The Department of Buildings (DOB) protects the health, safety, economic interests and quality of life of residents, businesses and visitors in the District of Columbia.
To achieve our mission, DOB regulates construction activity through the process resulting in the issuance of construction permits. After receipt of applications and thorough reviews of construction documents to ensure compliance with building codes and zoning regulations, construction activity and buildings are inspected and rendered safe for occupation.
Throughout this process, DOB is here to help you identify the best course to get your project under way and get your building sooner.
