Governed by the Security Deposit Law (N.J.S.A. 46:8-19) since its original enactment on January 1, 1968, New Jersey's security deposit regulations are among the most stringent in the nation, with strict requirements for how much a landlord can collect, where the money must be held, what interest tenants earn, and how quickly it must be returned.
Maximum Deposit Limit
Under N.J.S.A. 46:8-21.2, a landlord cannot collect a security deposit exceeding 1.5 times the monthly rent.
- If rent is $2,000/month, the maximum security deposit is $3,000.
- After the first annual lease renewal, the landlord may increase the deposit only by 10% of the prior deposit per year, regardless of whether the rent has increased more dramatically.
Mandatory Interest-Bearing Account
Unlike most states which simply require a separate account, New Jersey mandates that the deposit be held in an interest-bearing account at a New Jersey-based, FDIC-insured banking institution.
Within 30 days of receiving a deposit, the landlord must provide the tenant with a written notice identifying:
- The name and address of the banking institution.
- The type of account.
- The current interest rate.
Annual Interest Payment
The landlord must pay or credit the tenant with the accrued interest annually, either as a direct cash payment or as a credit on the next month's rent. Failing to pay interest entitles the tenant to apply the interest as a credit against their rent.
Return Timeline
If deductions are taken, the landlord must provide an itemized list of all damages and charges, along with the remaining balance.
Penalties for Wrongful Withholding
If a landlord fails to return the deposit or provide an itemized list within the required timeframe, the tenant can sue for:
- Double the amount of the wrongfully withheld deposit.
- Reasonable attorney's fees and court costs.
Tenants typically file these actions in the Small Claims Section (for amounts up to $5,000) or the Special Civil Part (for amounts up to $20,000) of the Superior Court in the county where the property is located.
Non-Refundable Fees New
Jersey does not recognize "non-refundable" security deposits. Any payment that functions as a security deposit (regardless of what the landlord labels it) is subject to the 1.5-month cap and all interest/return requirements. Application fees are generally not considered security deposits, but any fee paid as a condition of occupancy may be scrutinized by the courts.
Automate Your Deposit Compliance
Tracking annual interest payments, 30-day return windows, and 10% annual increase caps across a portfolio is a compliance nightmare. Landager automates your NJ deposit ledger, computing interest credits annually and preventing deposit increases that exceed the statutory 10% annual threshold.
Official Law Citation: New Jersey law limits residential security deposits to 1.5 months' rent and requires returning them within 30 days. (N.J.S.A. 46:8-21.1 and 46:8-21.2)

Frequently Asked Questions
▶What are the New Jersey security deposit rules and return deadlines?
New Jersey has specific rules governing how much landlords can charge for security deposits, how deposits must be held, and the deadline for returning deposits after a tenant moves out. Landlords must provide an itemized statement of any deductions made from the deposit. Failure to comply with deposit return deadlines can result in penalties and the forfeiture of the landlord's right to claim deductions.
▶What are the New Jersey landlord-tenant laws every property owner should know?
New Jersey is widely recognized as one of the most tenant-protective states in the nation. Unlike most states that allow no-cause evictions, NJ requires landlords to prove "good cause" to remove a tenant-even after a lease expires. Coupled with mandatory interest-bearing security deposit accounts, municipal-level rent control in approximately 117 municipalities, and a powerful implied warranty of habitability, managing rental properties in the Garden State demands meticulous legal compliance. This guide covers the essential compliance requirements for property owners and landlords.

The New Jersey eviction process requires landlords to provide written notice to tenants before filing a court action. The type and length of notice depends on the reason for eviction — typically shorter for non-payment of rent and longer for lease violations or no-fault terminations. Self-help evictions (changing locks, removing belongings, shutting off utilities) are illegal in New Jersey. The full court process varies but typically takes several weeks.

New Jersey has specific rules governing when and how landlords can increase rent. During a fixed-term lease, rent generally cannot be increased unless the lease explicitly allows it. For month-to-month tenancies, landlords must provide proper written notice before an increase takes effect. Check whether New Jersey has any local rent control ordinances that may impose additional caps or requirements.
Read the complete guide▶What is the grace period for late rent in New Jersey?
New Jersey has specific rules regarding grace periods for late rent and the amount that can be charged as a late fee.

Read the complete guide▶What are New Jersey landlord maintenance obligations and habitability standards?
