Short Answer
Often no permitIn San Diego, replacing windows in their existing openings needs no building permit in a detached single-family home, duplex or townhouse, as long as the rough openings and exterior weather-resistant flashing are not changed and the windows do not have to be fire-resistive or meet Very High Fire Hazard Severity Zone rules. Commercial properties and multifamily buildings need a permit.

Who Can Apply and Do the Work
Where a permit is needed, a same-size, same-type replacement with no change to the opening qualifies for a No-Plan Building Permit, issued without plan review (Information Bulletin 203). Only legally permitted buildings that passed final inspection can use one, and the inspector can require plans if the work turns out to be more extensive.
What You Need Before the Permit Is Issued
- Check whether the home is a designated historical resource or in a designated historic district: the exemption does not apply there, and Historical Review may be needed even for a No-Plan permit.
- Check whether the lot is in a Very High Fire Hazard Severity Zone.
- Confirm the rough opening and flashing stay unchanged; otherwise apply for a Building Permit.
What Else to Know in San Diego
Exempt work still has to meet the applicable codes and standards. New or enlarged openings are outside both the exemption and the No-Plan Building Permit.
