No, in New Jersey a landlord generally cannot evict someone “for no reason.” Even if a written lease agreement has expired or there’s no written lease, landlords must have “just cause” under the Anti‑Eviction Act (e.g., nonpayment of rent, lease violations, or other statutory grounds) and follow the proper legal eviction process in court.
If the landlord is ending a tenancy like month‑to‑month with lawful cause, they must give the appropriate written notice (for example, one month’s notice to terminate a month‑to‑month rental) before filing an eviction action.
In all cases, a landlord must obtain a court judgment for possession and cannot legally remove a tenant (such as changing locks or cutting off utilities) on their own.
