Shasta County — Variances and Exceptions

Q: What is the basic test the County uses to grant a variance in unincorporated Shasta County?

Shasta County requires the three classic findings: (1) special circumstances of the parcel (size, shape, topography, location, surroundings) that cause the strict application to deprive the property of privileges enjoyed by others; (2) the variance is necessary to preserve substantial property rights of the applicant; and (3) the variance will not adversely affect health and safety or be materially detrimental to neighbors or public welfare — see § 17.92.010.A.1–3 .

Q: Are ADU relaxed standards handled as variances or exceptions?

For ADUs the code provides exceptions to certain development standards (size, lot acreage, location, parking, garages) that are available via an administrative permit (Director-level) pursuant to § 17.92.050 ; those exceptions require specific findings by the Director and are not the same as a Planning Commission variance under § 17.92.010 . Verify whether your relief request is an ADU exception or a general variance.

Q: What is the appeal process and how long do I have to appeal a Planning Commission variance decision?

An interested person has five (5) calendar days after the Planning Commission decision to file a notice of appeal with the Clerk of the Board of Supervisors; the Board holds a de novo review on the record and has final authority to affirm, reverse, modify or remand the decision ( § 17.92.030.A–E ).

Q: If my property is in the Whiskeytown NRA (NRA‑WI or NRA‑WII), is there anything extra I must do?

Yes. Variances/exceptions in NRA‑WI and NRA‑WII may trigger consultation/notice to the Secretary of the Interior ; the County must provide notice at least 30 days before the hearing if the property is “improved property” and the Secretary may advise whether the intended use will subject the property to acquisition — see § 17.20.050.B–C .

Q: If my variance is granted and I’m in a flood area, who keeps the record and reports it?

The floodplain administrator is required to maintain a permanent record of all flood-related variance actions and report such variances in the biennial report to the relevant federal agencies (FEMA). See the record‑keeping provisions in § 17.70.060.C and related flood chapters.

Overview

This page explains how the Shasta County zoning/planning ordinance treats variances and exceptions for properties in unincorporated areas of Shasta County. It summarizes who decides, the findings required, how floodplain and National Recreation Area districts are treated differently, and which procedures (hearings, appeals, expiration, revocation) control approvals. For general background on county planning and where these rules sit in the local framework see the Shasta County zoning & planning overview and the primary Shasta County Zoning pages.

Core rules that apply countywide

Who decides: Variances and exceptions are processed by the Planning Department and decided by the Planning Commission (with appeals to the Board of Supervisors) under the procedures of § 17.92.010 and § 17.92.030. § 17.92.010 sets the application, findings, hearing and staff-report requirements.
Required findings: The applicant must demonstrate (among other points) (1) special circumstances of the parcel (size, shape, topography, location, surroundings) that make strict application deprive the property of privileges of other lots in the same zone district; (2) the variance is necessary for preservation and enjoyment of substantial property rights; and (3) the variance will not adversely affect health and safety or be materially detrimental to the public welfare — all set out in § 17.92.010.A.1–3.
Legislative limit: Local variances are only authorized where the variance would be permissible under state law (explicitly tied to Government Code § 65906) and the County's local standards for variances. See § 17.92 (standards governing variances).
Procedure & notices: Applications must be complete (fees and submittals), are routed to staff and subject to CEQA review, followed by a public hearing before the Planning Commission; decisions are made by resolution describing conditions and findings (§ 17.92.010.C–F).
Appeals: Any interested person may appeal a Planning Commission decision to the Board of Supervisors within five (5) calendar days of the decision; the Board reviews the record and can affirm, reverse, modify, or remand the decision (§ 17.92.030).
Expiration/Revocation & Permit Issuance: A variance/use permit expires if not actively commenced within two (2) years (or other timeframes specified); the Planning Commission may revoke for noncompliance or other specific grounds; no building permit for work that requires a variance will issue until appeal windows are exhausted or appeals resolved (§ 17.92.040 and § 17.92.010.F–I).

District-by-district notes (where the ordinance supplies district-specific variance/exception rules)

Notes: Variances and exceptions are generally administered under the countywide procedures above; the subsections below call out district-level special rules that change findings, required consultations, or recording obligations. All district names below are for unincorporated areas only and are written exactly as in the ordinance.

All zones — general application

Purpose: Provide relief from literal enforcement of dimensional/development standards when the strict rule would create unnecessary hardship or practical difficulty. The general test and procedure are in § 17.92.010. Typical permitted uses remain those listed in each zone; a variance cannot authorize a use not expressly allowed by the zone regulations (§ 17.92.010.F–G).

Key dimensional standards (examples):

Application contents and findings: § 17.92.010.A.1–3 (special circumstances, necessity, no adverse effects).
Hearing & notice rules: publication and mailed notice per § 17.92.010.E.
Appeal window: five (5) calendar days to appeal to Board of Supervisors (§ 17.92.030.A).

Designated Floodway (F-1) — special floodplain variance rules

Purpose: Protect life, property and riparian environments within the floodway; the F‑1 district carries extra flood rules. See § 17.22.010–020 for the district purpose and permitted uses.

How variances differ:

Floodplain variances are handled under the flood provisions in Chapter 17.70 (floodplain rules) and tied to the Building Code flood appendix. The County limits variances for flood elevations and requires strict findings that consider technical flood factors; variances are rare and may require recording of a notice in the chain of title when a variance allows construction below base flood elevation (§ 17.70.060.B, § 17.70.060.D).
Time limits: flood-related permits/variances become invalid if work does not commence within 180 days or is suspended/abandoned for 180 days; the floodplain administrator may grant extensions in writing (§ 17.70.060.D).
Documentation & reporting: the floodplain administrator must maintain records of variances and report to FEMA; specific technical criteria (hazard, sediment transport, accessibility, cost of services) must be considered (§ 17.70.060.A & recordkeeping sections).

(State-level flood construction standards (Appendix G / CBC) apply in parallel — see California Building Standards Code.) California Building Standards Code

NRA — National Recreation Area districts: NRA‑WI, NRA‑WII (Whiskeytown) and NRA‑S

Purpose: Protect recreation/forest/resort character within Whiskeytown/Shasta units. See § 17.20 (NRA‑WI & NRA‑WII) and § 17.18 (NRA‑S) for purposes and permitted uses.

How variances/exceptions differ:

Variances and exceptions in NRA‑WI and NRA‑WII are processed under the general variance rules but carry a special requirement: the County must notify and may consult the Secretary of the Interior before a hearing; a variance that causes property not to conform to NRA standards may reinstate the Secretary's authority to acquire improved property — see § 17.20.050.A–C.
NRA‑S has similar variance limitations and conditions in § 17.18.060; consult those subsections before assuming a standard county variance will be sufficient.

ADU-related exceptions (Accessory Dwelling Units)

ADU development standards in § 17.88.132 permit certain exceptions (size, minimum lot acreage, location, parking, garages) if an administrative permit is approved under § 17.92.050 and specific findings are made by the Director (e.g., lot constraints, no health/safety hazard). These exceptions are administrative (Director-level) rather than Planning Commission variances. See § 17.88.132.14 and § 17.92.050.

Risks & Ambiguities

Issue	Why it matters	What to verify
Floodplain variance recording and insurance premium warning	Flood variances permitting construction below base flood level require a recorded notice and typically increase flood insurance premiums; failure to record or accept the warning is not allowed.	Confirm the floodplain-specific requirements and recorded notice language in § 17.70.060.B–C; consult the floodplain administrator.
Time limits and extensions (180 days / 2 years)	Different programs use different expiration clocks: flood permits use 180 days; zone variances/permits lapse if not commenced within 2 years. Missing these deadlines can void approvals.	Verify whether § 17.70.060.D (flood) or § 17.92.040.D (variance/use permit expiration) applies.
Authority to grant “exceptions” vs. “variances”	Some standards (e.g., ADUs, specific locational rules) are handled as administrative exceptions rather than Planning Commission variances — different findings and review bodies.	Confirm whether relief needed is an administrative exception under § 17.88.132.14 or a variance under § 17.92.010.
NRA districts — Secretary of the Interior consultation	For Whiskeytown-area districts, failure to consult the Secretary of the Interior may cause the Secretary’s acquisition authority to be reinstated or delay the hearing.	Verify the notice/consultation timeline in § 17.20.050.B–C and notify the Secretary 30 days before the hearing if necessary.
Whether a variance would authorize a new use	County code forbids variances that create uses not authorized in the zone — risk of denial if applicant seeks an unlisted use.	Check the zone’s permitted uses and confirm that the variance request does not attempt to legalize a prohibited use (§ 17.92.010.G).

Plain‑English Summary

If a strict zoning rule on your unincorporated Shasta County property causes a practical hardship, you can apply for a variance under County rules; you must show special property circumstances, that the variance is necessary to protect your property rights, and that it won't harm neighbors or public welfare. Floodplain areas, Whiskeytown/NRA districts, and ADU-related exceptions have extra steps (recorded notices, Secretary of the Interior consultation, or director-level administrative findings) — check § 17.92.010, § 17.70.060, and § 17.88.132 and verify with County staff before you proceed.

Frequently asked questions

What is the basic test the County uses to grant a variance in unincorporated Shasta County?

Shasta County requires the three classic findings: (1) special circumstances of the parcel (size, shape, topography, location, surroundings) that cause the strict application to deprive the property of privileges enjoyed by others; (2) the variance is necessary to preserve substantial property rights of the applicant; and (3) the variance will not adversely affect health and safety or be materially detrimental to neighbors or public welfare — see § 17.92.010.A.1–3.

How long before a granted variance expires if I don’t start construction?

A variance or use permit generally expires if the authorized activity is not actively and substantially commenced within two (2) years of approval, unless extended by the Director/Planning Commission in accordance with § 17.92.040.D. For flood‑related variances/permits, a separate 180‑day commencement/abandonment rule applies (§ 17.70.060.D).

Can I get a variance to build below base flood elevation in a floodway?

Possibly, but flood variances are rare and tightly constrained: the County’s flood provisions require specific technical findings (hazards, sediment transport, safety, alternatives) and mandate that the applicant receive a written notice that building below base flood elevation increases flood insurance premiums and risks; the notice must be recorded in the chain of title where applicable (§ 17.70.060.A–C).

Are ADU relaxed standards handled as variances or exceptions?

For ADUs the code provides exceptions to certain development standards (size, lot acreage, location, parking, garages) that are available via an administrative permit (Director-level) pursuant to § 17.92.050; those exceptions require specific findings by the Director and are not the same as a Planning Commission variance under § 17.92.010. Verify whether your relief request is an ADU exception or a general variance.

What is the appeal process and how long do I have to appeal a Planning Commission variance decision?

An interested person has five (5) calendar days after the Planning Commission decision to file a notice of appeal with the Clerk of the Board of Supervisors; the Board holds a de novo review on the record and has final authority to affirm, reverse, modify or remand the decision (§ 17.92.030.A–E).

If my property is in the Whiskeytown NRA (NRA‑WI or NRA‑WII), is there anything extra I must do?

Yes. Variances/exceptions in NRA‑WI and NRA‑WII may trigger consultation/notice to the Secretary of the Interior; the County must provide notice at least 30 days before the hearing if the property is “improved property” and the Secretary may advise whether the intended use will subject the property to acquisition — see § 17.20.050.B–C.

Can a variance allow a use that is not allowed in my zone?

No. The County code explicitly states that no variance shall authorize a use or activity not expressly authorized by the zone district regulations; variances are intended to modify application of regulations, not to create new allowed uses (§ 17.92.010.G).

Do I need CEQA review for my variance application?

Yes. All variance applications are reviewed for compliance with the California Environmental Quality Act under the County’s established procedures as part of the application process (§ 17.92.010.C).

What happens if I don’t respond to an incomplete application request?

If the County mails an incompleteness notice and the applicant fails to respond within thirty (30) days, the application is deemed abandoned and no further action will be taken (§ 17.92.010.B).

If my variance is granted and I’m in a flood area, who keeps the record and reports it?

The floodplain administrator is required to maintain a permanent record of all flood-related variance actions and report such variances in the biennial report to the relevant federal agencies (FEMA). See the record‑keeping provisions in § 17.70.060.C and related flood chapters.
