What Is a HAWP Historic Area Work Permit for Window Replacement in Bethesda?
Why Window Replacement In Bethesda Can Require Historic Approval
A window replacement in Bethesda is not always just a construction decision, especially when the house is tied to historic district rules or a preservation overlay.
A HAWP is the preservation approval that may be required before changing exterior features on a protected property.
