Shasta County Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

Shasta County regulates land use in its unincorporated areas through Title 17 — ZONING, which the code calls the county “zoning plan.” The zoning plan applies to development throughout the unincorporated portions of the county and implements the county general plan (§ 17.02.005; § 17.02.015; § 17.02.010) . Title 17 sets the county’s zone districts, combined/overlay districts, general development standards and procedure for permits, and it incorporates special maps such as zone maps and flood hazard maps (§ 17.02.025; § 17.02.030) .

How Shasta County’s code is organized

• Title name and scope: Title 17 is explicitly the county “zoning plan” and states its purposes and applicability to unincorporated county lands (§ 17.02.005; § 17.02.015; § 17.02.010) .
• Where to find the rules:
  • District definitions and permitted uses are laid out in the individual district chapters (the district listings and chapter layout are in § 17.02.025) .
  • Countywide development and site standards are grouped in Chapter 17.84 — General Development Standards (e.g., building-site rules, yard/setback measurement, zone walls) (§ 17.84.010–.020–.070) .
  • Off-street parking and loading standards live in Chapter 17.86; the chapter states when parking is required and the purpose of parking standards (§ 17.86.010–.030) .
  • Housing-specific accessory dwelling unit (ADU) rules are in § 17.88.132 and reference state ADU law (§ 65852.2) (§ 17.88.132) .
  • Procedural provisions for plan lines, zone amendments and related processes are in Chapter 17.92 (example: plan lines § 17.92.070; zoning plan amendments § 17.92.080) .

Zoning district families

The code establishes principal district families and several combine/overlay districts in § 17.02.025; the table that follows is the county’s list (all references: § 17.02.025) :

• Resource zone family (examples: A-1 — Limited agricultural, EA — Exclusive agricultural, TP — Timber production, TL — Timberland, MR — Mineral resource, HP — Habitat protection, OS — Open Space, F-1 — Designated Floodway) (§ 17.02.025) .
• Residential family (examples: R-L — Limited residential, R-R — Rural residential, R-1 — One‑family residential, R-2 — Two‑family residential, R-3 — Multiple‑family residential, MHP — Mobile home park, IR — Interim rural residential, ER — Existing residential) (§ 17.02.025) .
• Commercial family (examples: C-1 — Local convenience, C-2 — Community commercial, C-O — Office commercial, C-H — Highway commercial, C-R — Recreation commercial, C-M — Commercial‑light industrial, MU — Mixed use) (§ 17.02.025) .
• Industrial family (M-L — Light industrial, M — General industrial) (§ 17.02.025) .
• Special districts and tools: PF — Public facility, PD — Planned development, U — Unclassified, and combined districts such as AP, DR (Design Review), SP (Specific Plan) and ASP (Redding Airport Specific Plan) (§ 17.02.025) .

Practical note: the code applies particular development standards inside each district chapter, but cross‑cutting standards (yard measurement, landscaping, walls, lighting) are in Chapter 17.84 (§ 17.84.010–.070) .

Citywide development standards

• Setbacks and yards: Yards (front/side/rear) are governed by the general rules in § 17.84.020, and district chapters call those standards out and modify them where necessary (§ 17.84.020) . (See the county’s Development Standards.)
• Height and bulk: District chapters set maximum structural heights (for example, many commercial/industrial chapters include height caps and the district text repeatedly references exceptions in § 17.84.030) (§ 17.84.030; district chapters) .
• Lot size/coverage/FAR: Minimum lot area and related dimensional controls are set in district chapters (for example, M-L district minimum lot area and yard standards are in Chapter 17.56) and are applied together with Chapter 17.84 general rules (§ 17.56.050; § 17.84.010) .
• Parking: Off‑street parking is required for new and expanded uses; parking standards and when parking must be provided are set in Chapter 17.86 (§ 17.86.010–.030) . (See the county’s Parking.)
• Landscaping, screening and walls: County rules for landscaping and required zone walls appear in § 17.84.040 and § 17.84.070; for instance, commercial or industrial uses abutting residential zones require a 6‑ft masonry wall or berm unless exceptions apply (§ 17.84.070) . (See Landscaping and Screening.)
• Other standards and performance rules: District chapters contain on‑site performance standards for odors, vibration, glare and other nuisance conditions, and many district chapters refer applicants to the county development‑standards process (§ 17.16.060; district chapters) .

Links for design and discretionary processes such as design review live under the county’s Design Review and the overlay tools are under Overlay Districts.

Specific plans & overlays

• The code provides for combined/overlay districts such as SP — Specific Plan, DR — Design Review, SH — Scenic Highway, and ASP — Redding Airport Specific Plan; these are listed among the combined districts and applied in combination with principal districts (§ 17.02.025(C)) .
• The ASP district has its own uses, permit categories and minimum site standards when combined with other zones (see § 17.80.055–.080 for ASP‑related zoning permit, administrative permit and use permit rules and minimum landscaping/site rules) (§ 17.80.055; § 17.80.060; § 17.80.070; § 17.80.080) .
• Planned Development (PD) is the county’s mechanism for custom development standards; the PD framework requires timely filing of final development plans and provides for removal of the PD if conditions are not met (see Chapter 17.83 and the cross‑reference to zone amendment procedures, § 17.92.080) (§ 17.83; § 17.92.080) .

For historic resources and signage, the code uses overlay and chapter references; see the county menus for Historic Preservation and Signage.

Building permits & review — the typical path

1. Pre‑application / zone check: Confirm the property is in an appropriate district on the county zone maps (zone maps are maintained by the planning department; § 17.02.030) .
2. Determine permit type:
   • Some uses are permitted outright; others require a zoning permit, administrative permit, or use permit—the code lists ASP‑specific permit categories and many chapters cross‑reference these rules (see § 17.80.055–.070 for examples) (§ 17.80.055; § 17.80.060; § 17.80.070) .
   • Design review may be applied via the DR combine district or via district chapters that require a development plan (§ 17.02.025(C); district provisions) .
3. Submit plans & apply: District chapters frequently require the submission of a development/site plan showing how the applicable standards will be met (see district development‑plan language; e.g., C‑2 and other commercial district development plan requirements) (§ 17.46.*; district plan submittal language) .
4. Review & action:
   • Day‑to‑day ministerial zoning permits can be issued by the Director of Resource Management; the director may refer more discretionary matters to the planning commission and appeals follow the code’s appeal procedures (§ 17.92.*; procedural snippets on director referral and appeals) .
   • Parking, landscaping and off‑street improvements must be addressed before final inspection/occupancy per Chapter 17.86 and the development‑standards cross references (§ 17.86.030) .
5. Time limits & revocation: Zoning permits are revocable and include time limits for commencement of approved activity (see the zoning‑permit rules for revocation and expiration language) (§ 17.92.*) .
6. Building code: In addition to Title 17 land‑use approvals, construction must comply with the state building-code regime (the California Building Standards Code/Title 24). Refer to county building‑permit processes for building permits and inspections. (See the county’s California Building Standards Code menu.)

If you are uncertain about whether a project is ministerial or discretionary, consult the planning division early—the code explicitly allows the director to refer matters to the planning commission when substantial discretion is required (§ 17.92.*) .

State housing law in Shasta County

• Accessory dwelling units (ADUs/JADUs): The county’s ADU rules are codified at § 17.88.132; the section states intent to comply with Government Code § 65852.2 and sets local applicability (ADUs allowed in zones permitting a one‑family residence, one ADU per lot, rental restrictions, etc.) (§ 17.88.132) . (See state ADU guidance: California ADU law.)
• Density bonus: The code references local density bonus provisions (for example, a 25% density bonus is referenced in § 17.83.070 and § 17.62.030) and links those local bonus rules to PD applications (§ 17.83.070; § 17.62.030) .
• SB 9 / ministerial duplex and lot‑split reforms: The Title 17 excerpts retrieved do not explicitly show local amendments or objective standards implementing SB 9. Verify with the planning department whether the county has adopted objective standards or ministerial SB 9 procedures (Not found in retrieved materials).
• Rent control / tenant protections: Title 17 is a land‑use/zoning ordinance and the retrieved materials do not show any county rent‑control ordinance in Title 17 (Not found in retrieved materials). Confirm with county administration or county code search for ordinances outside Title 17.

State housing statutes can preempt or limit local rules; because the ADU section explicitly references Government Code § 65852.2, the county intends to align its ADU rules with state law (§ 17.88.132) . For other state housing mandates (SB 9, density bonus implementation, etc.), check with the planning division for local objective‑standard updates.

Information Gaps / What to verify with the county

• Local implementation of SB 9 (ministerial approval for duplexes and lot splits) is not visible in the supplied Title 17 excerpts — confirm whether the county has adopted objective SB 9 standards or streamlined checklists (Not found in retrieved materials).
• Detailed procedural section numbers for zoning permits, appeals, and exact timeframes and fees require looking at the full Chapter 17.92 and the planning division permit handouts (some procedural snippets appear in the files, but readers should request the planning counter handouts to confirm current filing fees and submittal checklists) (§ 17.92.*) .
• Any city‑level regulations do not apply to unincorporated county lands; verify whether properties are in unincorporated territory via the county zone maps (§ 17.02.015; § 17.02.030) .
