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

If you are planning window work in Baltimore City, the short answer is that a permit is often required when the project changes the opening, the frame, or the exterior appearance, and it may also be required when historic review applies.

• A structural member, masonry support, or lintel is being touched.
• The property is in a historic district or subject to design review.
• The project must follow lead-safe requirements because the home was built before 1978.
