Understanding Window Permits for Baltimore City and County

For Baltimore property owners, the first hurdle is often not the window itself, but figuring out whether the job needs city, county, or historic approval.

• Is the property in a historic district or otherwise subject to review?

If the answer to any of those is yes, the safer move is to confirm the permit path before ordering materials.
