Since its statehood in 1889, Washington state has developed some of the most detailed and rigorous maintenance obligations on residential landlords in the nation. Under RCW 59.18.060, the landlord's duty to maintain the property is both comprehensive and non-waivable—meaning the tenant cannot be forced to accept a substandard unit even if they sign a lease agreeing to it.

1. The Landlord's Statutory Duties (RCW 59.18.060)

A landlord must, at all times during the tenancy:

• Building Codes: Maintain the premises to substantially comply with any applicable code, statute, ordinance, or regulation governing their maintenance or operation, which the legislative body enacting the applicable code, statute, ordinance or regulation could enforce as to the premises rented if such condition endangers or impairs the health or safety of the tenant.
• Structural Integrity: Maintain the structural components including, but not limited to, the roofs, floors, walls, chimneys, fireplaces, foundations, and all other structural components, in reasonably good repair so as to be usable.
• Weatherproofing: Maintain the dwelling unit in reasonably weathertight condition.
• Plumbing: Maintain all electrical, plumbing, heating, and other facilities and appliances supplied by him or her in reasonably good working order.
• Hot and Cold Water: Provide facilities adequate to supply heat and water and hot water as reasonably required by the tenant.
• Heating: Provide facilities adequate to supply heat as reasonably required by the tenant.
• Electricity: Maintain the electrical system, including wiring and switches, in safe working order.
• Smoke Detectors: Provide a written notice to all tenants disclosing fire safety and protection information, including that the dwelling unit is equipped with a smoke detection device as required in RCW 43.44.110. The notice shall inform the tenant of the tenant's responsibility to maintain the smoke detection device in proper operating condition and of penalties for failure to comply with the provisions of RCW 43.44.110(3).
• Pests: Provide a reasonable program for the control of infestation by insects, rodents, and other pests at the initiation of the tenancy and, except in the case of a single-family residence, control infestation during tenancy except where such infestation is caused by the tenant.
• Common Areas: Keep any shared or common areas reasonably clean, sanitary, and safe from defects increasing the hazards of fire or accident. Except in the case of a single-family residence, provide and maintain appropriate receptacles in common areas for the removal of ashes, rubbish, and garbage, incidental to the occupancy and arrange for the reasonable and regular removal of such waste.
• Locks: Provide reasonably adequate locks and furnish keys to the tenant.

2. The Tenant's Duties (RCW 59.18.130)

Tenants also bear reciprocal maintenance responsibilities:

• Keep that part of the premises which he or she occupies and uses as clean and sanitary as the conditions of the premises permit.
• Properly dispose from his or her dwelling unit all rubbish, garbage, and other organic or flammable waste, in a clean and sanitary manner at reasonable and regular intervals, and assume all costs of extermination and fumigation for infestation caused by the tenant.
• Properly use and operate all electrical, gas, heating, plumbing and other fixtures and appliances supplied by the landlord.
• Not intentionally or negligently destroy, deface, damage, impair, or remove any part of the structure or dwelling, with the appurtenances thereto, including the facilities, equipment, furniture, furnishings, and appliances, or permit any member of his or her family, invitee, licensee, or any person acting under his or her control to do so.
• Not permit a nuisance or common waste.
• Maintain the smoke detection device in accordance with the manufacturer's recommendations, including the replacement of batteries where required for the proper operation of the smoke detection device, as required in RCW 43.44.110(3).

3. The Tenant's Powerful Repair Remedies

If a landlord fails to maintain the property as required, Washington tenants hold powerful legal remedies:

The "Repair and Deduct" Remedy

If the landlord fails to make necessary repairs after receiving written notice, the tenant may contract for the repair themselves and deduct the cost from future rent payments (under RCW 59.18.100). Specific procedural requirements apply, and the repair must relate to a condition specified in RCW 59.18.060.

Rent Escrow / Rent Withholding

In some circumstances, under RCW 59.18.115, tenants can deposit their rent into a court escrow account rather than paying the landlord, pending the completion of critical repairs.

Lease Termination

If the defects are severe enough to render the property uninhabitable (or the landlord's failure to repair substantially reduces the tenant's use of the premises), the tenant can terminate the lease entirely upon written notice.
