Do you need a building permit 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, while zoning, setbacks and property-line rules remain local matters13. The 2025 California Building Standards Code applies to permit applications filed on or after January 1, 202614. Shasta County publishes valuation-based permit fees and charges regular plan review at 65% of the permit fee, subject to an $82.03 minimum11. Individual permit records show that a project's total can also include planning, fire, electrical, mechanical and plumbing charges, so request a project-specific estimate rather than relying on one permit's total15. Owner-builders still need a permit: the property owner must personally complete the county acknowledgment and provide acceptable signature verification before issuance910.
Who is the Shasta County building department, and how do you reach it?
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 960017. 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 inspections16. County permit conditions can require work to be completed before the Building Division's final inspection, and unpermitted additions can have to be permitted before a certificate of occupancy is issued; the cited examples are project-specific, so ask the division what applies to your permit1718. Land-use and zoning questions belong with the Planning Division at (530) 225-5532, 1855 Placer Street, Redding, CA 9600119. Septic questions go to Environmental Health at (530) 225-5787 at the same street address5.
Does Shasta County have zoning?
Yes. Shasta County maintains a zoning system for the unincorporated county, while incorporated areas such as the City of Redding are represented separately in county mapping263. The Planning Division maintains the County Zoning Plan and answers questions about zoning, land divisions and use permits19. California gives counties authority to regulate uses, building height, lot coverage, yards and setbacks through local zoning20. 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 description619. We could not confirm a complete, current countywide table for ordinary minimum lot size, dwelling size, setbacks, lot coverage or height; the Planning Division is the office to ask for a written parcel-specific answer19.
How do septic permits work in Shasta County?
Shasta County Environmental Health requires a permit before a new or replacement septic tank and leach field is installed45. The county says the application must include an accurate site plan, fees and soil-test data5. California's statewide onsite-wastewater policy assigns permitting to local agencies under state and regional oversight, and Shasta County Environmental Health administers the county program2122. Start the septic review before fixing the house location because only 1.5% of mapped county soils lack severe limitations for a conventional drain field23. That countywide soil statistic does not decide an individual site, but it makes early testing and a realistic allowance for a nonstandard design especially important235. Supplemental-treatment systems have their own operating-permit reporting and inspection paperwork; that requirement is not established for every conventional system2425.
Can you live in an RV or tiny home on your land in Shasta County?
We could not confirm a general Shasta County rule allowing long-term RV occupancy on vacant private land, so ask the Planning Division about the parcel and proposed use before purchase19. Shasta County does confirm a narrower construction option: a mobile unit may serve as a temporary residence while the principal home is built if the owner obtains a temporary mobile-unit permit attached to a valid residential building permit7. If that unit is an RV, it may remain stored on the property, but it must be disconnected from utilities within 15 days and removed within 60 days after approval of the permanent residence's building permit7. Camping is expressly permitted in the Timber Production district only when it involves no permanent land improvement and does not materially interfere with the district's primary use; that narrow rule is not countywide permission for residential RV use26. A tiny home must fit a recognized California housing category and meet the rules for that category8. County records show that Shasta County has permitted both a conventional accessory dwelling unit and a manufactured-home accessory dwelling unit on a permanent foundation, but those parcel-specific approvals do not guarantee approval elsewhere272829.
Building a home in Shasta County: the steps, in order
First, give the Planning Division the assessor's parcel number and confirm zoning, allowed use and parcel-specific development standards196. Second, have Environmental Health determine the septic path and submit the required site plan, fees and soil-test data5. Third, settle access and grading: county review applies to projects accessing a county road, Caltrans approval applies to encroachments on a state highway, and a grading permit is triggered by more than 250 cubic yards of earth movement or disturbance of 10,000 square feet or more730. Fourth, submit construction plans and the filing fee to the Building Division or use the online functions available through Build Shasta716. Fifth, complete every required inspection and resolve unpermitted work before seeking final approval or occupancy; county use-permit conditions illustrate both requirements, although the exact conditions vary by project1718. An owner-builder must personally sign the county acknowledgment and provide acceptable signature verification before permit issuance10.
What should you check before buying land in Shasta County?
Confirm zoning, legal access, flood exposure, water source and septic feasibility before making the purchase dependent on a buildable homesite1975. 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 ones3132. California requires a permit from the applicable local environmental health agency or water district before a water well is constructed, modified or destroyed12. Terrain can add cost: 74.6% of the county is wooded, while only 20% of its land has a slope of 15% or less3334. If a future split matters, California's Subdivision Map Act and local review address access, drainage, sanitary disposal and water availability35. For carrying costs, the county's effective property-tax rate is about 0.7%, and the median annual bill is about $2,4423637.
Watch-outs
- Do not treat a parcel's county zoning label as the full answer: district conditions and development standards still need parcel-specific confirmation from the Shasta County Planning Division619.
- The construction-period mobile-unit permit and the narrow camping allowance in the Timber Production district do not confirm long-term RV living on vacant land elsewhere726.
- A state-highway driveway needs Caltrans encroachment approval, while access from a county road goes through county review730.
- Shasta County's mapped soils rarely rate free of severe conventional-drain-field limitations, so complete soil testing before committing to a house site235.
