Rental Registration and Inspection Programs Near Seattle

LearnFacts checked November 8, 2026Reviewed by Gary E. Wilson, President and Designated Broker

Why cities run these programs, and the state limits

A rental registration program gives a city a current list of rentals and who is responsible for them. An inspection program goes further and checks units against a basic health and safety checklist. Some cities do this through a business license instead of a separate registration.

Washington sets the outer limits in RCW 59.18.125. Under that statute:

• A city may require a certificate of inspection as a business license condition, or without a license program.
• A city may require a certificate of inspection on a rental property only once every three years.
• A property with a certificate of occupancy from the last four years and no reported code violations in that time is exempt.
• For a property with twenty or fewer units, the city may select no more than four units, unless an inspected unit fails or health and safety problems were reported.
• If only some units are inspected, the owner must send written notice to every unit, and entry follows the state notice rules.
• Cities must offer an appeal, may set penalties, and may tell a landlord it is unlawful to rent the unit until a certificate is provided.

Seattle: RRIO covers almost every rental

Seattle's Rental Registration and Inspection Ordinance, called RRIO, is the broadest program in the area. The city's RRIO owners page says rental properties, with a few exceptions, must be registered as soon as they have a tenant. That includes a single rental house.

Registration lasts two years. The listed fee for a one-unit property, such as a single-family home, is $126, with more for each added unit. You must post the registration certificate in a common area or give each tenant a copy.

Properties are selected for inspection once during the first five years after registration, with a smaller chance of a second selection in the following five. After notice, you get at least 60 days to complete it, using a City inspector or a qualified private inspector, and tenants get at least two days' notice. The page lists common failures such as missing or broken smoke or carbon monoxide alarms and missing handrails or guardrails.

Skipping RRIO is costly. The city lists penalties of $150 per day for the first 10 days and $500 per day after that. Seattle's just cause eviction page also says a landlord ending a covered tenancy must be in compliance with RRIO.

Other King County cities we confirmed

Each of these programs is described on the city's own website or in its municipal code, as checked on the "Facts checked" date shown on this page:

• Renton. The city's rental registration page says landlords must register residential rentals, including renter-occupied single-family homes and condos, every year on or before January 1. It says registration is currently free, and that inspections follow reported violations.
• Kent. Kent Municipal Code chapter 10.02 requires registration of rental units that are not exempt, such as owner-occupied single-family homes. A registration expires on December 31 of the year after it is issued or renewed. The business license and the inspection every three years apply to covered properties, but single-family homes, condos and townhomes are exempt from the license.
• Burien. The city's Rental Housing Inspection Program requires an inspection every three years for apartments and duplexes through fourplexes, by a private inspector from the city's list. Single-family homes, condos, townhomes and accessory dwelling units are exempt.
• Auburn. The city's rental housing page says most rentals need a Rental Housing License. It lists a city business license for a non-owner-occupied home rented on one lease, with no inspection listed for that type.
• Tukwila. A city rental housing inspection procedure describes City and City-approved private inspections under Tukwila Municipal Code 5.06, with City inspectors serving properties of 12 or fewer units.

Cities not listed here

Wilson Management's areas we serve page covers many more cities, including Bellevue, Kirkland, Redmond, Everett and Federal Way. That page also lists south Snohomish County cities such as Lynnwood, Edmonds and Mill Creek. This guide names only programs we could confirm on a city's own website or code, and we did not confirm one for any Snohomish County city. If a city is not listed, that does not mean it has no rule. Check the city's code and business license page before you rent.

Also check whether the address is inside city limits at all. A home with a city mailing address can sit in unincorporated King County, where city programs do not apply and county code does. The Seattle vs Eastside rules guide covers other local layers, such as notice periods and move-in fee limits.

How a property manager usually handles it

Registration is mostly calendar work: knowing which program applies, renewing on time, keeping certificates on file, and telling the city when ownership or contact details change. Inspections take more care. Tenants need proper written notice, the right units need to be ready, and any failed item needs a repair and a re-inspection. When you hire or change managers, update the contact on file too. Seattle's RRIO page has separate steps for updating contact information and for transferring ownership.

A city or program inspection is separate from the move-in, periodic and move-out inspections a manager does for the tenancy. Seattle, for example, requires a City inspector or a qualified private inspector. Wilson's rental property inspections page describes its own condition inspections, and Seattle landlord laws covers RRIO alongside the city's other rules.
