New Jersey Security Deposit Law: Limits, Deadlines, and Penalties
What New Jersey landlords can charge, when deposits must be returned, and what it costs to get it wrong. Last reviewed 2026-08-12.
How much can a landlord charge in New Jersey?
The Rent Security Deposit Act caps deposits at one and one-half times the monthly rent. If rent increases, any additional deposit collected in a given year cannot exceed 10 percent of the current deposit. Owner-occupied buildings with no more than two rental units are exempt unless the tenant demands coverage by 30 days' written notice.
New Jersey has no separate pet deposit statute; any pet deposit is part of the security deposit and counts toward the 1.5-month cap.
When must the deposit be returned?
The deposit plus the tenant's share of accumulated interest, less lawful deductions, must be returned within 30 days of termination by personal delivery, registered, or certified mail. The deadline shortens to five business days if the tenant is displaced by fire, flood, condemnation, or evacuation, and to 15 business days when the lease is terminated because of domestic violence.
Any deductions must be listed in an itemized statement of interest and charges that accompanies the returned balance, delivered personally or by registered or certified mail.
What happens if a landlord misses the deadline?
A tenant can sue for double the amount of deposit money wrongfully withheld, plus full court costs and, at the court's discretion, reasonable attorney's fees. Separately, failing to invest the deposit or give required notices lets the tenant order the deposit applied to rent.
Interest and holding requirements
Deposits must earn interest for the tenant, paid or credited annually. Landlords with 10 or more units must use an insured money market fund or interest-bearing account in a New Jersey institution; landlords with fewer than 10 units may use an ordinary interest-bearing account in a New Jersey bank. The rate is whatever the account actually earns — there is no fixed statutory rate.
The deposit must be held in a New Jersey banking institution, not commingled with the landlord's funds, and within 30 days of receipt the landlord must give written notice of the bank's name and address, the type of account, the interest rate, and the amount — with re-notice annually, at each interest payment, and on any transfer.
What New Jersey landlords get wrong
New Jersey is one of the most procedural deposit states for small landlords: the 30-day bank-disclosure notice and the annual interest payment with re-notice are where most violations happen, not the refund itself. If you skip the notices or never move the deposit into a proper New Jersey account, the tenant can serve written notice directing the deposit be applied to rent — and you then cannot collect a replacement deposit. Live-in landlords of two-unit buildings are exempt, but only until a tenant invokes the Act with 30 days' written notice. Use certified mail for the refund and itemization to prove timing.

Frequently asked questions
How much security deposit can a landlord collect in New Jersey?
One and one-half months' rent, maximum. When rent goes up, the landlord may collect additional deposit, but no more than 10 percent of the current deposit in any year. Pet deposits count toward the same cap. Owner-occupied buildings of two or fewer rental units are exempt unless the tenant demands coverage in writing with 30 days' notice.
Do New Jersey landlords have to pay interest on security deposits?
Yes. The deposit must sit in an interest-bearing account or qualifying money market fund at a New Jersey institution, and the interest belongs to the tenant, paid in cash or credited toward rent each year. There is no fixed rate — the tenant gets what the account earns. Landlords with fewer than 10 units can use a regular interest-bearing bank account.
How long does a New Jersey landlord have to return a security deposit?
Thirty days after the tenancy ends, by personal delivery or registered or certified mail, including the tenant's share of interest and an itemized statement of any deductions. Displaced tenants — fire, flood, condemnation, or evacuation — must be paid within five business days, and domestic violence lease terminations within 15 business days.
What happens if a New Jersey landlord doesn't return the deposit or pay interest?
Wrongfully withheld money exposes the landlord to double damages plus court costs and possibly attorney's fees. Separately, if the landlord never invested the deposit properly or failed to send the required bank notices, you can give written notice ordering the deposit plus 7 percent annual interest applied to your rent, and the landlord loses the right to collect another deposit.
