Housing In Downtown

 

Housing in Downtown is an innovative initiative designed to catalyze new residential development in Downtown DC and add thousands of new residents downtown through a 20-year tax abatement for commercial-to-residential conversions.

DOB plays a key role in the HID initiative by approving building permit applications. Please review our HID Permitting Guidance flyer for more instructions.

For more information, please visit the Deputy Mayor for Planning and Economic Development's (DMPED) Housing in Downtown webpage.
