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

Window replacement in Baltimore City is not always as simple as pulling old units and setting in new ones. Whether a permit is needed depends on what is being changed, how the opening is being altered, and whether the home sits in a historic district or under a preservation review.

The Permit Question Starts With The Scope Of Work

In Baltimore City, the permit issue usually turns on scope. If the work stays close to a true replacement, without changing the rough opening or the framing around it, the process is often simpler.
