Illegal Construction

If your home is within the Capitol Hill Historic District, be sure to check the website of the Capitol Hill Restoration Society (CHRS) for important information and guidelines for maintaining your home.

Any construction done without required building permits is illegal construction.

To report illegal construction, call DC’s Department of Consumer and Regulatory Affairs Illegal Construction Unit, at (202) 442-7867 or call 3-1-1 during non-business hours and you will be routed to an on-duty inspector.

Be prepared to give the address and describe the illegal construction. DCRA will schedule an inspection to investigate.

There is a $2000 fine per infraction for:

  • Work without a permit
  • Work outside the scope of a permit
  • Work before 7am or after 7pm Monday through Saturday or any time on Sunday, and on holidays.

If you break these laws again, you may be fined up to $4,000 per infraction.

If you get a Stop Work Order for illegal construction, you will also have to pay a fine of 50 percent of the cost of the permit you should have obtained.
