Building permits, zoning and land rules in Shasta County, California

Yes. New construction and remodeling in unincorporated Shasta County require a building permit through the Resource Management Department's Building Division¹. California's Title 24 building standards apply in Shasta County, while local zoning, setbacks and property-line requirements remain local decisions¹³. The 2025 California Building Standards Code applies to permit applications filed on or after January 1, 2026¹⁴. Shasta County publishes valuation-based building-permit fees and charges regular plan review at 65% of the permit fee, subject to an $82.03 minimum; request a current project-specific estimate because the total can also include planning, fire, electrical, mechanical and plumbing charges^11,15. Owner-builder status concerns contractor licensing, not exemption from building permits or inspections⁹. Before issuance, the owner must personally read, initial, sign and return Shasta County's acknowledgment form and provide agency-accepted signature verification¹⁰. Hiring people other than California-licensed contractors on work totaling at least $500, including labor and materials, may make the owner an employer under state and federal law¹⁰.

The Shasta County Building Division is the first stop for building permits and inspections in the unincorporated county¹. Call (530) 225-5761 or visit 1855 Placer Street, Suite 102, Redding, CA 96001¹⁶. The Build Shasta portal lets registered public users and licensed contractors search parcels, submit limited online building permits and planning projects, pay fees and request inspections¹⁷. Inside Redding, the city Building Division issues building permits; Anderson handles its own building permits, including ADU applications^18,19. Septic permitting stays with Shasta County Environmental Health, including approval for private sewage-disposal systems in Anderson^3,20. County land-use questions go to the Planning Division at (530) 225-5532, 1855 Placer Street, Redding, CA 96001; septic questions go to Environmental Health at (530) 225-5787 at the same street address^4,21.

Yes. Shasta County zoning applies to unincorporated land; Redding and Anderson have their own zoning systems^2,22,23. City zoning does not transfer septic permitting away from Shasta County Environmental Health, whose approval is required for private sewage disposal in Anderson^3,20. The Planning Division maintains the County Zoning Plan and answers questions about zoning, land divisions and use permits²¹. Those standards are parcel- and district-specific, so ask Planning to identify the exact district and applicable conditions using the assessor's parcel number before relying on a listing description^2,21. In the Rural Residential (R-R) district the base minimum lot area is 2 acres, and in the Limited Residential (R-L) district it is 5 acres; new lots that abut timberland or agricultural land can face a larger minimum, and each building site must include contiguous acreage that is not steeper than 30 percent slope^5,6. Both districts carry 30-foot front, side and rear setbacks unless another section of the county code provides otherwise^5,6. We could not confirm a complete, current table for other districts, dwelling size, lot coverage or height; the Planning Division is the office to ask for a written parcel-specific answer²¹.

Shasta County Environmental Health administers onsite-wastewater permitting and requires a permit before a new or replacement septic tank and leach field is installed^3,4. The county application must include an accurate site plan, fees and soil-test data⁴. California's statewide onsite-wastewater policy allows locally tailored siting and design standards through approved Local Agency Management Programs²⁴. A properly functioning existing system may qualify for the policy's existing-system tier, but proximity to impaired waters or special local provisions can change the requirements; ask Environmental Health which rules apply before relying on an existing system²⁴. A local program cannot authorize a new or replacement onsite system where public sewer is available; Environmental Health should evaluate the policy's distance and replacement-cost exceptions for the parcel²⁵. Only 1.5% of mapped Shasta County soils lack severe limitations for a conventional drain field, so test before fixing the house location or assuming a standard system will work^4,26. Supplemental-treatment systems have separate operating-permit reporting and inspection paperwork; that requirement is not established for every conventional system³.

A tiny home on wheels classified as an RV is not intended as a permanent dwelling in California and, unless a local ordinance says otherwise, generally may be occupied only in a mobilehome park or special occupancy park⁸. We could not confirm a broader Shasta County option for long-term RV occupancy on vacant private land, so ask the Planning Division about the parcel and proposed use²¹. Shasta County limits residential occupancy of a mobile home or travel trailer at a building site to the site owner during construction of a one-family or two-family residence, and it requires the building permit and any use permit first¹. That temporary permit expires automatically when the building permit expires, when a certificate of occupancy is issued, or when the owner occupies the permanent home, whichever comes first¹. A recreational vehicle stored on a lot may not be connected to utilities or used for human habitation⁷. A site-constructed tiny home that does not fit another recognized housing category must comply with the California Building Standards Code and receive the applicable approval before occupancy; local land-use, fire and health requirements also apply⁸.

1. Give the Planning Division the assessor's parcel number and confirm zoning, allowed use and parcel-specific development standards^2,21.
2. Ask Environmental Health whether public sewer is available; if onsite treatment is eligible, submit the required site plan, fees and soil-test data^4,25.
3. If the parcel needs a well, obtain the well permit through Shasta County Environmental Health and use a licensed C-57 well-drilling contractor¹².
4. Settle access and grading: Caltrans approval applies to state-highway encroachments, and a grading permit is triggered by more than 250 cubic yards of earth movement or disturbance of 10,000 square feet or more^16,27.
5. Submit construction plans and the filing fee to the Building Division or use the online functions available through Build Shasta^16,17. Complete required inspections before final approval; owner-builders must first complete the county acknowledgment and signature verification^10,28.

Confirm zoning, legal access, flood exposure, water source and septic feasibility before making the purchase dependent on a buildable homesite^4,16,21. Shasta County receives about 43.1 inches of precipitation annually, yet severe drought occurs in 36.8% of years, so a water plan needs to work through dry periods as well as average ones²⁶. Shasta County Environmental Health is the local well-permitting agency, and California requires a permit before construction, modification or destruction by a licensed C-57 well-drilling contractor¹². Terrain can add cost: 74.6% of the county is wooded, while only 20% of its land has a slope of 15% or less²⁶. If a future split matters, California's Subdivision Map Act and local review address access, drainage, sanitary disposal and water availability²⁹. For carrying costs, the county's effective property-tax rate is about 0.7%, and the median annual bill is about $2,442²⁶.
