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 Hoboken 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 Hoboken'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.

No. P-58], and it is listed only as a CONDITIONAL use in the R-1(CS) and CBD(H)(CS) Court Street subdistricts, with one off-street space in the garage below (R-1(CS)) and a 30 ft total height cap for the accessory building.
See exactly what your lot allowsNew Jersey has no single statewide ADU law. Each of the state's 564 municipalities, Hoboken (Hudson County, NJ) included, sets its own zoning for accessory dwelling units (granny flats, in-law suites, backyard homes). Whether you can build one in Hoboken, how big, and how tall depends on the town's ordinance and your specific lot. We've mapped Hoboken's residential zoning: buildings are capped around 40 ft / 3 stories. Your ADU follows the town's accessory-structure standards on top of that.
