Accessory dwelling unit rules in Ocean County are set by each municipality's zoning ordinance. New Jersey does not have a statewide ADU mandate like California. Most Ocean County municipalities do not specifically address ADUs in their zoning codes, though some allow accessory apartments as a conditional use in certain zones. The NJ MLUL gives municipalities full authority to regulate or prohibit ADUs through their master plans and zoning ordinances. Pinelands Commission density and impervious coverage limits may restrict ADU development in Pinelands-area townships.
