What Are Security Deposits Usually Used For?

A security deposit is usually used for four things: rent the tenant did not pay, repairs for damage beyond normal wear and tear, cleaning needed to return the unit to the condition it was in at move-in, and other charges your lease and state law allow, such as unpaid utilities. It cannot cover ordinary wear and tear, damage that was there before the tenant moved in, or the routine work you do between every tenancy. When the damaged item was already old, California's Department of Real Estate (DRE) describes a common method that charges only for the useful life the item had left, not the full replacement price.

What can you deduct from a security deposit?

State statutes list the allowed uses, and the lists are similar. For deductions after move-out, follow the process of returning a security deposit. Massachusetts legal aid guidance also allows using the deposit for rent or tenant-caused damage during the tenancy if you and the tenant agree.

1. Unpaid rent. Rent the tenant still owes at move-out. Massachusetts excludes rent the tenant lawfully withheld because of bad conditions.
2. Damage beyond normal wear and tear. Repairs for damage caused by the tenant, a household member, or a guest. New York bars deductions for damage left by a prior tenant.
3. Cleaning. California allows cleaning only to bring the unit back to the level of cleanliness it had when the tenant moved in. A unit that was dirty at move-in can be returned equally dirty without a charge.
4. Other charges the law and lease allow. New York adds unpaid utilities the tenant owed directly to you and the cost of moving and storing belongings the tenant left behind. California allows restoring or replacing furniture and other personal property you supplied, if the lease says the deposit may be used that way. Texas allows any charge the tenant is legally liable for under the lease.

Two state limits apply across those categories:

• No "nonrefundable" deposit in California. A California lease cannot label any part of the security as nonrefundable.
• The tenant cannot spend the deposit as last month's rent in Texas. A Texas tenant who withholds the last month's rent because the deposit covers it can owe you three times the rent withheld plus attorney's fees.

Massachusetts allows only unpaid rent, an unpaid property tax increase the lease requires, certain unpaid water charges, and damage beyond reasonable wear and tear. Massachusetts legal aid guidance treats routine painting and cleaning, new locks and keys, and small carpentry repairs as reasonable wear and tear, so they cannot come out of the deposit.

What counts as normal wear and tear?

Texas defines normal wear and tear as deterioration that results from the intended use of the home. Deterioration from negligence, carelessness, accident, or abuse by the tenant, a household member, or a guest is damage. Washington bars withholding for "wear resulting from ordinary use of the premises." California also bars charging for the cumulative effect of wear across several tenancies.

The examples below come from the California DRE guide:

Washington adds a carpet rule: you cannot withhold for carpet cleaning unless you document wear to the carpet beyond ordinary use. California bars charging for professional cleaning, including carpet cleaning, unless it is reasonably necessary to return the unit to its move-in cleanliness.

The comparison only works if you recorded the starting condition. A dated checklist and photos, signed by the tenant, are your proof; see whether a move-in inspection is required. Washington goes further: you cannot collect a deposit at all without a written lease and a signed, dated move-in checklist.

How does an item's age limit what you can charge?

The DRE guide describes a common method that prorates the replacement cost, so a tenant who ruins an item pays for the life it had left, not for a new one.

Carpet example from the DRE guide. A tenant damages a carpet beyond repair. The carpet is 8 years old with a 10-year life expectancy, and a replacement of similar quality costs $1,000.

• Remaining life: 10 years - 8 years = 2 years.
• Share of life left: 2 / 10 = 20%.
• Deduction: 20% x $1,000 = $200.

A carpet past its expected life has no value left to charge for, and its wear counts as normal wear and tear even if some of it happened during this tenancy.

Paint. Repainting is chargeable only when the walls have damage beyond normal wear or soiling that cannot reasonably be cleaned. For that case, the DRE guide suggests an approach that assumes interior paint lasts two years:

Example: a tenant who stayed 18 months left walls marked with crayon that would not wash off, and repainting the room costs $450. Under this approach you could deduct one-third, or $150.

The DRE guide calls these suggestions consistent with the law, not rules in a statute, and some landlords assume a longer paint life. Courts judge whether a deduction was reasonable, and in California, New York, and Texas you carry the burden of proving it. A charge based on remaining life is easier to defend than a full replacement price for an old item.

What happens when the damage costs more than the deposit?

Deduct up to the full deposit, list every charge on the itemized statement, and pursue the rest separately. The DRE guide notes that a California landlord can seek damage or unpaid rent beyond the deposit in court, including as a counterclaim if the tenant sues over the deposit. Massachusetts legal aid guidance says a landlord must sue separately for damage if the tenant sues for the deposit and the landlord failed to provide a complete itemized damages list within 30 days after occupancy ended. The deposit limits what you can keep on your own, not the total the tenant may owe.

How you price, document, and defend the charges is covered in what to pay attention to when returning a security deposit. State-specific deduction rules are in the California security deposit laws for landlords and the Texas security deposit laws for landlords, and the broader move-in checklist is in how to help your tenant get set up.
