Temecula specifics
Four things to know before a Temecula window project.
Window-only jobs get permits
The city's published permit-issuance report lists window-only projects, including "like for like" retrofit change-outs described as Title 24 compliant, issued as Building (R) remodel permits. We found no city handout or code text stating an exemption, so confirm before you start.
2025 codes and the city's stated climate zone
The city's Codes & Standards page says it enforces the 2025 California codes through Title 15 of its municipal code, with local amendments in Chapter 15.04. Its stated design criteria include climate zone 10 and a 97 mph wind speed.
Old Town Historic Preservation District
A Certificate of Historical Appropriateness is required to alter, demolish or construct a building or structure in the Old Town Temecula Historic Preservation District. Minor alterations get administrative staff review, while others go to the Old Town Local Review Board, and the Planning Director sets the level. The handout doesn't mention windows specifically.
The 2025 fire hazard severity map
The city posted Cal Fire's March 24, 2025 update for its area, with a PDF map and an interactive address lookup showing Very High, High and Moderate zones. The page doesn't give an adoption date or building-code consequences.

Permits
Treat a window replacement as permitted work until the Building & Safety Division says otherwise, since the city issues permits for like-for-like retrofits. We couldn't confirm what the city's amended permit-exemption section says, so we don't claim an exemption.
- Permit Center: 951-694-6439
- Ask your installer who pulls the permit
- Ask what Title 24 documentation the city wants
Old Town and fire zones
If your home is in the Old Town district, speak with Planning before ordering, since the handout says to consult Planning first about the review level. For fire zones, we found no confirmed Chapter 7A or wildland-urban-interface window rule for Temecula, so check the city's map and ask.
