Seattle short-term rental licensing guide
Last updated: October 13, 2026
Seattle treats a home, or part of a home, rented for a fee for fewer than 30 consecutive nights as a short-term rental. Running an Airbnb, Vrbo, or other STR in Seattle is not just a matter of listing a room and collecting bookings. Seattle has a specific short-term rental regulatory license, a separate city business license tax certificate, unit and ownership limits, land-use rules, and an extra rental-registration step for many dedicated units.
Washington also treats short-term lodging as taxable business activity and has its own safety, insurance, and lodging rules. This guide shows the order in which to check those layers and where to apply.
Bottom line
If the rental property is inside Seattle city limits and you are operating a short-term rental, the normal city path has two separate licenses: a Seattle business license tax certificate and a Short-Term Rental Operator regulatory license. The city tells new operators to get the business license tax certificate first, determine whether Rental Registration and Inspection Ordinance registration applies, and then apply for the STR operator license through the Seattle Services Portal.
Do not stop at the licenses. You also need to confirm that the space is a legal dwelling unit where short-term rental use is allowed, follow Seattle’s unit and ownership rules, handle Washington lodging taxes and reporting, and check state safety and insurance requirements that apply to your setup.
Quick start: do these checks in this order
- Confirm the property is inside Seattle city limits.
- Confirm operator eligibility. Seattle generally licenses owners, with limited legacy exceptions.
- Get the Seattle business license tax certificate.
- Check RRIO. A dedicated non-primary STR generally needs RRIO before the STR license.
- Apply for the STR Operator License through the Seattle Services Portal.
- Check the space and land use. Not every room, structure, or location can be used as an STR.
- Set up Washington tax, safety, and insurance compliance.
Seattle short-term rental license and permit map
| Requirement | Government layer | When it matters | Action |
|---|---|---|---|
| Seattle business license tax certificate | City of Seattle | Core city business-license step for Seattle STR operators | Review the city business-license page |
| Short-Term Rental Operator License | City of Seattle | Required to operate a Seattle STR under the city program | Apply in the Seattle Services Portal |
| RRIO registration | Seattle Department of Construction and Inspections | Generally applies to dedicated STR units that are not the operator’s primary residence | Check RRIO owner requirements |
| Land-use and dwelling-unit eligibility | Seattle Department of Construction and Inspections | Before listing any room, apartment, ADU, DADU, condo, or other space | Check Seattle STR land-use rules |
| Washington business/tax registration | Washington Department of Revenue | Transient lodging is taxable; registration and reporting can apply even when a platform collects some taxes | Use the state Business License Application guidance |
| State STR safety and liability rules | Washington State | When the rental falls within Chapter 64.37 RCW’s STR definition | Read Chapter 64.37 RCW |
| Transient accommodation license | Washington Department of Health | Facilities offering three or more lodging units for stays under 30 days | Check state transient-accommodation licensing |
First confirm the property is inside Seattle city limits
Do not rely only on the postal city name. Some addresses use “Seattle” even when the property is outside the incorporated city. Seattle publishes an official boundary-map route that lets you search an address and see whether it falls within city limits.
If the property is outside Seattle, this article’s Seattle regulatory-license path may not apply. Start with the government that has jurisdiction over the exact property. BLG’s King County business license guide explains the city-versus-unincorporated-county split, while the Seattle business license guide covers the broader city license map for businesses that are actually in Seattle.
You can use the City of Seattle’s city-limits map instructions as an official address check.
The two Seattle licenses are separate
1. Seattle business license tax certificate
Seattle requires the general business license tax certificate before the STR regulatory license. The city directs applicants to FileLocal to apply, renew, manage the account, and file city tax returns.
For 2026, Seattle lists the lowest annual business-license fee tier at $73 for annual Seattle taxable revenue below $20,000. New applicants generally start in the lowest tier; higher renewal tiers apply as taxable revenue increases.
2. Short-Term Rental Operator License
Apply through the Seattle Services Portal. The current fee is $75 per licensed dwelling unit, and the license is valid for 12 months from issuance. That renewal date is different from the December 31 cycle for the general business license.
Seattle tells first-time applicants to allow 48 hours after first applying for the business license certificate before applying for the STR license.
Choose the right license type. The Seattle Services Portal has separate applications for a Short-Term Rental Operator License, a Bed and Breakfast Rental Operator License, and a Platform License. The platform license is for companies that facilitate bookings, not individual hosts.
Put the city license number on the listing
Seattle requires the STR operator license number on every listing in the format STR-OPLI-##-######. Platforms may remove listings when the number is missing or formatted incorrectly.
Seattle’s ownership and unit limits change the business model
For most operators, Seattle allows up to two dwelling units you own as STRs. If you operate two, one must be your primary residence. Rooms inside one licensed dwelling unit do not become separate dwelling units just because they are listed separately.
The operator license must be in the property owner’s name even if a management company handles the listing or guests.
Renters are a special case
Landlord permission does not normally make a renter eligible for an STR operator license. Seattle lists a narrow legacy exception for certain Downtown Urban Core units operating before September 30, 2017.
Legacy units have separate rules
Some legally operating pre-September 30, 2017 units can qualify for special provisions and extra documentation. Because the result depends on the unit, location, ownership history, and old rental records, use the City’s current STR guidance rather than assuming grandfathered status transfers.
2026 code note: Seattle Ordinance 127375 took effect January 21, 2026 and amended SMC 6.600.040 as part of the One Seattle Plan update. The normal rule remains one STR dwelling unit, or up to two if one is the operator’s primary residence. The amendment updates comprehensive-plan geographic references used in some legacy exceptions. If you rely on a pre-September 30, 2017 exception, use the current code and current maps rather than an older “Urban Center” label.
ADUs and DADUs are separate dwelling units
Seattle treats an ADU or DADU as a separate dwelling unit for STR licensing. A dedicated ADU or DADU can also trigger RRIO, so count dwelling units before applying.
RRIO, zoning, and the exact space matter before you list
RRIO for dedicated units
If you rent your primary residence as an STR, Seattle says you do not have to register that primary residence in RRIO solely because of the STR use, although the home still must meet basic habitability requirements. A dedicated STR that is not your primary residence generally must be registered and compliant with RRIO. Seattle specifically includes dedicated accessory dwelling units in this rule.
Do this check before the STR license application. The city lists RRIO registration as a prerequisite when it applies.
Not every space can be a Seattle STR
Seattle’s land-use guidance says STRs are allowed in most structures legally established as dwelling units. It also lists spaces where STR use is not allowed. These include RVs, tents, garages, boats, live-work units, dwellings in commercial or industrial buildings permitted as caretaker’s quarters, and certain over-water or shoreline locations where lodging is prohibited.
The unit also must comply with applicable parking, noise, housing, building-maintenance, and safety rules. A city business license or STR operator license does not legalize an unapproved sleeping space or override the Land Use Code.
Private permission is separate
A city license does not override a lease, condominium declaration, homeowners-association rule, mortgage condition, or insurance restriction. Check those private restrictions before spending money on licensing or furnishing the unit.
Washington adds safety, insurance, tax, and sometimes health licensing
State safety and liability rules
When Chapter 64.37 RCW applies, the operator must provide a guest contact available during the stay, comply with carbon-monoxide-alarm rules, and post the property address, emergency information, escape-route floor plan, maximum occupancy, and operator or designated-contact information.
The same chapter requires at least $1 million in primary liability insurance, unless each transaction is conducted through a platform providing equal or greater primary coverage.
The state definition has an owner-occupied room exception
Chapter 64.37 excludes a dwelling unit occupied by the owner at least six months during the year when fewer than three rooms are rented at any time. That state-law exception does not automatically erase Seattle’s city licensing rules. Owner-occupied room hosts should check both definitions.
Three or more lodging units can trigger Department of Health licensing
Washington’s transient-accommodation rules apply to facilities offering three or more lodging units for stays under 30 days. If your setup reaches that threshold, check the Department of Health licensing program before advertising.
Taxes: platform collection does not mean the host is finished
Washington treats personal home rentals under 30 days as taxable lodging. DOR says owners may need to register, must handle retail sales tax when responsible for collection, can owe lodging taxes based on location, and report the activity under Retailing B&O.
King County lodging can also be subject to convention and trade center tax. Use Washington DOR’s location-based rate tools rather than copying another listing’s tax rate.
If Airbnb or another marketplace collects tax
DOR says Airbnb collects state and local retail sales tax, special hotel/motel taxes, and convention and trade center taxes for Airbnb hosts. Even then, a host may still have state registration, reporting, and B&O duties. If registered, report rental income and use the facilitator deduction as DOR instructs.
Seattle city B&O changed in 2026
Beginning January 1, 2026, Seattle’s Seattle Shield B&O changes raised the city taxable-revenue threshold from $100,000 to $2 million and added a $2 million standard deduction. Businesses below the threshold still file Seattle business-license tax returns. This can change tax due without removing the business license or STR operator license.
Seattle also notes that its separate planned STR tax was repealed in 2018; Washington sales and lodging taxes still apply.
Coming January 1, 2027
Seattle’s published schedule lists the lowest general business-license tier at $76 for 2027, up from $73 in 2026. This is separate from the $75 STR operator-license fee.
Real-world Seattle examples
You own and live in a Seattle house and rent one bedroom
Check the Seattle business license and STR operator license. RRIO generally is not required solely for STR use of your primary residence. Also check whether Washington’s owner-occupied-room exception applies to the state STR chapter.
You own a Seattle condo that is not your primary residence
This is a dedicated STR. It normally needs both city licenses and RRIO, and it counts as a secondary dwelling unit under the normal two-unit framework. Condo documents and insurance are separate checks.
You live in the main house and rent a backyard DADU
The DADU is a separate dwelling unit. Treat it as its own STR unit and check RRIO, legal establishment of the unit, and land-use eligibility.
You rent an apartment and the landlord says Airbnb is fine
Landlord permission alone is not enough. Seattle generally does not license renters as STR operators outside the narrow Downtown legacy exception.
If you are choosing an LLC, trade name, or sole proprietorship, see BLG’s business license vs. LLC vs. DBA vs. seller’s permit guide and Washington business license guide.
Common mistakes that can cost time or money
- Getting only one city license. Seattle requires the business license tax certificate and the STR operator license.
- Skipping RRIO on a dedicated unit.
- Assuming a Seattle mailing address proves city jurisdiction.
- Listing a garage, RV, boat, live-work unit, or other prohibited space.
- Treating an ADU or DADU as just another room.
- Assuming landlord permission makes a renter eligible.
- Forgetting the two city licenses renew on different schedules.
- Leaving the STR license number off the listing.
- Assuming a platform handles every tax and filing.
Seattle currently lists a $500 penalty for a first STR regulatory-license violation and $1,000 for later violations, plus a $513 citation for operating without the required Seattle business license tax certificate.
Compact compliance checklist
- Verify Seattle city limits and operator eligibility.
- Count dwelling units and identify the primary residence.
- Check lease, condo, HOA, mortgage, and insurance restrictions.
- Get the Seattle business license tax certificate.
- Complete RRIO first when it applies.
- Confirm SDCI land-use eligibility for the exact space.
- Apply for the STR operator license and post its number on listings.
- Set up Washington tax reporting as required.
- Check Chapter 64.37 safety and insurance rules.
- Check Department of Health licensing if offering three or more lodging units.
- Calendar both city renewal dates.
What to ask Seattle before you spend money
For an unusual setup, give the City the facts that determine the license path.
Phone or email script
“I want to operate a short-term rental at [property address]. I [own / rent] it. It is [my primary residence / not my primary residence]. The space is [a room / whole dwelling / ADU / DADU / condo]. Can you confirm operator eligibility, whether RRIO is required before I apply, and whether there is a legacy or land-use issue to resolve first?”
Seattle currently lists STR customer service at 206-386-1267 and STR@seattle.gov. Route zoning and dwelling-unit questions to Seattle Department of Construction and Inspections.
What if the normal path does not work?
If the portal blocks the application, first confirm the business license is active, RRIO is complete when required, and the property fits the eligibility rules. Ownership, primary-residence, legacy-unit, and business-entity questions belong with the STR licensing team; dwelling-unit and land-use questions belong with SDCI.
If the property is outside Seattle, stop using the Seattle STR path and identify the correct city or unincorporated King County rules.

FAQ
Do I need both a Seattle business license and a short-term rental license?
Yes. Seattle’s current STR process requires a Seattle business license tax certificate and a separate Short-Term Rental Operator regulatory license. The business license tax certificate comes first.
How many short-term rental units can I operate in Seattle?
Most operators may operate up to two dwelling units they own as short-term rentals. If you operate two, one must be your primary residence. Limited legacy exceptions can apply to certain units that were operating before September 30, 2017.
Can a Seattle renter get an Airbnb or short-term rental operator license?
Usually no. Seattle says renters may not obtain STR operator licenses except for a narrow Downtown Urban Core legacy situation involving units that were operating as short-term rentals before September 30, 2017.
Do I need RRIO for a Seattle short-term rental?
Your primary residence generally does not need RRIO registration solely because you use it as a short-term rental. A dedicated STR that is not your primary residence generally must be registered and compliant with RRIO before the STR regulatory-license application.
Does Airbnb collecting taxes mean I do not need a Washington tax account?
No. A marketplace may collect and remit some sales and lodging taxes, but Washington says a host may still have registration, reporting, and B&O tax duties. Check your platform agreement and your Department of Revenue account requirements.
Can I use a garage, RV, boat, or live-work unit as a Seattle short-term rental?
Seattle’s land-use guidance says short-term rentals must generally be in legal dwelling units and specifically bars STR use in several categories, including RVs, tents, garages, boats, live-work units, caretaker’s quarters, and certain shoreline or over-water locations.
