Top ZIP codes by recent activity
Housing law — District of Columbia
In the District of Columbia, accessory dwelling units follow the District's own zoning rules rather than any statewide mandate, since D.C. is a single jurisdiction.
Residential density in the District is governed by D.C.'s zoning code; there is no separate statewide upzoning law.
