CHAP Historic District Window Replacement Rules in Baltimore

What Makes CHAP Window Replacement Different In Baltimore

In a CHAP area, windows are one of the first things reviewers notice because they change the look of the street from the sidewalk.

In many Baltimore rowhomes, the original wood windows are part of the architectural rhythm of the block.

What CHAP Usually Looks For Before Approving A Replacement

Whether repair is still practical for the existing frame and sash Whether the new unit matches the original divided-light pattern or exterior appearance Whether the material and sightlines look correct from the exterior Whether the opening, trim, and proportion stay intact Whether the work preserves the historic character of the facade
