Tehama County — Variances and Exceptions

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

Last reviewed: July 6, 2026

Overview

This page distills how variances and exceptions work under Title 17 (Zoning) of the Tehama County Code for projects in the unincorporated areas. Variances are narrowly tailored relief from area-type zoning standards; “exceptions” are targeted flexibilities embedded elsewhere in the code (for example, parking and lot line adjustments). Use this in tandem with the county’s zoning framework, land use, and development standards.

Plain-English core rule: A variance in unincorporated Tehama County is only for area, height, coverage, space, or nonconforming-use regulations—and only when special property circumstances create hardship not of the owner’s making; it cannot authorize a prohibited use and must be consistent with the General Plan on balance. See § 17.72.010 and § 17.72.020 for the controlling tests.

What counts as a “Variance” in Tehama County

Scope: Relief can be granted from “area, height, coverage, or space requirements” and certain rules for nonconforming uses; this is not a use variance. See § 17.72.010.
Required showings with the application (summarized):
- Special property circumstances (size, shape, topography, location, surroundings) deprive privileges other similar-zoned properties enjoy.
- Applicant accepts conditions so no special privilege is conferred.
- A hardship peculiar to the property exists and was not self-created; purely personal/financial issues don’t qualify, and prior variances set no precedent.
- No material detriment to public health/safety/welfare or adjacent light/air.
- Either the variance is insignificant vis-à-vis the General Plan, or the hardship relief outweighs potential adverse General Plan effects. See § 17.72.020(A)–(E).
Process highlights: Public hearing (Planning Commission), noticing per § 17.70.030 referenced in § 17.72.030, written findings required, possible revocation, and appeal rights. See § 17.72.030–.050, .060.

When you should seek an Exception (not a Variance)

Tehama County’s code embeds specific exceptions you might use instead of a variance:

Parking exceptions via use permit: The County can approve exceptions/modifications to off-street parking standards if the approved design is of equal or greater excellence, or if an existing facility lacks feasible space to provide full parking. See § 17.08 (Off‑Street Parking)—exception clause.
- Use-permit findings apply under § 17.70.040.
- Cross-check related parking layouts and counts before you apply.
Setback “adjustments” for legally nonconforming structures: The Planning Director may approve a setback adjustment to allow additions to a structure deemed legally nonconforming by § 17.74.010, subject to limits. See § 17.08.030(B).
- Review nonconforming uses first.
Lot line adjustments as a relief valve from minimum parcel sizes: The County allows certain adjustments that don’t create more lots and that maintain parcel sizes at or above specified minimum thresholds (often 80% of the district’s minimum). See § 17.75.020–.030.
Planned Development flexibility: In the PD district, regulations “may be varied” when it improves design and arrangement; this is built into the district. See § 17.38.080.

Boundaries and overlays that affect variance strategy

Moving a mapped zoning boundary inside a single lot: The location of a district boundary that divides a lot may be adjusted by applying the variance procedure in § 17.72. See § 17.06.030(C).
Prohibited uses remain prohibited: A variance or any other entitlement cannot legalize uses the County bars in all districts (e.g., marijuana dispensaries). See § 17.09.040.
Density bonus and housing concessions: For qualifying housing, requests to waive/modify development standards proceed through existing County permit processes (often a use permit), not through variances. See § 17.80 (Density Bonus), subd. O.
- Coordinate early with design review and landscaping/screening, and keep overlay districts constraints in mind.

District-by-district: Where the code itself provides flexibility levers

Below are the districts for which the retrieved code expressly ties variances/exceptions to district standards in the unincorporated areas. For other districts, use the general variance pathway above and consult Tehama County Zoning.

AG-1 (Agricultural/Upland)

Purpose: Recognize upland grazing, allow compatible ag and non-ag uses, and conserve open space/resources. See § 17.10.010(A).
Typical permitted uses: Not found in retrieved materials.
Key dimensional standards: For subdivisions, permitted density is determined by dividing total acreage by the minimum parcel size of the district; smaller “clustering” lots may be allowed if overall density is met and a no-further-division instrument is recorded. See § 17.68.020(B), § 17.68.020(C).
Lot line adjustments: Must not create more lots and must respect size thresholds (generally not less than 80% of minimums where applicable). See § 17.75.020.
Where it applies: Unincorporated areas; confirm mapped boundaries with zoning.

AG-2, AG-4, and NR (Natural Resource)

Purpose: Not found in retrieved materials.
Typical permitted uses: Not found in retrieved materials.
Key dimensional standards: Lot line adjustments in these zones may not result in any lot less than 80% of its minimum parcel size (with access, frontage, and service standards met). See § 17.75.020(D).
Where it applies: Unincorporated areas; verify parcel’s district and General Plan consistency.

AG-3

Purpose: Not found in retrieved materials.
Typical permitted uses: Not found in retrieved materials.
Key dimensional standards: Lot line adjustments may not create lots under five gross acres (non‑Williamson Act) or under forty gross acres (Williamson Act/Farmland Security Zone). See § 17.75.020(E) and Williamson Act findings in § 17.75.030.
Where it applies: Unincorporated areas; confirm Williamson Act contract status.

Residential zones (R districts; general reference)

Purpose: Not found in retrieved materials.
Typical permitted uses: Not found in retrieved materials.
Key dimensional standards: Residential lot line adjustments between conforming parcels cannot produce lots under 80% of the minimum parcel size (subject to access and service standards). See § 17.75.020(C).
Where it applies: Unincorporated residential districts; verify which R classification applies on your parcel.

PD (Planned Development)

Purpose: Enable planned developments on suitable acreage. See § 17.38.010.
Typical permitted uses: All R, C, M, and S district uses when approved by use permit. See § 17.38.030.
Key dimensional standards: Yards, lot area, height, coverage are set case‑by‑case in the PD’s use permit; off‑street parking is required (minimums specified, with Commission discretion to require more for commercial). See § 17.38.040–.070.
Built-in flexibility: PD regulations “may be varied” to achieve improved design and arrangement. See § 17.38.080.

Practical notes

The zoning title declares its standards are minimums applied countywide in the unincorporated areas and that conflicts are resolved in favor of the more restrictive standard. See § 17.02.030–.040, .060.
Variances cannot be used to bypass state building rules; separate compliance with the California Building Standards Code is required. Not a zoning relief; verify with the jurisdiction. Also note that some floodplain variances are governed by state building code rules, not by Title 17. Not found in retrieved materials.

Checklist

Confirm the parcel is in the unincorporated area and identify its zoning/overlays using Tehama County Zoning and Overlay Districts.
Decide if you need a variance or if a code-built exception (parking, setback adjustment for nonconforming structures, lot line adjustment, PD flexibility) fits better. See § 17.08.030(B), § 17.75.020–.030, § 17.38.080.
For a variance: prepare a written application addressing each required finding in § 17.72.020(A)–(E), with site plans and evidence of special property circumstances and non‑self‑created hardship.
Anticipate conditions of approval to avoid special privilege and mitigate impacts; know that noncompliance can trigger revocation under § 17.72.050.
Calendar the public hearing and noticing under § 17.72.030; be ready for Commission questions and to accept reasonable conditions.
If denied, assess appeal options under § 17.72.060 or consider redesigns that use a code exception or a design review path.

Risks & Ambiguities

Issue	Why it matters	What to verify
“Use” variance requests	Title 17 allows only area-type variances; using it to permit a prohibited or conditionally disallowed use will fail	Confirm your end use is permitted/conditionally permitted in the base district; see prohibitions like dispensaries in § 17.09.040
Self-created hardship	Financial/personal issues aren’t valid hardship; owner-created constraints sink findings	Your narrative under § 17.72.020(C) should focus on physical/property circumstances
General Plan consistency	Variances that conflict with the Plan are risky unless hardship outweighs effects	Align with land use designations; address § 17.72.020(E) in your findings
Boundary-split lots	Zoning lines through parcels complicate setbacks/uses	Consider a boundary-location variance under § 17.06.030(C); prepare scaled exhibits
Parking relief vs. variance	Parking exceptions run through a use permit with a different finding set	Use § 17.08 (Parking exception clause) plus § 17.70.040 findings; don’t file a variance by default
Nonconforming structures	Additions into setbacks may be doable without a variance	Confirm “legally nonconforming” status and request a setback adjustment per § 17.08.030(B)

Plain-English Summary

In unincorporated Tehama County, a variance is a carefully limited tool for unusual parcels with real physical constraints—it can tweak setbacks, height, lot coverage, or similar rules when strict application would be unfair and not harm neighbors or the General Plan. Before seeking a variance, check built‑in exceptions such as parking relief by use permit, nonconforming-setback adjustments, lot line adjustments, or PD flexibility.

Frequently asked questions

Can I get a “use variance” to allow a use not otherwise permitted on my lot?

No. Tehama County’s variance authority is limited to area/height/coverage/space and certain nonconforming regulations; it is not a use variance. See § 17.72.010. Also, prohibited uses (like dispensaries) cannot be approved by variance. See § 17.09.040.

What findings must I meet to get a variance in unincorporated Tehama County?

You must show special property circumstances, accept conditions to avoid special privilege, demonstrate a hardship not self-created, avoid material detriment, and address General Plan compatibility. See § 17.72.020(A)–(E).

Can I reduce parking without a variance?

Often yes. The County can approve parking exceptions via a use permit if the design is of equal/greater excellence or if an existing facility lacks feasible space for all required parking. See the parking exception clause in § 17.08 (Off‑Street Parking) and the use-permit findings in § 17.70.040.

How are lot line adjustments handled in agricultural districts?

Lot line adjustments can be approved if they do not create more lots and keep parcels above thresholds—generally at least 80% of the district’s minimum parcel size (AG‑1/2/4/NR), and for AG‑3 at least 5 acres (non‑Williamson) or 40 acres (Williamson Act). See § 17.75.020–.030.

Who decides my variance and can I appeal?

The Planning Commission decides variances after a public hearing with notice, and written findings are required. Decisions are appealable to the Board of Supervisors. See § 17.72.030–.040, .060.

I have a legally nonconforming house—can I add into a setback?

Possibly. If the structure/property is determined legally nonconforming, the Planning Director may approve a setback adjustment for a proposed addition, without a variance, under § 17.08.030(B). Verify status with the County.

What if my lot is split by a zoning boundary?

The code allows the district boundary to be adjusted within a single lot via the variance process; you must still meet variance findings. See § 17.06.030(C).

Do variances override state building codes or fire codes?

No. A zoning variance does not waive separate state building or fire standards; you must comply with the California Building Standards Code. Not found in retrieved materials.
