Seal Beach • Permit FAQ & no certified coastal program
Window Replacement in Seal Beach, CA
Seal Beach's own FAQ names window replacement as a minor project that needs a permit, and the city doesn't have a certified Local Coastal Program, which changes how coastal rules apply. Here's what the city says, how the coastal and flood questions work, and what we couldn't confirm, with sources.

Seal Beach specifics
Three things to know before a Seal Beach window project.
Window replacement is a named permit example
The city's FAQ says any building or structure erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted or demolished requires a Building Permit, and lists window replacement as an example of a minor project that needs one. The exemptions it names are finish work and fences of 6 feet or less, and it says electrical, plumbing and mechanical work is never exempted.
No certified Local Coastal Program
According to a Coastal Commission staff report we saw as a search extract, Seal Beach does not have a certified Local Coastal Program, so development is reviewed against the Coastal Act's Chapter 3 policies and Coastal Commission rules apply directly. The Coastal Act generally exempts improvements to existing single-family homes, except on a beach, in a wetland, seaward of the mean high tide line, within 50 feet of a bluff edge or in sensitive or scenic areas.
Flood zone questions
The city's FAQ says the Building Division can determine zoning and flood zone designations when you prepare plans. A window-only job rarely triggers substantial-improvement rules, but a larger remodel could, so ask if windows are part of one.

Permits & coastal review
What applies to a Seal Beach window project
We found no Seal Beach source saying window replacement specifically needs or is exempt from a coastal permit.
Permits
Plan on a building permit, and ask the Building Division about your zoning and flood zone designations as you prepare plans. We couldn't read the municipal code section, so we can't say what it says about windows.
- Ask your installer who pulls the permit
- Ask the Building Division about zoning and flood designations
- Ask whether windows are part of a larger remodel that could change the review
Coastal and fire questions
Like-for-like window replacement on an existing home is generally the kind of improvement the Coastal Act exempts, but homeowners near the beach should confirm with the city. We couldn't read Seal Beach's designation on the 2025 fire hazard maps, so check your address; Seal Beach is one of OCFA's contract cities.
- Ask whether your address is near a bluff or the beach
- Check your address on the state fire hazard severity zone viewer
