Tehama — Zoning
Zoning under the Tehama local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
Tehama's zoning is codified in Title 17 — ZONING (Ord. No. 198, 2023) and implements the city's General Plan by dividing the incorporated area into a small set of primary districts and targeted overlays. The Code emphasizes preserving Tehama's predominantly residential and agricultural/open-space character while allowing limited commercial use along a focused corridor. Always confirm parcel-specific designations on the official zoning map with the city; the ordinance declares a districting plan is adopted for all incorporated land § 17.04.010.
Practical note: when you read dimensional rules, also check the Tehama Development Standards and Tehama Parking guidance because Title 17 ties permitted uses to both zone standards and these cross-cutting rules.
Residential district (R)
Purpose and where it applies
- The Residential district (referred to in the Code simply as R) covers all platted lots and blocks inside the incorporated area; unplatted areas are treated separately as Open-space (§ 17.08.010). The district's purpose is to provide for a variety of housing types and related neighborhood uses.
Typical permitted uses (high‑value items)
- Single‑family dwellings (one- or two-story) with two off‑street parking spaces and minimum dwelling dimensions: 20 ft width and 800 sq ft floor area for the dwelling (§ 17.12.030 A).
- Multifamily housing, child day care homes, community care (small), transitional/supportive housing, ADUs/JADUs (see the ADU chapter) (§ 17.12.030).
Key dimensional standards (what will drive site layout)
- For single‑family buildings: maximum coverage 35%, minimum front setback 15 ft, side yards totaling at least 20% of lot width (no side < 6 ft; corner street side ≥ 10 ft), maximum height two stories, rear yard 20 ft for main residence / 6 ft for other buildings (§ 17.12.050 A).
- For multifamily: maximum coverage 65%, front 15 ft, same side‑yard formula, max height up to 35 ft / 2–3 stories, rear 20 ft / 6 ft for secondary structures (§ 17.12.050 B).
Other rules and constraints
- Minimum lot size for subdivision inside R: lots may not be re‑subdivided to less than 12,800 sq ft (§ 17.12.070) — important if you plan lot splits or duplex infill.
- Accessory Dwelling Units (ADUs) are allowed by right in any zone that allows residential uses; ADU-specific standards and ministerial approval timing are in Chapter 17.60 (see the ADU chapter and the state rules) (§ 17.60.040 - 17.60.050). For ADU design/foundation and sprinkler rules, consult the California Building Standards Code as the Code requires compliance with state building standards in the ADU chapter (§ 17.60.030, § 17.60.080).
Where to check
- Confirm the parcel is actually mapped R on the official zoning map (Title 17 adopts a districting plan but the ordinance text does not reproduce the map file). § 17.04.010.
Relevant Code citations: §§ 17.08.010, 17.12.030, 17.12.050, 17.12.070, 17.60.030–080.
Business Overlay Zone (BOZ)
Purpose and where it applies
- The Business Overlay Zone (BOZ) is an overlay applied to select parcels (notably along C Street) to allow commercial uses while retaining the underlying residential base zone standards; it implements the general plan's business overlay land use (§ 17.14.020).
Permitted uses (decision‑relevant list)
- At the discretion of the City Administrator (absent a revocable use permit) the BOZ allows: all residential district uses plus banks/ATM, equipment sales/rental, hotel/motel, offices, personal services, outdoor dining, restaurants, retail (general), single‑room occupancy (SRO) (§ 17.14.030).
Conditional uses
- Light industrial, alcohol sales, bars, restricted personal/retail services, veterinary clinic, and community care (large) are conditional uses that require a revocable or conditional permit (§ 17.14.040).
Standards and limits
- The overlay defers to the underlying base zone's development standards (setbacks, coverage, height) and keeps the same lot subdivision limit as the residential district (12,800 sq ft minimum for BOZ lot splits) (§ 17.14.050, 17.14.070).
Design review and signage
- Sign rules in the BOZ reference the same sign limits used elsewhere in the Code; consult the Tehama Signage page and § 17.14.060 for business‑sign size restrictions and prohibited signs.
Open‑space district (Open-space)
Purpose and where it applies
- Open-space covers unplatted lands and riverfront frontage inside the incorporated boundary; the district is reserved for parks, river access, wildlife preservation, recreation, and agriculture (production of food and fiber) (§ 17.08.010–020, § 17.16.010).
Permitted uses and limits
- Typical permitted uses are agricultural production, parks, and public recreation (river bank access/control). Improvements (streets, sewers, public buildings) in Open‑space require planning commission referral and a finding of conformity with the open‑space plan prior to construction (§ 17.16.010 B).
Renewable energy and special uses
- The Code implements narrower rules for energy systems: small solar and small wind are allowed in the Residential and Open‑space districts under specific conditions, while larger solar/wind facilities are restricted and may require a conditional use permit (§ 17.84.030, § 17.83.030). Check Chapters 17.83–17.84 for the full allowances and siting/height setbacks.

Checklist
- Verify the parcel's zoning designation on the official zoning map (Title 17 adopts a districting plan) — § 17.04.010.
- Confirm the applicable district (R, BOZ, Open‑space) and applicable chapter(s) (§ 17.12, 17.14, 17.16) and read permitted vs. conditional uses.
- Check dimensional standards: coverage, setbacks, height from § 17.12.050 A–B (single‑family vs. multifamily) and subdivision limits § 17.12.070.
- For commercial projects in the BOZ, confirm whether the use is permitted or conditional under § 17.14.030–040.
- If adding an ADU, follow Chapter 17.60 and the ministerial permitting timeline; check Tehama ADUs and state ADU law for exceptions.
- For variances, use permits, or revocable permits, follow Chapter 17.28 application, hearing, findings and notice rules. Verify the application materials and fee. § 17.28.010–060.
- Check overlay districts (BOZ, any historic overlay) under Tehama Overlay Districts and consult Tehama Design Review when design guidelines apply.
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Zoning map file / parcel designation | The ordinance adopts a districting plan but the text does not include a full map image; specific parcel rules depend on mapped zone | Verify the official, current zoning map with the City of Tehama (not found in retrieved materials). § 17.04.010 |
| Applicability of BOZ on a parcel | BOZ is an overlay and may only apply to select parcels (not entire blocks) — affects permitted commercial uses | Confirm whether the parcel sits inside the Business Overlay Zone (map/overlay registry) and any revocable permit history. § 17.14.020–030 |
| Floodplain / FEMA constraints | Multifamily by‑right allowances under SB35 still require FEMA/flood rules compliance per the Code | Check FEMA flood maps and the city's flood‑zone implementation instructions for the parcel. § 17.12.080 |
| Historic district design review | ADU design and other work in a historic district may be subject to additional local design guidelines not in Title 17 | If the parcel is in a historic overlay, consult Tehama Historic Preservation and verify specific overlay rules (not reproduced in the retrieved textual snippets). |
| Subdivision minimums vs. state density law | The local 12,800 sq ft split limit could conflict with infill/density programs or state housing mandates | Verify whether state law or local general plan amendments affect lot division in your case. § 17.12.070, § 17.14.070. |
Plain‑English Summary
Tehama's Title 17 zones almost all platted, built‑lot areas as Residential (R) with predictable setbacks and coverage rules (e.g., 15 ft front, 35% coverage, 6 ft minimum side), applies a limited Business Overlay Zone (BOZ) to a few parcels (C Street corridor) to allow neighborhood commercial uses, and treats the rest as Open‑space for parks/agriculture — check the official zoning map before you act and follow Chapter 17.60 for ADU rules.

Frequently asked questions
What can I build on an R lot in Tehama?
You can build one‑ or two‑story single‑family homes (minimum 20 ft width and 800 sq ft) and the other uses listed in § 17.12.030 (multifamily, child day care homes, small community care, ADUs/JADUs, supportive/transitional housing). Dimensional rules (coverage, setbacks, heights) are in § 17.12.050 so design around the 35% coverage and 15 ft front setback.
What are Tehama setback requirements for single‑family homes?
Residential setbacks: 15 ft front, side yards totaling 20% of lot width with no side less than 6 ft (corner street side 10 ft), and 20 ft rear for main residence (§ 17.12.050 A).
Do I need a use permit to operate a small shop in the Business Overlay Zone?
Many neighborhood commercial uses (restaurants, retail, offices, banks) are permitted in the BOZ at the City Administrator’s discretion (§ 17.14.030). Some uses (light industrial, alcohol sales, bars, certain clinics) are conditional and require a use permit under § 17.14.040 and Chapter 17.28 procedures.
Can I add an ADU in Tehama and how long does permitting take?
ADUs are allowed by‑right in any zone permitting residential uses; ministerial approval is required and the Code references a 60‑day processing target for complete building permit applications under § 17.60.050. ADU design/foundation/sprinkler requirements are tied to the California building code as noted in Chapter 17.60.
What does “Open‑space” allow along Tehama’s riverfront?
Open‑space allows parks, river access, wildlife preservation, recreation and agricultural production; any improvements (streets, sewers, public buildings) require planning commission referral and a council finding of conformity with the open‑space plan (§ 17.16.010 B).
If my lot is in a historic overlay, do Title 17 ADU rules change?
Title 17 requires ADUs to be compatible with historic district design guidelines where applicable; Chapter 17.60 references compliance with applicable historic‑district guidelines and local design review may apply. Verify the overlay rules and design review triggers.
What standards control solar or wind installations on my Tehama property?
Small solar and small wind installations are allowed in certain districts with district setbacks and height limits; larger solar/wind facilities are restricted or require a use permit (see Chapter 17.84 for solar and Chapter 17.83 for wind energy systems). Check Williamson Act restrictions for agricultural contracts.
How small can a lot be split inside the Residential or BOZ areas?
Local subdivision rules prohibit dividing lots in the residential or business overlay into parcels smaller than 12,800 sq ft (§ 17.12.070, 17.14.070). Always verify whether a parcel is actually in the BOZ and whether any state/local exceptions apply.
