If you're holding your tenant's security deposit in your personal checking account right now — you're breaking NJ law. And your tenant can sue you for double the deposit.
I manage 1,200+ doors across New Jersey and security deposit violations are one of the most common and most expensive mistakes I see landlords make. Not because they're trying to do something wrong — but because most landlords simply don't know what the law requires. Here are the five rules every NJ landlord must follow.
Important: This guide is for informational purposes only and is not legal advice. Consult a NJ landlord-tenant attorney for your specific circumstances.
The 5 NJ Security Deposit Rules
The deposit must be held in a separate NJ bank account. Not your personal checking. Not your business operating account. A separate account established specifically for security deposits at a New Jersey bank or financial institution. Commingling deposit funds with your own money is a direct violation of the NJ Security Deposit Law.
You must pay interest on the deposit annually. NJ law requires landlords to pay interest on security deposits every year. The rate is tied to what the holding bank pays on the account. You must either pay the interest directly to the tenant or credit it toward rent. Skipping this step — even once — is a violation.
You must notify the tenant in writing within 30 days. Within 30 days of receiving the security deposit, you must notify the tenant in writing of the bank name, branch address, and account number where the deposit is being held. If you move the deposit to a different bank, you must notify the tenant again within 30 days of the transfer.
You have 30 days to return it after move-out. When a tenant vacates, you have 30 days to return the security deposit along with an itemized written statement of any deductions. If the tenancy was terminated due to fire, flood, or other casualty, the deadline shortens to 15 days. Missing this deadline — even by one day — can expose you to double damages.
Violations mean double damages plus attorney fees. If you violate any provision of the NJ Security Deposit Law, your tenant has the right to sue for double the amount of the deposit plus reasonable attorney fees. A $2,000 deposit violation can cost you $4,000 plus legal fees before the case is even over.
The Most Common Violations I See
- Holding the deposit in a personal account — the most frequent mistake. Many landlords simply don't know a separate account is required.
- Not paying annual interest — easy to forget, expensive when challenged.
- Not notifying the tenant of the bank and account — required within 30 days of receipt, not just at move-in.
- Missing the 30-day return deadline — sometimes landlords wait for a contractor estimate before returning the deposit. The clock doesn't wait.
- Deducting for normal wear and tear — you can only deduct for damage beyond normal wear and tear. Routine cleaning, minor scuffs, and standard wear are not deductible.
What This Means for Multifamily Investors
In a multifamily building, security deposit compliance is multiplied across every unit. One violation per tenant can compound quickly. I track security deposit accounts, annual interest payments, and move-out timelines for every unit on every property I manage. It's in every monthly owner report. Owners never have to think about it.
For out-of-state investors especially — NJ security deposit law is not something to manage from another state without experienced local support. The 30-day return deadline doesn't care where you live.
