Understanding the Montgomery County DPS Window Replacement Permit

The Triggers For A Window Replacement Permit

In the field, I usually start with a short checklist: - Is the opening staying the same size? - Does the window serve an area where escape and rescue dimensions matter? - Does the exterior need historic approval before the permit can move ahead? - Are you replacing the unit only, or modifying the wall framing too?
