New Jersey Lease Extension Addendum

This Lease Extension Addendum is built with New Jersey as the governing state. These are the New Jersey landlord-tenant rules that most often bear on it, with the statute for each.

New Jersey rules at a glance

New Jersey rules for a Lease Extension Addendum
Ending a tenancyStatutory good cause required — no at-will non-renewal (owner-occupied premises with ≤2 rental units excepted)N.J.S.A. 2A:18-61.1
Rent increasesNo statewide cap or fixed day count; must follow a valid notice to quit and not be unconscionableN.J.S.A. 2A:18-61.1(f)
Rent controlNo state law — set by individual municipal ordinances (roughly 100 towns)

Rent, late fees & rent increases

  • Late fees — New Jersey sets no general dollar or percentage cap. A late fee should be stated in the lease and reasonable in amount; courts can refuse to enforce an excessive one.
  • Senior & benefits grace period — Where rent is due on the first of the month, a tenant who is a senior citizen receiving Social Security or an equivalent government pension, or who receives Social Security Disability, SSI or WorkFirst NJ benefits, gets a 5-business-day grace period before any late charge (N.J.S.A. 2A:42-6.1, -6.3). This is not a universal grace period.
  • Rent increases — Rent can’t be raised mid-lease. To increase it, the landlord serves a written notice to quit and notice of rent increase that ends the current term and offers a new tenancy at the higher rent; the tenant may stay by paying it. The notice must end the current term — at least one month for a month-to-month tenancy — and the increase must not be unconscionable (N.J.S.A. 2A:18-61.1(f)).
  • Rent control — The State doesn’t cap rents, but roughly 100 municipalities have rent-control or rent-leveling ordinances that limit the size and timing of increases. Newly built multiple dwellings can be exempt from local rent control for up to 30 years, or the amortization period of the initial mortgage if shorter (N.J.S.A. 2A:42-84.2).
  • Application fees — From May 1, 2026, application and similar fees are capped at $50, adjusted yearly for inflation; units in owner-occupied one- and two-family homes are exempt (P.L.2025, c.405).
