Security Deposit Laws by State: Caps, Deadlines & Deductions

A security deposit is money a landlord holds against unpaid rent and tenant-caused damage — but the moment a tenancy ends, that money is governed by strict rules on how much you could collect, how fast you must return it, what you may deduct, and how you must document it. Get those rules right and the deposit does its job quietly. Get them wrong — a late return, an unitemized deduction, a charge for normal wear and tear — and many states let the tenant recover a penalty of two or three times the deposit plus your attorney fees. This hub explains how deposit law works across the country, then links the exact rules for every state, the District of Columbia, and Puerto Rico.

The single fact that shapes everything below is that security deposit law is highly state-specific. Whether there is a cap on the deposit at all, how many days you have to return it, whether you must pay interest, whether the money must sit in a separate account, and how severely a wrongful withholding is punished all change from one state to the next. What does not change is the framework: a landlord may keep only what unpaid rent and real damage justify, must account for the rest in writing, and must return the balance by a legal deadline. Learn that framework here, then open your state’s page for the specific numbers — this hub deliberately does not repeat per-state figures, because the whole point of the state pages is to carry the exact statute for your jurisdiction.

Below, a short overview video frames how the pieces fit together; the sections that follow break down each rule — caps, the return deadline, itemization, allowable deductions versus wear and tear, interest and separate accounts, non-refundable fees, and penalties — and then the complete state index links the detailed law for all fifty-two jurisdictions.

Every state regulates security deposits, and while the specifics differ, the same seven questions decide almost every deposit situation: How much may you collect? Where must you keep it? Do you owe interest? What may you deduct? How fast must you return it? Must you itemize? And what does it cost you to get it wrong? Work through those questions in order, using your state’s page for the exact figures, and you will handle nearly any deposit correctly. The sections below walk each one.

The first rule is a ceiling on the deposit itself. Some states cap it at one or two months’ rent; a handful adjust the limit for older tenants, furnished units, or the presence of a pet; and many states set no statutory cap at all, leaving the amount to the lease and the local market. Where a cap exists, exceeding it can make the excess refundable on demand and, in some states, expose you to a penalty — so the amount you write into the lease is itself a legal decision. A growing number of states have also moved to limit combined move-in charges (first month, last month, and deposit together), which can constrain what looks like a lawful deposit when stacked with other up-front money.

Once the tenancy ends, a countdown starts. Most states require you to return the deposit — or the remaining balance after lawful deductions, along with the itemized statement — within a set number of days, commonly fourteen to thirty, though some allow forty-five or sixty. The clock usually begins when the tenant surrenders possession and returns the keys, not when the lease term technically ends. Miss the deadline and you can lose more than the argument: many states penalize a late return even when the deductions were perfectly valid, because the violation is the delay itself. Calendar the deadline the day the tenant hands back the keys, and treat it as immovable.

What you may subtract from a deposit is narrower than many landlords assume. In nearly every state you may deduct unpaid rent and the cost to repair damage the tenant caused beyond normal wear and tear; many states also allow cleaning needed to return the unit to move-in condition and other lease breaches the agreement spells out. What you may not deduct is normal wear and tear — the ordinary aging of a lived-in home. Charging for wear and tear is the most common deposit mistake and the fastest way to convert a routine move-out into a penalty case.

The line between the two columns is where most disputes live, and the states draw it slightly differently. When a charge is close to the line, documentation decides it — which is why the move-in and move-out record matters so much. Our guide on how to handle a security deposit dispute walks through defending a contested deduction, and the move-out checklist for landlords covers the inspection that produces the evidence.

Withholding any part of a deposit almost always triggers a paperwork duty. Most states require a written, itemized statement listing each deduction and its amount — frequently with receipts or good-faith estimates — delivered to the tenant within the same window that governs the return. The itemized statement is not a courtesy; in several states, skipping it forfeits the entire deposit even when the underlying charges were legitimate. Send the balance and the itemization together, keep proof of mailing, and describe each charge specifically rather than with a vague catch-all.

In some states and cities the deposit is not just yours to hold loosely. A number of jurisdictions require the deposit to sit in a separate escrow or trust account, apart from your operating funds, and to disclose to the tenant where it is held. Some — and certain cities such as Chicago — require you to pay the tenant interest on the deposit, either annually or at move-out, at a rate set by statute or ordinance. Many states impose neither rule. Because commingling or skipping required interest can itself trigger penalties independent of any deduction dispute, confirm your state’s account and interest rules before you deposit the money anywhere. Our overview of security deposit interest requirements covers which jurisdictions require it.

Landlords often try to convert part of the up-front money into a non-refundable cleaning or pet fee. Whether that works depends entirely on the state. Some states permit clearly labeled non-refundable fees so long as the lease says so and they are not disguised deposits; others prohibit them outright and treat every dollar a landlord holds against the tenancy as a refundable deposit subject to the return and itemization rules. Mislabeling a refundable deposit as a non-refundable fee — or bundling a fee into the deposit to dodge the cap — can expose you to the same penalties as any other wrongful withholding.

The reason all of the above matters is the penalty at the end. When a landlord withholds a deposit in bad faith, misses the return deadline, or fails to itemize, most states let the tenant recover far more than the disputed amount. The penalty is commonly a multiple of the deposit — frequently two or three times the sum wrongfully withheld — plus the tenant’s court costs and attorney fees. Because a modest deduction dispute can balloon into a judgment several times the deposit, the safe course is almost always to return the correct balance on time with a clear itemization, and to litigate only a charge you can fully document.

Almost every deposit outcome is set before move-out, at move-in. A dated, signed condition report with photographs establishes the unit’s baseline so that at the end you can prove what changed and separate tenant damage from pre-existing wear. Some states require a written move-in checklist, and several require a pre-move-out inspection with notice and a chance for the tenant to cure. Do the walk-through, document both ends, and the itemized statement at move-out becomes a summary of evidence you already hold rather than an argument you have to win from memory. The move-out checklist for landlords and the free landlord forms library cover the condition report, the itemization, and the return letter.

This page is the map, not the how-to. It frames the nationwide framework and links each state’s statute. When you need to do something specific, use the dedicated guides: how to handle a security deposit dispute walks through a contested deduction and a tenant demand letter; the move-out checklist for landlords covers the inspection and turnover; security deposit interest requirements details which jurisdictions require interest; and security deposit rules and screening tips ties the deposit to the tenant you choose. Start here for the framework, branch to a how-to for the task, and open your state’s page for the exact numbers.
