New Jersey security deposit law is detailed and strictly enforced. Getting it wrong can cost you double the amount you wrongfully withheld — plus the tenant’s attorney’s fees. Here’s what every NJ landlord needs to know.
Maximum security deposit in New Jersey
New Jersey law caps the security deposit at 1.5 times the monthly rent. This limit includes:
- Last month’s rent collected upfront (counts toward the total)
- Pet deposits
- Cleaning fees collected upfront
- Any other deposit-style payment
You cannot collect more than 1.5x monthly rent in total deposits, regardless of how you label the individual charges. Attempting to structure around this limit — for example, calling a portion an “amenity fee” while functionally treating it as a deposit — is a violation.
Where must the security deposit be held?
New Jersey law requires that security deposits be held in a separate, interest-bearing account at a New Jersey bank, savings bank, or savings and loan association insured by a federal agency. The deposit must be:
- Separate from your personal funds — commingling is not permitted
- In an interest-bearing account — not a standard checking account
- At a NJ-based institution — out-of-state banks do not qualify
You have two account options:
- A traditional interest-bearing bank account at a NJ institution
- Shares in an insured money market fund established by a New Jersey-based investment company

- The name and address of the bank
- The account number
- The amount deposited
Failure to provide this notice is itself a violation of NJ security deposit law.
Annual interest payments
The interest earned on the security deposit belongs to the tenant. You must pay it to them each year — either as a direct payment or as a credit against rent. This is not optional.
Deposit return timeline
| Situation | Return deadline |
|---|---|
| Normal lease end | 30 days after the tenant vacates |
| Fire, flood, or condemnation | 5 banking days |
The clock starts when the tenant vacates and provides a forwarding address. You must return the deposit (or the remaining balance after documented deductions) within the applicable deadline.
Allowable deductions
You may only deduct from the security deposit for:
- Unpaid rent
- Actual damage beyond normal wear and tear
You cannot deduct for ordinary wear and tear — minor scuffs on walls, small nail holes, carpet wear from normal use. Deductions must be documented with an itemized statement.
Required itemized statement
If you’re keeping any portion of the deposit, you must provide the tenant with:
- An itemized written statement of the deductions
- The remaining balance returned with the statement
- Within the same 30-day deadline
Penalties for violations
NJ security deposit law carries real teeth:
- Failure to return within 30 days: Tenant can sue for double the amount wrongfully withheld, plus court costs and attorney’s fees
- Commingling with personal funds: Violation of the law; tenant can demand immediate return
- Failing to pay annual interest: Tenant can deduct the interest from rent
- Exceeding the 1.5x cap: Tenant entitled to immediate return of the excess
Frequently asked questions
Can I use the security deposit as last month’s rent in NJ?
No. NJ law explicitly prohibits using the security deposit as last month’s rent unless the tenant and landlord agree to it in writing at the time of termination. If last month’s rent is collected at move-in, it counts toward the 1.5x cap.
What if the tenant doesn’t provide a forwarding address?
The 30-day clock may not start until you have a forwarding address. However, you should still make a good-faith effort to return the deposit. Document your attempts.
Does the security deposit limit apply to month-to-month tenancies?
Yes. The 1.5x limit applies to all residential tenancies in New Jersey, regardless of term length.
