How much can you charge in Washington?

No statutory cap. Move-in fees/deposit installments have their own rules; checklist required to collect a deposit at all.

Returning the deposit: the 30 days deadline

After the tenancy ends, Washington gives you 30 days to return the deposit. Extended from 21 days by 2023 legislation; documentation required for damage deductions. Blowing the deadline is the single most common way landlords lose deposit disputes — courts read these statutes strictly, and in many states a late or missing itemization forfeits your right to keep anything.

What you can deduct

  • Unpaid rent and other amounts the lease authorizes
  • Damage beyond normal wear and tear — holes in walls, broken fixtures, pet damage
  • Never normal wear and tear — faded paint, carpet worn by ordinary use, minor scuffs

The dispute is almost never about the rule — it's about the evidence. Date-stamped move-in and move-out photos plus an itemized statement with receipts is what wins in small-claims court.

Interest and holding requirements

Washington has no general statewide requirement to pay interest on residential security deposits (local ordinances can differ — check your city). Some states in this position still regulate where deposits are held; see RCW 59.18.260–.285 for any account or disclosure rules that apply to you.

Frequently asked questions

How much can a landlord charge for a security deposit in Washington?

There is no statewide dollar cap — the lease sets the amount, though local ordinances may impose limits. See RCW 59.18.260–.285.

How long does a Washington landlord have to return a security deposit?

30 days after the tenancy ends, generally with an itemized statement of any deductions. Missing the deadline can forfeit your right to deduct — and in many states triggers statutory damages.

What can a landlord deduct from a deposit in Washington?

Typically unpaid rent, damage beyond normal wear and tear, and other charges the lease authorizes. Normal wear and tear — faded paint, worn carpet from ordinary use — is never deductible. Documentation (move-in/move-out photos and an itemized list) is what wins disputes.

Handling Washington deposits with LandlordPro

LandlordPro keeps a ledger of every deposit you hold — who paid it, which lease it secures, and what happened to it. When a tenancy ends, the settlement workflow records what you returned and what you kept (with reasons), generates a tenant-facing settlement statement, and books any kept portion into your income reports correctly. Combined with the Washington eviction guide and move-in/move-out inspections with photos, you'll have the paper trail that deposit statutes reward.
