Seattle's Rental Registration and Inspection Ordinance (RRIO) requires nearly every residential rental property in the city to be registered with the Seattle Department of Construction and Inspections (SDCI). Registration currently costs $126 per property, which includes the first unit, plus $31.50 for each additional unit, and it must be renewed every 2 years. Each registered property must also pass a checklist-based safety inspection at least once every 5 to 10 years. Owners who skip RRIO face penalties of $150 to $500 per day and cannot evict tenants from unregistered units.
If you own a rental in Seattle, RRIO is not optional paperwork; it is a core compliance requirement for operating a rental in the city.
The program is straightforward once you understand the cycle. Here is what RRIO requires, what it costs, how inspections work, and what happens when owners ignore it.
The Rental Registration and Inspection Ordinance, codified at Seattle Municipal Code Chapter 22.214, was established by the Seattle City Council after an extensive public involvement process. Its purpose is simple: make sure every rental home in Seattle is safe and meets basic housing maintenance standards.
Before RRIO, the city only learned about substandard rentals when a tenant complained. RRIO flips that model. Every rental property registers with SDCI, and inspectors verify that registered properties meet minimum housing and safety standards at least once every 5 to 10 years.
For owners, the program does three useful things:
If you rent out residential space in Seattle, you almost certainly must register. RRIO covers single-family homes, accessory dwelling units, duplexes, triplexes, fourplexes, townhomes, condos, and apartment buildings of any size. If you are renting out your home in Seattle for the first time, registration belongs at the top of your checklist.
Timing matters:
Exemptions are narrow. SDCI notes that some government-owned, government-operated, and institutional rental housing may not need to register, and the city publishes a registration exceptions list for those cases.
A typical private owner with a house, a condo, or a small building does not qualify for an exemption. When in doubt, check with SDCI before assuming you are exempt; the penalty math makes guessing expensive.
Registration runs through the Seattle Services Portal, though you can also register by mail or in person. To complete it, you will need:
When you register, you declare that the property and its rental units meet the standards in the city's RRIO Checklist. That declaration is not a formality; it is the standard your property will be inspected against later.
Current fees, per SDCI: $126 for a property, which includes the first rental unit, plus $31.50 for each additional unit at the same property. A single-family rental is $126, a duplex is $157.50, and a 10-unit building is $409.50. These amounts include a 5 percent SDCI technology fee.
The renewal cycle: your registration is good for 2 years from the date you register. SDCI reaches out by mail and email roughly 60 days before expiration, using the contact information on file, and you must renew by the expiration date on your certificate. Renewal costs the same as initial registration. You are also required to post your RRIO registration certificate in a common area of the property or give a copy to each tenant.
One practical warning: that 60-day reminder only works if your contact information is current. Owners who move, change email addresses, or transfer the property into a new entity routinely miss renewal notices, and the registration quietly lapses. Keep your contact information current with SDCI; the reminder is only as good as the address on file.
Registration is half the program. The other half is inspection, and this is where preparation pays off.
How often. Every property must meet the inspection requirement at least once every 5 to 10 years. Properties are selected for inspection once during the first five years after registration, and there is a 10 percent chance of being chosen a second time within the following five years. SDCI notifies a random selection of owners every month, and the notice gives you at least 60 days to complete the inspection.
How many units. For multi-unit properties, you may have every unit inspected or a random sample of 20 percent of units. If you choose the sample, you can contact the RRIO program 10 days before the scheduled inspection to learn which units were selected.
Who can perform it. You may hire a City inspector or a qualified private inspector from the city's published list. City inspections currently cost $241.50 for the property and first unit, plus $52.50 for each additional unit, with up to two follow-up re-inspections at no extra charge. Private inspectors set their own rates, must hold a recognized certification and complete city training, and the city charges a $63 filing fee to process private inspection results.
Tenant notice. Once an inspection is scheduled, you must give your renters at least two days' written notice. The city provides a notification template.
What inspectors check. Inspections follow the RRIO Checklist, which covers basic life-safety and habitability items. The most common failures SDCI sees are:
These are inexpensive fixes that a routine walkthrough catches long before an inspector does. Owners who keep up with regular property inspections rarely fail RRIO, because the failures are almost always deferred small maintenance, not major systems.
If your property passes, you receive a Certificate of Compliance. If it fails, you make the corrections and have it re-inspected. Properties already inspected under qualifying programs, such as Seattle Housing Authority voucher inspections or certain Office of Housing, state, county, or HUD programs, can submit that documentation instead of a new RRIO inspection.
This is where RRIO grows teeth. SDCI can issue a violation for failing to register by the due date, failing to complete an inspection by the due date, or renting units that do not meet the RRIO Checklist standards.
Penalties are $150 per day for the first 10 days and $500 per day after that. A violation left unresolved for a month has already passed $11,000, and SDCI refers uncorrected cases to the City Attorney's office for a lawsuit to compel compliance and collect penalties.
The quieter consequence is often worse. Under Seattle's just cause eviction provisions in SMC 22.206.160, an owner may not evict a residential tenant from a rental unit that is not registered under RRIO, regardless of whether just cause for eviction exists.
The code treats an owner as compliant if the unit is registered before the court enters an order, but discovering a lapsed registration in the middle of an eviction means delay, added legal expense, and leverage handed to the other side at the worst possible moment.
An unregistered rental in Seattle is a property you cannot fully enforce your own lease on. That alone justifies treating RRIO as a standing compliance item, not a one-time task.
RRIO is the entry ticket, but it is only one layer of what Seattle and Washington require of rental owners. The current stack includes, among other things:
RRIO interacts with all of it. Registration status gates your ability to evict, inspection standards overlap with your habitability duties, and the certificate posting requirement is part of tenant disclosure.

Per SDCI's current fee schedule, registration is $126 for a property, which includes the first rental unit, plus $31.50 for each additional unit at the same property, including a 5 percent technology fee. Registration lasts 2 years, and renewal costs the same.
At least once every 5 to 10 years. Your property will be selected once during the first five years after registration, with a 10 percent chance of a second selection in the following five years. You get at least 60 days' notice to complete it.
Yes. RRIO covers essentially all residential rentals in Seattle, including single-family homes, condos, ADUs, and small multifamily buildings. It also covers short-term rentals that are not the operator's primary residence. Only limited categories, mostly government and institutional housing, are excepted.
Yes. You may hire a City inspector through SDCI or select a qualified private inspector from the city's published list. Private inspectors set their own rates, and the city charges a $63 filing fee to process private inspection results.
Register now, before SDCI issues a violation. Penalties run $150 per day for the first 10 days and $500 per day after that, and you cannot evict a tenant from an unregistered unit under SMC 22.206.160. Registering promptly, even late, restores your standing.
