Rental Licensing Requirements by City in 2025
If you’re a landlord in Washington State — especially in places like Seattle, Kenmore, or Redmond — you might be wondering:
Do I need a business license to rent out my property?
The answer is yes, in many cases — and failing to get one could put you at risk of fines, legal action, or blocked evictions.
Let’s break down what Washington landlords need to know in 2025.
Key Takeaway
Yes — many Washington landlords do need a business license, depending on where the property is located. With laws tightening in 2025, it’s essential to stay current on city-specific rental compliance requirements. As the Rental Housing Association of Washington (RHAWA) emphasizes, proactive compliance “helps avoid litigation, improve tenant relations, and protect long-term rental income.”
Statewide vs. Local Licensing Requirements
Washington State does not have a universal rental business license, but many cities and counties do. These licenses often go beyond basic registration — they’re tied to rental inspections, housing standards, and local compliance rules.
In fact, according to NOLO’s legal guide for landlords, “Many cities in Washington require landlords to obtain a local business license to operate legally.” The specific obligations vary widely by jurisdiction.
If you’re self-managing your rentals, our guide to professional property management services in Seattle outlines how local managers handle legal compliance on your behalf.
Common Local Licensing Requirements for Landlords
Seattle (RRIO Program)
- License Required: Yes, through the Rental Registration & Inspection Ordinance (RRIO)
- Applies to: All non-owner-occupied rental properties
- What’s required:
- Initial RRIO registration
- Periodic property inspections (typically every 5 to 10 years)
- Fees based on number of units

The City of Seattle states: “The RRIO program helps ensure that all rental housing in Seattle is safe and meets basic maintenance requirements.” Failure to register may result in penalties, citations, and even denial of evictions.

Redmond, Kirkland, Bellevue
- License Required: Yes
- What’s required:

The Washington State Department of Revenue confirms that a general business license is required in most cities when engaging in rental activity, even for a single property.
Unincorporated King County
No rental license required, but landlords must still report rental income and may be subject to zoning or inspection rules. It is always recommended to verify with the King County Permitting Division for current requirements.

The Washington State Department of Revenue also confirms these local business license needs.
Consequences of Not Having a License
Not having a required rental license may result in:
- Civil fines or penalties
- Inability to enforce lease terms or evict legally
- Legal liability for code violations
- Tenant complaints escalating to city legal departments
The Seattle Department of Construction & Inspections has stated that landlords who operate unregistered properties “may be prohibited from enforcing eviction actions” until they comply.
In a recent article by Avail, the author explains:
“Failing to obtain the appropriate business licenses could lead to costly legal consequences or an inability to legally enforce lease agreements.”
