Seattle Security Deposit Law: Limits, Deductions, and Penalties

Under Seattle security deposit law, a landlord cannot collect more than one month’s rent in security deposit and non-refundable move-in fees combined, must let the tenant pay those costs in installments, and must return the deposit or send an itemized deductions statement within 30 days after the tenant moves out. These rules live in Seattle Municipal Code Chapter 7.24 and sit on top of the Washington State Residential Landlord-Tenant Act, so both city and state remedies are available when something goes wrong.

How Much a Landlord Can Charge

The security deposit plus any non-refundable move-in fees cannot exceed the first month’s rent.1Seattle.gov. Move-In Charges On a $2,000 unit, every dollar of deposit and non-refundable fees combined has to stay at or under $2,000.

Non-refundable move-in fees have their own ceiling inside that cap: they cannot exceed 10 percent of the first month’s rent.2Seattle City Council. Record No CB 118756 Screening costs generally count toward that 10 percent. So on the same $2,000 unit, non-refundable fees cap out at $200, leaving $1,800 as the most that can be collected as a refundable security deposit.

Pet damage deposits sit outside the main cap and have their own limit of 25 percent of the first month’s rent. That is $500 on a $2,000 unit, charged on top of the security deposit and move-in fees. The pet deposit rule applies only to actual pets. Under the federal Fair Housing Act, service animals and emotional support animals are not pets, so a landlord cannot require a pet deposit or pet rent for them. The tenant still owes for any damage the animal causes; what the landlord cannot do is collect the money upfront.

Paying Move-In Costs in Installments

Seattle gives tenants the right to spread security deposits, non-refundable move-in fees, and last month’s rent over several payments, with no interest, late fees, or added cost for choosing that option.2Seattle City Council. Record No CB 118756 The number of installments depends on the length of the lease:

  • Leases of six months or longer can be paid in six consecutive, equal monthly installments starting at the beginning of the tenancy.
  • Leases between 30 days and six months can be paid in up to four equal installments, at equal intervals across the lease term.
  • Month-to-month tenancies get two equal installments, with the first due at the start of the tenancy and the second due on the first day of the third week.

The landlord and tenant can agree in the rental agreement to a different schedule, so long as the total number of payments stays within what the code allows. One carve-out catches people off guard: the installment right does not apply when the deposit and non-refundable fees together come to less than 25 percent of the first month’s rent. On a $2,000 unit, installments are available only once those combined charges top $500.

Paperwork the Landlord Has to Provide

Collecting a security deposit requires a written rental agreement stating the deposit amount and the conditions under which any portion might be withheld. Without that written agreement, the deposit cannot legally be collected.

A move-in checklist is also non-negotiable. It records the condition of the unit before the tenant takes possession, covering floors, walls, windows, appliances, and any existing damage, and both parties must sign and date it.3Seattle.gov. Move In Checklist A landlord who skips this step, or produces a vague generic form, loses the ability to withhold any part of the deposit for damage at move-out.

The landlord must give the tenant a written receipt for the deposit and disclose where the money is being held. Washington law requires deposits to go into a trust account at a bank or financial institution, separate from the landlord’s own funds, and the written notice has to include the name and address of that institution.4Washington State Legislature. RCW 59.18.270 – Moneys Paid as Deposit or Security for Performance by Tenant The deposit stays in that account until the lease ends and the refund or deduction process plays out.

Getting Your Deposit Back After Move-Out

Once the tenancy ends and the tenant has moved out, the landlord has 30 days to either return the full deposit or send an itemized statement explaining any deductions along with whatever refund is owed.5Washington State Legislature. RCW 59.18.280 – Moneys Paid as Deposit or Security for Performance by Tenant The clock starts when the tenant vacates and the rental agreement terminates. The landlord does not need a forwarding address to begin counting days.

Any itemized statement has to be specific. Line items like “cleaning” or “repairs” without further detail do not meet the standard; invoices, receipts, or contractor estimates showing the actual costs should accompany the statement. The refund or statement must be delivered in person or mailed to the tenant’s last known address with first-class postage.5Washington State Legislature. RCW 59.18.280 – Moneys Paid as Deposit or Security for Performance by Tenant

Missing the 30-day deadline has teeth. A landlord who fails to provide the required statement, documentation, or refund in time becomes liable for the full deposit and loses the right to assert any claim for keeping the money. A court can award up to twice the deposit amount if it finds the failure was intentional, and the prevailing party in a deposit lawsuit recovers reasonable attorney fees.5Washington State Legislature. RCW 59.18.280 – Moneys Paid as Deposit or Security for Performance by Tenant

What Can and Cannot Be Deducted

Landlords can deduct for actual damage to the unit beyond normal wear and tear, and for unpaid rent or other charges allowed under the lease. They cannot deduct for the gradual deterioration that comes from simply living in a space over time. Washington’s Landlord-Tenant Act does not define “normal wear and tear” with a bright-line test, which is why the signed move-in checklist carries so much weight when a dispute surfaces.

As a rough guide, faded paint, minor scuffs on hardwood floors, worn carpet in high-traffic areas, and small nail holes from hanging pictures generally fall on the wear-and-tear side. Holes in drywall, stained or burned carpet, broken fixtures, and pet damage typically fall on the tenant’s side. The longer the tenancy, the more wear a landlord should expect. Carpet that looks tired after six years is not the same as carpet destroyed in six months.

Cleaning is a common point of overreach. A landlord can charge for cleaning only if the unit was left meaningfully dirtier than it was at move-in. Routine turnover cleaning is a cost of doing business, not a deposit deduction.

Penalties When Landlords Break the Rules

Seattle’s enforcement provisions go beyond the state-level return penalties. Under SMC 7.24.060, a landlord who charges more than the law allows or includes prohibited terms in a rental agreement is liable to the tenant for actual damages plus double the amount of any unlawfully forfeited deposit or imposed penalty, along with reasonable attorney fees.6Seattle Municipal Code. Seattle Municipal Code Title 7 – Consumer Protection, 7.24.060 A landlord who puts prohibited provisions in a new or renewed rental agreement also faces a flat $1,000 penalty per violation.

One procedural step matters before suing: the tenant must first request the deposit back from the landlord directly. This is a prerequisite under the code, and skipping it can undermine a later claim. A simple written request with a clear date is enough.

Seattle’s Department of Construction and Inspections can issue citations or notices of violation against landlords who fail to return deposits when required.7Seattle Department of Construction and Inspections. Deposit Returns So tenants have two avenues: a complaint to the city and a private lawsuit.

Taking a Deposit Dispute to Small Claims Court

Most deposit disputes land in small claims court, which is designed to work without a lawyer. Washington’s small claims courts handle cases up to $10,000, which covers most deposit disputes including double-damage claims on expensive units.8Washington State Courts. Small Claims Court Filing fees typically run between $30 and $75.

The landlord carries the burden of justifying any deductions. A landlord who shows up with a signed move-in checklist, dated photos, and repair invoices is in a far stronger position than one who says the place was trashed with nothing to back it up. On the tenant’s side, the strongest cases rest on photos taken at move-in and move-out, a copy of the signed checklist, and written correspondence requesting the deposit’s return.

If the dispute involves more than the deposit, such as habitability claims or other lease violations, the case can exceed small claims limits. In those situations, consulting an attorney makes sense, especially given that the prevailing party recovers attorney fees under RCW 59.18.280.
