Do You Need a Permit to Replace Windows in Montgomery County MD?

When homeowners in Montgomery County MD start pricing a window project, the permit issue usually surfaces fast. Some jobs are simple like-for-like swaps, while others need county review, especially if you are changing the opening, altering the frame, or working on a home with historic restrictions.
