Washington Airbnb laws: local permission, insurance & taxes

Which Washington state duties apply?

Chapter 64.37 generally addresses paid lodging in a dwelling for fewer than 30 consecutive nights. Its definition excludes an owner-occupied dwelling used by the owner for at least six months in the calendar year when fewer than three rooms are rented at once. That chapter-specific exclusion does not decide local licensing or tax treatment.

• For covered rentals, provide a contact available during the stay and comply with carbon-monoxide alarm requirements.
• Post the address, emergency-service contacts, escape-route floor plan, occupancy limit and operator contact inside the unit.
• Maintain at least $1 million aggregate primary liability coverage, or conduct each transaction through a platform providing equal or greater primary coverage.

Source: RCW 64.37.010, .030 and .050. Ask the insurer to confirm actual coverage, exclusions and direct bookings in writing.

A platform-only insurance route needs special attention when adding a direct-booking website. A covered platform stay does not establish coverage for a separately paid reservation. Keep the policy period and insured address with the channel records.

Seattle: one investment unit is different from two

Seattle’s usual operator limit is one dwelling unit, or two if one is the operator’s primary residence. The units generally must be owned by the operator. Limited legacy exceptions exist; a buyer should obtain a city determination rather than assume an older listing proves an exception.

The owner’s operator license and Seattle business license tax certificate are separate requirements. Keep the operator number in listings and a guest contact in the unit. A property manager does not take over the owner’s licensing obligation.

Seattle approvals, inspections and renewals

Seattle posts a $75 per-unit operator-license fee and a one-year term. Keep the business license tax certificate current before applying for or renewing the regulatory license. These figures exclude other business, inspection, repair and insurance costs.

Source: Seattle licensing and fee instructions. The city’s ADU/DADU fee treatment is specific; ask how it applies before multiplying fees by units.

A dedicated rental that is not your primary residence or a portion of it must also comply with the Rental Registration and Inspection Ordinance (RRIO). The city specifically includes dedicated ADUs in that registration guidance. Complete RRIO registration before listing a non-primary-residence STR.

Build a renewal file with the license expiration, business certificate, primary-residence evidence where applicable and inspection status. Before buying, ask the city what the new owner must obtain and whether any claimed legacy exception survives; do not put the seller’s license number into your new listing without that answer.

Chelan County: match the tier to the calendar

For county-regulated properties, new Tier 2 and Tier 3 applications are accepted June 1–July 31, where the area has capacity. Tier 1 applications are accepted year-round. Confirm the parcel’s tier and jurisdiction before using either calendar.

Check the county STR statistics and cap information before applying. Capacity in another ZIP or growth area does not create capacity for this parcel. Assemble the management plan and parking diagram rather than submitting only a tax number.

Chelan sale and inspection checks

Chelan County says transferability depends on the property’s circumstances. If transfer is allowed, it must be completed within 30 calendar days of closing through county staff. Do not assume a permit listed in a sales brochure will transfer.

The county’s current renewal process requires an in-person Fire Marshal inspection every other year; the other years use a self-inspection checklist. Identify which year applies and obtain the required inspection before renewal issuance.

The City of Chelan is a different program. Its page posts a $600 initial license fee per unit, $300 annual renewal, and a 60-day ownership-transfer window. A city address and an unincorporated county parcel therefore do not share a transfer deadline.

Platform collection does not erase Washington B&O

Washington lodging can involve retail sales tax, local lodging taxes and Retailing business and occupation (B&O) tax. B&O is a business tax on gross receipts, not the same charge as guest sales tax. Use the property’s location and current DOR lodging-rate tables; there is no one all-in Washington rate.

Retailing B&O may still be due after the small-business credit. Marketplace commissions are business costs, not a deduction from gross rental receipts for this purpose.

Sources: DOR marketplace and property-manager guidance; personal-home rental tax instructions. Local business taxes require a separate check.

Reconcile gross receipts before the payout

For each month, retain gross rent, taxable charges, refunds, commission, each tax collected, remitter and payout. Match the tax certificate’s property location to the listing and compare the direct-booking ledger with marketplace statements before filing.

Once the use is permitted, test ordinary and slow-season bookings, owner-use nights, cleaning per turnover, management, insurance and reserves. The single-family calculator can help compare a longer-term rental alternative using that model’s own rent and costs. It does not determine short-term rental eligibility.
