Not reliably on its own. New Jersey's Anti-Eviction Act spells out exactly how a notice has to be delivered to count, and email isn't on that list — which matters if a tenant ever stops paying the increase and the landlord needs the notice to hold up in an eviction case.
The statute's service paragraph reads:
"The notice in each of the foregoing instances shall specify in detail the cause of the termination of the tenancy and shall be served either personally upon the tenant or lessee or such person in possession by giving him a copy thereof, or by leaving a copy thereof at his usual place of abode with some member of his family above the age of 14 years, or by certified mail; if the certified letter is not claimed, notice shall be sent by regular mail." (N.J.S.A. 2A:18-61.2)
That gives three ways to serve a qualifying notice — and only three:
Email, text message, and a notice taped to the door are simply not on that list.
A rent increase in New Jersey is structured as terminating the existing tenancy and offering a new one at the higher rent (N.J.S.A. 2A:18-61.1(f)). If the tenant stays without paying and the landlord ends up filing an eviction suit for nonpayment, the landlord has to be able to show the required notice was validly served. Because the statute lists specific delivery methods and email isn't among them, a notice sent only by email creates real uncertainty about whether that requirement was met — a court could find the service didn't satisfy N.J.S.A. 2A:18-61.2 even if the tenant actually read the email. This page doesn't review individual situations; if a specific notice's validity is in question, that's a question for a licensed New Jersey attorney.
Landlords commonly serve the notice through one of the three statutory methods — most often certified mail with a regular-mail follow-up, since it creates a paper trail without requiring an in-person visit — and separately send a courtesy copy by email or text so the tenant sees it sooner. Sending a courtesy email doesn't hurt, and it isn't prohibited; it just isn't a substitute for serving the notice in one of the ways the statute actually requires.
There's a practical difference between emailing a tenant a lease-renewal offer at a higher rent, which the tenant is free to sign or decline, and serving the formal termination notice a landlord needs on file to support an eviction if the tenant stays without paying. Many tenants simply sign a renewal that arrives by email and the delivery-method question never comes up. The statutory service rules become important specifically when a landlord may need to rely on the notice in court.
The Anti-Eviction Act, including this notice framework, does not apply to owner-occupied premises with two or fewer rental units. Those fall under the older, general dispossess statute (N.J.S.A. 2A:18-53) and a different notice-period scheme instead — see the exemptions guide for more on how that changes things.
N.J.S.A. 2A:18-61.2 is the statewide floor. A number of municipalities with local rent control layer on a longer notice period, a specific form, or a copy to the rent leveling board. A few examples from this site's town data, each with its own stated notice period:
