RRIO Inspections Explained

Understanding Seattle's Rental Registration and Inspection Ordinance.

8 min readUpdated Dec 2026

RRIO stands for Rental Registration and Inspection Ordinance—Seattle's program requiring rental properties to register with the city and undergo periodic safety inspections. Here's what it means for you as a renter.

What is RRIO?

RRIO is a Seattle program that:

  • Requires all rental properties to be registered with the city
  • Mandates safety inspections every 5-10 years
  • Ensures rentals meet minimum housing standards
  • Creates a public database of registered rentals

The program was designed to protect tenants by ensuring rental properties are safe and habitable.

What Do Inspectors Check?

RRIO Inspection Checklist

  • Smoke & CO detectors — Working and properly placed
  • Heating system — Functional and safe
  • Electrical system — No hazards, proper grounding
  • Plumbing — Hot/cold water, no leaks
  • Structural integrity — Floors, walls, ceilings
  • Windows & doors — Operable, secure, egress
  • Weather protection — No leaks, proper weatherization
  • Common areas — Safe stairs, handrails, lighting

What Does Registration Status Mean?

Registered & Compliant

The property is registered with the city and has passed its most recent inspection. This is what you want to see.

Registered — Inspection Pending

The property is registered but awaiting inspection. This isn't necessarily bad—the program schedules inspections over time.

Not Registered

Red flag. The property is not registered with RRIO. This could mean the landlord is operating illegally or avoiding inspections.

Why RRIO Matters to Renters

RRIO Protects You By:

  • • Ensuring basic safety standards are met
  • • Creating accountability for landlords
  • • Providing a record of property compliance
  • • Identifying landlords who cut corners
  • • Giving you leverage if issues arise

What If a Property Isn't Registered?

Red Flags for Unregistered Properties

  • • The landlord may be operating illegally
  • • The property may not meet safety standards
  • • You may have fewer protections if problems arise
  • • It could be a scam listing

If you discover a property isn't registered, you can:

  • Ask the landlord — There may be a legitimate reason (new conversion, in process)
  • Walk away — Consider it a red flag and find another place
  • Report it — Contact the Seattle Department of Construction & Inspections (SDCI)

Properties Exempt from RRIO

Some properties are exempt from RRIO:

  • Owner-occupied buildings with fewer than 2 units
  • Hotels and motels
  • Certain subsidized housing
  • Properties outside Seattle city limits

How Often Are Inspections?

RRIO inspections occur on a cycle:

  • Initial inspection — Required when first registered
  • Subsequent inspections — Every 5-10 years depending on compliance history
  • Re-inspection — If issues are found, follow-up inspection after repairs

What RRIO Means for Current Tenants

If you already live in a rental:

  • You'll be notified — Before an inspection, tenants are typically notified
  • Inspectors need access — Landlords must provide access to units
  • Issues must be fixed — If problems are found, landlords must repair them
  • No retaliation — Landlords cannot retaliate against tenants related to inspections
