Fountain Valley specifics
Four things to know before a Fountain Valley window project.
An expedited window and door permit
The city's Permit Center page lists Window and Door Replacement as an expedited permit type, with a Window Replacement Worksheet and a floor plan submitted online. The Building Permits page lists exempt work such as sheds, fences, retaining walls, interior finishes and awnings; window replacement isn't on it. A separate Work Exempt from Permits handout exists that we didn't open.
The worksheet's egress exemption
The city's worksheet says that for single-family and duplex homes, a replacement that is the largest standard size window that fits the existing frame or rough opening is exempt from the escape-size requirement. Otherwise bedroom windows need a 5.7 square foot net clear opening (5.0 at grade), 24 inches height, 20 inches width and a sill no higher than 44 inches. The worksheet's file is dated 2019, so ask the city whether it's current.
Counter hours, closed Fridays
The Building Division is at 10200 Slater Ave., (714) 593-4429, open Monday to Thursday 7 a.m. to 6 p.m. and closed Fridays, per its Building Permits page.
City water, no window rebate listed
The city's water efficiency rebate page lists items like toilets, washers, irrigation and turf, and no windows. We found no Edison or SoCalGas window rebate page, so don't assume one.

Permits & energy rules
What to confirm before ordering
We found no confirmed like-for-like permit exemption, so we don't claim one.
What the worksheet covers
It says all new or replaced glazing must meet the current California Energy Code for U-factor and SHGC, and lists safety glazing locations and window opening control devices for some low-sill upper-floor windows. It also lists light and ventilation at 8% and 4% of floor area.
- Ask your installer to fill in the worksheet
- Keep the energy label for each window
- The inspector makes the final determination
Fire zones and climate zone
We found no city page saying whether Fountain Valley adopted the 2025 fire hazard maps or has any mapped zone, and we couldn't confirm its CEC climate zone from a primary source. Use the state viewer and the CEC lookup.
- Check the State Fire Marshal's fire hazard severity zone viewer
- Look up your climate zone with the CEC tool
