When Baltimore City Usually Requires A Permit For Window Replacement

The city looks harder at window projects that go beyond a simple replacement of an existing unit in the same opening.

That includes work such as enlarging or shrinking an opening, installing a new style that changes the look of the house, or altering trim and masonry around the window.

Historic Districts And CHAP Rules Change The Process

Historic neighborhoods in Baltimore deserve extra care, because CHAP historic district window replacement rules Baltimore can affect both the window selection and the approval path.
