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