How to Keep Track of Security Deposits by State

Security deposits are one of the most legally regulated areas of landlording — and one of the easiest places to make a costly mistake. Every state has different rules on how much you can collect, where you must store it, and how quickly you need to return it. Get it wrong and you could owe the tenant double or triple the deposit amount in penalties.

This guide covers the key rules you need to know and how to build a tracking system that keeps you compliant.

Key Rules That Vary by State

Deposit limits: Some states cap deposits at one month's rent (California), others allow two months (New York for unregulated units), and some have no limit at all (Texas). Return timelines: California requires return within 21 days. Texas: 30 days. Florida: 15 days if no deductions, 30 if deductions are claimed. Storage requirements: Some states require deposits be held in a separate escrow account. Others require you to pay interest on the deposit.

What to Track for Each Deposit

For every security deposit, record: the amount collected, the date collected, the bank account where it's held, the tenant's name and unit, and the state-required return deadline (calculated from the move-out date). When the tenant moves out, document the property condition with photos, create an itemized deduction list if applicable, and return the balance within your state's deadline.

The Cost of Getting It Wrong

In many states, failing to return a deposit on time or failing to provide an itemized statement means you forfeit your right to keep any of it — even if the tenant caused real damage. Some states add penalties of 2x or 3x the deposit amount. A $1,500 deposit mishandled could cost you $4,500 or more.
