Shasta County — Land Use

Last reviewed: July 3, 2026

Overview

This page explains how land use is regulated in the unincorporated areas of Shasta County under Title 17 (the local zoning plan). It summarizes what uses are permitted or require discretionary approval, the main district-by-district rules you will actually need to check, and where those rules live in the ordinance (with exact § citations). Where the code excerpts retrieved do not establish an item, the page says so and recommends verification with the County.

For general procedural topics referenced below (site development standards, parking, overlays, and design review) see the county guides: Shasta County Development Standards, Shasta County Parking, Shasta County Overlay Districts, and Shasta County Design Review.

District-by-district summary (key permitted uses & development rules)

Notes on reading this section: every district name below is the actual Title 17 district used in the Shasta County Zoning Plan; the short bullet summaries synthesize the ordinance (do not replace reading the cited §). Where numeric standards are listed the controlling code § is cited.

R-1 — One‑Family Residential

• Purpose: intended for “fully serviced, urban-sized lots used exclusively for one-family residences and selected related uses.” § 17.30.010 .
• Typical permitted uses: one‑family residence, foundation-installed manufactured homes, supportive housing, transitional housing, one ADU (when a primary dwelling exists), small family day care, residential care (≤6 residents). § 17.30.020 .
• Uses requiring permits: home occupations, guest houses (zoning permit) and larger home‑businesses, B&Bs, large family day care (administrative or use permits) — see § 17.30.025–.040 .
• Development standards (setbacks/height): the R‑1 permitted‑uses section lists uses; specific yard/height figures are established elsewhere in Title 17 for applicable projects or in Chapter 17.84/17.86—search parcel-specific standards or verify with the County. (Specific R‑1 setback/height numbers were Not found in retrieved materials for a single consolidated R‑1 yard table in the retrieved excerpts.) Verify with the jurisdiction; see § 17.30.020 for uses. .

R-R — Rural Residential

• Purpose: rural residential living in/near rural communities; consistent with RA general plan designation. § 17.26.010 .
• Typical permitted uses: one‑family residence, agriculture (if lot ≥ 1 acre with animal limits defined), supportive/transitional housing and accessory ADU allowances. § 17.26.020 and § 17.26.060(A) .
• Key standards: where applied without community plan exceptions, maximum densities vary by slope and location (e.g., where slope >30% max density = 1 dwelling / 10 acres; where slope ≤30% common standard is 1 dwelling / 2 acres, with community exceptions) and front/side/rear yards = 30 ft. § 17.26.060 (A)(1), (B) .
• Other: water and sewage capacity must be demonstrated for new building sites; see § 17.26.060(A)(1)(c–d) .

R‑L — Limited Residential

• Purpose & uses: rural-living with large-lot emphasis; permitted uses and density rules similar to R‑R but with larger minimum parcel sizes. See Chapter 17.24 for detailed permitted uses and density formulas. § 17.24.020–.060 .
• Key standard examples: max density for slopes >30% = 1 du / 80 acres; for ≤30% commonly 1 du / 5 acres (see the chapter for exact mapping). § 17.24.060 .

A‑1 — Limited Agriculture and EA — Exclusive Agriculture

• Typical permitted uses: agricultural production and accessory structures; many agricultural accessory buildings are allowed where the zone permits agriculture by right and the parcel meets applicable minimum acreage. See general accessory-agri rules in Chapter 17.88 and zone chapters. § 17.88 provisions and A‑1/Ea chapter references (see Chapter 17.04 and 17.06 in Title 17).

TL — Timberland and TP — Timber Production

• Purpose: protect timber management and productive timberlands. § 17.10.010 (TL) and § 17.08.010 (TP) (chapter headings).
• Permitted uses in TL/TP include timber management and related incidental activities; many uses require a use permit in TL or TP (examples listed in § 17.10.040 and § 17.08.030). § 17.10.040 and § 17.08.030 .
• TL site standards example: front/side/rear yards = 30 ft and specific minimum lot sizes tied to Table 17.08.040 which sets minimum parcel sizes by Timber Site Classification (e.g., Class I = 40 acres, Class II = 60 acres, Class III = 80 acres, IV/V = 80 acres). § 17.10.060; Table 17.08.040 .

MU — Mixed Use

• Purpose: allows a variety of residential, commercial and light industrial uses that do not generate odor/noise/visual impacts; site-specific performance standards address conflicts. § 17.54.010 .
• Permitted uses: agriculture (on parcels ≥ 1 acre with animal limits), sales of products grown on‑site; residential uses allowed as accessory or per zoning permit rules. § 17.54.020–.025 .

C‑O, C‑2, C‑M — Commercial / Office / Mixed Commercial

• C‑O (Office Commercial) is intended for professional, business and medical offices; permitted uses listed in § 17.46.020. § 17.46.020 .
• C‑2/C‑M chapters contain lists of retail, service and light commercial uses; check specific chapter for use-by-use permit lists and development plan requirements. Example: C‑2 has a required development plan for mixed use locations; see relevant district section. § 17.XX (see chapter headings in Title 17). Not every numeric C‑2 figure was in the retrieved excerpts — verify parcel specifics. .

M‑L / M — Industrial / Light Industrial

• M‑L (Light Manufacturing) permitted uses and site development standards: minimum lot area = 20,000 sq ft, min width = 80 ft, yard standards such as front = 10 ft, and maximum height = 45 ft (with special limits where abutting residential districts). § 17.56.050 (A–D) .
• Parking, landscaping, lighting and trash storage standards reference Chapter 17.84 and Chapter 17.86 for cross‑references. § 17.56.050 (E–K) .

OS — Open Space

• Permitted uses: forest management, low‑intensity recreation and agriculture. § 17.16.020 .
• Residential uses are tightly constrained; one‑family residences allowed by administrative permit on parcels ≥ 40 acres, and accessory housing (ADU) is conditionally allowed in some circumstances. § 17.16.030 .

U — Unclassified (holding)

• Purpose: temporary holding zone until a principal district is applied; allows limited residential and accessory uses while the property remains unclassified. Example permitted uses: one‑family residence, agricultural and timber uses per applicable district, one ADU where a primary dwelling exists. § 17.64.010–.025 .

Special districts & overlays

• IMR (Important Mineral Resource), T (Mobile Home combining), PD (Planned Development) and other combining districts modify principal district rules. Example: IMR imposes mitigation and minimum lot area rules and cannot be combined with many residential zones. § 17.72.020–.040 . PD is governed by Chapter 17.62 (final development plans, time limits, amendments). § 17.62.070–.100 .
• Overlay-specific provisions (airport ASP, IMR, habitat protection) will add conditions to the underlying district; see the overlay chapter for the overlay applied to your parcel. For overlay guidance see Shasta County Overlay Districts.

Quick decision table — common, decision‑relevant items

(Always confirm the exact parcel combination of principal + overlay districts — verify with the jurisdiction; overlays change permit requirements: see specific overlay chapters.)

How uses are classified and review types

• Uses are listed in each district as permitted outright, permitted with a zoning permit, permitted with an administrative permit, or permitted only with a use permit; see the head of each district for the category (e.g., § 17.30.020–.040 for R‑1). § 17.30.020–.040 .
• Some topic‑specific uses are governed centrally in Chapter 17.88 (e.g., accessory agricultural buildings, wineries, electric vehicle charging, public uses). For example, electric vehicle charging stations are permitted in all districts if they do not cause a specific adverse impact (and otherwise may require a use permit). See § 17.88.080. § 17.88.080 .
• Special use tables exist (e.g., wineries and winery events in Table 17.88.300) and define where boutique/small/medium/large wineries are allowed and what permit level is required. Table 17.88.300 .

Checklist — what an applicant must satisfy (unincorporated Shasta County)

• Confirm the parcel’s current zoning and any overlay districts (county zoning maps / planning staff). § 17.02.015 .
• Identify whether your proposed use is listed as permitted, zoning permit, administrative permit, or use permit in the applicable district chapter (example: § 17.30.020 for R‑1). .
• Meet district site development standards (minimum lot area, setbacks, heights) listed in the district chapter (e.g., § 17.26.060 for R‑R; § 17.56.050 for M‑L). See Shasta County Development Standards. .
• Comply with parking standards in Chapter 17.86 and provide required spaces/dimensions; consult Shasta County Parking. (See district cross‑references, e.g., § 17.56.050(G).) .
• If subject to an overlay (IMR, ASP, HP, etc.) satisfy overlay conditions (e.g., IMR mitigation, airport plan conflicts). See overlay chapter(s) and Shasta County Overlay Districts. § 17.72.020–.040; § 17.80.055–.080 .
• If your parcel is in a PD district, submit a final development plan by the timeline in § 17.62.070 and follow PD-specific conditions. § 17.62.070–.080 .
• Check design/concept requirements if design review may apply; consult Shasta County Design Review. If signage, landscaping or nonconforming issues arise, follow Shasta County Signage, Shasta County Landscaping and Screening, and Shasta County Nonconforming Uses.
• If seeking an exception or relief, confirm variance or use‑permit submittal requirements in Chapter 17.92 and consult Shasta County Variances and Exceptions. § 17.92.010 .
• If proposing an ADU, confirm conformance with local ADU provisions listed in Title 17 (ADU cross‑references are included in several districts) and state ADU law guidance: California ADU law. See ADU mentions: § 17.30.020(F); § 17.64.020(F)(4); § 17.16.030(H). .
• Prepare site plans and technical studies (water/septic evidence where required for density) as district chapters require (e.g., § 17.26.060(A)(1)(c–d)). .

Risks & Ambiguities

Plain‑English summary

For unincorporated land in Shasta County you must read the Title 17 district that covers your parcel: the district lists what you can build outright, what needs a simple zoning or administrative permit, and what needs a discretionary use permit. Important standards—minimum lot sizes, setbacks and height limits—are stated in each district chapter (for example R‑R yards are 30 ft and many resource districts tie parcel size to timber site class). Always verify your parcel’s principal district and any overlays because those change what’s allowed; see the cited §§ below for the exact language. § 17.26.060; § 17.30.020; Table 17.08.040
