Do I need a permit for window or exterior door replacement in City of Niagara Falls?

Permit may be required

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

No New York exemption names window or door replacement; a local program may exempt it only as a repair that does not affect the structural system, means of egress, or fire protection (19 NYCRR 1203.3(a)(1)(viii)), and new or enlarged openings need a permit. Replacement windows must meet the U-factor and SHGC values in Table R402.1.3 of the 2025 Energy Conservation Construction Code of New York State (ECCCNYS R503.1.1.1); storm windows and glass-only replacement in an existing sash and frame are excepted (R503.1.1). A replacement window in a required emergency escape opening may be the manufacturer's largest standard size that fits the existing frame or rough opening, if it is not part of a change of occupancy (RCNYS R319.5).
