Run the Seattle verdict on your facts
| What counts as a short-term rental | Seattle licenses STR operators (not just units): an operator may run their primary residence plus ONE additional unit — a two-unit lifetime cap per operator — under an STR operator license on top of the city's rental-registration system. |
|---|---|
| Permit / license | STR Operator License (plus RRIO rental registration where it applies) — issued by Seattle Department of Construction & Inspections |
| Fee | Operator license about $75 per unit |
| Renewal | Annual renewal |
| Primary-residence rule | One of your (max two) units must be your primary residence; a narrow legacy exception covers some pre-2019 downtown operators. |
| Whole-home rental | Whole-home rentals allowed for the primary residence + one additional unit, per operator. |
| Night cap | — |
| Guests / occupancy | Per building/fire codes |
| Minimum stay | Under 30 days defines the regime |
| Zoning | The operator cap is the zoning fact: portfolios beyond 2 units are not licensable in Seattle. |
| Density / scarcity | No density cap found in the current rules |
| Fines | Unlicensed operation draws per-day penalties under the municipal schedule and license ineligibility |
| Taxes | State sales tax + Seattle lodging taxes; the license and tax accounts are separate. |
| Platform duties | Platforms must verify operator licenses and share data with the city (Seattle's platform rules are among the oldest). |
| State layer | No state preemption, plus a state insurance/safety layer (RCW 64.37). Seattle licenses operators with a two-unit cap; several counties license by zone. |
What trips hosts in Seattle
- Seattle licenses the OPERATOR, not the property — the cap follows the person across addresses.
- Renters: you may license your own primary residence as an operator if your lease allows it — the lease question comes first, as always.
The private layer still applies
These are the city's rules. Your HOA, condo board, lease or mortgage can say no on top of them — that layer is printed as a warning in the checker, never merged into the city's verdict.
