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

Unincorporated Tulare County requires a building permit before constructing a new residence; additions, remodeling and most repairs or alterations also require building permits¹. The permit holder must request building inspections, keep the permit and approved plans on site, meet other departments’ conditions, and obtain final Building/Zoning Inspector approval before occupancy^9,10. Applications must comply with the 2025 California Building Codes¹⁰. A homeowner obtaining a Tulare County building permit as an owner-builder becomes the contractor of record; the licensing exemption leaves building permits and inspections in place¹. An Agricultural Exempt Structure without electricity, plumbing or gas still needs a building permit, though simplified review and fewer inspections may apply; residential use requires separate approval¹¹. A Certificate of Occupancy is generally required for new commercial buildings, changes in occupancy and certain remodeled spaces in unincorporated Tulare County; ask the Permit Center whether your project qualifies¹.

The Tulare County RMA Permit Center, at Government Plaza on South Mooney Boulevard in Visalia, is the county's one-stop office for building permits, open Monday through Friday from 9:00 a.m. to 4:30 p.m².. A full permit, covering demolition, room additions, alterations and new construction, requires a site plan, construction plans, engineering calculations and energy calculations, with a minimum submittal fee of $154 for most submittals; paying by credit card adds a 3.5% fee, and paying cash requires an appointment¹². Fees vary beyond that minimum depending on permit type, project scope and how many other departments have to review the project, so ask the Permit Center for a project-specific estimate before you budget¹. If your project touches a Special Flood Hazard Area, you'll need a building permit under the county's flood damage prevention ordinance before construction starts there too, administered jointly by the Planning and Public Works Directors as Floodplain Administrators¹³. Inside Porterville and Woodlake, city offices handle building permits; Environmental Health’s septic jurisdiction still reaches city properties^4,14,15.

Every unincorporated Tulare County parcel has a zoning designation governing uses, lot size and setbacks; the county publishes district rules and an adopted zoning map^3,16. County zoning applies outside incorporated cities, which administer their own zoning processes¹⁷. R-A and R-1 main buildings generally need at least 6,000 square feet of lot area per family, subject to stated exceptions^18,19. R-A and R-1 front and rear yards generally require 25% of lot depth but need not exceed 25 feet; interior side yards require 10% of lot width, at least 3 feet, but need not exceed 5 feet, with frontage and corner-lot exceptions^18,19. Newly created AE-10 and AE-20 parcels generally require at least 10 and 20 acres respectively, with exceptions; these are parcel-creation standards, not dwelling floor-area minimums^20,21. Both agricultural districts require 25-foot front/rear and 10-foot side yards, with greater road setbacks where applicable^20,21. Visalia, Porterville, Dinuba, Farmersville, Exeter and Woodlake administer their own zoning; Environmental Health still regulates city septic systems^{4,22,23,24,25,26,27}.

Most construction, installation and repair work on an on-site wastewater treatment system (OWTS, commonly called septic) requires a permit in Tulare County; the county septic FAQ directs permit-requirement questions to the RMA⁵. Environmental Health and the RMA share regulation of OWTS design, installation, operation and liquid-waste dispersal, with Environmental Health regulating septic systems inside incorporated cities too⁴. Only 6.4% of Tulare County soils are rated “not limited” for a conventional drain field; that does not make septic impossible elsewhere, but supports arranging a site evaluation and allowing for an engineered design⁶. We could not confirm a universal septic inspection schedule or all exceptions; ask Environmental Health which inspections your project needs²⁸. Off-grid sanitation is not a blanket exemption: laundry, washing and bathing wastewater generally must enter the OWTS, while Plumbing Code provisions allow graywater use under conditions; ask the RMA Building Department about your proposal⁵.

Living in an RV or travel trailer on private property in unincorporated Tulare County is prohibited outside approved locations such as campgrounds or RV parks; contact the Permit Center before placing or occupying one¹. A tiny home on wheels is typically treated as an RV and is generally not approved for permanent residence under a standard residential building permit⁸. A site-built tiny home can qualify if it meets the California Building Code, a modular tiny home can qualify on a permanent foundation, and a manufactured tiny home can qualify with HUD certification, an approved permanent foundation, and zoning and building compliance¹. A manufactured home can serve as a primary residence in unincorporated Tulare County when installation meets zoning, building and foundation requirements; replacing an existing manufactured or mobile home also requires a building permit¹. In residential zoning districts the home must be 10 years old or newer, while in agricultural districts an older home may qualify after a pre-installation inspection and an Investigation Permit⁸. An ADU requires an existing or proposed primary home, adequate water and wastewater service, compliant setbacks, an allowed district, and applicable fire and access approvals; an RV cannot qualify as an ADU^1,29.

1. Confirm the parcel's zoning designation and permitted uses with the RMA before you design or buy³.
2. Apply for a full building permit at the RMA Permit Center with a site plan, construction plans, engineering calculations and energy calculations; the minimum submittal fee is $154 for most projects^2,12.
3. If you will act as owner-builder, review California's contractor-licensing exemption and its sale and occupancy limits; the exemption does not remove permit, inspection or zoning requirements⁷.
4. If the parcel lacks sewer service, coordinate the septic design and permit with Environmental Health and the RMA, and arrange a site evaluation early because only 6.4% of soils rate “not limited” for conventional drain fields, without assuming other soils cannot support septic^4,6.
5. Get an Environmental Health permit before constructing, destroying or inactivating a well anywhere in Tulare County, and use a contractor with a valid C-57 license³⁰.
6. Obtain an encroachment permit before work in a county road right-of-way; work in a state highway right-of-way requires a Caltrans encroachment permit^31,32.
7. Request each required building inspection, and do not occupy the building until the Building/Zoning Inspector gives final approval⁹.

Before buying unincorporated Tulare County land, confirm the parcel’s zoning with the RMA: minimum lot size, setbacks and allowed uses vary by district³. Only 6.4% of county soils rate “not limited” for conventional drain fields; that is a reason to evaluate the site, not proof that other parcels cannot support septic⁶. Environmental Health requires a permit for well construction, destruction or inactivation anywhere in Tulare County, and all well work requires a licensed C-57 contractor³⁰. County-owned water and sewer service is available only in some unincorporated areas through designated County Service Areas³³. About 50.9% of county land is federal, and 32.7% has slopes of 15% or less⁶. Annual precipitation averages 21.1 inches, with severe drought in 43.1% of years⁶. Farmland averages $15,617 per acre, typical home value is $365,579, and the effective property tax rate is about 0.7%, with a median annual bill of $2,213⁶.
