Do I need a permit for window or exterior door replacement in Brentwood?

Permit may be required

It depends. Whether window or exterior door replacement needs a permit in Brentwood comes down to the details of your project.

Like-for-like replacement in the same opening may be treated as minor work in some jurisdictions, while enlarging or adding an opening triggers a full permit. Confirm with your local codes department before ordering. Egress, safety glazing and fall-protection requirements still apply to bedroom and hazardous-location windows even where no permit is required. Where the State Fire Marshal's residential program applies, those come from the 2018 International Residential Code it enforces; where a local government runs its own program, they come from the edition that government adopted.
