Do you need a building permit in Tehama County, California?

Tehama County Building & Safety processes building permits for houses and related residential construction in unincorporated Tehama County1. Inside Red Bluff, city approval governs building permits; inside the City of Tehama, the county Building Department issues building permits under city-adopted codes1213. The county septic-permit rule below applies to unincorporated land; Red Bluff separately authorizes city onsite-sewage regulations314. Tehama County lists Ordinance #2150 adopting the 2025 building-code cycle15. The published plot-plan review fee is $101.00, with other fees depending on the application16. Building-permit applications expire after 180 days; issued building permits generally require final inspection approval and any required certificate of occupancy within two years, subject to code exceptions1718. California's owner-builder exemption concerns contractor licensure, while the owner remains responsible for building permits and inspections; personally performed work or work by wage-paid employees must not be intended for sale, and owners cannot do well-drilling work themselves6.

Who is the Tehama County building department, and how do you reach them?

The Tehama County Building & Safety Department, at 444 Oak Street, Room H in Red Bluff, reviews plans, issues building permits and inspects construction in unincorporated Tehama County19. Call (530) 527-7002, or apply online through the county's permitting portal at tehamacountyca.viewpointcloud.com19. If you are building a house, have an approved plot plan, a complete set of building plans, energy calculations, truss calculations, a modified soils test, structural calculations if applicable, solar plans and a Manual J report, and a flood elevation certificate if applicable ready when you apply1. After the building permit issues, required inspections include the foundation, underfloor, roof sheathing and framing stages, plus County Fire, County Road/CalTrans and Environmental Health clearances before the final inspection20.

Does Tehama County have zoning?

Tehama County zoning applies to unincorporated land; Red Bluff, Corning and the City of Tehama have city zoning2212223. Tehama County Environmental Health handles septic permits in the unincorporated area3. County residential minimum lot areas are 10,500 square feet in RE, 5,000 in R-1 and 6,000 in R-2 through R-4, with 60-foot width required in R-1 through R-4; B combining-district designations can change lot-area requirements4. R-1 through R-4 list 20-foot front and rear setbacks and 6-foot side setbacks; RE lists the same distances but has an unresolved front-setback qualification, so ask Planning before siting an RE home242526. Maximum height is 35 feet in RE through R-3 and 65 feet in R-4, with stricter H combining-district limits prevailing27. Maximum lot coverage ranges from 40% in RE and R-1 to 60% in R-428. PD use permits and specific plans can set different standards; call Planning at (530) 527-2200 with the address or APN2426. Tehama County has no formally codified minimum dwelling size but typically applies 350 square feet7.

How do septic permits work in Tehama County?

Tehama County Environmental Health requires a permit before anyone builds, repairs or alters an onsite sewage system in unincorporated Tehama County3. Starting work without that permit generally triggers triple the permit fee if the work is later approved, and the installer must keep the permit onsite throughout construction or repair29. Reach Environmental Health at (530) 527-8020, 633 Washington Street, Room 36, Red Bluff30. Public sewer may be considered unavailable when it is more than 200 feet from the proposed building on an abutting lot or premises29. Only 1.9% of Tehama County soils rate free of severe limitations for a conventional drain field, so obtain a site evaluation before assuming a standard system will work9. Connection to an available public sewer generally takes precedence over a new septic system, with limited exceptions for certain existing dwellings or accessory structures; inadequate lot area or soils can stop both septic and building permits unless engineering and test data support reevaluation3. Cesspools are not authorized and must be replaced when discovered through specified county processes31.

Can you live in an RV or tiny home on your land in Tehama County?

Under California's default rule, an RV is not meant for permanent occupancy and, unless a local ordinance says otherwise, may be occupied only in a mobilehome park or special occupancy park32. We could not confirm a general Tehama County rule for temporary camping on private land, so ask Planning about the parcel and proposed duration26. A tiny home must qualify as an approved housing type, such as a code-compliant dwelling, manufactured home, factory-built home, RV or park trailer; otherwise it cannot legally be occupied33. A temporary Park Fire ordinance allows a displaced resident one RV, movable tiny house or qualifying manufactured home per premises, subject to permits, utilities, owner consent and setbacks343536. The county cannot permit installation of a manufactured home made before 2014 under that exception, which expires three years after its effective date unless extended or changed36. An accessory dwelling unit is a legal route to a second home: a single-family residence may have up to one ADU and one junior ADU, the Planning Department must verify the property allows one, and every ADU needs a building permit; short-term vacation rentals of less than 31 days and mobile homes do not qualify as ADUs37.

What are the steps to build a home in Tehama County?

  1. Call the Planning Department at (530) 527-2200 with your property address or APN to confirm the zoning district, permitted use, setbacks, lot coverage and any combining district before you design or site a home26.
  2. If you will divide the land, take the concept to Planning first because land divisions undergo county and state map review; subdivisions creating parcels under one acre generally require community sewer service5.
  3. Gather the approved plot plan, complete building plans, energy and truss calculations, soils test, any required structural calculations, solar plans, Manual J report and any required flood elevation certificate, then apply online or at Building & Safety119.
  4. Apply to Tehama County Environmental Health for an OWTS permit if the site will not connect to public sewer2930.
  5. If the driveway enters a state highway right of way, obtain a Caltrans encroachment permit38.
  6. After the building permit issues, schedule each required inspection and obtain the county clearances before final inspection20.

What should you check before buying land in Tehama County?

Lot splits: unincorporated Tehama County generally requires a tentative major-subdivision map for five or more lots; a minor parcel map can create up to four lots plus a remainder only when the remainder is not intended for sale, lease or financing5. Subdivisions creating parcels under one acre require community sanitary sewer service and a public operating entity unless the approving authority grants a waiver after consulting the Regional Water Quality Control Board; seepage pits are unsuitable for newly created lots5. Water: California requires local well permits before construction, modification or destruction and a licensed well-drilling contractor39. Tehama County separately regulates groundwater extraction for off-parcel use, with an exception for contiguous parcels under the same ownership; ask Environmental Health how the groundwater and well-construction approvals apply to your project4030. Flood: floodway development requires an engineer's certification of no increase in base flood elevation41. Rentals: unincorporated Tehama County requires a Short-Term Rental permit and charges 8% transient occupancy tax on stays of 30 days or less42. Taxes: the effective property tax rate is about 0.6%, with a median annual bill near $1,9961110.

Watch-outs

  • Tehama County agricultural-exempt buildings cannot be homes, workplaces or commercial buildings: parcels of 1 to 10 acres allow up to 600 square feet and 15 feet in height, while parcels over 10 acres allow up to 12,000 square feet and 25 feet in height8.
  • Tehama County's agricultural-exemption program still requires an application, completion within one year and an inspection; buildings must be outside special flood-hazard areas, at least 20 feet from property lines and 23 feet from dwellings, with separate electrical and plumbing permits and no mechanical installations8.
  • Only 1.9% of Tehama County soils rate free of severe limitations for a conventional septic drain field, so obtain an Environmental Health site evaluation before assuming a standard system will work930.
