Do I Need a Permit to Replace Windows in Bethesda MD? Common Scenarios

For many homeowners, the question comes up only after the old sash is already measured and the replacement quote is in hand: do I need a permit to replace windows in Bethesda MD?

When A Window Replacement Usually Does Not Need A Permit

This is where many homeowners get confused. A window can look "new" from the street and still be a no-permit job if the installation does not change the opening or affect the structure. The material of the window, whether it is vinyl, fiberglass, or wood, is usually less important than whether the actual opening is being altered.

Practical Steps Before You Order Windows
