Overview

Calaveras County’s zoning rules are codified in Title 17 of the Calaveras County Municipal Code and apply only in the unincorporated areas of the County. Title 17 sets up base zoning districts, overlay zones, countywide standards, and an official zoning map that together govern what can be built, where, and at what intensity. All approvals must be consistent with the County’s General Plan and any applicable specific plan. See the countywide overview for context and links to related topics at the Calaveras County zoning & planning overview (the ordinance title is “Calaveras County Zoning Code” under Title 17) .

The Official Zoning Map is the controlling record of zoning boundaries in unincorporated Calaveras County; if a parcel straddles two zones, each zone’s rules apply to the portion within that zone, as interpreted by the Planning Director (§ 17.03.020). Always verify your parcel’s base zone and overlays on the Official Zoning Map before designing a project .

How Calaveras County’s Zoning Code is organized

  • Title and applicability: The Zoning Code is Title 17, and it governs all property and development in the unincorporated areas of Calaveras County (§ 17.01.010; § 17.01.050) .
  • Zoning districts and map: Base and overlay zoning districts are listed in § 17.03.010; the Official Zoning Map is maintained by the County (§ 17.03.020) .
  • Countywide standards: Setbacks, height exceptions, slopes over 50%, and related rules appear in countywide regulations in Chapter 17.16 (cross‑referenced throughout district tables) .
  • Development must remain consistent with the General Plan (§ 17.01.040) and, in mapped areas, with specific plans (§ 17.15.020) .

Zoning Districts and Overlays in Unincorporated Calaveras County

The County divides land into base zones and may apply one or more overlays. Quick index of symbols appears in § 17.03.010 .

Resource Zones

These zones support agriculture, timber, and working lands (§ 17.04.010). Typical patterns include larger setbacks and a single primary dwelling per legal lot; agricultural buildings may have different height allowances. See § 17.04.030 for standards .

  • GF (General Forest) — Purpose: commercial timber and related uses. Typical uses: timber production, wildlife management; one dwelling per legal lot. Key standards: setbacks generally 30 ft yards; 35 ft height (agricultural buildings not subject to the 35 ft cap); see § 17.04.030 . Where: forest lands consistent with Resource General Plan categories (§ 17.04.010) .
  • TP (Timber Production) — Purpose: implements the Forest Taxation Reform Act; primary use is timber preserves. Standards: similar setbacks; subdivision below 160 acres restricted; long-term TP zoning mechanics in § 17.04.010 and § 17.04.020 notes (§ 17.04.010; TP subdivision rule) .
  • A1 (General Agriculture) — Purpose: general farming and ranching; residential is secondary. Standards: one dwelling per legal lot; 30 ft setbacks; 35 ft height (ag buildings exempt from cap); § 17.04.030 .
  • AP (Agriculture Preserve) — Purpose: Williamson Act lands and intensive agriculture; uses must be consistent with Williamson Act contracts (§ 17.04.010) . Standards: as in § 17.04.030 (e.g., 30 ft setbacks; 35 ft height) .
  • RA (Residential Agriculture) — Purpose: small‑scale/personal agriculture alongside larger residential parcels. Standards: 1 dwelling per legal lot, 30 ft setbacks, 35 ft height; see § 17.04.030; additional rural road maintenance rules may apply in some districts (§ 17.04.040) .

Residential Zones (§ 17.05)

Residential standards emphasize density tied to infrastructure and consistent setbacks (§ 17.05.030). ADUs are allowed per § 17.25.040 (see ADU notes below) .

  • RR (Rural Residential) — Purpose: large‑lot homes with accessory ranching primarily for personal use (§ 17.05.010). Uses: single‑unit homes, ADUs, limited ag‑related activities with limits (§ 17.05.020). Key standards: maximum density 1 dwelling per legal lot; 20 ft front and street‑side or 50 ft to centerline—whichever yields greater setback; 10 ft interior side; 20 ft rear; 35 ft height (§ 17.05.030) .
  • R1 (Low Density Residential) — Purpose: low‑density neighborhoods served by public water and sewer (§ 17.05.010). Standards: same setbacks as RR except 5 ft interior side; 35 ft height (§ 17.05.030) .
  • R2 (Medium Density Residential) — Purpose: duplexes and small multifamily in areas with utilities (§ 17.05.010). Standards: max density 12 du/ac; minimum density 6 du/ac where public water and sewer exist; 5 ft interior side; 35 ft height (§ 17.05.030) .
  • R3 (High Density Residential) — Purpose: multifamily and higher densities where utilities exist (§ 17.05.010). Standards: max 20 du/ac; minimum 12 du/ac where public water/sewer exist; 10 ft interior side; 45 ft height (§ 17.05.030) .

ADUs: One or more accessory dwelling units may be allowed; they do not count toward density, have ministerial approval timelines, and include minimum 4 ft side/rear setbacks for detached/attached ADUs (§ 17.25.040) . Additional requirements include no on‑site ADU parking in many cases and well capacity criteria when not on public water; see § 17.25.040.G–J and related subsections. For state context, see California ADU law but apply County standards locally (§ 17.25.040) .

Commercial Zones (§ 17.06)

  • HC (Historic Center) — Purpose: historic main streets and mixed‑use nodes. Standards: up to 12 du/ac residential; 0 ft front/street‑side or 30 ft to street centerline, whichever yields greater setback; 5 ft interior sides where adjacent to non‑commercial; 20 ft rear where adjacent to Residential; 35 ft height (§ 17.06.040) .
  • C1 (Local Commercial) — Neighborhood‑serving retail/services. Standards: up to 20 du/ac; similar setbacks and 35 ft height (§ 17.06.040). Residential must be above/behind street‑facing commercial, with possible CUP modifications (§ 17.06.030) .

Residential in commercial zones must place residential above or behind primary commercial street frontage; the ground floor along the street must carry minimum commercial depth/percentage unless waived via CUP (§ 17.06.030) .

Industrial Zones (§ 17.07)

  • M1 (Light Industrial) — Light manufacturing, R&D, warehousing, and compatible public/semi‑public uses (§ 17.07.010). Standards: 45 ft height; typical front 30 ft or 60 ft from centerline (greater governs); similar street‑side; one caretaker unit max; FAR varies by utilities (§ 17.07.030) .
  • M2 (General Industrial) — Heavier manufacturing/processing with protections for neighbors (§ 17.07.010). Standards mirror M1; broader industrial use allowances; see use table (§ 17.07.020) and standards (§ 17.07.030) .
  • M4 (Business Park) — Employment campuses and supportive services (§ 17.07.010). Standards: similar to M1; see tables (§ 17.07.020–.030) .

Selected use controls: e.g., outdoor storage, salvage/wrecking, and certain recreation uses require permits or are restricted (§ 17.07.020; see notes) and must also meet countywide screening rules; also review Calaveras County Landscaping and Screening and Calaveras County Signage references as applicable .

Public & Semi‑Public Zones (§ 17.08)

  • PS (Public Service) — Public facilities/utilities. Standards: FAR varies by services; no fixed height cap in PS; setbacks typically 20/50 ft front/street‑side (greater governs) (§ 17.08.030) .

  • OS (Open Space) — Permanent open space/resource areas; typically 24 ft height; larger setbacks (§ 17.08.030) .

Overlay Zones (combine with a base zone)

  • -AO (Airport Overflight) — Adds airport safety, height, and noise rules within the Airport Influence Area; uses must be compatible with the Airport Land Use Compatibility Plan; interior noise standards apply and FAA Part 77 height limits control (§ 17.09.010–.070) .
  • -EP (Environmental Protection) — Requires a resource protection or mitigation plan and CEQA/NEPA compliance before approving use/disturbance in mapped areas (§ 17.10.040–.050) .
  • -DR (Design Review) — Triggers design review in mapped communities (e.g., parts of Mokelumne Hill) per Chapter 17.29; shown as “-DR” on the map (§ 17.11.010–.030) .
  • -X (Parcel Size Limitation) — Identifies parcels with specific minimum lot size or no‑further‑subdivision conditions (e.g., density transfers or HOA/common areas); mapped as “-X” (§ 17.12.010–.030) .
  • -ME (Mineral Extraction) — Implements SMARA‑based permitting, reclamation, inspections, and financial assurances for surface mining; mineral resource protection policies also apply (§ 17.13.010–.110; § 17.13.190) .
  • -PD (Planned Development) — Custom development standards by adopted PD Plan for integrated projects; cannot overlay GF/TP/A1/AP; minimum area generally 5 acres; PDs are adopted with findings and govern subsequent permits (§ 17.14.010–.060) .
  • -SP (Specific Plan) — Where adopted, the specific plan governs land use and standards; the SP overlay is applied by ordinance and subsequent approvals must be consistent (§ 17.15.010–.040; § 17.40.050–.080) .

Quick-glance Residential Standards

These are commonly referenced standards; confirm parcel‑specific exceptions in the development tables and Calaveras County Development Standards.

Zone Max Density Min Density (with public water/sewer) Height Front/Street-side Setback Rule Interior Side Rear Code Reference
RR 1 dwelling per legal lot None 35 ft 20 ft from property line or 50 ft from roadway centerline, greater governs 10 ft 20 ft § 17.05.030
R1 1 dwelling per legal lot None 35 ft Same as RR 5 ft 20 ft § 17.05.030
R2 12 du/ac 6 du/ac 35 ft Same as RR 5 ft 20 ft § 17.05.030
R3 20 du/ac 12 du/ac 45 ft Same as RR 10 ft 20 ft § 17.05.030

Practical tips:

  • ADUs: Detached/attached ADUs can encroach to 4 ft side/rear; they do not count against density; ministerial processing timelines apply (§ 17.25.040) .
  • Setbacks measured from property lines unless the centerline rule applies; see tables and countywide setback rules (§ 17.16.080 cross‑referenced in tables) .

Commercial and Industrial Snapshots

  • Commercial height/setbacks: HC/C1/CP are generally 35 ft max height (C2 is 45 ft); front and street‑side are 0 ft or 30 ft to centerline, whichever yields the greater setback; residential allowed above/behind storefronts (§ 17.06.030–.040) . See Calaveras County Parking for stall/layout standards cross‑referenced by the zoning tables.
  • Industrial standards: M1/M2/M4 max height 45 ft; front/street‑side typically 30 ft or 60 ft to centerline; FAR varies by utilities; one caretaker unit per site permitted (§ 17.07.030) .

Using the Official Zoning Map

  • The map and its legends are part of the Zoning Code by reference; check overlays and any numeric suffixes (e.g., R2(12) for density; “-X” parcel size limitation). Boundary uncertainties are resolved by rules in § 17.03.020 and by the Planning Director’s determination for split‑zoned parcels (§ 17.03.020) .
  • For broader policy fit, cross‑check with Calaveras County Land Use.

Other ordinance touchpoints you’ll likely use

Checklist

  • Confirm your parcel’s base zone and overlays on the Official Zoning Map (§ 17.03.020) .
  • Check permitted, administrative, and conditional uses for your zone (district land use tables in §§ 17.04–17.08) .
  • Apply development standards: density, height, setbacks, and FAR from your district’s table; don’t miss “greater of property line or centerline” front/side rules (§§ 17.04.030; 17.05.030; 17.06.040; 17.07.030) .
  • If adding an ADU, confirm § 17.25.040 allowances, setbacks, and ministerial timeline; coordinate with California ADU law as needed (§ 17.25.040) .
  • Verify overlay triggers (AO noise/height, EP resource plans, DR review, X parcel limits, ME mining, PD/SP plans) (§§ 17.09–17.15) .
  • Cross‑check countywide standards (slopes ≥50%, access, height exceptions) in Chapter 17.16 and applicable Development Standards (§ 17.16.050; § 17.16.090) .
  • Confirm Parking, screening/landscaping, and signage applicability for commercial/industrial or public uses (§ 17.16.100–.110; § 17.24.120) .
  • If your project falls within a historic area or DR overlay, plan for Design Review (§ 17.11.020) and consider the California Building Standards Code for construction-phase compliance.

Risks & Ambiguities

Issue Why it matters What to verify
Split‑zoned parcels Different rules can apply to different portions of the same parcel Director’s boundary call and which district applies where (§ 17.03.020)
Front setback “property line vs centerline” The greater distance governs; can materially change site plans Use the correct frontage measurement per your district table (§§ 17.05.030; 17.06.040; 17.07.030; 17.08.030)
Minimum densities in R2/R3 Underbuilding may be inconsistent with standards where utilities exist Confirm utility availability; apply minimum density where required (§ 17.05.030)
Residential in Commercial zones Street‑level activation rules can block ground‑floor housing Follow “upper stories/behind” rule or obtain a CUP (§ 17.06.030)
Airport Overflight constraints Height limits/noise mitigation can change building design AO overlay mapping, FAA Part 77 surfaces, and interior noise standards (§ 17.09.060–.070)
EP overlay resource plans Additional studies/mitigation can add time/cost Need for a resource protection/mitigation plan and CEQA/NEPA compliance (§ 17.10.040–.050)
ADU water/well capacity Non‑public water ADUs have source capacity criteria Environmental Health well capacity thresholds (§ 17.25.040.I)
PD/SP governance Custom standards override base zoning where adopted Whether a PD Plan or Specific Plan governs your parcel (§§ 17.14.060; 17.15.020)

Plain-English Summary

In unincorporated Calaveras County, your parcel’s base zone sets allowed uses, density, setbacks, and height; overlays can add rules (airport safety, design review, resource protection, or a custom PD/SP plan). Always start with the Official Zoning Map, then confirm the district table standards, any overlay requirements, and countywide rules that may change the numbers you use for design and site planning (§§ 17.03.010–.020; district tables) .

Frequently asked questions

What can I build on a Rural Residential (RR) lot in unincorporated Calaveras County?

RR is for large‑lot single‑unit homes with accessory residential/ag uses primarily for personal scale. Typical allowances include a primary dwelling and an ADU; check the RR land use table for any administrative or conditional permits for specific activities (§ 17.05.020). Key standards include a 20 ft or 50 ft (to centerline) front/street‑side setback, 10 ft interior side, 20 ft rear, and 35 ft height (§ 17.05.030) .

What are the baseline residential setbacks and heights?

In R‑districts, front/street‑side is the greater of 20 ft from property line or 50 ft from the roadway centerline; interior sides are 10 ft in RR, 5 ft in R1/R2, and 10 ft in R3; rears are 20 ft. Heights are 35 ft in RR/R1/R2 and 45 ft in R3 (§ 17.05.030) .

Can I put residential units in a commercial zone?

Yes, but residential must be located above or behind commercial street frontage; the ground‑floor commercial depth/percentage standards apply unless a CUP waives them due to site/context (§ 17.06.030). Residential densities vary by commercial zone (e.g., C1 up to 20 du/ac; C2 up to 6 du/ac) and standard commercial setbacks apply (§ 17.06.040) .

What does the Airport Overflight overlay (-AO) change for my project?

It imposes airport safety, height, and noise compatibility limits. New projects must meet FAA Part 77 height criteria and interior noise standards (e.g., CNEL 45 dB inside single‑unit dwellings); uses must be consistent with the Airport Land Use Compatibility Plan (§ 17.09.040–.070) .

Do ADUs count against my zoning density?

No. ADUs are deemed consistent with the lot’s zoning and do not count toward allowable density; they can be approved ministerially and often use reduced side/rear setbacks of 4 ft (§ 17.25.040) .

How do I know if a Specific Plan or Planned Development governs my site?

Check the Official Zoning Map for “-SP” or “-PD” after your base zone. Where adopted, a Specific Plan or PD Plan governs use and development; consistency is required for subsequent approvals (§ 17.15.020; § 17.14.060) .

What if my parcel has more than one zoning district?

Each zone’s regulations apply to its respective portion. The Planning Director determines the zoning boundary location on split‑zoned parcels per § 17.03.020; design to comply with the stricter portions where appropriate and verify before submittal .

Are there extra rules in resource or rural areas?

Yes. Resource zones (GF/TP/A1/AP/RA) have larger setbacks, resource‑focused purposes, and sometimes supplemental standards like rural road maintenance requirements for certain nonresidential uses (§ 17.04.040). Confirm minimum parcel sizes and any Williamson Act or TP constraints (§ 17.04.010–.040) .

Do I need design review?

Only if your property is inside a mapped Design Review overlay (e.g., parts of Mokelumne Hill) or a community area where the Board adopted design standards; then Chapter 17.29 applies (§ 17.11.020–.030). Check the Official Zoning Map for “-DR” .

How do slopes over 50% affect my project?

Parcels with slopes ≥50% may trigger increased lot sizes, engineered plans, erosion control, or even denial until safe/adequate measures are in place (§ 17.16.050). Many district tables cross‑reference this provision; plan early for geotechnical design in steep areas .
