Security deposit law is state law, and the details vary, but the architecture is the same nearly everywhere: the deposit is your money, held against specific costs, returnable on a deadline, with an itemized accounting when anything is kept.
Normal wear versus damage
The dividing principle is whether the condition results from ordinary living or from misuse. Time and use produce wear, and wear is the landlord's cost of doing business, priced into the rent.
- Wear, not deductible: faded or scuffed paint, carpet flattened along walking paths, small nail holes from pictures, loose door handles, worn enamel, sun-faded blinds.
- Damage, deductible: broken windows, large holes in walls, burns or pet stains in carpet, missing fixtures, unauthorized paint colors, appliance damage beyond age.
Cleaning sits in between. Most states allow deductions to return the unit to the cleanliness it had at move-in, and no further. A professional cleaning fee charged automatically, regardless of condition, is not allowed in many states.
Depreciation matters
Even for genuine damage, a landlord generally cannot charge you the price of new. Carpet has a useful life, commonly treated as five to ten years. If you ruin carpet that was already eight years old, the deductible amount is its remaining value, which may be close to nothing. The same logic applies to paint, which most landlords are expected to refresh every few years anyway. Deductions that quote full replacement cost for aged items are the most commonly overturned in disputes.
The deadline and the itemization
States set a return deadline, typically 14 to 45 days after you move out and return keys. If anything is withheld, you are owed a written itemized statement of the deductions, often with receipts or estimates required. Missing the deadline or skipping the itemization has teeth in many states: the landlord can forfeit the right to keep anything, and some states award you two or three times the wrongly withheld amount.
What happens when the building changes hands
Selling the property does not extinguish your deposit. In most states the obligation transfers to the new owner, who becomes responsible for returning it, and many states require the old owner either to transfer the funds and notify you or to return the deposit directly. If your building sells mid-tenancy, write to both parties confirming the deposit amount and asking who now holds it. That letter, sent at the time, prevents the "the previous owner had it" argument two years later.
Protecting the deposit, start to finish
- At move-in: complete the condition checklist if offered, photograph every room including inside appliances, and email the photos to the landlord so they are dated and acknowledged.
- During the tenancy: report maintenance problems in writing. A leak reported and ignored is the landlord's damage, not yours.
- At move-out: clean to move-in standard, photograph everything again, request a walkthrough (some states require offering one), return all keys, and give a forwarding address in writing, since the return deadline often runs from that.
How much a landlord can hold in the first place
Many states cap the deposit, commonly at one or two months' rent, sometimes with a higher limit for furnished units or pet deposits. Some states require deposits to be held in a separate account, occasionally an interest-bearing one with the interest owed to you, and a few require the landlord to tell you where it is held within a set period after move-in. Non-refundable fees are treated as deposits in some states regardless of the label, meaning a "non-refundable cleaning fee" may not be non-refundable at all.
If the deposit does not come back
Write a demand letter first: the amount, the legal deadline that has passed, and a date you expect payment by. Many disputes end there, because landlords know the penalty math. The next step is small claims court, which handles deposit cases constantly, requires no lawyer, and costs a modest filing fee that gets added to the judgment when you win. Your move-in photos, your written repair requests and the missing itemization are usually the whole case.
