What Happens If I Replace Windows Without a Permit in DC?

Why Window Permits Matter In DC

A window project in Washington DC can move from a simple home upgrade Washington DC Windows & Doors to a compliance issue quickly, especially in older housing stock.

That matters because windows affect more than the look of a facade.

If the property is in a historic district, the city often wants to know what materials you are using, how the sash profile will look, and whether the new unit matches the original opening.

What Can Happen If You Skip The Permit

You may be able to apply for approval after the fact, you may need to modify the work, or you may need to remove and replace the windows with compliant units.
