CHAP Historic District Window Replacement Rules in Baltimore

Why Window Work In A CHAP District Is Different

For Baltimore homeowners, window replacement is rarely just about drafts or broken sash, because historic review can shape what you are allowed to change.

How CHAP Reviews Window Changes In Historic Baltimore Homes

When Replacement Makes Sense, And When Repair Is Smarter

Performance, Appearance, And Long-Term Trade-Offs
