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 Frenchtown 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 have not sourced Frenchtown's zoning ordinance or its ADU rules yet, so we cannot say what Frenchtown permits on your lot. That is our gap, not Frenchtown's. Run your address to see what we hold for it today.
From 596 real Frenchtown permits in the New Jersey DCA record. The largest group, international residential code, takes a median of 61 days from filing to issue (n=500). This is elapsed time, not review hours: it includes the waiting and the corrections.

New Jersey has no single statewide ADU law. Each of the state's 564 municipalities, Frenchtown (Hunterdon County, NJ) included, sets its own zoning for accessory dwelling units (granny flats, in-law suites, backyard homes). Whether you can build one in Frenchtown, how big, and how tall depends on the town's ordinance and your specific lot. We have not sourced Frenchtown's zoning ordinance yet, so we cannot tell you what Frenchtown permits on your lot. That is a gap in our record, not a finding about Frenchtown. What we can do today is measure the lot itself: its dimensions, what already sits on it, and its flood exposure.

We have not sourced Frenchtown's ordinance yet, so we cannot confirm what it permits. Run your Frenchtown address and we will show you what we do hold for that lot, and say plainly what we do not.
A detached ADU in Frenchtown 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 Frenchtown 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 Frenchtown's specific ordinance for you when you run your address.
Enter your address and we read Frenchtown’s zoning against your parcel and tell you if an ADU fits, how big, and what it could earn. Free.
