DOB alteration permit and exemption check for window or door work
NYC DOB says most construction requires approval and permits, while 1 RCNY 101-14 says permit exemptions for minor alterations or ordinary repairs do not remove obligations to comply with the construction codes, energy code, zoning, or other agency requirements, and do not remove DOB filing obligations for related structural, electrical, plumbing, or other work. Window or door projects should be confirmed with DOB when they change openings, exterior walls, egress, fire-rated conditions, landmark conditions, or energy-code scope.
