Changing Window Opening Size Permit Requirements Bethesda
When A Window Opening Size Triggers A Permit
If the replacement unit goes back into the same rough opening, the project often sits in a different category than a remodel that changes the size of the opening itself.

Replacement Windows Versus Altered Openings
