Public Space Oversight

The System Inspection and Oversight Division (SIOD) is the investigative and enforcement arm of the District Department of Transportation and monitor all activities which may impact the public space. The SIOD conducts inspections of the work for which permits are issued to assure that permit holders adhere to permit conditions, requirements and are in compliance with DC laws.

The SIOD also investigates and initiates enforcement actions in cases of work performed in public space without a permit. To report a possible public space violation, please call 311.
