Tehama County — Zoning

Zoning under the Tehama County local zoning and planning code, with the controlling citations.

Last reviewed: July 6, 2026

Overview

Tehama County’s zoning code governs only the unincorporated areas. Zoning districts, their purposes, permitted uses, and dimensional standards are set out in Title 17 of the County Code, with the official zoning map maintained by the Planning Director’s office, and any change reflected there after Board adoption per § 17.06.020 . The code is “permissive,” meaning a use is allowed only if it’s expressly listed for the district; anything not listed is prohibited under § 17.02.070 and applies throughout the unincorporated area (§ 17.02.060) .

Bottom line: In unincorporated Tehama County you can only do what your zoning district and any applicable combining/overlay districts expressly allow; confirm your parcel’s designation on the official zoning map (§ 17.06.020) and read the district’s permitted uses and standards (§ 17.02.070) before drawing plans.

For background on how zoning implements the General Plan’s land-use categories, see § 17.02.050 and our Tehama County Land Use guide . Parcel development also must meet countywide Development Standards (setbacks, yards, etc., see § 17.08.030) and any applicable Parking design standards (§ 17.08.080) .

Districts at a glance (general and combining)

Tehama County recognizes the following general districts (map symbols): AG-1, AG-2, AG-3, AG-4, TPZ, RE, R-1, R-2, R-3, R-4, C-1, C-2, C-3 (repealed), C-4 (repealed), G-R, M-1, M-2, PD, AV, PF, NR, PA; plus combining districts -A, -B, -S (repealed), -H, -P, -MH (§ 17.06.010) .

How to use the zoning map

Districts are shown on the County’s official zoning map kept at Planning; all boundary interpretations follow § 17.06.030 rules, and variances (see Tehama County Variances and Exceptions) may adjust a boundary on a single lot (§ 17.06.030.C) . Always confirm your parcel’s base district and any combining/overlay symbol before applying standards (§ 17.06.020) .

Checklist

Confirm parcel in unincorporated Tehama County and identify base zoning and any combining/overlay symbols on the official map (§ 17.06.020).
Verify the district’s purpose, permitted and conditional uses, and any special combining-district rules (§§ 17.06.010; 17.48 to 17.60).
Check lot standards (minimum area/width), setbacks, height limits, and any yard exceptions (§§ district chapter; 17.08.030–.040).
Determine if an ADU is planned and apply § 17.08.050 plus state California ADU law .
Apply Parking and loading standards (e.g., § 17.08.080; and district references) .
Screen for overlays like AV, PF, TPZ, NR, -A, Military, etc., and check any special standards (§§ 17.40; 17.42; 17.66; 17.44; 17.48; 17.69) .
If signs or exterior changes are proposed, consult Signage and any Design Review triggers.
For edge cases (nonconforming lots/structures/uses), confirm allowances under Nonconforming Uses (§§ 17.74.010–.050).

Risks & Ambiguities

Issue	Why it matters	What to verify
Williamson Act/FS contracts in AG/NR	Changes minimum parcel sizes and allowable uses; Board approval may be needed for some permits	Contract status and § 17.11.080; § 17.13.080; Chapter 17.65 (FS)
Combining districts (-A, -B, -H, etc.)	They override base standards (lot size, height, animals)	Map symbol suffixes and § 17.48; § 17.50; § 17.54; content for -P and -MH Not found in retrieved materials
Floodplain (PF) or Airport (AV)	Adds hazards/noise constraints and height caps	§ 17.42 and § 17.40; consult overlay maps and airport plans
TPZ eligibility and splits	Timberland criteria are specific; wrong split may be invalid	§ 17.66.040–.050 and forester plan requirements
Yard exceptions and fences	Small projections allowed; R-district fence limits can affect designs	§ 17.08.030; check district yards too
Communications facilities	Siting/height and stealthing conditions apply across districts	Chapter 17.71 tiers/height max 199 ft (§ 17.71.090)
Nonconforming status	Limits expansions/rebuilds; affects setbacks	§ 17.74.010–.050; get Planning’s determination

Plain-English Summary

For unincorporated Tehama County, your zoning district sets what you can build and where it fits on the lot. Find your district on the official map, then apply the district’s permitted uses and basic rules like minimum lot size, setbacks from the property line, and height limits. Special overlays like floodplain, airport zones, or timber production can layer on more rules. If it isn’t listed as allowed, assume it’s not — and ask Planning before you spend money on plans.

Frequently asked questions

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

R-1 is for single-family homes. You can build one-family dwellings with accessory structures and home occupations; limited crop/tree farming is allowed. Apply the R-1 dimensional rules (min lot 5,000 sq ft/60 ft width; front 50 ft CL/20 ft PL; sides total 20% width, min 6 ft; rear 20 ft; 35 ft height) per § 17.16.020 and § 17.16.040–.060. For ADUs, see § 17.08.050.

What are the basic setback rules for homes in unincorporated areas?

Most R and AG districts use a “50 ft from roadway centerline or 20 ft from property line, whichever is greater” front yard, with side and rear yards set by the district. See § 17.08.030 for countywide yard rules and each district’s yard section (e.g., R-1 § 17.16.040; AG-2 § 17.11.040).

Are ADUs allowed in rural zones like AG-2 or NR?

Yes. ADUs are allowed in R-1, RE, AG-1, AG-2, AG-3, AG-4, and NR, subject to § 17.08.050 (size, setbacks for conversions, utilities). State rules also apply; see our California ADU law.

I’m in AG-3 near El Camino Irrigation District — what’s the intent?

AG-3 targets rural living and small-farm/hobby-farm operations with limited keeping of animals. One rural single-family dwelling per legal parcel is typical; minimum lot size is 5 acres, with standard ag-style setbacks and a 35 ft height limit (§§ 17.12.010–.070). Expanded agritourism or heavy ag may require a use permit (§ 17.12.030).

What does TPZ zoning allow and how big must my parcel be?

TPZ is for timber production and related resource uses (roads/landings, habitat management, grazing). Parcels are typically very large; splits under 160 acres require stringent conditions and a forester-prepared plan. Front/side/rear yards are 100/50/100 feet (§§ 17.66.020, .040–.050).

Do I need to worry about airport or floodplain overlays?

Yes. The Airport (AV) district caps heights and limits certain uses in and near airport noise zones; PF (Primary Floodplain) limits structures/fill and requires flood-safe siting via use permit. Check § 17.40 and § 17.42 and confirm overlays on the zoning map (§ 17.06.020).

Are marijuana dispensaries allowed anywhere in unincorporated Tehama County?

No. Dispensaries are prohibited in all zoning districts by § 17.09.040.

How are nonconforming buildings handled if damaged?

If a nonconforming building is destroyed beyond one-half of its value, it must comply with current zoning upon rebuild (with a one-year allowance for dwellings) under § 17.74.040. Maintenance/expansion limits also apply (§ 17.74.010). See Nonconforming Uses.

What parking rules apply to a new commercial building?

Follow the general Parking and loading design standards (§ 17.08.080); district chapters often cross-reference these (e.g., C-2 § 17.26.070; C-1 § 17.24.070).

Where do I confirm my parcel’s zoning?

The County’s official zoning map is the controlling source and is maintained by the Planning Director’s office (§ 17.06.020). Ask Planning for the latest map sheet for your area.
