Accessory dwelling units (ADUs) in Closter, New Jersey

New Jersey has no single statewide ADU law. Each of the state's 564 municipalities, Closter (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 Closter, how big, and how tall depends on the town's ordinance and your specific lot. We have not sourced Closter's zoning ordinance yet, so we cannot tell you what Closter permits on your lot. That is a gap in our record, not a finding about Closter. What we can do today is measure the lot itself: its dimensions, what already sits on it, and its flood exposure.

ADU FAQ

Can I build an ADU in Closter, NJ?

Closter sets its own ADU rules under New Jersey's home-rule system. Many NJ towns allow ADUs by right in residential zones; some require a variance. We have not sourced Closter's ordinance yet, so we cannot confirm what it permits. Run your Closter address and we will show you what we do hold for that lot, and say plainly what we do not.

How much does an ADU cost in Closter?

A detached ADU in Closter typically runs $150,000 to $300,000+ all-in depending on size, site, and finishes. Because the build is financed, you can add rental income to your Closter property without paying the build cost up front, and the rent helps carry the loan.

Do I need to live on-site to build an ADU in Closter?

Some NJ towns require owner-occupancy; others (like Jersey City) don't. We check Closter's specific ordinance for you when you run your address.
