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