What are the security deposit rules in New Jersey?

Verified July 8, 2026 All New Jersey topics →

Check your municipality. New Jersey does not preempt local rent regulation — city or county ordinances may impose rent caps, notice rules, and fee limits that are stricter than the state-level rules on this page and are not covered here. Verify your municipality's ordinances before relying on any figure below.

What the state record says

New Jersey has no statewide rent control statute, but it is the leading NON-preemption state: municipalities have had confirmed authority to enact rent control since Inganamort v. Borough of Fort Lee, 62 N.J. 521 (1973), and roughly 100 New Jersey municipalities — including Newark, Jersey City, Elizabeth, Paterson, and Fort Lee — maintain rent control or rent leveling ordinances with their own caps, notice rules, and boards. State law also polices increases through the Anti-Eviction Act's unconscionability standard.

New Jersey caps security deposits at one and a half months' rent — and the cap counts every dollar of prepaid money however it's labeled, so a landlord cannot stack 'last month's rent' on top of a full deposit.

The deposit must sit in an interest-bearing account at a New Jersey institution with the bank details disclosed to the tenant within 30 days, annual interest paid to the tenant, and any renewal-time deposit increase limited to 10% per year. Within 30 days of move-out (5 days after fire, flood, or condemnation; 15 business days for domestic-violence lease terminations) the landlord must return the deposit with interest and a certified-mail or personally delivered itemization — and a landlord who misses the deadline or wrongfully withholds owes double the amount due, plus costs and often attorney's fees. One notable carve-out: the Act does not apply in owner-occupied buildings with two or fewer rental units unless the tenant opts in by 30 days' written notice.

New Jersey security deposits at a glance

Maximum deposit	1.5 months' rent — N.J.S.A. 46:8-21.2: no more than one and one-half times one month's rent. Critically, ALL prepaid money held to secure the tenancy counts toward the cap regardless of label — including 'last month's rent' (Brownstone Arms v. Asher; Reilly v. Weiss, as summarized in the official DCA Truth in Renting guide) — so a landlord may collect only the first month's rent plus 1.5 months as security at move-in. Any additional deposit collected on renewal is capped at 10% of the current deposit per year. Pet deposits are allowed only within the same combined 1.5-month ceiling.
Return deadline	30 days
Deadline conditions	Within 30 days after termination of the tenancy the landlord must return the deposit plus the tenant's portion of accumulated interest or earnings, less lawful deductions, with the itemization delivered by personal delivery, registered mail, or certified mail (N.J.S.A. 46:8-21.1). Accelerated deadlines: 5 days when the tenant is displaced by fire, flood, condemnation, or evacuation (with building-inspector certification mechanics), and 15 business days when a domestic-violence victim terminates the lease under N.J.S.A. 46:8-9.6. No deductions may be taken while the tenant remains in possession.
Itemization required	Yes
Itemization rules	Any deductions and the interest/earnings must be itemized and delivered by personal delivery, registered mail, or certified mail within the deadline. The statute does not enumerate permitted deduction categories; deductions must be 'charges expended in accordance with the terms of the contract, lease or agreement' plus rent due — in practice unpaid rent and damage beyond ordinary wear and tear.
Separate account required	Yes
Interest owed to tenant	Yes
Account & interest rules	Deposits must be placed in an interest-bearing account at a New Jersey state or federally chartered bank, savings bank, or savings and loan (landlords of 10 or more units may alternatively use qualifying insured money-market funds), with written notice to the tenant within 30 days of receipt — and again at each annual interest payment, on transfer, and on sale — of the institution's name and address, the account type, and the rate (N.J.S.A. 46:8-19). Interest or earnings belong to the tenant and are paid annually in cash or credited against rent. If the landlord fails to invest or provide the required notices, the tenant may give written notice directing that the deposit plus 7% annual interest be applied to rent, after which the landlord may not demand a new deposit. Seasonal tenancies of 125 days or less are excused from the interest-bearing-account requirement only — not from the return obligation (NJ App. Div., 2025).
Pet deposits	Permitted only within the combined 1.5-month cap of 46:8-21.2; per the DCA guide, a pet deposit that pushes the combined total above one and one-half months' rent is unlawful.
Non-refundable fees allowed	Not addressed by statute
Penalty for violation	In a tenant's action for return of moneys due, a court finding for the tenant SHALL award double the amount wrongfully withheld, together with full costs of the action and, in the court's discretion, reasonable attorney's fees (N.J.S.A. 46:8-21.1). Separate civil penalties of $500-$2,000 per offense apply to willful withholding of deposits made by state entities on a tenant's behalf. Courts apply the doubling to the net amount due — a landlord with legitimate partial deductions who simply misses the 30-day deadline still doubles the balance owed.
Tenant forwarding-address duty	Not addressed by statute

Notes and caveats

The prepaid-funds rule (all advance money counts toward the 1.5-month cap, per Brownstone Arms v. Asher and Reilly v. Weiss as stated in the official DCA guide) is the most commonly violated provision and belongs in the answer box. The 46:8-26 owner-occupied exemption (≤2 rental units, tenant may opt in with 30 days' written notice) is the small-landlord carve-out; tenants in exempt buildings must make written demand before suing. The 46:8-19 self-help remedy (deposit + 7% applied to rent on landlord's investment/notice default) is unique to NJ. nonrefundable_fees_allowed is null because no statute addresses non-refundable fees generally; fees that function as security are recharacterized under the prepaid-funds rule. Citation caveat: NJ's official legislature portal lacks stable statute deep links, so the code-mirror URL is marked official: false and the official DCA guide and 2025 Appellate Division opinion carry the official sourcing.

How this record was verified: Direct read of statute text of N.J.S.A. 46:8-21.1 (full text via the 2025 code mirror, corroborated by a 2025 NJ Appellate Division opinion on njcourts.gov construing 46:8-19 and 46:8-21.1), cross-checked against the New Jersey Department of Community Affairs' official 'Truth in Renting' guide (the state's authoritative landlord-tenant publication) for the 46:8-21.2 cap, prepaid-rent rule, 10% annual increase cap, pet-deposit rule, late-charge rules, and the 2A:42-6.1 protected-tenant grace period. New Jersey's official statute portal (njleg.state.nj.us) does not provide stable deep links to code sections, so section citations link to a code mirror where no official URL exists, with the official DCA guide and court opinion cited as official sources.
