Interest Is Owed Annually: Your landlord must pay you the interest on your security deposit every year — either as a direct payment or as a credit toward rent. If they never paid you annual interest during your tenancy, you are owed that accumulated interest when you move out, in addition to the principal deposit.

New Jersey Security Deposit Law — Explained

The 30-Day Return Deadline

Under N.J.S.A. 46:8-21.1, New Jersey landlords must return the full security deposit — or provide a written itemized statement of deductions and the remaining balance — within 30 calendar days of the tenant vacating. Each deduction must be specifically itemized; lump-sum charges are not acceptable. Landlords who miss this deadline risk the double-damage penalty regardless of whether they had legitimate deductions.

The 1.5-Month Cap and Annual Increase Limit

New Jersey caps the initial security deposit at 1.5 months' rent. Landlords may increase the deposit annually, but any single-year increase is capped at 10% of the current deposit amount. If your landlord raised your deposit by more than 10% in any given year, the excess is unlawful and must be returned. Always review your deposit history when calculating your total refund claim.

Mandatory Interest on Deposits

New Jersey's security deposit law includes one of the strongest interest-protection requirements in the nation. Landlords must invest deposits in an interest-bearing money market account or similar instrument and pay the tenant the earned interest annually — either directly or as a credit against rent. The rate is pegged to the bank account rate, which varies year to year.

If your landlord never paid you annual interest during your tenancy, all of that accumulated interest is owed to you at move-out on top of your principal deposit. For long-term tenants, this can be a meaningful amount — track your tenancy start date and calculate accordingly.

Allowable Deductions

New Jersey landlords may deduct for unpaid rent, damage beyond normal wear and tear, and documented breach-of-lease costs. Normal wear and tear — minor scuffs, small nail holes, routine carpet wear — cannot be deducted. All deductions must be specifically itemized with receipts or cost documentation in the written statement sent within 30 days of move-out.

Double Damages and Attorney Fees

Under N.J.S.A. 46:8-21.1, a landlord who wrongfully withholds any portion of a deposit — or fails to send the required itemized statement within 30 days — is liable for double the wrongfully withheld amount plus reasonable attorney fees. New Jersey courts take these violations seriously; landlords cannot avoid the penalty by claiming clerical errors or oversight.

What to Do If Your NJ Landlord Is Late

  1. 1

  3. 3
    Calculate all interest owed If you never received annual interest payments during your tenancy, total up what was owed each year — this amount is part of your refund claim.
  4. 4
    Wait 30 days and watch for the itemized statement If neither your deposit nor an itemized statement arrives by Day 30, the deadline has been missed.
