| What is a Vacant Property? | What Is a Blighted Property? |
|
“Vacant building” means a property that has not been occupied continuously. However, a residential building is only deemed vacant if it is determined that there is no intent for a resident to return and occupy the building. (D.C. Official Code § 42–3131.05 (5)) |
A blighted vacant building is one determined to be unsafe, insanitary or otherwise threatens the health, safety, or general welfare of the community. (D.C. Official Code § 42-3131.05 (1) (A)) |
Do You Have a Certificate of Occupancy?
- A Certificate of Occupancy (C of O) ensures that the use of a building, structure, or land in the District conforms to the Zoning Regulations (DCMR Title 11), the DC Construction Codes, and the Green Building Act.
- In most cases, a person cannot use a building, structure, or land in the District for anything other than a single-family dwelling until a valid C of O has been issued.
- There are six types of C of O applications; for more information, please visit our C of O process page.
- All C of O applications must be processed through our digital platform, Certifi.
