ADU rules in Holiday City-Berkeley, NJ — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
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.
New Jersey does not have a statewide law requiring municipalities to allow ADUs. Whether Ocean County permits accessory dwelling units depends on the local zoning ordinance per the NJ Municipal Land Use Law (N.J.S.A. 40:55D-1 et seq.). NJ has considered ADU legislation but has not enacted it as of 2025. Some municipalities allow ADUs by conditional use or variance. NJ’s smaller lot sizes and density create additional challenges for ADU development. Where allowed, typical conditions include owner-occupancy, size limits, and dedicated parking.
Unpermitted ADU: code enforcement. Zoning violation: $100 to $2,000/day. May require removal of unpermitted unit.
