Accessory dwelling units (ADUs) in Mount Laurel, New Jersey

Whether you can build one in Mount Laurel, how big, and how tall depends on the town's ordinance and your specific lot. We have not sourced Mount Laurel's zoning ordinance yet, so we cannot tell you what Mount Laurel permits on your lot. That is a gap in our record, not a finding about Mount Laurel. What we can do today is measure the lot itself: its dimensions, what already sits on it, and its flood exposure.
