Essential Building Codes Washington Renters Need to Know

Understanding your rights as a renter in Washington means knowing not just what’s in your lease, but also how state and local building codes protect your home’s safety and habitability. Building codes set the minimum safety and health standards for things like heating, plumbing, electricity, and structural stability. In Washington, both state and local laws ensure that rental homes remain safe and livable—helping you address concerns and repairs with clarity and confidence.

Washington's Building Code Basics for Renters

Most rental properties in Washington must follow the Washington State Building Code and local city or county regulations. These rules cover essentials like:

• Safe water supply and plumbing
• Working heating and electrical systems
• Proper ventilation and indoor air quality
• Weatherproofing and protection from the elements
• Smoke detectors and carbon monoxide alarms

The state’s Residential Landlord-Tenant Act (RLTA) requires landlords to keep rentals ‘fit for human habitation’¹.

Key Habitability Requirements

• Heating: Every rental must have safe, working heating capable of maintaining at least 68°F in living spaces during winter.
• Hot and Cold Water: Safe water and functional plumbing are required.
• Smoke & CO Alarms: Operational smoke alarms are required in all bedrooms and on every floor. Carbon monoxide alarms are required if the unit uses gas or has an attached garage.
• Locks & Security: Doors and windows must have functional locks.
• Structural Safety: The property can’t have leaks, holes, or unsafe floors, stairs, or railings.

Specific local rules may add extra protections. For example, Seattle and Tacoma have their own housing codes.

What If a Building Code Is Violated?

When repairs aren’t made and building code violations put your health or safety at risk, the law gives you ways to act.

• Start by asking your landlord in writing for repairs. Be clear and keep copies.
• If not fixed promptly, you can report violations to your local code enforcement office.

Relevant Official Forms

• Repair Request Letter (No Official Number): Washington tenants should notify landlords in writing about needed repairs. Use this before filing a complaint. See a sample template from the Washington Attorney General’s guide.
  • When to use: As soon as you notice safety, health, or major repair issues in your rental home.
• Property Code Complaint Form (No Official Number): Most cities and counties have online or printable building code complaint forms. Seattle renters use the Seattle SDCI Complaint Portal.
  • When to use: If your landlord does not address urgent repairs or building violations after proper notice.

Who Handles Housing and Tenant Complaints?

The Washington State Attorney General’s Office provides tenant rights education and complaint guidance but does not enforce repairs. Code enforcement and habitability complaints are handled by your city or county building department or code enforcement office. For disputes, courts in Washington State handle landlord-tenant cases under the RLTA².

Key Washington State Tenancy Law

• Residential Landlord-Tenant Act (RCW 59.18): Main law for habitability, repairs, basic tenant rights, and landlord duties.

This law covers when repairs must be completed (within 24 hours to 10 days, depending on urgency) and your rights if they’re not.

   City or county building/code enforcement agencies respond to complaints. For legal disputes, Washington courts apply the RLTA.
