The 2024 NJ ADU mandate (N.J.S.A. 52:27D-123.16) requires municipalities to allow ADUs by right on lots with single or two-family homes, with no owner-occupancy requirement, parking minimums waived, and ministerial processing (no discretionary review, deemed approved if not acted on within 60 days). Chapter 223 (LDO, amended 2019) implements local ADU rules. All ADUs require building permits and a Certificate of Occupancy under Chapter 426 (Building Construction Standards). Given Union City's extreme density and existing multi-family character, ADU implementation requires zoning office consultation. Contact Union City Zoning/Building at (201) 348-5731.
Unpermitted ADU: stop-work order, mandatory permits, fines.
