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 Belmar 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.
We've mapped Belmar's residential zoning. An ADU on your lot follows the town's accessory-structure standards: check your specific address for the exact size, height, and setback it allows.

New Jersey has no single statewide ADU law. Each of the state's 564 municipalities, Belmar (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 Belmar, how big, and how tall depends on the town's ordinance and your specific lot. We've mapped Belmar's residential zoning: buildings are capped around 35 ft / 2.5 stories. Your ADU follows the town's accessory-structure standards on top of that.

A detached ADU in Belmar 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 Belmar property without paying the build cost up front, and the rent helps carry the loan.
Some NJ towns require owner-occupancy; others (like Jersey City) don't. We check Belmar's specific ordinance for you when you run your address.
