Many Valley cities issue permits for window change-outs, including like-for-like swaps, and new windows must meet the state energy code. Whether your exact job needs a permit depends on the city or county and the work. Here is what we know, and what to ask your building department.
Do I need a permit to replace windows in Fresno?
Ask the City of Fresno, because no city page we found says either way for a same-size swap. The city does say a permit is required to build, remodel or repair any house, and its list of work that needs no permit, such as finish work and small decks, does not include windows. New or larger openings change the structure and need a permit. Nearby, Visalia and Madera permit records show permits issued for like-for-like window replacements.
Who issues the permit, the city or the county?
The city issues it if you live inside city limits, and Fresno County issues it if you live in an unincorporated area. In Fresno, that is the Planning and Development Department, through the FAASTER online system. Clovis has its Building Division, Reedley, Tulare and Hanford have Building Divisions, and Visalia uses its Community Development Department. Fresno County's Department of Public Works and Planning runs an online Citizen Portal for county permits.
What do Valley cities say about window permits?
- Reedley: its building permit page lists "installation of new or structural alterations to windows or doors" as work that needs a permit.
- Visalia: weekly permit reports list like-for-like window change-outs in October 2026.
- Madera: permit records list window replacement permits, including a like-for-like patio door in March 2025.
- Clovis, Hanford, Sanger, Selma, Kerman, Fowler, Kingsburg and Fresno County: ask the building office.
What size do bedroom egress windows need to be?
A bedroom window used for emergency escape needs a net clear opening of at least 5.7 square feet, or 5.0 square feet on a ground floor. The opening must be at least 24 inches high and 20 inches wide, and the sill no more than 44 inches above the floor, under the California Residential Code. Using both minimum height and width does not reach the required area. A replacement can be allowed in an existing opening if it is the maker's largest standard size that fits and gives an equal or larger opening than the old window.
Where is tempered safety glass required?
The California Residential Code calls for tempered or other safety glass in places where people could fall into it. That includes:
- All glass in doors, including sliding patio doors.
- Glass within 24 inches of either side of a closed door, with the bottom edge under 60 inches from the floor.
- Panes over 9 square feet with the bottom edge under 18 inches, the top over 36 inches, and a walking surface within 36 inches.
- Glass at tubs, showers, spas and pools, with the bottom edge under 60 inches above the standing surface.
- Glass by stairs, ramps and landings, under the limits the code sets.
What about lead paint in homes built before 1978?
If your home was built before 1978, paid window work must follow the EPA's lead-safe rule. The EPA says paid renovation in pre-1978 homes must be done by certified firms, even a one-person business, with a certified renovator assigned to the job. Window replacement is not covered by the minor repair exception. Many ranch homes in Fresno and the older blocks of the valley towns were built before 1978. Ask any installer for its EPA firm certification.
Does my HOA have to approve new windows?
If you live in a homeowners association, check its rules before you order. Many HOAs in north Fresno and Clovis set the frame color, grid pattern or style that can face the street. Some need a written request and approval first. The city permit and the HOA approval are separate.
Can I change the size of a window opening?
Yes, but a bigger or new opening changes the wall's structure and needs a permit. A larger opening may need a new header, and the stucco or siding has to be cut and patched. Making a bedroom window bigger to meet egress size is a common reason. A smaller opening means filling in the wall.
Do new windows need an inspection?
If the job has a permit, an inspector usually checks it. California inspectors need to see the NFRC labels to confirm the windows meet the energy code, so leave the stickers on until the inspection is done. Some counties ask for the labels before installation. The inspector may also check egress and safety glass.
Who pulls the permit for a window job?
The contractor doing the work usually pulls the permit and files the energy compliance form. CSLB rules say anyone you hire for a job that needs a permit must be licensed, whatever the price. Ask who will pull the permit, get a copy, and do not let an installer talk you out of one.
