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

Permit may be required

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

Under the Pennsylvania UCC a straight like-for-like replacement in the same opening is often treated as an ordinary repair with no permit, but enlarging or relocating an opening, or changing an emergency-escape (egress) window, is an alteration that requires a permit. The UCC is enforced locally, so a few municipalities treat replacement more strictly than others. Confirm scope with the code official or third-party agency for your municipality. Pittsburgh's Work Not Requiring a Permit list exempts ordinary repairs, but cutting away a wall or enlarging an opening is not an ordinary repair and needs a Building and Development Application through OneStopPGH; confirm your like-for-like swap with PLI before assuming it is exempt. The Historic Review Commission specifically reviews the type and design of windows and doors, so a designated landmark or historic-district property needs a Certificate of Appropriateness even for a replacement that would otherwise be exempt.
