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.
