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