Montgomery County DPS Window Replacement Permit: A Quick Overview

Which Window Replacement Projects Trigger A Permit

Most of the review comes down to three things, the opening size, the energy performance of the new window, and whether the home is in an area with special preservation rules.

If the work is in a basement, the question can shift from simple replacement to egress compliance.

• Handling a bedroom or basement opening where egress code applies
• Working on a historic facade or a home under preservation review
• Changing the window type in a way that alters framing or the exterior look, such as moving from a double-hung window to a bay window, picture window, or specialty window
• Adding framing repairs, trim rebuilds, or significant water-damage repair around the opening
