How to register as a landlord in Union

New Jersey's New Jersey Landlord Registration / Identity Law (N.J.S.A. 46:8-27 to 46:8-37) applies statewide, so the registration requirement is the same in Union as it is everywhere else in New Jersey. It requires landlords to file a certificate of registration identifying who owns and manages the property and who to reach in an emergency.

Where to file

  • One-unit rentals, and two-unit non-owner-occupied properties: Municipal clerk of the town where the property is located (or the official the clerk designates).
  • Three or more units (multiple dwellings): NJ DCA Bureau of Housing Inspection.
  • Single- and two-family rentals (2007 amendment): Owners of tenant-occupied single-family and two-family properties must also file a registration with the DCA Bureau of Housing Inspection (46:8-28.5), with limited exceptions (e.g., certified lead-free or post-1978 owner-occupied two-family, seasonal rental under 6 months).

Key obligations

  • File within 30 days, or at creation of the first tenancy in a newly constructed/reconstructed building (46:8-28).
  • Give each tenant a copy of the registration certificate at the start of a new tenancy (46:8-29).
  • File an amended certificate within 20 days of any change to the form's information (46:8-28.2).

If you don't register

In an action for possession by a non-compliant landlord, no judgment for possession until registration; the court continues the case up to 90 days, then dismisses (46:8-33). Penalty up to $500 per offense (46:8-35); tenant rights cannot be waived (46:8-36).

Certificate of occupancy / rental inspection in Union

N.J.S.A. 40:48-2.12a and 40:48-2.12m authorize municipalities to require a certificate of inspection or occupancy for residential rental property prior to a new occupancy. This is why the requirement exists town-by-town rather than as one statewide process.

Program
Rental certificate of occupancy (Code Ch. 447, Rental Property); the township also issues a residential Certificate of Continued Occupancy (CCO)
Office

When it's triggered
Change of occupancy of a MULTIFAMILY rental, which Chapter 447 Article I defines as a building or buildings comprising 20 or more separate dwelling or apartment units (§ 447-9). § 447-1: all such buildings and units leased or rented, regardless of term, shall be inspected by the code official on every initial occupancy or change of occupancy. § 447-4: no tenant shall occupy until a rental certificate of occupancy has been issued.
What to know
READ THE SCOPE FIRST: the ordinance's change-of-occupancy rental CO reaches buildings of 20 or more units, not every rental house. Inspection is limited to once per unit biannually; the fee is $75 per apartment inspection including one re-inspection, with $50 for each additional re-inspection (§ 447-10). Separately, the Building Department runs a Rental Property Registration and issues a residential Certificate of Continued Occupancy; the published residential CCO procedure fetched here is written for a RESALE ($175 inspection fee, $80 per re-inspection, requested at least 10 business days ahead, issued two business days after final approval, valid three months and void if occupancy or ownership changes in the interim), and its stated purpose is verifying smoke detectors, carbon monoxide alarms and fire extinguishers. Whether a rental of fewer than 20 units needs a CCO on tenant turnover is NOT settled by these sources - confirm with the Building Department at 908-851-8509. Union Township, Union County (07083) is a different municipality from Union City, Hudson County, and from Union Township, Hunterdon County.
