When A Window Or Door Project Needs DPS Review

Homeowners often ask do window replacements need a permit in Montgomery County MD, and the short answer is that it depends on whether the job stays truly like-for-like.

Egress rules are not about style. They are about whether a person can get out quickly in an emergency and whether emergency responders can get in if needed.

A garage side door, patio door, or new rear exit may look simple on paper, but once framing and code compliance enter the picture, it stops being a basic finish project.

Timing matters here. Ordering custom windows or doors before the review is complete can leave you with a product that does not match the approved opening.
