Rental Registration and Inspection Ordinance (RRIO)

The Rental Registration and Inspection Ordinance (RRIO) is a recently established law pertaining to rental properties within the city of Seattle. As of 2014, landlords with rental properties in Seattle ranging from single-family homes to large apartment buildings are required to register their properties with Seattle’s Department of Planning and Development to ensure that they conform to basic housing and safety standards. 

How Will RRIO Benefit Seattle Residents?

• Periodic inspections will ensure that all rental properties in the city of Seattle meet minimum housing standards.
• Neighborhoods and rental housing units within Seattle city limits will be improved and maintained through RRIO code compliance.
• Informing landlords, inspectors, and renters of RRIO rules will encourage and sustain thorough rental housing maintenance.

When is Registration Due?

• Properties with 10 or more units were required to register by September 30, 2014. 
• Properties with 5 - 9 units must register by March 31, 2015. 
• Single-family, duplex, triplex, and fourplex rental properties have registration deadlines throughout 2015 and 2016. Due dates vary based on the ZIP code in which the rental property is located. Late fees will be charged to property owners who do not register by their specific due date. View the complete schedule of registration deadlines here.
