Do You Need a Permit to Replace Windows in Baltimore City?

For a lot of Baltimore homeowners, the short answer is "sometimes."

The permit question turns on the scope of work, the property type, and whether the building falls under extra review.

A straightforward swap in the same opening is often handled differently than a project that changes the frame size, alters the facade, or touches a historic exterior.

When Baltimore City Usually Requires A Permit For Window Replacement

That can include making the opening bigger or smaller, swapping to a different style that changes the home’s appearance, or modifying trim, masonry, or framing around the opening.
