Do I need a permit for window or exterior door replacement in Forest Hills?
It depends. Whether window or exterior door replacement needs a permit in Forest Hills comes down to the details of your project.
Forest Hills says a permit applies to any work that physically changes structures already on the property, so enlarging, relocating, or adding a window or door opening or altering a header needs a City permit; a simple like-for-like swap in the same opening is often minor, but confirm with the City first. Permits are applied for online through the City Permit Database and reviewed against the City Zoning Ordinance bulk standards; the work must meet the adopted 2018 International Residential Code, including egress and safety glazing. This is general guidance and not a City determination, so contact the City of Forest Hills Building and Zoning office to confirm whether your specific window or door work needs a permit. Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule. 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 programme applies, those come from the 2018 International Residential Code it enforces; where a local government runs its own programme, they come from the edition that government adopted.
