NJ A3710

Accessory dwelling units (ADUs) would be permitted on any lot containing a single-family dwelling, defined as a second dwelling unit with independent living facilities that is at least 30% of the principal unit's floor area or 1,000 square feet, whichever is less.

Municipal zoning ordinances would be prohibited from requiring passageways between units, more than one parking space per ADU, familial relationships between occupants, minimum age requirements, separate utility billing, or periodic permit renewals.

Municipalities may opt out of some or all ADU requirements by a two-thirds vote of the governing body after holding a public hearing, stating reasons on record, and notifying the Division of Local Government Services within 15 days.

ADUs would not be considered new residential uses for calculating water and sewer connection fees unless constructed with a new single-family home or requiring separate utility connections.

ADUs built after January 1, 2022 would only count toward a municipality's affordable housing obligation as the equivalent of a studio apartment affordable to a one-person household.
