Security Deposit Deductions: What's Legal and What's Not (2026)

Security deposit disputes are among the most common landlord-tenant conflicts, and they are decided by three questions: was this deduction in a category the law allows, can you prove the condition and the cost, and did you send the itemized statement and the balance before your state's deadline? Miss any one and a substantively fair deduction can still be lost — in many states, with a penalty on top. This page works through each question, with the wear-and-tear line, the depreciation math, a worked example, and a checklist.

The short version: There is no general federal security deposit deduction statute. Deductions are governed by state law: your state's rules control the categories, deadline, itemization format, and penalty. Across most states the allowed categories converge: unpaid rent, damage beyond ordinary wear and tear, cleaning to restore the unit to its move-in cleanliness, lease-authorized charges, and unpaid utilities or fees the tenant owed. Never a valid category: ordinary wear, pre-existing damage, or an upgrade billed to the departing tenant. And when an item is damaged, you may charge only your actual loss — for an item partway through its useful life, the remaining value, not the price of a new one.

The five deduction categories

State statutes phrase the list differently, but the categories that recur across most states are these five. A deduction that does not fit one of them needs a specific statute or lease provision behind it — and even a lease provision fails if state law does not allow the parties to contract around the deposit rules.

1. Unpaid rent. Rent still owed at move-out is the least disputed deduction: the final month's shortfall, rent for a holdover period, or rent through the end of the lease term where the tenant broke the lease and the state allows the claim, usually subject to the landlord's duty to mitigate by re-renting. Keep the rent ledger as the proof; the deduction is only as strong as the ledger's accuracy.

2. Damage beyond ordinary wear and tear. Repair of damage the tenant or the tenant's guests caused — not deterioration from ordinary living. Section 3 below is devoted to this line, because it is where most disputes live.

3. Cleaning to restore, not to improve. Cleaning necessary to return the unit to the cleanliness it had at move-in. California's official courts guide states this standard plainly: cleaning on move-out is deductible only to make the unit as clean as it was when the tenant first moved in. Grease, filth, pet odor, and trash left behind qualify; a professional deep-clean you would commission between any two tenants, regardless of condition, is a turnover cost, not a deduction.

4. Lease-authorized charges. Charges the lease itself lawfully imposes and state law permits to be taken from the deposit: a lawful late fee still unpaid, rekeying where the tenant failed to return keys and the lease so provides, or restoring an alteration made without permission. Two cautions: the clause must actually exist and be enforceable in your state, and some states limit deposit use to a closed statutory list a lease clause cannot expand.

5. Unpaid utilities and fees the tenant owed. Final water, trash, or other utility amounts the lease made the tenant's responsibility and that remain unpaid, supported by the final bill. If the account was in the tenant's own name, the debt is usually between the tenant and the utility — deduct only amounts you actually paid or remain legally liable for.

Anything else — an "administrative fee," a blanket "redecorating charge," a fixed deduction applied to every move-out regardless of condition — is the kind of line item that gets a whole statement rejected. Charge for conditions, not for the fact of a move-out.

Wear and tear vs. damage: the line that decides most disputes

Ordinary wear and tear is the deterioration that happens from living in a home normally, over time, despite reasonable care. Damage is harm from an accident, misuse, neglect, or an unauthorized change. Washington's statute, RCW 59.18.280, states the floor expressly: a landlord may not withhold for wear resulting from ordinary use of the premises. Most states reach the same result by statute or case law even when the wording differs.

Two variables move the line. Time: the longer the tenancy, the more deterioration is ordinary — paint and carpet that look tired after five years are worn, not damaged. Cause: ask what a careful tenant living there for the same period would have produced. If the answer is "roughly this," it is wear.

The table states the usual outcomes, not a guarantee for any single case: condition at move-in, length of tenancy, and your state's wording all matter. Note the pattern in the right-hand column — each item involves a specific act or omission by this tenant, not the passage of time.

A useful test before you list any item: write the sentence "The tenant caused this by ___" and fill in the blank with a specific act or omission. If the only honest completion is "living here for three years," it is wear and tear.

The useful-life rule: you can charge only the value that was lost

Replacing a damaged item does not entitle you to its full price. An item that was already most of the way through its useful life had only a fraction of its value left; the tenant's damage destroyed that fraction, and that fraction is the loss. Charging full replacement cost for an old item gives the landlord a betterment — a new item, on the tenant, resetting a clock the tenant never owed — and courts and state guidance routinely reject it.

The method is simple proration, applied by courts and mediators generally:

• Step 1 — Replacement cost. What a like-kind, like-quality replacement costs. Not an upgrade: vinyl damaged, vinyl priced, even if you choose to install tile.
• Step 2 — Useful life. The item's expected service life in a rental, from a defensible written source applied consistently. A life-expectancy chart reproduced from U.S. Department of Housing and Urban Development housing guidance lists, for family units, plush carpeting at 5 years, flat interior paint at 3 years, enamel paint at 5 years, ranges at 20 years, refrigerators and hot water heaters at 10 years, and window shades and blinds at 3 years. Frame those figures for what they are — widely used guidance from HUD-assisted housing practice, not a universal legal mandate your state has adopted. A court will usually accept any reasonable, consistently applied schedule, and reject one invented for a single dispute.
• Step 3 — Age and remaining life. Remaining life = useful life minus age at tenancy end. If age meets or exceeds useful life, remaining value is zero, however the item died.
• Step 4 — Charge. Charge = replacement cost × (remaining life ÷ useful life).

If only one room's carpet is ruined, prorate that room's cost, not the whole unit's. And document the age claim — an install invoice or dated photo turns "the carpet was old" from an argument into a fact. The worked example below uses this math inside a full statement.

Cleaning charges, done lawfully

Cleaning is the deduction tenants challenge most and landlords document least. Keep it inside three limits:

• Necessity. The work must restore the unit to its documented move-in cleanliness. Photograph both states. A unit left broom-clean by the tenant does not support a $400 cleaning line because your standard turnover includes one.
• Actual scope. Itemize by task — kitchen degreasing, bathroom sanitizing, interior windows, trash removal — with time or invoice per task, not a single unexplained lump sum.
• Reasonable rate, including your own labor where allowed. Many states allow a landlord who cleans personally to charge a reasonable hourly rate; California's courts guide requires a landlord or employee who did the work to include a description of the work, the time spent, and the hourly rate, and states that any rates must be reasonable. Charge the local market rate for cleaning labor, log the hours contemporaneously, and never bill your own time at a skilled-trade rate for unskilled work.

Unpaid rent, last month's rent, and abandoned property

Unpaid rent is a deposit item; last month's rent is a separate thing. If the tenant prepaid last month's rent at move-in, that money was rent, held for one purpose: it pays the final month. It is not a second deposit you may re-characterize at move-out to cover damage, and in states that regulate deposits strictly, treating prepaid rent as a deposit can change the cap and accounting that apply. Conversely, a tenant may not unilaterally declare "use my deposit for the last month" — the deposit secures performance until the tenancy ends and condition is known, and most leases and many statutes say so. If the tenant skips the last month anyway, the unpaid rent becomes a deduction at move-out, documented by the ledger — the landlord applies the deposit then, on the statement, in the open.

Early termination. Where a tenant breaks the lease, amounts claimed for future rent usually depend on state mitigation rules and how quickly the unit re-rents. Keep the listing and showing records that prove mitigation.

Abandoned property is a separate procedure — do not fold it into the deposit statement. Property left behind is governed by its own state rules on notice, storage, and disposal, which vary widely. Storage or disposal costs are deductible only where your state allows them and the lease supports the charge; the property itself is not a windfall and not a bargaining chip for the deposit. Check your state page from the Security Deposit Laws by State hub before you throw anything away.

What cannot be deducted

• Pre-existing damage — anything present at move-in, whether or not the tenant noted it. This is why the move-in report protects the landlord as much as the tenant: an undocumented pre-existing flaw will be resolved against the party who was supposed to document it.
• Ordinary wear and tear — see the table above.
• Routine turnover costs — the repaint, carpet clean, lock change, and minor touch-up you would perform between any tenants as a cost of doing business, where the outgoing tenant left the unit in the condition ordinary use produces.
• Upgrades and betterment — the difference between the like-kind repair and the nicer replacement you chose; and, per the useful-life rule, the consumed portion of an old item's life.
• Damage from your own deferred maintenance — flooring ruined by a leak from aging plumbing you were responsible for, or mold from a ventilation defect, is a maintenance failure, not tenant damage, even when it is discovered at move-out.
• Amounts you cannot tie to a cost — round-number "fees" with no invoice, time log, or lease provision behind them.

The documentation chain that wins disputes

In most states the landlord carries the burden of proof on a deposit deduction: you withheld the tenant's money, so you prove the condition, the cause, and the cost. Build the chain before you need it:

1. Move-in condition report. Room by room, item by item, signed and dated by the tenant, noting existing flaws expressly. Some states require this checklist by statute and limit deductions when it was never done.

2. Move-in photos and video. Timestamped, every room, plus close-ups of floors, appliances, and any existing damage. California now builds photographic documentation into its deposit rules — a sign of where state law generally is heading.

3. During-tenancy records. Work orders, leak reports, and correspondence. A tenant who reported a leak promptly has a defense to the resulting damage; one who never reported it does not.

4. Move-out inspection. Promptly after move-out, before cleaners or workers enter, using the same checklist as move-in, with the tenant invited or present where your state gives that right.

5. Move-out photos. Same angles as move-in. Before-and-after pairs are the single most persuasive exhibit in a deposit dispute.

6. Cost proof. Paid invoices and receipts for work done by others; time log, description, and reasonable hourly rate for your own labor.

7. The itemized statement. Every deduction described, categorized, and priced, with depreciation math shown where you prorated — as in the example below.

8. Proof of sending. The statement and balance sent to the tenant's forwarding address (or last known address where the state allows) by a method that proves the mailing date.

Keep the whole file for at least the period your state allows a tenant to sue over a deposit — in practice, several years. Storage is cheap; reconstruction is impossible.

Itemization, estimates, and the deadline that can forfeit everything

Almost every state requires a written itemized statement with the balance, within a deadline that runs from move-out, lease termination, or delivery of the forwarding address — the trigger and the length are state law. Deadlines across the states run roughly from two weeks to about two months. Find yours before move-out day with the Security Deposit Deadline Finder, and confirm the trigger on your state page.

Receipts vs. estimates. Where work is complete, attach actual invoices or receipts; states commonly require them above a threshold or on request. California's rule, from its courts guide, is a workable model of the pattern: for deductions over $125, copies of invoices or receipts must accompany the statement; if the work cannot reasonably be finished within the 21-day return period, the landlord may send a good-faith estimate by the deadline and must then send the final documentation within 14 days after the work is completed. An estimate is a bridge with a follow-up duty, not a final number — states differ on whether estimates are allowed at all and on the true-up deadline, so check yours.

Forfeiture and penalty risk. This is the part landlords underestimate. In many states, missing the deadline or the itemization requirement does more than delay things: the landlord can forfeit the right to withhold any amount, owe the full deposit back regardless of real damage, and face statutory damages on top — commonly expressed as a multiple of the amount wrongfully withheld or of the deposit, plus, in some states, the tenant's attorney's fees. California, for example, exposes a landlord who retains a deposit in bad faith to damages of up to twice the deposit in addition to the deposit itself, per its courts guide. Other states set their own multipliers and triggers, and some condition penalties on bad faith while others attach them to the missed deadline alone. The exact exposure for your property is on its state page in the Security Deposit Laws by State hub — read it before you are late, not after.

Deadlines are the part landlords actually miss, and the miss is administrative, not substantive. The Security Deposit Disposition & Deadline Tracker 2026 ($14.95) tracks every deduction and unit against your state's deadline so nothing slips through the cracks.

A worked example, with dates and depreciation math

A tenant's lease ends and the tenant moves out on Wednesday, September 30, 2026. Rent was $1,800 a month and the deposit held is $1,800. The move-in report and photos from the start of the tenancy are on file. The landlord inspects on Thursday, October 1, 2026, before any cleaning, and photographs every room against the move-in set.

The itemized statement finds:

• Unpaid rent — $300. The tenant paid $1,500 of September's $1,800 rent. Ledger attached. Deduction: $300.
• Carpet damage beyond wear — $225, not $900. Pet urine has soaked the bedroom carpet and padding beyond cleaning. Like-kind replacement for that room costs $900. The carpet was installed 6 years before move-out and is assigned an 8-year useful life on the landlord's written schedule, so remaining life is 8 − 6 = 2 years. Charge: $900 × 2/8 = $900 × 0.25 = $225. The remaining $675 of replacement cost is the consumed life of the old carpet and is the landlord's, not the tenant's.
• Wall damage — $180. One large hole from a wall anchor torn out, repaired and the affected wall repainted to match, per the contractor's invoice. The invoice is attached.
• Cleaning to restore — $210. The kitchen and bathroom were left well below documented move-in cleanliness. A cleaning service invoiced 6 hours at $35 an hour: 6 × $35 = $210. Invoice attached.
• Unpaid utility — $95. The final trash bill the lease made the tenant's responsibility, paid by the landlord after move-out. Bill attached.
• Not charged — $0. Faded paint in the living room after a multi-year tenancy, a few small nail holes, and traffic-lane carpet wear in the hallway are ordinary wear and tear. A full-unit repaint was quoted at $600; none of it is deducted.

Now the arithmetic, shown as the statement shows it:

• Total deductions: $300 + $225 = $525; $525 + $180 = $705; $705 + $210 = $915; $915 + $95 = $1,010.
• Balance due to the tenant: $1,800 − $1,010 = $790.

The statement and the $790 balance are mailed on Wednesday, October 14, 2026 — 14 days after move-out. Why that date matters: deadlines are state-specific, but to see the test, suppose this property sits in a state with a 30-day deadline counted from move-out. The deadline would be Friday, October 30, 2026, and the October 14 mailing is comfortably inside it. If your state allows only 14 or 21 days, the same statement sent on the same day could already be late — which is the entire point: work out your deadline from the Security Deposit Deadline Finder and your state page on the day the tenant gives notice, not the day you sit down to do the math.

The compliance checklist

1. Before move-in, complete a signed, dated condition report with the tenant and take timestamped photos of every room.

2. Keep a written useful-life schedule for paint, carpet, flooring, blinds, and appliances, and apply the same schedule to every tenancy.

3. On notice to vacate, look up your state's return deadline, its trigger, and its itemization rules, and calendar the date.

4. Inspect promptly after move-out — before cleaning or repairs — using the move-in checklist, and photograph the same angles.

5. Separate every observed item into damage, wear, pre-existing, or turnover cost. Deduct only the damage column.

6. For each damage item, record the specific act or omission that caused it and the move-in evidence that it was not already there.

7. Price repairs at like-kind cost; prorate any replacement by remaining useful life and show the math on the statement.

8. Itemize cleaning by task, backed by an invoice or by a time log with a reasonable hourly rate for your own labor.

9. Attach receipts or invoices for completed work; if your state allows a good-faith estimate for unfinished work, calendar the follow-up final statement it requires.

10. Send the itemized statement and the balance, with proof of mailing, before the deadline — and file the complete record, ledger included, for several years.

The bottom line

A lawful deduction is a documented one: an allowed category, a condition you can prove against the move-in record, a cost you can show, depreciation taken where life was already consumed, and a statement sent before a deadline you looked up in advance. Landlords rarely lose because the damage was imaginary. They lose because the file was. Build the file at move-in and the move-out math becomes the easy part.

Frequently Asked Questions

Can I deduct unpaid rent from a security deposit?

Yes, in most states unpaid rent still owed at move-out is a standard deposit deduction, supported by the rent ledger. That includes a shortfall in the final month and, where the tenant broke the lease, amounts state law allows after your duty to mitigate. Prepaid last month's rent is different money: it pays the final month and is not a second deposit for damage.

Can a tenant tell me to use the deposit as the last month's rent?

Generally, no. The deposit secures the tenant's obligations until the tenancy has ended and the unit's condition is known, and most leases and many state statutes prohibit applying it to rent during the tenancy. If the tenant withholds the last month anyway, the unpaid rent becomes a documented deduction on the move-out statement.

How do I charge for damaged carpet without charging full replacement cost?

Prorate by remaining useful life. Divide a like-kind replacement cost by the item's useful life, and charge only the years of life remaining when the tenancy ended: a $900 carpet replacement with 2 of 8 years of life left supports a $225 charge, not $900. If the carpet was already at or past the end of its useful life, its remaining value — and the lawful charge — is zero.

Are small nail holes and faded paint deductible?

Ordinarily, no. A few small nail holes from hanging pictures, fading, and minor scuffs are textbook ordinary wear and tear, particularly after a longer tenancy. Large holes, torn-out anchors, unauthorized paint colors, and smoke staining are damage. The length of the tenancy matters: the longer the stay, the more deterioration the law treats as ordinary.

Can I charge for my own cleaning and repair time?

In many states, yes, where the work itself is deductible — at a reasonable hourly rate, documented with a description of the work and the time it took. California's courts guide requires exactly that documentation for landlord-performed work and requires the rate to be reasonable. Bill at the local rate for the kind of labor performed, log hours as you work, and check your state page for any contrary rule.

What happens if I miss my state's itemization or return deadline?

In many states the consequences are severe: forfeiture of the right to withhold any of the deposit, a duty to return it in full despite real damage, and statutory damages that can reach a multiple of the deposit or of the amount wrongfully withheld, sometimes plus the tenant's attorney's fees. The exact trigger and multiplier are state law — look yours up before move-out, because the penalty usually cannot be cured after the deadline passes.

Can I use an estimate if the repairs are not finished by the deadline?

It depends on the state. Some states allow a good-faith estimate by the deadline with a duty to send final receipts and refund any excess by a second deadline; California, for example, allows an estimate when work cannot reasonably be finished in its 21-day period and requires the final documentation within 14 days after completion. Other states are stricter. Never treat an estimate as final without confirming your state allows it and calendaring the true-up.

What should I do with property a tenant leaves behind?

Follow your state's abandoned-property procedure — notice, storage, and disposal rules vary widely — and do not treat the property as yours or as leverage over the deposit. Storage or disposal costs are deductible only where state law and the lease allow them. Document what was left with photos and an inventory on move-out day.
