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

For Baltimore City homeowners, the permit question is not always a simple yes or no. If the job affects the size of the opening, the structure, or the visible look of the house, you should expect permit review.

When A Baltimore Window Job Usually Triggers A Permit

These are the situations that most often lead to permit review:

• The size of the opening is changing, or the framing is being rebuilt.
• The replacement changes the exterior appearance of the home, especially on the front facade.
• 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.
