Teaneck zoning & ADU rules

We have not sourced Teaneck's zoning ordinance or its ADU rules yet, so we cannot say what Teaneck permits on your lot. That is our gap, not Teaneck's. Run your address to see what we hold for it today.

Teaneck’s ADU rules, cited

The owner must live on the property.

Sources: Teaneck Code 33-56(d): 'Either the ADU or the PDU shall be the domicile of the person(s) who own(s) the property lot.' 33-55: 'PERSON: A natural person only and not a corporation, partnership, or other similar legally constructed entity.' 33-58(a): annual sworn affidavit 'that the owner resides in either the primary residence or the ADU.' 33-60(c): 'An ADU may not be sold independently of the primary residence.'; Teaneck Code 33-55 ADU definition (a): 'Constitutes an entirely self-contained portion of a principal, single-family dwelling, or is located in an accessory building on the same lot'; 33-56: 'in any residence or in any garage or accessory structure on the property lot'; 33-56(i) 'Detached ADU', 33-56(m) 'An ADU attached to the primary residence', 33-56(j) an ADU 'constructed above a permitted detached accessory structure'.; Teaneck Code 33-56(e): 'The total floor area of an attached ADU shall not exceed 40% of the floor area of the PDU, or to a maximum floor area of 800 square feet, whichever is greater'. Because it is 'whichever is greater', 800 sf is the minimum the cap ever allows, and a PDU over 2,000 sf allows 40% of its floor area; recorded as 800 only so a 'whichever is less' reader does not under-size large homes. Applies to attached ADUs only.

Accessory dwelling units (ADUs) in Teaneck, New Jersey

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