Overview
This page orients you to how land use is regulated in the unincorporated areas of Inyo County. The county’s zoning rules live in the Inyo County Code’s zoning title, which the county calls “Title 18. Zoning.” It lays out the official zoning map, the district families, the base and overlay rules, and the permit and review procedures that shape development across the Owens Valley and Eastern Sierra. Start by confirming your zoning on the county’s official map, then use the chapters below to find allowed uses, development standards, parking, and any overlays or discretionary reviews that apply.
Core rule of thumb: if a use or development standard isn’t allowed by your district or an overlay, you can’t do it—and any permit issued in conflict with zoning is “void and of no effect.” See the county’s “rules of application.”
How Inyo County’s code is organized
- Title name and scope: The county codifies zoning as Title 18. Zoning. It applies to territory outside incorporated cities and must conform to the General Plan.
- Zoning map: Zoning applies as shown on the “Zoning Map of the County of Inyo,” kept with the Clerk/Planning Department; map divisions and boundary determinations are covered in § 18.03.070–.090.
- Where district rules live: Districts are enumerated in § 18.03.060; each district has its own chapter with permitted/conditional uses and development standards (e.g., R‑1 in Chapter 18.30, C‑1 in Chapter 18.45, C‑2 in Chapter 18.48, M‑1 in Chapter 18.57).
- General regulations that apply countywide: The “Residential Districts—General” chapter and the “General Regulations” chapter include cross‑cutting rules like home occupations, nonconforming uses, ADUs, pollution prohibitions, and cannabis siting. See Chapters 18.27 and 18.78.
- Procedures and permits: Variances, conditional use permits (CUPs), applications/fees, amendments, and enforcement are in Chapter 18.81.
Zoning district families
The county divides unincorporated land into the following families, with symbols used on the zoning map (all per § 18.03.060). Use‑specific and dimensional standards are in each chapter.
- Residential: R‑1 (one family), R‑2 (multiple), R‑3 (multiple), RR (rural residential), RR‑0.5 Starlite Estates (special RR standard) — see R‑1 in §§ 18.30.010–.110; RR‑0.5 standards in § 18.22.050.
- Commercial: CB, C‑1 (general commercial‑retail), C‑2 (highway services/tourist), C‑3 (offices), C‑4 (heavy commercial), C‑5 (commercial recreation). See C‑1 in §§ 18.45.050–.080; C‑2 in §§ 18.48.050–.100; C‑4 and C‑5 in Chapters 18.49 and 18.54.
- Industrial: M‑1 (general industrial & extractive) and M‑2 (light industrial), with siting and performance standards in Chapters 18.57 and 18.56.
- Open space & public: OS (open space), P (public). OS and P appear in § 18.03.060; check the zoning map and district chapters for standards.
- Planning tools: PP (Precise Plan district; combines with a base zone; see Chapter 18.63), PUD (Planned Unit Development; see Chapter 18.66).
- Overlays and special districts: D (Architectural Design Control), SAHO (Snow Avalanche Hazard Overlay), AH (Airport Hazard; Chapter 18.62), DB (Density Bonus Overlay; Chapter 18.65), and the Nongroundwater‑Neutral Agricultural Use Overlay (Chapter 18.67).

Specific plans & overlays
- Precise Plan district (PP): Combines with a base district and carries the base lot and height limits unless a precise plan adds detail. See § 18.63.070–.080.
- Planned Unit Development (PUD): A reclassification tool; the Planning Commission recommends and the Board of Supervisors adopts with a final development plan required before building permits. See §§ 18.66.070–.110.
- Architectural Design (D) district: A design‑control overlay with a five‑member Architectural Design Review Board; approval of building plans is required before a building permit in D areas. See §§ 18.69.010–.030.
- Snow Avalanche Hazard Overlay (SAHO): Applies where a qualified avalanche study maps hazard; prohibits deflection devices that increase danger and requires recorded notice to owners. See §§ 18.64.010–.060.
- Airport Hazard (AH) standards: Limit heights in runway/approach surfaces; certain heights or concentrations of people require a CUP and FAA referral. See §§ 18.62.070–.080.

Building permits & review
- Zoning first: Every county permit or license must conform to Title 18; a permit issued in conflict is void. See § 18.03.100.
- Ministerial vs. discretionary: If your use is principally permitted in the district and not in a special design/overlay process, you typically proceed ministerially. Uses listed as “conditional” require a CUP with findings under § 18.81.100.
- Variances: Available for unique property conditions where strict application causes hardship; findings and procedures are in §§ 18.81.040–.090. See Inyo County Variances and Exceptions.
- Design review in D areas: Submit exterior elevations/materials; the Architectural Design Review Board must approve before a building permit. See § 18.69.030 and Inyo County Design Review.
- Mobile food facilities: Regulated countywide on private property; see Chapter 18.61 for definitions and permitting intent.
- Application logistics: Submittal forms/fees per §§ 18.81.160–.200; CUP terms and lapses are in § 18.81.140; county emphasizes voluntary compliance in enforcement (§ 18.81.370).
- Building code: Construction must meet the California Building Standards Code. Local chapters (e.g., D district) sometimes require approvals before the building permit issues.
Signage, if part of your project, must follow the county’s sign regulations; multiple districts cross‑reference Chapter 18.75 (see Inyo County Signage).
Nonconforming sites/structures are tightly managed (e.g., limits on enlargements, maintenance thresholds, and restoration after damage). See Inyo County Nonconforming Uses and §§ 18.78.230–.285.
State housing law in Inyo County
- ADUs/JADUs: The county allows Accessory Dwelling Units in all residential and mixed‑use zones and states that, where local standards conflict with State ADU law, state law controls. See § 18.78.340 and California ADU law.
- SB 9 two‑unit developments: Implemented locally via Chapter 18.84 for single‑family parcels in specified areas (e.g., Bishop urbanized area). The county provides objective standards such as minimum setbacks (rear/side 5 ft; may be 4 ft if needed to fit two 800‑sf units), possible 10 ft front setback, parking 1 per unit with transit/car‑share exemptions, and deed‑restriction requirements (no rentals under 30 days). See §§ 18.84.010–.020 and § 18.84 (standards D–H).
- Density bonus: Inyo adopts State Density Bonus Law; density and incentives/waivers follow Government Code with a local submittal/review process. See §§ 18.65.020, 18.65.050–.060.
- Rent regulations: Not found in retrieved materials within Title 18. Verify with the county for any separate tenant protection or rent‑stabilization ordinances. Not found in retrieved materials.

Where to read the Inyo County code
The Inyo County municipal and zoning code is published on eCode360 — view the official Inyo County code library. That lets you read the ordinance section by section.
GoCodebook goes beyond browsing eCode360 (see how they compare): it reads the Inyo County ordinance together with the California Building Standards Code and answers your question — zoning, setbacks, FAR, height, ADUs, permits — with the controlling citation for your parcel.
Who this affects
Frequently asked questions
What zoning districts does Inyo County have?
Unincorporated Inyo County uses symbols like OS, R‑1, R‑2, R‑3, RR, RR‑0.5 (Starlite), CB, C‑1, C‑2, C‑3, C‑4, C‑5, M‑1, M‑2, PP, PUD, D, P, and SAHO. Find them listed in the code’s district enumeration.
How do I check if my use is permitted and what setbacks apply?
Confirm your zoning on the official map, then open your district chapter for permitted/conditional uses and standards. For example, R‑1 sets a 25 ft front setback, 5 ft side yards and 20 ft rear yard with a max height of 35 ft/2.5 stories; C‑2 has a 25 ft front yard and allows 0 ft sides/rear unless abutting R.
Where are parking requirements?
They’re district‑specific. Examples: R‑1 requires 2 spaces per dwelling; C‑1 often requires 1/400 sf; C‑2 often 1/300 sf; M‑1 requires 1/employee plus guest/loading as needed. Your exact ratio is in your district chapter.
Do I need design review?
Only if you’re in a D (Architectural Design) district. In D areas, you must submit exterior elevations/materials and obtain Architectural Design Review Board approval before a building permit issues.
How does SB 9 work here?
Two‑unit developments are implemented via Chapter 18.84 for eligible single‑family parcels (e.g., within the Bishop urbanized area as defined). Objective standards include minimum rear/side 5 ft (or 4 ft if needed to accommodate two 800‑sf units), possible 10 ft front setback, 1 parking space per unit with transit/car‑share exemptions, and deed‑restriction limits (e.g., no rentals <30 days).
Can I add an ADU?
Yes. ADUs are allowed in all residential and mixed‑use zones, and the county acknowledges that State ADU law prevails if there’s a conflict with local standards. See § 18.78.340.
What if my building or use is nonconforming?
Nonconforming uses generally can’t expand; nonconforming buildings need approvals to enlarge. There are limited allowances for ordinary maintenance and for restoring some dwellings after damage. See §§ 18.78.230–.285 for details.
What permits and fees are required for a CUP or variance?
CUP and variance procedures, findings, timelines and fee rules are in Chapter 18.81. Applications follow forms set by the Planning Director, with fees per § 18.81.190; CUPs typically lapse after one year if not used.
Can I operate a mobile food facility on private property?
Yes, subject to county rules adopted in 2024 governing where and how mobile food facilities operate on private property in the unincorporated area. See Chapter 18.61 for scope and definitions.
Does Inyo County have rent control?
No rent‑control provisions were found in Title 18 (zoning). Check with the County for any separate tenant or rent ordinances outside Title 18. Not found in retrieved materials.
