Legality Verdict
Seattle is legal but not frictionless. Legality Grade: B. Investors get an open licensing pathway, a clear $75/unit STR license, and no citywide license cap, but the two-unit operator limit and non-transferable license structure make portfolio underwriting difficult.
TL;DR
Seattle defines a short-term rental as a dwelling unit, or part of one, rented for fewer than 30 consecutive nights under Seattle Ordinance 125490. You need a Seattle business license tax certificate and a Seattle short-term rental operator license before listing, and the STR license costs $75 per unit per year under Seattle FAS guidance. Washington DOR’s Q2 2026 lodging table lists Seattle short-term rentals at a 15.70% total lodging tax rate under the Seattle/King lodging code in the DOR lodging-rate table. The operational constraint is the operator cap: generally one unit, or two if one is your primary residence under Seattle Ordinance 125490. Biggest gotcha: the license is non-transferable on sale under Seattle STR Director’s Rule 3.

| State Accommodations Tax | Washington taxes transient lodging through DOR lodging-sales reporting; transient lodging means lodging for less than one month, and operators must collect sales tax under the Washington DOR lodging guide. |
| Local Accommodations Tax | The DOR Q2 2026 table lists a 7.00% convention center tax component for Seattle short-term rentals in the state lodging-rate table. |
| County/District Tax | King/Seattle short-term rentals use DOR lodging location codes in the Q2 2026 table; no tourism-promotion-area fee is shown for Seattle STRs in the DOR Q2 2026 lodging-rate table. |
| Total Effective Lodging Tax | 15.70% for Seattle short-term rentals in Washington DOR’s Q2 2026 lodging-rate table. |

Regulatory Impact Snapshot
The investable Seattle STR is not priced by the permit fee. It is priced by license eligibility and operating structure. The $75/unit STR license under Seattle FAS is immaterial relative to revenue; the 15.70% DOR lodging-tax stack in the Q2 2026 table is usually a pass-through demand and pricing issue; the actual underwriter’s constraint is the two-unit operator cap, the requirement that one of two units be a primary residence under Seattle Ordinance 125490, and RRIO compliance for dedicated non-primary units under SDCI guidance. For condos, private rules can kill a deal even when the city license is available. Run this market in our Airbnb Calculator →
Frequently Asked Questions
Basics
Is Airbnb legal in Seattle?
Yes. Seattle allows short-term rentals when the operator holds a Seattle business license tax certificate and a short-term rental operator license, and the unit qualifies under the land use rules in the Seattle short-term rental code and SDCI guidance.
What counts as a short-term rental in Seattle?
A Seattle short-term rental is a dwelling unit, or part of one, rented for a fee for fewer than 30 consecutive nights under Seattle Ordinance 125490 and the SDCI short-term rental guidance.
Does Seattle have an annual night cap?
No annual night limit was found in the city sources reviewed. The binding limit is the operator cap: one unit, or two if one is the operator’s primary residence, under Seattle Ordinance 125490.
What is the biggest investor constraint?
The biggest constraint is not the $75 license fee. It is the per-operator cap, non-transferability, primary-residence documentation, RRIO compliance for dedicated units, and private HOA or condo restrictions. Seattle’s own guidance emphasizes the license, unit cap, and RRIO linkages on its STR licensing page.
Licensing
What licenses do I need before listing?
You need a Seattle business license tax certificate and a Seattle short-term rental operator license before operating or listing a Seattle STR, according to Seattle FAS and Seattle Ordinance 125490.
How much does the Seattle STR license cost?
Seattle lists the STR operator license at $75 per unit per year in its FAS short-term rental guidance. The business license tax certificate has separate 2026 revenue-tiered fees, with a $73 minimum tier shown on Seattle’s business license page.
Can I operate more than one Seattle STR?
Usually yes, but only up to two owned dwelling units, and one of the two must be the operator’s primary residence. Seattle’s short-term rental ordinance and FAS guidance describe that cap and narrow legacy exceptions.
Are Seattle STR licenses transferable when I buy a property?
No. Seattle’s STR Director’s Rule 3 says annual licenses are non-transferable, and a change of ownership requires a new license application. Underwrite every acquisition as a fresh licensing event.
Can renters operate short-term rentals in Seattle?
Seattle’s city guidance says renters generally cannot operate short-term rentals, except for limited legacy operators in the Downtown Urban Core who meet documentation rules, according to Seattle FAS and Seattle Ordinance 125490.
When does RRIO apply?
A short-term rental that is not in the operator’s primary residence, or a portion of that residence, must be registered and compliant under Seattle’s Rental Registration and Inspection Ordinance, according to Seattle FAS and SDCI guidance.
