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