New Jersey has no statewide ADU law. Each of the state’s municipalities sets its own. Pick your town for its rules, or check your exact address to see what your lot allows.
Each of these towns allows an accessory dwelling unit in its own zoning ordinance, in the zones the ordinance names. Your lot still has to meet its rules, so check your address.
