Land Use Element and Land Development Regulations) include:

• Single‑Family Residential (SFR) — example controlling standards: Minimum lot 7,500 sf, Maximum lot coverage 40%, Front setback 20 ft, Rear 10 ft, Side 10 ft, Maximum building height 35 ft; ADUs permitted per Chapter 16. SFR permitted uses and standards are listed in the SFR entry. See § 01.060; SFR entry (development standards). § 01.060; SFR development standards .

• Rural Residential (RR) and Estate Residential (ER) — larger minimum parcel sizes, larger setbacks (examples: Front 50 ft, Rear 30 ft, Side 30 ft, Max height 35 ft for many rural residential designations). RR/ER entries list specific minimum parcel and setback rules. See RR / ER development standards. RR / ER entry § 01.060 .

• Agriculture (AG) — agricultural uses prioritized; development credits and clustering rules apply; AG entries allow ADUs per Chapter 16 and include special development‑credit provisions. See §§ 12.030–12.040 (Development Credits) and AG designation. § 12.030, § 12.040 .

• Commercial (C), Commercial‑Lodging (CL‑M/CL‑H) and Mixed Use (MU) — commercial/mixed‑use districts include lower setbacks (e.g., front 10 ft, rear 5 ft) and higher lot coverage allowances (e.g., 60–70% depending on designation) and specific density rules for lodging vs residential. See the Commercial and CL entries and Table 04.010 references for heights. C / CL entries; Table 04.010 .

• Multi‑Family Residential (MFR‑L / MFR‑M / MFR‑H) — three multi‑family classes with different density caps (examples: MFR‑M / MFR‑H up to 15 du/acre, MFR‑H allows lodging and higher intensities); setbacks and coverage vary by tier. MFR entries provide specific unit/lot formulas. MFR entries; Table 04.010 .

• Industrial Park (IP) and Industrial (I) — IP for light/moderate industry (max coverage 80%, height 40 ft), I for heavier industrial uses and remote siting; caretaker unit allowances and specific setback rules are included. IP / I entries. IP/I entries § 01.060; Table 04.010 .

• Special and overlay districts: Scenic Combining / State Scenic Highway, Design Review District, Equestrian Overlay District, Fire Safe Regulations (Ch. 22), Dark Sky Regulations (Ch. 23), and area‑specific policies (e.g., June Lake policies). See Ch. 08, Ch. 09, Ch. 10, Ch. 22 and Ch. 23 for overlay rules and special standards. Ch. 08; Ch. 09; Ch. 10; Ch. 22; Ch. 23 .

(Where the Land Use Element lists a designation it also cross‑references the implementing chapters for parking, signs, design review, ADUs, etc.; see list in the Land Development Regulations table of contents.) Ch. 04; Ch. 06; Ch. 07; Ch. 16 .

Citywide development standards (high‑level)

• Organization: basic development standards are set in Chapter 04 – Development Standards (General) and by the individual land‑use designation entries (which show minimum parcel sizes, minimum district area, setbacks, maximum lot coverage, densities and building heights). See Ch. 04 and the land use entries (e.g., SFR, C, IP). Ch. 04; SFR entry; C entry .

• Setbacks, heights, lot coverage:

  • Setbacks: each land‑use designation lists minimum setbacks (examples: SFR front 20 ft / rear 10 ft / side 10 ft; commercial front 10 ft / rear 5 ft / side 0–10 ft; many rural designations use 50/30/30 ft) — see the individual designation entries for the controlling numbers and consult § 04.120 for other yard provisions. SFR entry; C entry; RR/ER entries; see § 04.120. § 04.120 .
  • Heights: the County uses a building‑height table (Table 04.010) referenced in each designation; many residential districts show maximum building height 35 ft, industrial 40 ft (with Director authority to exceed in some cases). Table 04.010; designation entries. Table 04.010; IP/I entries .
  • Lot coverage / density: each designation specifies maximum lot coverage and units per acre (examples above). See the designation entries for exact coverage and density caps. C / MFR / SFR entries .

• Parking: parking standards are collected in Chapter 06 – Parking; many land‑use entries refer to Ch. 06 for required parking ratios or site‑specific parking plans (e.g., commercial cannabis, lodging and mixed‑use entries require a parking plan that comply with Chapter 6). See Ch. 06 and chapter cross‑references in individual land use entries. Chapter 06; example parking cross‑reference. Ch. 06; commercial cannabis parking requirements .

• Design & discretionary review: design and discretionary controls are handled through Chapter 09 – Design Review District, and through the County’s processing chapters: Chapter 31 – Director Review, Chapter 32 – Use Permit, Chapter 33 – Variance, Chapter 34 – Nonconforming Uses. A number of entries list uses that are permitted only subject to Director Review or Use Permit. See Ch. 09; Ch. 31; Ch. 32; Ch. 33; Ch. 34. Ch. 09; Chs. 31–34 .

• Special technical standards: fire safety is enforced via Chapter 22 – Fire Safe Regulations and applies to building permits, parcel creation and other development actions in State Responsibility Areas; dark‑sky and defensible‑space rules appear in Ch. 23 and Ch. 22 respectively and can be conditions of permit approvals. See § 22.010–22.030 and Ch. 23. § 22.010; § 22.030; Ch. 23 .

• Topic‑specific standards: the Land Development Regulations include chapters for Accessory Dwelling Units (Ch. 16), Commercial Cannabis (Ch. 13), Short‑Term Rentals (Ch. 25), Flood plain (Ch. 21), Mobile‑home parks (Ch. 17) and more; each chapter contains use‑specific rules and submittal requirements. See Ch. 13; Ch. 16; Ch. 25; Ch. 17. Ch. 13; Ch. 16; Ch. 25; Ch. 17 .

Specific plans & overlays

• Specific plans: Mono County’s specific‑plan process is codified in § 36.010–36.060 (Chapter 36). A Specific Plan is an implementing device for the General Plan and can substitute for other development regulations where adopted; the Chapter describes required contents (text, maps), CEQA treatment and when a specific plan is required (e.g., large “land projects” and certain subdivisions). § 36.010; § 36.030; § 36.040 .
• Overlays and combining districts: the Land Development Regulations include overlay/combining districts such as the Scenic Combining District / State Scenic Highway (Ch. 08), Design Review District (Ch. 09), Equestrian Overlay District (Ch. 10) and area plans with area‑specific policies (e.g., June Lake, Antelope Valley). These overlays impose additional standards or review steps (landscape, viewshed, materials). Ch. 08; Ch. 09; Ch. 10; June Lake policies .

Building permits & review (typical path for a project)

• Initial scope: the Land Development Regulations apply to land in the unincorporated area for all land uses and to most development permits; § 01.030 states the regulations apply to unincorporated County lands and that development must be consistent with those regulations and the General Plan. § 01.030 .
• Discretionary review ladder: many projects follow a predictable ladder:
  • Pre‑application / staff review and mapping (consult planning staff; planning may require utility/water letters for larger projects). See Ch. 30/31 processing references. Ch. 30; Ch. 31 .
  • Ministerial approvals or Director Review (Chapter 31) for limited actions; Minor Variance authority for Director reductions up to 10% is in § 01.041 (Director can grant up to a 10% reduction in standards under specific findings). § 01.041 .
  • Use Permits (Chapter 32) for conditional uses listed in the designation entries (e.g., mobile‑home parks, certain lodging projects, industrial uses); variances (Ch. 33) where statutory findings permit relief; appeals are heard under Chapter 47. Chs. 31–33; Ch. 47 .
  • Building permits: building‑permit submittal must also meet California building code standards (the County requires compliance with the current California Building Standards Code and other State technical standards as noted in Chapter 13 and Chapter 22). See Ch. 13 (commercial cannabis requires compliance with current California Building Code) and Ch. 22 (fire safe rules linked to building permits). Ch. 13; Ch. 22 .
• Environmental review: adoption or amendment of a Specific Plan and many large permits are projects under CEQA; Chapter 36 explains environmental review and when an EIR is required. § 36.040 .

State housing law in Mono County

• Accessory dwelling units: the County expressly permits Accessory Dwelling Units (ADUs) and references Chapter 16 – Accessory Dwelling Units across many land‑use entries (ADUs are allowed in SFR, RR, ER, AG, many residential and mixed‑use designations). See the ADU chapter reference in the designation texts (e.g., SFR, RR entries refer to Chapter 16). § 16 (Ch. 16 references in designation entries) . For statewide ADU standards and how state ADU law constrains local regulation see California ADU law (link below).
• Density and density bonus: the County references density processes and a density provision (see cross‑reference to § 04.100 Density in designation entries and the MFR/CL notes about density bonuses), but a clear, express local “density bonus” implementation text was not retrieved in the supplied excerpts; the designation entries reference density ceilings and the cross‑reference 04.100 for density policy. See designation entries and § 04.100 reference. § 04.100; MFR/CL entries .
• SB 9 / lot splits and statewide tenant protections: the uploaded County materials we reviewed emphasize local uses, ADUs and permit processes but do not explicitly mention SB 9 (two‑unit and lot‑split ministerial rules) or local rent‑control rules. For whether Mono County allows SB 9 ministerial two‑unit approvals/lot splits as a ministerial action, or whether the County has local rent control, verify with County planning staff or the Mono County Code — those items were not found in the retrieved excerpts. Not found in retrieved materials — verify with Mono County. .

Quick practical orientation (what a property owner should do)

1. Confirm your parcel’s land‑use designation on the County Land Use maps (General Plan Land Use maps are online; map references appear in § 01.060). § 01.060 .
2. Read the designation entry for the parcel to learn permitted uses, required minimum lot area, setbacks, coverage, and whether your proposal is allowed ministerially, by Director Review, or requires a Use Permit (each designation entry lists permitted uses and whether Director Review or Use Permit applies). Example: SFR, MFR, C, IP entries. SFR entry; MFR entry; C entry .
3. If your project is subject to design or discretionary review, consult Chapter 09 – Design Review and the processing chapters (Ch. 31–32) to understand submittal materials and hearings. Ch. 09; Chs. 31–32 .
4. If your project involves ADUs, consult Chapter 16 (ADU standards) and applicable state ADU law for ministerial limits and minimum standards; Chapter references for ADUs appear throughout the land‑use entries. Ch. 16; designation cross‑references .
5. For technical code compliance (structural, accessibility, fire protection), plan reviewers will require compliance with the California Building Standards Code / Title 24 and the County’s fire‑safety chapters (Ch. 22). Ch. 22; Ch. 13 .
