Security Deposit Basics: What Every Renter Needs to Know

What is a security deposit?

A security deposit is money you give to your landlord at the start of a tenancy to cover potential damage to the property, unpaid rent, or other costs you might leave behind. The key word is deposit — it is your money. The landlord holds it in trust and must return it (minus any legitimate deductions) when you move out.

That's the theory. In practice, security deposits are one of the most common sources of disputes between landlords and tenants — usually because one or both sides don't fully understand what the law allows.

How much can a landlord charge?

It depends on your state. About half the states cap deposits at one or two months' rent. Some states (Texas, Florida, Georgia, Illinois, and many others) have no statutory cap at all — meaning landlords can charge whatever they want, although market norms usually keep deposits to one or two months.

A few examples:

• California: Maximum 1 month's rent (changed July 2024).
• New York: Maximum 1 month's rent (statewide since 2019).
• Massachusetts: Maximum 1 month, with strict additional rules.
• Nevada: Maximum 3 months — including any non-refundable fees.
• Texas, Florida, Illinois: No cap.

What can a landlord legally deduct?

Generally, landlords can deduct from your deposit for:

• Unpaid rent. If you owe back rent or broke the lease early.
• Damage beyond normal wear and tear. Holes in walls, broken windows, damaged appliances, large stains, undisclosed pet damage.
• Cleaning costs — but only if the unit was left noticeably dirtier than at move-in. Routine cleaning is the landlord's expense.
• Other lease-specified charges — late fees that have accrued, utility charges if the lease made you responsible.

What is “normal wear and tear”?

This is the single most-disputed concept in security deposit law. Normal wear and tear is the gradual deterioration from ordinary use — and landlords cannot charge you for it.

Normal wear and tear (you should not be charged):

• Faded paint or wallpaper from sunlight
• Worn carpet from regular foot traffic
• Small nail holes from hanging pictures
• Loose hinges or doorknobs from use
• Minor scuffs on walls from furniture
• Dirty grout in old bathrooms

Damage (landlord can charge):

• Large holes in walls
• Carpet stains, burns, or rips
• Broken tiles, fixtures, or appliances
• Pet urine damage
• Crayon, marker, or paint on walls
• Mold from preventable causes (e.g., never opening a bathroom window)

When does the landlord have to return the deposit?

Every state sets a deadline. The shortest is 14 days. The longest is 60 days. Most fall in the 21–45 day range. The clock generally starts on the day you move out — or, in some states, the day you provide a forwarding address in writing.

If your landlord misses the deadline, most states impose a penalty — typically 2x or 3x the wrongfully withheld amount, plus attorney's fees. To find your state's specific deadline and penalty, use our Security Deposit Return Calculator.

Five things to do at move-in to protect yourself

1. Document everything with photos and video. Walk through every room. Pay extra attention to carpet, walls, appliance interiors, blinds, screens.
2. Fill out a move-in checklist. If your landlord doesn't provide one, make your own and ask them to sign it.
3. Get a written receipt for the deposit. Some states require landlords to disclose where the deposit is held.
4. Read the lease. Look for: deposit return timeline, permitted deductions, cleaning requirements, and any non-refundable fees being labeled as “deposit.”
5. Save everything. Lease, receipts, photos, every email or text with the landlord.

Five things to do at move-out

1. Give proper written notice. Most leases require 30 days, in writing. Send certified mail or get a signed receipt.
2. Clean thoroughly. Compare to your move-in photos — return the unit to that condition or better.
3. Take move-out photos and video. Date stamps matter.
4. Request a walk-through inspection. Many states give you the right to be present when the landlord inspects.
5. Provide a forwarding address in writing. In many states the landlord's deadline doesn't start until they have it.

What if the landlord won't return your deposit?

You have options — and they're more powerful than most renters realize. See our companion guide: What to Do If Your Landlord Won't Return Your Security Deposit.
