Historic DC Rowhouse Window Rules: What You Can and Cannot Do

For a historic rowhouse in Washington, DC, replacing or repairing windows is never only about energy savings or curb appeal. The historic district rules can shape what you can change, what you need to preserve, and how the city reviews the work.

What The Historic Review Process Usually Looks At

In most DC historic districts, the main question is not simply whether a window is new. Reviewers look at whether the proposed change preserves the overall appearance of the house, especially on the front facade and other highly visible elevations.

Permits, Approval, And What Can Go Wrong

What To Ask Before You Order New Windows
