Washington Security Deposit Rules: Caps, Lawful Deductions & Penalties (2026)

How much a landlord can charge, and which deductions are actually legal

At a glance

Who this covers — and who it does not

This page covers how much a landlord may charge in Washington, and which deductions from a residential deposit are lawful. It assumes the tenancy has ended and the question is what may be withheld.

It does not cover:

How much the landlord may charge in the first place

No statewide cap. Washington imposes no statutory limit on the amount of a security deposit under RCW 59.18 (unlike states such as California or Georgia). RCW 59.18.610 addresses installment payment of deposits, not a cap.

Caps frequently carry exceptions — smaller landlords, furnished units, or pets are treated differently in most states. Read the provision itself rather than relying on the headline figure.

Which deductions the statute permits

Claimed deductionPermitted in Washington
Damage beyond ordinary wear and tear (substantiated by estimates/invoices/receipts)Permitted, if substantiated
Unpaid rent or other charges owing (per RCW 59.18.280(4), which exempts these from the checklist/documentation requirements)Permitted, if substantiated
Carpet cleaning, but only where the landlord documents wear beyond ordinary usePermitted, if substantiated

Which deductions the statute does not permit

Claimed deductionPermitted in Washington
Wear resulting from ordinary use of the premisesNot permitted
Carpet cleaning without documented wear beyond ordinary useNot permitted
Repair/replacement of fixtures, equipment, appliances, or furnishings not reasonably documented in the move-in checklistNot permitted
Any deduction in excess of the cost of repair/replacement of the damaged portionNot permitted
Any retention without a full and specific statement + documentation within 30 daysNot permitted

Whether a specific charge is lawful depends on the facts — how old the damage is, whether the lease addressed it, and whether the landlord can document the cost. A charge being in the "permitted" column does not make it automatically collectable.

Who has to prove what

The landlord must give a full and specific statement with supporting documentation (estimates, invoices, receipts) to justify any retention. Failure to do so makes the landlord liable for the full deposit and bars the landlord from asserting any claim or defense for retaining the deposit, unless the landlord shows circumstances beyond its control prevented timely compliance.

In Washington the burden sits with the landlord. This matters strategically: if the burden is theirs, your task is to request the documentation rather than to prove the deduction wrong. RCW 59.18.280(1)(b), (2) ↗

Tools that exist in Washington

No statewide deposit cap

Washington is one of the states with no statutory limit on security deposits. A landlord may demand a large deposit, but this cuts both ways: the full-deposit liability and the checklist requirement apply regardless of size.

RCW 59.18 (whole chapter) ↗

The move-in checklist is a condition of collection

A landlord may not collect a deposit unless the agreement is in writing AND a signed written checklist describing the condition of the premises is provided at move-in. Collecting without the checklist makes the landlord liable for the full deposit, independently of the return deadline.

RCW 59.18.260(2), (5) ↗

Automatic full-deposit liability, then up to 2x

On any failure to return the deposit with a proper statement and documentation within 30 days, the landlord is automatically liable for the full deposit. Separately, the court may award up to two times the deposit for an intentional refusal. The base recovery is the full deposit; the 2x is a discretionary ceiling.

RCW 59.18.280(2) ↗

Statute of limitations: 6 years on a written contract

A deposit claim under a written lease is an action on a written contract, subject to a 6-year limitations period under RCW 4.16.040(1).

Common landlord defences and how to answer them

““I kept the deposit for cleaning and damage.””

Washington requires a full and specific statement plus supporting documentation (estimates, invoices, or receipts) within 30 days of termination and vacation. A blanket figure is not a statement. Provide the specific basis and documentation, or return my deposit in full.

RCW 59.18.280(1)

““There was no written checklist, so I don't have to itemize.””

The opposite is true: without a signed written checklist at move-in, you were not entitled to collect the deposit at all, and you are liable for the full amount (RCW 59.18.260(5)).

RCW 59.18.260(2), (5)

““The carpet needed professional cleaning.””

Carpet cleaning may not be withheld unless you document wear beyond ordinary use (RCW 59.18.280(1)(c)(ii)). Ordinary wear from normal living is not chargeable.

Where sources disagree

Some widely circulated summaries of Washington deposit law state things the statute does not say. We list the disagreements rather than picking a side silently.

Penalty basis (full deposit vs wrongfully withheld)

SourceWhat it says
Some multi-state checklists2x the amount wrongfully withheld
RCW 59.18.280(2)Full amount of the deposit, plus up to 2x the deposit for intentional refusal

What we follow: Full deposit (automatic) + up to 2x the deposit (discretionary)

The statute is explicit: base liability is "the full amount of the deposit," and the 2x is "up to two times the amount of the deposit" — both keyed to the deposit, not a "wrongfully withheld" portion.

Deposit cap (none vs a cap)

SourceWhat it says
Some generic summaries1 month's rent cap
RCW 59.18 (whole chapter)No statutory cap

What we follow: No statewide cap

No provision of RCW 59.18 sets a deposit ceiling. RCW 59.18.610 concerns installment payment, not a cap.

Common questions

What can a landlord not deduct from my Washington deposit?

The statute does not permit deductions for: wear resulting from ordinary use of the premises; carpet cleaning without documented wear beyond ordinary use; repair/replacement of fixtures, equipment, appliances, or furnishings not reasonably documented in the move-in checklist; any deduction in excess of the cost of repair/replacement of the damaged portion; any retention without a full and specific statement + documentation within 30 days.

Who has to prove that a deduction was justified in Washington?

The landlord. The landlord must give a full and specific statement with supporting documentation (estimates, invoices, receipts) to justify any retention. Failure to do so makes the landlord liable for the full deposit and bars the landlord from asserting any claim or defense for retaining the deposit, unless the landlord shows circumstances beyond its control prevented timely compliance.

How much can a landlord charge as a deposit in Washington?

No statewide cap. Washington imposes no statutory limit on the amount of a security deposit under RCW 59.18 (unlike states such as California or Georgia). RCW 59.18.610 addresses installment payment of deposits, not a cap.

Is ordinary wear and tear deductible from my Washington deposit?

No. The statute excludes ordinary wear and tear.
