How to register as a landlord in Trenton

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 Trenton 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).
