Several DC agencies are responsible for enforcing parking:

• DPW, as well as other agencies, enforce the public space regulations, including parking.
• DC DOT regulates the use of public space. This includes identifying where signs and meters are installed.
• DC DMV adjudicates the tickets written by DPW and determines what happens next.

Call 311 to request parking enforcement for violations such as expired meter, parking longer than allowed in a Residential Permit Parking neighborhood, morning and afternoon rush hour, expired tags, ROSA, blocking a driveway, bus stop, crosswalk, or fire hydrant.

Note: The Department of Motor Vehicles adjudication process is available to anyone who believes a ticket was issued erroneously. During this process motorists have the opportunity to submit supporting documentation that may lead to dismissal of a ROSA ticket, which generally is proof of residence outside of the District of Columbia. The adjudication process may be used to challenge tickets issued for any parking violation.
