HPRB Approved Replacement Windows Washington DC: What Homeowners Need to Know

Why Historic Windows Are Treated Differently In Washington DC

In Washington DC, window replacement is rarely a simple swap, especially when a home sits in a historic district or has been identified as a contributing property. The Historic Preservation Review Board, or HPRB, is there to make sure exterior changes still fit the age, scale, and look of the house and the block.

The historic district window replacement rules Washington DC residents deal with are often less about banning work and more about controlling how the final result looks.
