Quick AnswerWashington landlords must pair a written lease with several disclosures under the Residential Landlord-Tenant Act (RCW 59.18). No deposit may be collected without a signed move-in condition checklist (RCW 59.18.260), the deposit must be held in a trust account with the bank disclosed (RCW 59.18.270), and the landlord must give the tenant the state mold information and a fire-safety / smoke-detector notice (RCW 59.18.060). Pre-1978 housing also requires the federal lead-based paint disclosure.
Washington ties several disclosures directly to the ability to collect a deposit, so getting them right matters at move-in. This checklist covers each disclosure and the statute behind it.

The move-in checklist and deposit bank disclosure

Move-in checklist (RCW 59.18.260): a landlord cannot collect a security deposit unless the rental agreement is in writing and is accompanied by a written checklist describing the condition and cleanliness of the unit, signed by both parties. Collecting a deposit without it makes the landlord liable to the tenant for the deposit amount plus costs and fees.

Deposit bank disclosure (RCW 59.18.270): the deposit must be held in a trust account with a Washington bank or escrow agent, and the landlord must give a written receipt and disclose the name and address of the depository.

Mold and fire-safety disclosures (RCW 59.18.060)

Mold information: the landlord must provide the Washington Department of Health's information on indoor mold and its health effects to new tenants at the start of the tenancy.

Fire safety / smoke detectors: the landlord must give written notice that the unit has a smoke-detection device, the tenant's duty to maintain it, and the penalties for noncompliance, signed by both parties; multifamily notices must also address whether detectors are hard-wired, and whether the building has sprinklers, a fire alarm, a smoking policy, and an evacuation plan.

Federal lead-based paint disclosure

For any dwelling built before 1978, federal law requires the landlord to provide the signed lead-warning disclosure, any known records, and the EPA pamphlet Protect Your Family From Lead in Your Home.

Local disclosures to check

Washington cities add their own requirements. Seattle, for example, requires landlords to distribute a summary of the city's landlord-tenant regulations, and several cities cap move-in costs and late fees. Confirm the local requirements for the property's city before finalizing the lease.

What happens if a Washington landlord skips a required disclosure?

Consequences vary:

  • No move-in checklist: the landlord cannot lawfully keep the deposit and may owe the tenant the deposit amount plus costs (RCW 59.18.260).
  • No bank disclosure: undercuts the landlord's right to retain the deposit (RCW 59.18.270).
  • Federal lead-paint violation: carries civil and, in egregious cases, criminal penalties plus tenant damages.
