Certificate of Occupancy

The purpose of a Certificate of Occupancy (“COO” or “C of O”) is to ensure that the use of a building, structure or land in the District of Columbia conforms to the Zoning Regulations (DCMR Title 11) provisions of the DC Construction Codes, and the Green Building Act.

In most cases, no person can use a building, structure or land in the District of Columbia for any purpose other than a single-family dwelling, until a valid Certificate of Occupancy has been issued.
