ADU rules in Hackensack, NJ — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Hackensack regulates accessory dwelling units through its zoning code, with permissions varying by district. Most single-family residential zones do not permit standalone ADUs without variance approval from the Zoning Board of Adjustment.

Property owners pursuing an ADU must apply through the Zoning Board of Adjustment under N.J.S.A. 40:55D-70(d), demonstrating special reasons and minimal detriment to the zone plan. Internal apartments in two-family or multi-family zones may be permitted by right where the lot meets minimum area, parking, and bulk requirements. All ADUs require building permits, plumbing, electrical, and certificate of occupancy inspections under the New Jersey Uniform Construction Code. Owner-occupancy and rental registration requirements may apply.
Unpermitted ADUs face stop-work orders, daily fines up to $2,000, removal orders, and loss of certificate of occupancy under municipal enforcement.
