Newark, NJ Accessory Structures: ADU Owner Occupancy (2026)

Under Newark's conditional-use standards in Chapter 41:6, an ADU is permitted only where (a) the principal dwelling and the ADU remain in common ownership, and (b) the owner of record occupies either the principal dwelling or the ADU as a primary residence. The ordinance also bars any subdivision that would separate the ADU from the principal residence onto its own lot, meaning the two units cannot be sold individually. This owner-occupancy rule is a continuing condition of the conditional-use approval, not a one-time threshold: if the owner moves out and rents both units, the ADU loses its conditional-use status and becomes an illegal dwelling unit subject to enforcement under Chapter 41 (zoning) and Chapter 18:17 (Rental Property Registration). New Jersey has no statewide ADU statute, so Newark may impose owner-occupancy without preemption concerns. Owners are typically required to record a deed restriction or covenant memorializing the occupancy requirement as a condition of Planning Board approval. Death or sale of the property does not extinguish the requirement; the successor owner must take up residence in one of the two units or cease using the accessory unit.
