A like-for-like replacement in an existing opening may be treated differently from a project that enlarges a window, changes a window to a door, or adds a new opening altogether.

This is the part that surprises people most. A project that looks like a cosmetic upgrade can still need approval if the framing, lintel, masonry, or egress details change.

The Steps That Save Time And Rework

- Will the replacement stay in the same opening, or will the framing change?

- Is the house old enough that lead paint safe window replacement pre-1978 Baltimore homes or EPA RRP lead-safe window installation Baltimore rowhouses rules may apply?
