Orange County Window Requirements Lookup
Search by city for jurisdiction rules, or by property address to also check the official fire hazard severity zone. Covers all 34 incorporated Orange County cities plus unincorporated Orange County.
“Permit exempt” does not mean “code exempt”
In Irvine, Huntington Beach and San Clemente a qualifying like-for-like replacement may not require a building permit, but the work still has to comply with the law:
- • California Energy Code fenestration requirements still apply.
- • Required safety glazing still applies in hazardous locations.
- • Emergency-escape (egress) openings cannot be improperly reduced.
- • HOA and condominium architectural rules may still apply.
- • Historic, coastal, floodplain, environmentally sensitive and fire-overlay areas may require separate approvals.

Planning a Window Replacement Project?
Share your project details and we will introduce you to independently licensed window replacement contractors serving your Orange County city. There is no cost and no obligation.
We are not a contractor. We do not perform construction services, quote projects, or hold contractor licenses.
Permit determinations are drawn from each jurisdiction's own official building-division guidance and are dated with the last verification. Fire hazard severity zones come from the official CAL FIRE / Office of the State Fire Marshal maps, and a mapped zone does not by itself establish a glazing requirement for a replacement window.
