What Is a HAWP Historic Area Work Permit for Window Replacement in Bethesda?

When A Window Project Triggers Historic Review

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.

• Whether the muntin or divided-light pattern fits the age and style of the home

What Homeowners Should Gather Before Submitting

• Photos of the existing windows from inside and outside
• Measurements for each opening
• Product literature for the proposed replacement window
