Your property
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 Cape May 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 Cape May'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, Cape May (Cape May County, NJ) included, sets its own zoning for accessory dwelling units (granny flats, in-law suites, backyard homes). Whether you can build one in Cape May, how big, and how tall depends on the town's ordinance and your specific lot. We've mapped Cape May's residential zoning: buildings are capped around 35 ft, with a minimum lot area near 43,560 sf. Your ADU follows the town's accessory-structure standards on top of that.

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