Do Window Replacements Need a Permit in Montgomery County, MD?

When Window Work Is Typically Exempt From A Permit

For many standard replacements, the answer is no, not if the new window is a true like-for-like swap and the opening stays the same size.

That applies to reframing for a larger window, converting a window into a door, altering structural headers, or changing the window’s location on the wall.

What To Check Before You Buy New Windows
