Where Permits And Historic Review Usually Come Into Play

The short answer to do I need a permit to replace windows in Baltimore City is that it depends on whether the work is simple replacement, structural change, or historic-district review.

In some cases, repair and restoration make more sense than full replacement, especially when the existing frame is sound and the original detail still survives.
