How DCRA And Historic Review Usually Work Together

In DC, a permit is not always the same thing as preservation approval. The building department looks at code compliance, while historic review can control what materials, profiles, muntins, and visibility the replacement can have.

Clear documentation matters because small differences, like sash proportion or grille placement, can change whether the replacement is seen as compatible or out of place.
