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 Shrewsbury Boro 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 Shrewsbury Boro's zoning ordinance or its ADU rules yet, so we cannot say what Shrewsbury Boro permits on your lot. That is our gap, not Shrewsbury Boro'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, Shrewsbury Boro (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 Shrewsbury Boro, how big, and how tall depends on the town's ordinance and your specific lot. We have not sourced Shrewsbury Boro's zoning ordinance yet, so we cannot tell you what Shrewsbury Boro permits on your lot. That is a gap in our record, not a finding about Shrewsbury Boro. What we can do today is measure the lot itself: its dimensions, what already sits on it, and its flood exposure.
