New Jersey Security Deposit Law, in Plain English

New Jersey treats a deposit as the tenant's money on loan: capped, banked in the tenant's interest, disclosed in writing, and returned in 30 days — or doubled by a judge who has no discretion to do otherwise. It also hands tenants an unusual weapon when the landlord skips the paperwork. Here's how the Rent Security Deposit Act (N.J.S.A. 46:8-19 to 26) actually works, for both sides of the lease.

1.5 months' rent — and a 10% speed limit on increases

A New Jersey landlord may collect no more than one and a half months' rent as security. When rent rises, the deposit may rise with it — but by no more than 10% of the deposit per year, no matter how big the rent increase.

The Act's account and interest rules (below) skip owner-occupied buildings of three or fewer units — unless the tenant serves a written 30-day notice electing coverage. The 30-day return rule and the doubling penalty apply regardless.

The tenant's money, in the tenant's interest — disclosed in writing

The deposit must be held in an interest-bearing account at a New Jersey bank or savings institution — a money-market fund for landlords with ten or more units, a savings or insured account for smaller landlords. The interest belongs to the tenant, paid or credited to rent annually; the landlord may keep a 1% administrative fee where the Act permits it.

Within 30 days of receiving the deposit — and again with each annual interest payment, and whenever the bank or the building's ownership changes — the landlord must notify the tenant in writing of the institution's name and address, the account type, the current interest rate, and the amount held.

Skip that notice and the tenant gets a remedy most states don't offer: written notice applying the deposit plus interest to rent, after which the landlord may not demand a new deposit for the rest of the lease. A missed form letter can turn into a month and a half of free rent.

After move-out: 30 days, itemized, by certified mail

Within 30 days of the lease ending, the landlord must return the deposit plus the tenant's share of interest, less lawful deductions, by personal delivery, registered mail, or certified mail. Deductions must be itemized, and the tenant notified of them by registered or certified mail — a plain envelope doesn't satisfy the statute.

What can be deducted: charges expended under the lease — unpaid rent and repair of damage beyond normal wear and tear. Faded paint, carpet worn by ordinary use, the nail holes from hanging a mirror: the landlord's cost.

Two situations shorten the clock. A tenant displaced by fire, flood, condemnation, or evacuation gets the deposit back within 5 days. A tenant ending the lease as a victim of domestic violence gets it within 15 business days.

When it goes wrong: the doubling isn't optional

N.J.S.A. 46:8-21.1 is unusually blunt: when a court finds the landlord wrongfully withheld any part of the deposit, it shall award double the amount wrongfully withheld, plus court costs — and, at the judge's discretion, reasonable attorney's fees. A landlord who simply misses the 30-day deadline is exposed to the same arithmetic. The doubling applies to the amount withheld, not automatically the whole deposit, but on a full-deposit dispute that distinction disappears.

Deposit suits go to the Superior Court's Special Civil Part — the Small Claims Section for disputes up to $5,000, the Special Civil Part itself up to $20,000. Filing is cheap and lawyers are optional. What decides the case is paper: the lease, the bank notice or its absence, the certified-mail itemization, and dated room-by-room photos from both ends of the tenancy.

Frequently asked questions

How long does a landlord have to return a security deposit in New Jersey?

30 days after the lease ends. The landlord must return the deposit plus your share of the interest, minus itemized deductions, by personal delivery or registered/certified mail, and notify you of any deductions by registered or certified mail. Two exceptions shorten it: 5 days if you were displaced by fire, flood, condemnation, or evacuation, and 15 business days for domestic-violence lease terminations.

How much can a landlord charge for a security deposit in New Jersey?

No more than one and a half months' rent. If the rent goes up, the deposit can go up too — but by no more than 10% of the deposit per year.

Where does my deposit have to be kept, and do I get interest?

In an interest-bearing account at a New Jersey bank or savings institution — a money-market fund for landlords with ten or more units, a savings or insured account for smaller landlords. The interest is yours, paid or credited to rent annually (the landlord may keep a 1% administrative fee where the Act allows it). Within 30 days of paying, you must get written notice of the bank, account type, rate, and amount.

What if my landlord never told me where the deposit is held?

You can send the landlord written notice that you're applying the deposit plus interest to your rent — and the landlord can't demand a new deposit for the rest of the lease. It's one of the sharpest tenant remedies in the Act, and it depends entirely on the landlord skipping a 30-day notice.

What can a landlord deduct from a deposit in New Jersey?

Charges expended under the lease — unpaid rent and repair of damage beyond normal wear and tear — itemized in writing. Ordinary aging like faded paint or normally worn carpet isn't deductible.

What happens if the landlord misses the 30-day deadline or wrongfully keeps money?

If you sue and win, the court must award double the amount wrongfully withheld, plus court costs and — at the judge's discretion — reasonable attorney's fees. The doubling is mandatory, which is why New Jersey landlords who miss the deadline usually settle quickly.

Does the Act apply to small owner-occupied buildings?

The account and interest rules don't apply to owner-occupied buildings with three or fewer units — unless the tenant serves a written 30-day notice electing coverage. The 30-day return rule and the doubling penalty still apply to the deposit itself.

Where do deposit disputes go in New Jersey?

The Small Claims Section of the Special Civil Part handles claims up to $5,000; larger claims (up to $20,000) go to the Special Civil Part. Bring the lease, the bank notice (or proof none arrived), the itemized deduction notice, and dated move-in and move-out photos.
