Replacement Windows Same Size No Permit Montgomery County: Is It True?

The Short Answer Depends On What Is Actually Changing

Same-size replacement can sometimes be treated as a straightforward project, yet that does not automatically remove permit, code, or historic review requirements.

If any one of those answers changes the job, the permit question can change with it.

What To Confirm Before The Crew Arrives
