Rental Registration & Inspection Code

What Is It?

The Rental Registration and Inspection Ordinance (RRIO) helps ensure that all rental housing in Seattle is safe and meets basic housing maintenance requirements. The program educates property owners, managers, and renters about City housing codes and their responsibilities; and requires owners to verify that their properties meet these standards when registering with the City.


  • The Rental Registration and Inspection Ordinance requires landlords to register all rental housing units in Seattle, from single-family houses to large apartment buildings.
  • Exceptions to the registration requirement include commercial lodging, state-licensed facilities such as adult family homes, and housing owned by government groups or by housing authorities such as Seattle Housing Authority. See the ordinance for more detail.
  • Landlords must register their properties as soon as they have a tenant in the rental space.
  • Registrations must be renewed every 2 years.


  • The ordinance requires that all registered rental properties be inspected at least once every 10 years.
  • The owner must hire a qualified rental housing inspector or City inspector to do the inspections.

This ordinance does not cover complaint-based enforcement of City housing standards. We will continue our complaint-based process for housing code violations. Our City housing and zoning inspectors will continue to enforce all housing code standards and other applicable codes.

The best way to register your property is to use our online registration program. Please read the instructions listed below before you register. You may also register in person or by mail using the Registration Form in the list below. When you register your property, you will be asked to declare that the property and available rental units meet the standards described in the RRIO Checklist.

When are the Registration Due Dates?

Landlords must register their properties as soon as they have a tenant in the rental space. 

Some government-owned, government-operated, and institutional rental housing may not need to be registered. Find out if your property may meet the registration exceptions.

What You Will Need

To register a property, you will need some basic information about the property:

  • Property information and address.
  • Information for three contact types for each property registered: Applicant, Owner(s), and Tenant Contact for Repair.
  • The number of rental units on your property. Unit numbers must be provided.

What are the Registration Fees?

The fee is $70 for a property and its first rental unit, plus $15 for each additional unit. For example:

  • A 1-unit rental property, like a single-family home, is $70
  • A 2-unit rental property is $85
  • A 10-unit property is $205

Payments can be made by credit card, check, or cash. Our online registration system only accepts payment by credit card. If you wish to pay your registration fee using a check after registering online (but before payment), follow these instructions for paying by check. Once you have registered, you will receive a receipt and a RRIO registration certificate.

Your RRIO registration is good for 2 years from the date you register your property. You are required to post your RRIO registration certificate in a common area of your rental property or give a copy to each tenant.

We require all rental properties to be inspected periodically, or show that they meet the inspection requirement some other way. Properties are selected for inspection at least once during the first ten years after they are registered. There is a 10 percent chance the property will be chosen a second time within the following 5 years. Properties with more than one unit will have 20 percent of the rental housing units inspected, rounded up to the nearest whole number, up to a maximum of 50 rental housing units in each building. Every month, we will notify a random selection of property owners that we have selected their property for inspection. Our notice will give you at least 60 days to have the inspection completed. Multifamily property owners can contact the RRIO program 10 days prior to the scheduled inspection date to learn which units have been selected for inspection. 

Meeting the RRIO Inspection Requirement

When you receive a Notice of Required Inspection, you have three ways to meet the inspection requirement:

1. Complete a RRIO Inspection

  • Hiring an Inspector: You may hire City inspectors or qualified private inspectors to complete an inspection.
    • To hire a City inspector, call (206) 684-4110 and select option 3 when prompted. City inspections cost $175, which includes the first unit. Inspections for more than one unit cost an additional $35 per unit. City inspectors will perform follow-up inspections, as needed, at no charge. 
    • To hire a qualified private inspector, choose one from this list of available private inspectors. Private inspectors set their own rates. The City does require a $40 filing fee for processing private inspection results.
  • Notifying Renters: Once you have scheduled an inspection, you must give your renters at least two days notice of the inspection. You may prepare your notices using this Notification to Tenants of a RRIO Inspection template.
  • Passing the Inspection: Once your property passes the RRIO inspection, you will receive a Certificate of Compliance from either your city or private inspector. You are required to post your RRIO registration certificate in a common area of your rental property or give a copy to each tenant. 
  • Failing the Inspection: If your property does not pass the inspection, you need to make the required corrections and then have the property reinspected. City inspectors will conduct up to 2 reinspections at no charge. Private inspectors will set their own rates.
  • Extending the Inspection Deadline: You may request more time to complete your inspection. To request more time, call (206) 684-4110.

Other Types of RRIO Inspections

There are other types of RRIO inspections that may be done voluntarily, or as a result of a complaint.

Pre-Registration Inspection
You may choose to hire a City inspector or qualified private inspector to complete an inspection prior to registration. A pre-registration inspection can help you feel confident declaring that your property and all your units meet our checklist standards. This inspection is strictly voluntary and all rental housing units on your property must be inspected. You must comply with all the requirements of our required inspection, such as proper notice to tenants. If you complete and pass a pre-registration inspection, the inspector will provide you with a Certificate of Compliance. The RRIO Certificate of Compliance for a pre-registration inspection will satisfy your inspection requirement for at least five years. Instructions for submitting your documents are located below.

Voluntary Inspection
You may choose to have a RRIO inspection conducted after you register at your convenience, rather than wait to be selected for a required inspection. To schedule a voluntary inspection, you must contact us at (206) 684-4110 and request a voluntary inspection letter. The letter will establish the date for your 60-day compliance timeline. It will also randomly select the appropriate number of units on a multi-unit property to be inspected which cn be provided 10 days prior to the scheduled inspection date. If you have prior violations you may be required to have all your units inspected, depending upon the date of the violation. You may hire a City inspector or a qualified private inspector to complete the voluntary inspection. If you complete and pass the voluntary inspection, the inspector will provide you with a Certificate of Compliance. You may submit the certificate to us and that will satisfy your inspection requirement for at least five years. Instructions for submitting documentation are located below.

Complaint-Based Inspection
All complaints regarding rental housing will be handled according to the Housing and Building Maintenance Code, enforced by our Code Compliance group. This code has a broader set of standards than RRIO.

If a City Housing and Zoning Inspector completes a site inspection of the property, the inspector will also complete a RRIO Checklist.

  • If the rental unit(s) pass the RRIO Checklist, then the result will be recorded with the property registration record and no additional action will be necessary regarding the complaint.
  • If the rental unit(s) fail the RRIO Checklist and the property is not required to be registered with us, then the property will be managed according to the practices, procedures, and policies of our Code Compliance program.
  • If the rental unit(s) fail the RRIO Checklist and the property is registered with us, then the result will be recorded with the property registration record and us. If the property is randomly selected for inspection in the next year, all units on the property must be inspected.

If the Department Director requires additional RRIO inspections of rental housing units due to a failed RRIO Checklist, the additional inspections must be completed within 60 calendar days.

Submitting Inspection Documents

You will need to submit documents to us that you have met the inspection requirement if:

  • You have documentation of a pre-qualified alternate inspection (listed in the table above)

There are 3 ways to submit proof that you passed your inspection:

  1. Email: Scan and attach your documents to an email and send them to
  2. Mail: Mail your documents to:
         City of Seattle - Seattle Department of Construction and Inspections
         RRIO Program
         P.O. Box 34019
         Seattle, WA 98124-4019
  3. In Person: Bring your documents to:
         Seattle Municipal Tower
         700 5th Avenue
         Applicant Service Center - 20th Floor
         Seattle, WA 98124

If you do not follow our requirements, we may issue a violation and penalties, and we may take legal action. Our goal is to work with you to make sure you meet our requirements. If you face RRIO penalties or a violation, call us immediately to resolve the situation before the penalties grow and become a costly lawsuit.

You may get a violation for:

  • Not registering a rental housing property by the due date
  • Not completing a property inspection by the due date
  • Renting a property to tenants that does not meet the minimum standards in the RRIO checklist

Penalties are $150 per day for the first 10 days and $500 per day after that.

Once you receive a Notice of Violation letter, you must comply or contact us immediately if you need an extension or want to appeal. You may request a review of the violation of penalties by following these instructions to file an appeal.

If you do not comply or request a review, we will send the case to the City Attorney’s office to file a lawsuit to compel you to meet the RRIO requirement and pay the penalties. We will notify you when we refer the violation to the City Attorney.
