On behalf of the District Department of Transportation (DDOT), which regulates parking in the District, DC DMV issues permits for residential parking privileges to those who qualify. DC DMV also issues vehicle registration reciprocity privileges to those who are permanent residents in other jurisdictions, but who, by law, are allowed reciprocal residency privileges in the District. Reciprocity privileges are also issued to some temporary District residents.
Please note that reciprocity does not allow you to disregard DDOT's parking regulations and restrictions.
