How much can my landlord raise the rent in New Jersey?

Start with your town

Rent control in New Jersey is local. A municipality may adopt an ordinance that limits how much and how often rent may rise, and a local rent control or rent leveling board enforces it. The Department of Community Affairs (DCA) publishes a Rent Control Survey that lists municipalities reporting such an ordinance. The survey is a starting point only. DCA itself tells tenants to confirm with the municipal clerk or the local rent board, because an ordinance may cover some buildings and exempt others, and the percentages on the survey may be out of date.

Common exemptions in local ordinances include small owner-occupied buildings. State law also exempts many newly constructed multiple dwellings from local rent control for 30 years after construction is completed, and a landlord claiming that exemption must tell a prospective tenant before the lease is signed (N.J.S.A. 2A:42-84.2 to 2A:42-84.6). Housing owned or subsidized by HUD or financed through the New Jersey Housing and Mortgage Finance Agency generally follows its own rent rules instead of the municipal ordinance.

To check your town, a tenant can (1) look up the municipality on the DCA Rent Control Survey, (2) call the municipal clerk and ask whether an ordinance exists and whether it covers the building, and (3) ask for a copy of the ordinance itself. Many municipal codes are also posted online by the municipality.

How an increase works when there is no rent control

Without a local ordinance, the process comes from the Anti-Eviction Act and case law. DCA describes it this way in its Truth in Renting guide and Rent Increase Bulletin:

• The landlord generally may not raise the rent during a lease term. The current tenancy has to end first.
• The landlord serves a written notice to quit (a notice that ends the current tenancy) together with a notice of rent increase. In this setting, the notice to quit tells the tenant that the tenancy may continue at the new rent. DCA states the notice to quit must be served at least one month before an eviction case is filed on this ground.
• If the tenant stays after the old term ends, DCA guidance says a new tenancy at the increased rent is created.
• If the tenant does not pay the increased amount, the landlord may file a case in the Superior Court, Special Civil Part, for nonpayment of the increase under N.J.S.A. 2A:18-61.1(f).

What "unconscionable" means

The statute does not define the word. Courts have filled in the gap. In Fromet Properties, Inc. v. Buel, 294 N.J. Super. 601 (App. Div. 1996), the Appellate Division listed factors a judge may weigh: the size of the increase, the landlord's expenses and profit, how the old and new rents compare with similar rentals nearby, the relative bargaining position of the two sides, and whether the increase would shock the conscience of a reasonable person. DCA guidance adds that the landlord carries the burden of proving the increase is fair and not unconscionable. There is no fixed percentage. A judge decides each case on its facts.

DCA guidance states that a tenant who believes an increase is unconscionable may withhold only the difference between the old rent and the new rent, and should keep paying the old rent. If the court rules for the landlord, the tenant then has to pay the increase to avoid eviction. That is a real risk, which is one reason to get legal advice before withholding anything.

Where rent control exists

In a rent-controlled unit, the ordinance sets the allowed increase, and the Anti-Eviction Act requires the increase to comply with it (N.J.S.A. 2A:18-61.1(f)). A tenant who believes an increase exceeds the ordinance, or who did not receive proper notice, may file a complaint with the local rent board where one exists, according to DCA.

Condo and co-op conversions

When a rental building converts to condominiums, cooperatives, or fee simple ownership, a landlord may not use costs that come solely from the conversion (such as new financing costs) to justify a rent increase, unless those costs add new services or amenities (N.J.S.A. 2A:18-61.31). That limit applies to all tenants in the building. Tenants who are 62 or older, or permanently disabled, and who meet income and residency requirements may qualify for protected tenancy under the Senior Citizens and Disabled Protected Tenancy Act (N.J.S.A. 2A:18-61.22 to 2A:18-61.39). In a rent-controlled municipality, a protected tenant's increase may not exceed what the ordinance allows for rent-controlled units (N.J.S.A. 2A:18-61.31). Applications generally go to the designated municipal official or administrative agent within 60 days of the converter's notice.

The FAIR Act and rent-setting software

On July 20, 2026, New Jersey enacted the Forbidding the Algorithmic Inflation of Rent (FAIR) Act (P.L. 2026, c.43). It makes it a violation of the New Jersey Antitrust Act for landlords to pay for or use a "coordinator" that sets or recommends rents using shared, nonpublic data from competing landlords, and it bars related coordination practices. The Attorney General must set up an online complaint location and may adopt rules. The law takes effect on the first day of the twelfth month after enactment, which is July 1, 2027 (P.L. 2026, c.43, § 9). Until then, its prohibitions are not yet in force. The FAIR Act sets no rent cap of its own.

What this page cannot do

This page explains what the law says. It does not tell anyone whether a particular increase is lawful, whether to pay it, or whether to withhold. Those questions depend on the lease, the town, the building, and the facts. If you can afford a lawyer, hire one. Really. Legal Services of New Jersey (1-888-576-5529) and county legal services programs may help people who qualify.

Your town matters more than the state

New Jersey left rent control to its 564 municipalities. Some have it. Most don't. DCA keeps a Rent Control Survey listing towns that report an ordinance. Use it as a lead, then call your municipal clerk. Ask two questions: does an ordinance exist, and does it cover your building? Ask for a copy. Ordinances carve out exemptions, and the survey's numbers can be stale.

One big carve-out comes from state law. Many newly built multifamily buildings are exempt from local rent control for 30 years after construction, and the landlord has to tell you before you sign (N.J.S.A. 2A:42-84.2 to 2A:42-84.6). HUD and HMFA housing usually runs on its own rent rules too.

No rent control? Here's the process

• Your landlord generally can't raise rent mid-lease.
• They serve a notice to quit plus a notice of rent increase. Scary name. In this case it tells you that you can stay at the new rent. DCA says it has to come at least one month before they can file in court on this ground.
• Stay past the end date and, per DCA, you're in a new tenancy at the new rent.
• Don't pay the increase and your landlord can file in Special Civil Part for nonpayment of it (N.J.S.A. 2A:18-61.1(f)).

The word doing all the work

The law never defines "unconscionable." Courts do. In Fromet Properties v. Buel, 294 N.J. Super. 601 (App. Div. 1996), the court listed what a judge can look at: how big the jump is, your landlord's costs and profit, what similar places nearby charge, who has more bargaining power, and whether the increase would shock a reasonable person. No magic percentage exists. A judge decides. DCA says the landlord has to prove the increase is fair.

DCA also says a tenant who thinks an increase is unconscionable can hold back just the difference and keep paying the old rent. If the judge sides with the landlord, you pay the increase or face eviction. That's a real gamble. Talk to a lawyer before you try it.

Rent-controlled? The ordinance sets the number

The increase has to follow your town's ordinance (N.J.S.A. 2A:18-61.1(f)). DCA says you can complain to your local rent board if an increase goes over the limit or the notice was wrong.

Building going condo?

Your landlord can't use conversion costs, like new financing, to justify a raise unless those costs add services or amenities (N.J.S.A. 2A:18-61.31). That covers everyone in the building. If you're 62 or older, or permanently disabled, and meet income and residency rules, you may qualify for protected tenancy (N.J.S.A. 2A:18-61.22 to 2A:18-61.39). In a rent-controlled town, a protected tenant's increase can't exceed the ordinance limit. The application window is short, generally 60 days from the converter's notice.

The FAIR Act, eventually

In July 2026, New Jersey banned landlords from paying for software that sets rents using competitors' private data (P.L. 2026, c.43). It's treated as an antitrust violation, and the Attorney General has to take complaints online. The catch: it takes effect July 1, 2027. So the robots get about nine more months. And it sets no cap on rent.
