What Triggers A Window Permit In Baltimore City

A permit is more likely to be required when the work goes beyond basic swap-out installation and starts affecting framing, headers, lintels, or exterior features.

• altering the opening size or profile
• modifying structural framing or masonry around the opening
• adding a new window where none existed before
• changing a regulated exterior elevation
• handling commercial or mixed-use property, which is often reviewed more closely
