North Middletown FAQ
Does Monmouth County regulate ADUs?
No. Under New Jersey's Municipal Land Use Law (N.J.S.A. 40:55D), zoning belongs to each municipality. Monmouth County's 53 municipalities each set their own ADU rules; the county itself does not regulate accessory dwelling units.
Which Monmouth County town has the most permissive ADU rules?
Asbury Park — Ordinance 2024-7 (effective 4/16/2024) permits one ADU per legal 1- or 2-family property in a separate structure or the main structure, requires owner-occupancy of one unit, mandates yearly (not short-term) rentals, and offers a $25,000-$35,000 grant for deed-restricted affordable ADUs with a 10-year minimum deed restriction.
Can I build an ADU on a shore property in Monmouth County?
Often. Coastal properties typically face CAFRA (Coastal Area Facility Review Act) jurisdiction, FEMA V/AE flood zone elevation/floodproofing rules, and tidelands/wetlands buffers on top of the municipal ADU ordinance. Asbury Park ADUs in floodprone areas must meet FEMA elevation requirements. Always check NJDEP CAFRA mapping and FEMA flood maps.
