DOB does not approve After-Hours permits for work in the public right of way. Please contact the District Department of Transportation for requests for after-hour construction related to public space permits. After-Hours permits are not required for the following construction: interior painting, wallpapering, carpet installation, cleaning, or similar activities performed on the interior of a structure. Please note that these construction activities are still subject to District noise regulations in DCMR Chapter 20.
