An accessory dwelling unit (ADU), a granny flat, in-law suite, or backyard home, can add rental income or family space. Whether Howell 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 Howell'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, Howell (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 Howell, how big, and how tall depends on the town's ordinance and your specific lot. We've mapped Howell's residential zoning: buildings are capped around 30 ft / 2.5 stories, with a minimum lot area near 5,000 sf. Your ADU follows the town's accessory-structure standards on top of that.

A detached ADU in Howell 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 Howell 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 Howell's specific ordinance for you when you run your address.
