Security Deposits: Holding, Deducting and Returning

By the Prizm P.M. team at STS Automatic LLC · Last reviewed September 18, 2026 · 8 min read

More small-claims cases between landlords and tenants are about security deposits than about anything else, and most of them are lost on process rather than on merit. The landlord was right that the carpet was ruined, and still paid a penalty because the itemized statement went out four days late.

How much to collect

One month's rent is the common standard; many states cap deposits at one, one and a half, or two months, and a few restrict what you can collect on top (last month's rent, pet deposits, cleaning fees). Some cities are stricter than their state. Look up the cap where the property sits before you advertise a number.

Charging the maximum is not always smart. A deposit that prices out good applicants costs more in vacancy than it protects against damage.

Where the money lives

A security deposit is the tenant's money that you hold. Several states require it in a separate account, some require a specific type of account at an in-state institution, and some require you to pay the tenant interest annually. Even where none of that is required, keep deposits out of your operating account. Spending a deposit on repairs at another property is the fastest route to a bad month.

Many states also require written notice to the tenant within 30 days of where the deposit is held. Put that notice in the lease and keep the signed copy.

The move-in inspection is the whole ballgame

You cannot prove damage without a baseline. Before the tenant takes possession, walk the unit with a written checklist, photograph every room including floors, walls, appliances, counters and fixtures, and have both parties sign and date the checklist. Give the tenant a copy and keep the photos with timestamps intact.

Do the identical walkthrough at move-out, in the same order, with the same rooms. A side-by-side photo pair is worth more than any amount of description.

Normal wear and tear versus damage

The distinction is the one tenants dispute most, and it is not arbitrary: wear and tear is the deterioration that happens from ordinary living over time. You cannot charge for it.

• Wear and tear: faded paint, minor scuffs, small nail holes, worn carpet in traffic lanes, loose hinges, dingy grout.
• Damage: holes in drywall, pet urine in carpet padding, burns or large stains, broken fixtures, unapproved paint colors, removed appliances, excessive filth requiring more than standard cleaning.

Also account for useful life. If a carpet's expected life is ten years and it is destroyed in year eight, you may fairly claim the remaining two years of value, not a full replacement.

Returning it, on time and itemized

Deadlines run from 14 to 60 days depending on the state, and the clock starts at the end of the tenancy, not when you get around to the inspection. Missing it can forfeit your right to deduct anything and expose you to double or triple damages in some states.

Your return packet should contain:

1. An itemized statement with a line and dollar amount per deduction.
2. Copies of invoices or receipts for the work.
3. The move-in and move-out photos supporting each item.
4. A check or transfer for the remaining balance.

Send it to the forwarding address the tenant provided; if they left none, send it to the last known address and keep proof of mailing.

When the damage exceeds the deposit

Send the itemized statement showing the deposit fully applied and the remaining balance owed, with the same documentation. Ask for payment on a stated date, offer a plan if the amount is large, and only then consider small claims. Courts reward the landlord with photos, receipts and a signed checklist, and they are unimpressed by estimates with no paperwork behind them.

General information, not legal advice. Deposit caps, account rules, interest and return deadlines are set by state and sometimes city law — confirm yours before move-in.
