Security Deposit Deductions: What Landlords Can Legally Deduct (2026 Guide)

A landlord can deduct unpaid rent, damage beyond normal wear and tear, cleaning needed to restore move-in condition, unreturned keys, removal of abandoned property, and unpaid utility balances the tenant owed under the lease. You cannot deduct for ordinary aging of the unit, routine turnover costs, pre-existing damage you never documented, or upgrades.

Miss any one of those and the deduction usually fails, even when the damage was genuine. In many states, missing the deadline alone forfeits your right to deduct anything and exposes you to penalties of two or three times the deposit plus the tenant's attorney fees. The rest of this guide covers the wear-and-tear line item by item, the state deadlines, how to write the itemized letter, and how to depreciate a damaged item so the charge holds up.

Almost every security deposit argument reduces to one question: is this the ordinary result of a person living in a home, or is it harm the tenant caused? Statutes rarely define the line precisely, which is why it helps to think about it as time versus behavior. Carpet that has thinned along the hallway after three years of walking is time. Carpet with a cigarette burn is behavior.

The practical test courts tend to apply: would this condition exist if a careful, ordinary tenant had lived here for the same length of time? If yes, it is wear and tear and you absorb it. If no, it is damage and you can charge for it.

One nuance worth internalizing: quantity changes the category. Four small nail holes are wear and tear. Sixty anchor holes across every wall from a gallery installation is damage. The same is true of scuffs, minor scratches, and grime — a normal amount is expected, an extreme amount is not.

The most common way a legitimate deduction gets reduced or thrown out is charging the tenant full replacement cost for something that was already partly used up. A tenant who destroys a five-year-old carpet does not owe you a new carpet — they owe you the value that was left in the old one.

The calculation is straightforward. Take the item's expected useful life, subtract the years already served, and charge that fraction of the replacement cost:

Typical useful-life assumptions run roughly 5–7 years for carpet, 3–5 years for interior paint, 10–15 years for appliances, and 20+ years for hard flooring — though your state or local housing authority may publish its own schedule that carries more weight. When an item is fully depreciated, the honest answer is that the deductible value is zero, even if the tenant destroyed it. You can still charge for labor and disposal.

Every state sets its own deadline for returning the deposit and sending the itemized statement, and the clock generally starts when the tenancy ends — not when the tenant asks. These are the deadlines in twenty commonly searched states:

If you keep any portion of the deposit, nearly every state requires a written itemized statement. This letter is the document that decides the case if the tenant disputes, so it is worth twenty careful minutes. Five things belong in it:

RE: Security deposit statement — [property address], Unit [#]
Tenancy ended: [move-out date]

Dear [Tenant name],

This is the itemized statement of your security deposit for the
property above, as required by [state] law.

Security deposit received on [date]:            $[amount]

Deductions:
1. Unpaid rent for [month]                      $[amount]
2. Replace [item] damaged by [cause]            $[amount]
   (Invoice from [vendor], dated [date], attached.
    Item was [X] years old with a [Y]-year useful life;
    charge reflects remaining value only.)
3. Cleaning beyond normal condition: [describe]  $[amount]
   (Invoice from [vendor], dated [date], attached.)
4. Replacement of [#] unreturned keys / rekeying $[amount]

Total deductions:                               $[amount]
Amount refunded to you:                         $[amount]

A check for $[amount] is enclosed with this letter.

Copies of all invoices and the move-in and move-out inspection
reports are attached. Photographs documenting each item listed
above are available on request.

If you have questions about any item, please contact me at
[phone] or [email].

Sincerely,
[Your name]
[Title, if applicable]

Send it by a method that produces proof of mailing. Certified mail with return receipt is the standard, and where your state and lease permit email, send it both ways. Keep a copy of the letter, the mailing receipt, and every attachment for at least the length of your state's statute of limitations on deposit claims.

Security deposit statutes are among the few landlord-tenant rules with real teeth, and the penalties are deliberately larger than the amount in dispute. Depending on the state and whether the withholding is found to be in bad faith, a landlord can be liable for two or three times the deposit, plus the tenant's attorney fees and court costs.

The important detail is that these penalties often attach to procedural failures, not just wrongful ones. In many states, sending a perfectly justified itemized statement four days past the deadline is treated the same as inventing the damage: you forfeit the deductions and return the full deposit. A $340 carpet charge can become a $2,000 judgment because a letter went out late.

That asymmetry is the whole reason to run a boring, repeatable process — inspection at move-in, inspection at move-out, photos of both, invoices for everything, itemized letter mailed well inside the deadline. Landlords who lose these cases rarely lose on the merits of the damage. They lose on documentation and dates.

The awkward truth about deposit disputes is that the outcome is largely decided long before move-out. By the time a tenant hands back the keys, either you have a dated record of what they owed and what condition the unit was in, or you are reconstructing it from memory and text messages.

The unpaid-rent portion of a deduction is the part landlords most often get wrong, because it depends on an accurate running ledger across the whole tenancy — not a guess about which months were short. If a tenant paid $900 against $1,200 in March and you never recorded the shortfall, that $300 is effectively gone.

For the full documentation system around this, see our guide to rental property record keeping, and our rent ledger guide covers exactly how to track balances so unpaid rent is never in dispute. If the tenancy ended badly, our playbook on handling delinquent rent walks through recovering what the deposit does not cover.

You can deduct for unpaid rent, real damage, restorative cleaning, unreturned keys, abandoned property, and unpaid utilities. You cannot deduct for the ordinary aging of your own asset. Depreciate anything with a useful life, itemize every charge with a receipt attached, and mail the statement well before your state's deadline.

Do that consistently and deposit disputes mostly stop happening — not because tenants become more agreeable, but because a clear, documented, itemized statement leaves very little to argue about. The landlords who end up in court over $400 in carpet are almost never the ones who took photos on move-in day.
