Accessory dwelling units (ADUs) in Barnegat, New Jersey
New Jersey has no single statewide ADU law. Each of the state's 564 municipalities, Barnegat (Ocean County, NJ) included, sets its own zoning for accessory dwelling units (granny flats, in-law suites, backyard homes). Whether you can build one in Barnegat, how big, and how tall depends on the town's ordinance and your specific lot. We have not sourced Barnegat's zoning ordinance yet, so we cannot tell you what Barnegat permits on your lot. That is a gap in our record, not a finding about Barnegat. What we can do today is measure the lot itself: its dimensions, what already sits on it, and its flood exposure.
