Fresno County, California Building Permit Guide

Fresno County sits in the heart of the San Joaquin Valley with about 1 million residents across farmland, the valley floor and the Sierra foothills. The Department of Public Works and Planning is the building authority for the unincorporated areas outside its 15 cities, led by the City of Fresno.

This guide covers Public Works and Planning’s unincorporated-area role, Title 24 with county amendments, and the agricultural, septic and foothill-fire layers, and where city work goes instead.

This guide covers unincorporated Fresno County. The City of Fresno and the other cities each run their own permitting.

What requires a building permit in Fresno County?

Local amendments and thresholds differ from one jurisdiction to the next, so an exempt list from a neighbouring city is not reliable — a project waved through in one place needs a full permit set in the next. An exemption from a building permit is never an exemption from zoning, the statewide energy or green-building codes, or an electrical or plumbing permit. Confirm scope with Public Works and Planning before work starts.

The statewide layers that apply everywhere

Several parts of Title 24 apply on top of the base building code and routinely catch projects owners assume are exempt: the California Energy Code (Part 6); CALGreen (Part 11), California’s mandatory statewide green-building code; and the accessibility provisions in Chapters 11A and 11B. Seismic design is built into the code statewide, and in fire-prone areas the California Wildland-Urban Interface Code (Title 24, Part 7, in force since 1 January 2026) and Cal Fire defensible-space requirements (Public Resources Code 4291) add a further layer. In unincorporated Fresno County, the Department of Public Works and Planning administers Title 24 with county amendments, and on-site septic review and foothill fire-hazard requirements attach to many rural and mountain parcels.

California builds on one statewide code, Title 24, whose 2025 edition took effect on 1 January 2026; the editions in effect when the application is submitted apply, and cities and counties may adopt local amendments only with findings filed with the state (new residential amendments are largely frozen until June 2031).

Who handles permitting in Fresno County?

The Department of Public Works and Planning handles permitting and inspections for unincorporated Fresno County; the cities handle their own.

The Department of Public Works and Planning, through its Development Services and Capital Projects Division, is the authority for unincorporated Fresno County. Plans are filed online through the County of Fresno Citizens Portal or on paper at 2220 Tulare Street, Suite A, in Fresno (lobby counter Monday to Thursday 9am to 5pm, Friday 8:30am to 12:30pm), and plan check questions go to 559-600-4570. Rural parcels commonly add on-site septic review, and Sierra-foothill parcels add fire-hazard requirements to the building permit.

Confirm the jurisdiction from the parcel first; a project inside the City of Fresno or another city files with that city’s department under its own code and counter.

Permit types

Residential permits

Unincorporated residential work is permitted and inspected by the county under Title 24 and county amendments. Additions, decks, pools, solar and EV chargers need permits, rural parcels carry septic review, and foothill parcels carry fire-area requirements. A CSLB-licensed contractor pulls the trade permits.

Commercial permits

Commercial, agricultural and multi-family work in unincorporated areas goes through county plan check against the California Building Code, the Energy Code and CALGreen. It requires CSLB-licensed contractors and stamped drawings on most projects, with septic or fire review where the parcel calls for it.

Licenses, trade classifications and design professionals

Practically, three credential layers appear on California projects: a CSLB license in the correct classification for the contractor pulling the permit; the specialty C-classifications for the electrical, plumbing and mechanical trades; and, on commercial and larger residential work, drawings stamped by a California-licensed architect or engineer. Confirm what Public Works and Planning requires for the specific building before filing.

Contractors are licensed statewide by the Contractors State License Board (Classes A, B, B-2 and C) for work of $1,000 or more or any permitted work; a city may also require a business licence or tax registration. Contractor licensing in California

Fresno County permit costs and fees

Budget the county building permit and plan-check fees, separate trade permits, the state Building Standards and seismic surcharges, and septic or fire review where it applies. The county publishes a valuation-based schedule; confirm it for your filing date.

California layers two uniform state surcharges — the Building Standards Administration fee and the Strong Motion Instrumentation seismic fee — on top of the local charges (Health and Safety Code 18931.6; Public Resources Code 2705). The building and plan-check fees themselves are local and change, and California law limits them to the reasonable cost of providing the service, so a figure from a neighbouring city is not reliable — ask Public Works and Planning for the schedule in force on your filing date.

Trade permits and who may pull them

Each trade follows its part of Title 24 and is done by a contractor with the matching CSLB licence (C-10 electrical, C-36 plumbing, C-20 HVAC), a Class B contractor where allowed, or an owner-builder. Trade licences in California

How to apply for a Fresno County building permit

Review, corrections and what actually causes delay

In California, the first cause of delay is uncertainty over jurisdiction — filing with the county when a city should have it, or missing a local amendment on top of Title 24. After that come Title 24 energy and CALGreen documentation, a CSLB classification that does not match the scope, and, in fire or coastal areas, defensible-space or coastal-zone requirements that were not addressed up front. Build the plan-check time into the schedule and confirm the checklist with Public Works and Planning before filing.

A building permit carries a validity period and can expire if work does not start or stalls between inspections; confirm the expiry with Fresno County on phased or delayed work. Permit validity in California

Inspections in Fresno County

Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and Title 24 energy, CALGreen measures, fire systems on commercial work, and final, with a certificate of occupancy before use. On issuance the county assigns the field inspector and the construction stages that must be inspected.

California inspections are made against the code editions in effect when the permit application was submitted (Health and Safety Code 18938.5), so the approved plans and any energy and green-building documentation need to be on site for the inspector to check against. Confirm the notice Public Works and Planning needs and schedule around its inspection windows.

Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, product listings, Title 24 energy documentation and your correction responses available on site.

Fresno County permit search and official resources

Permit records in California sit with the local authority that issued them. Where the Fresno County Department of Public Works and Planning is the authority for unincorporated Fresno County, it holds the building permit, the inspection history and the certificate of occupancy. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was — and confirm the code edition that was in force.

These are the primary sources behind this guide. Codes, fee schedules and procedures change — confirm the position for your filing date.

Frequently asked questions

Who issues building permits in unincorporated Fresno County?

The Department of Public Works and Planning issues permits for unincorporated areas; the county’s cities, including the City of Fresno, run their own departments.

How do I know if my parcel is unincorporated?

Confirm with Public Works and Planning or the county mapping tools; farmland and foothill parcels outside the cities file with the county.

Do I need septic or groundwater review?

On rural parcels not served by sewer, on-site wastewater review commonly attaches to the building permit.

Does my foothill project need wildfire review?

Sierra-foothill parcels commonly carry fire-hazard requirements; confirm with Public Works and Planning before you file.

Do I need a local contractor registration?

Not a contractor licence: California licenses contractors statewide through the CSLB, and the licence must be active and carry the right classification. A city may still require a business licence or business tax registration (Government Code 37101), so ask the department.

How do I run a Fresno County permit search?

Public Works and Planning holds unincorporated permit and inspection records; city records sit with each city’s department.
