Unincorporated Fresno County, California requires a building permit for most construction, remodeling and manufactured-home placement, issued by the county's Development Services division1. The county zones unincorporated land under its Zoning Ordinance2, and Environmental Health issues septic permits3. Owner-builders may do qualifying work with the county's owner-builder form, permits and inspections4. Cities such as Fresno run their own building permits and zoning5.

Do you need a building permit in unincorporated Fresno County?

Yes. Unincorporated Fresno County requires a building permit for the erection, construction, enlargement, alteration, repair, moving, improvement, demolition or conversion of a building or structure unless a specific exemption applies110. Examples include a detached tool shed up to 120 square feet, a fence up to 7 feet, and a retaining wall up to 4 feet unless it supports a surcharge or impounds specified liquids10. A detached, one-story Group U accessory structure may qualify at no more than 240 square feet of floor or column area, 380 square feet of roof area, and 10 feet of wall or post height; claiming that exemption still requires a Citizens Portal filing, site plan, elevation, operational statement, contractor or owner-builder information, waste plan, and applicable fees11. This is not a blanket agricultural-building exemption12. Fresno County's Title 15 adopts the California Building Code by reference, and the 2025 California Building Standards Code applies to permit applications dated January 1, 2026 or later1314. Standard-plan permits issued between January 1, 2023 and December 31, 2025 stay valid for 12 months from issuance; if construction has not started by then, the permit falls under the 2025 code13.

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

Fresno County Development Services — Building & Safety handles building permits, plan checks, and inspections for unincorporated Fresno County at 2220 Tulare Street in Fresno15. For permit and plan-check questions call (559) 600-4570; Building Inspection is (559) 600-4560, and the 24-hour inspection-request line is (559) 600-413115. Inspection requests must be placed by 2:30 p.m. on the business day before the requested inspection day16. For a qualifying residential project, Fresno County must determine completeness within 15 days, then complete project review within 30 days for 25 units or fewer or 60 days for 26 units or more17. County building-permit fees increased by 3% on July 1, 2026; budget from the current Master Schedule of Fees18.

Does Fresno County have zoning?

Yes. Fresno County's Zoning Ordinance regulates land use in the unincorporated area under the General Plan and applicable specific plans219. The county publishes the complete ordinance plus separate materials for zones, allowable uses, and zone-specific standards20. Inside city limits, Fresno21, Coalinga22, Parlier23, Mendota24 and Huron25 set their own zoning, and the same five issue their own building permits526272829. The county's rules here cover unincorporated land, so confirm the parcel's jurisdiction first. Septic and well permits stay with county Environmental Health30. Lot size, setbacks, and height all depend on the district313233. For example, the main-structure limit without discretionary approval is 25 feet in R-1, 35 feet in R-2, 20 feet in R-2-A, 40 feet in R-3, and 20 feet in R-3-A343536. We could not confirm a general minimum floor area for an ordinary house; the SRO size rule is specialized and does not answer that question8. Fresno County allows ADUs only on eligible parcels and prohibits using an RV or trailer as an ADU37. A new ADU on a septic property needs its own separate septic system, and an ADU on a sewered property may share the main house's waste piping if it is large enough or tie in separately38. The county page also states that ADUs are currently not allowed within low water areas38.

How do septic and well permits work in Fresno County?

Fresno County Environmental Health regulates septic design, installation, operation, and wastewater dispersal in unincorporated Fresno County under the county's Local Agency Management Program339. During a site evaluation, county staff inspect with the qualified professional, log soil test holes, and make an initial suitability determination40. Before inspection, a septic tank must be filled with water to the flow line, its seams and joints must remain exposed except at the bottom, and the system must pass a flow test40. Only 5.8% of Fresno County soils have no severe limits for a conventional drain field, so establish feasibility early41. Special sewage-dispersal systems for minor, limited, or temporary uses need prior county approval; Fresno County's rule does not establish unrestricted approval for a composting toilet or another specific off-grid system42. Environmental Health also issues well-construction permits in unincorporated areas, although operating a completed private well needs no separate permit9. Reach the office at 1221 Fulton Street, 3rd Floor, Fresno, CA 93775, phone (559) 600-335730.

Can you live in an RV or tiny home in Fresno County?

A tiny home can be legal in unincorporated Fresno County only on an approved site and in a form that complies with the applicable rules6. If it is the first dwelling, the property must comply with the California Subdivision Map Act and Fresno County zoning, grading, and building rules43. A chassis-based tiny home must have axles, contain no more than 400 square feet excluding loft space, and qualify as an RV, commercial coach, or park trailer; a non-chassis unit must be permanently affixed and meet applicable building or factory-built-housing standards6. Ask Fresno County Zoning whether the parcel's district allows the proposed installation4344. Fresno County defines RV-park spaces as temporary occupancy in a district allowing recreational uses; those spaces may also serve tent campers7. The county's RV-park ordinance does not establish a general authorization for long-term RV occupancy on private land outside an RV park7, so do not plan on living in an RV on a bare parcel. We could not confirm whether any exception exists for temporary camping on private land, so ask Fresno County Zoning before buying or building around either use44.

Building a home in Fresno County: the steps, in order

  1. Confirm the parcel's jurisdiction, zoning district, allowable use, lot size, setbacks, and height standard with Fresno County Zoning4420.
  2. Check floodplain status; work in a Special Flood Hazard Area requires a building and/or grading permit and licensed professionals4546.
  3. If public sewer is unavailable, complete Environmental Health's septic site evaluation before fixing the house location4030.
  4. If the project needs a well, have a licensed well driller obtain the well-construction permit from Environmental Health930.
  5. Choose a licensed contractor or owner-builder route; an owner-builder must complete the county form, verify the owner's signature, and accept legal and financial responsibility4.
  6. Submit the building-permit application and use the current fee schedule1718.
  7. Schedule required inspections; requests must be placed by 2:30 p.m. on the prior business day1615.
  8. Apply for the certificate of occupancy with the building-permit application and do not occupy the building before issuance47.

What to check before you buy land in Fresno County

Start with septic feasibility: only 5.8% of Fresno County soils have no severe limits for a conventional drain field, so a site evaluation can materially affect the build plan and budget41. Terrain varies sharply: 38.6% of the county is at a 15% grade or less, 31.8% is wooded, and federal land covers 40.5%484950. Severe drought occurs in about 40.3% of years, and projections show roughly 34.1 days annually at or above 100°F by mid-century5152. If a purchase depends on splitting land, new parcels must meet the minimum parcel size in the zoning ordinance and the county's Division of Land rules53. A Tentative Tract Map generally applies to 5 or more lots, requires a Planning Commission hearing, and has at least a 90-day processing estimate plus a 15-day appeal period54. Farmland averages about $16,378 per acre, a typical home value is about $411,442, and the median property-tax bill is $2,704 per year at an effective rate near 0.7%55565758. The nearest city of 100,000 or more is about 6 miles from the county's center59.

Watch-outs

  • Fresno County recreational vehicle parks provide spaces for temporary occupancy, and the county ordinance does not authorize long-term RV living on private land outside a park; ask Fresno County zoning about temporary camping before relying on it744.
  • We could not confirm Fresno County's rules for short-term rentals or driveway access on unincorporated parcels; ask Fresno County zoning about both before buying or designing around either use44.
  • Fresno, Coalinga, Parlier, Mendota and Huron run their own building permits and zoning, and other incorporated cities set their own rules too; the county rules and offices in this guide apply only to unincorporated land2122232425.

Water rights & wells in Fresno County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from California’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellPermit required — restricted

California requires no STATE permit for a domestic well — wells are permitted by the county — but under SGMA a Groundwater Sustainability Agency can meter or restrict new wells in medium/high-priority and critically overdrafted basins, and Executive Order N-7-22 requires counties in those basins to get GSA verification that a new well is consistent with the Groundwater Sustainability Plan before permitting.

Limit: 2 acre-feet/year de minimis under SGMA (Water Code §10721(e)) — largely exempt from GSA metering/fees
