Checking what the rules allow in your town. This takes a few seconds.
An accessory dwelling unit (ADU), a granny flat, in-law suite, or backyard home, can add rental income or family space. Whether Long Hill Twp allows one, and how big, comes down to the town’s zoning and your specific lot. Here’s what we know, and how to check yours.

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