Snohomish County, WA Airbnb & Short-Term Rental Regulations 2026

Regulation Overview

A large, varied county running from Everett and the Seattle commuter belt out to Stevens Pass and the Cascades, with demand split between business travel and mountain recreation.

Washington sets a statewide floor for short-term rentals but lets counties and cities go much further, and they do. Local position here: County STR permit in unincorporated areas.

Washington State Law (RCW 64.37)

Washington regulates short-term rentals statewide through Chapter 64.37 RCW. Unlike Arizona or Texas, this is a floor, not a ceiling: the statute sets minimum obligations, and it does not preempt counties and cities from regulating far more heavily on top. That is why the spread between Washington markets is so wide.

What the statute defines and requires:

• Definition. A short-term rental is a dwelling unit offered to a guest for a fee for fewer than 30 consecutive nights.
• Liability insurance. An operator must carry primary liability insurance covering the unit of at least $1,000,000 in the aggregate, or conduct every transaction through a platform providing equal or greater primary coverage. Note this is double Arizona’s minimum.
• Taxes. Operators must remit all applicable local, state and federal taxes — occupancy, sales, lodging and any other fee or assessment a hotel or bed and breakfast in the same jurisdiction would pay — unless the platform does it for them.
• Guest contact. Operators must give guests contact information, available during the stay, for someone who can respond to issues at the property.
• Carbon monoxide alarms. Operators must confirm the unit complies with carbon monoxide alarm requirements.
• Platform registration. A short-term rental platform may not operate in Washington unless it complies with the chapter and registers with the department.

No State Preemption — why local rules decide everything

This is the single most important structural fact about investing in Washington short-term rentals, and it is the opposite of states like Arizona:

Washington counties and cities may cap short-term rentals, and may prohibit them in specific areas. Nothing in RCW 64.37 stops them. The practical results across this state include hard numeric caps tied to housing stock, once-a-year application windows, conditional use permitting, and outright geographic exclusion zones.

Two consequences for a buyer:

• The permit can be worth more than the finish level. In capped jurisdictions, whether a property can legally operate — and whether that right survives a sale — matters more than any renovation.
• Jurisdiction is the first question, not a detail. Unincorporated county, incorporated city and urban growth area can each carry different rules within a few miles. Establish which one the parcel sits in before anything else.

Snohomish County Rules

Snohomish County splits cleanly between unincorporated county and the incorporated cities, and the requirements are different on each side of that line.

• Unincorporated Snohomish County: property owners must apply for a short-term rental permit through the county’s Planning and Development Services department.
• City of Snohomish: short-term rentals are allowed under Municipal Code 14.207.070 in any zone where dwelling units are allowed — single-family, multi-family, commercial, historic business district, business park and midtown. The city does not require a short-term rental specific permit, but you do need a City of Snohomish business licence.

Other incorporated cities in the county set their own rules, so the first question on any Snohomish County property is which jurisdiction it actually sits in.

Lodging Taxes & Licensing

Washington short-term stays carry a stack of lodging taxes: state and local sales tax, local lodging or transient occupancy taxes, and in some jurisdictions tourism promotion area charges. Combined rates commonly land in the region of 10% or more, varying by location.

Airbnb and Vrbo collect and remit some of these on your behalf, and RCW 64.37 relieves the operator of remitting where the platform does it. That relief is specific to what the platform actually collects — it is not a blanket exemption, and direct bookings are entirely your responsibility. Most operators also need a Washington State business licence and a UBI number.

Rates change and vary by jurisdiction, so we do not publish a single combined figure here. Confirm the current rate for your exact address with the Washington State Department of Revenue and the local jurisdiction before you model net income.

Buyer Due Diligence Checklist

Washington rewards address-level diligence more than almost any state on this site. Before you write an offer:

• Establish the jurisdiction. Unincorporated county, city limits or urban growth area — each may have a different rulebook.
• Ask whether a cap exists, and where it currently stands. A cap that is already exceeded means no realistic path to a permit.
• Ask whether an existing permit transfers on sale. In some Washington jurisdictions it does not, and a listing marketed as a running short-term rental may convey nothing of the sort.
• Check for geographic exclusions — watershed, shoreline and overlay zones can prohibit the use outright at parcel level.
• Check septic capacity where the property is not on sewer. It can cap occupancy below bedroom count, and therefore cap revenue.
• Get it in writing from the planning department for the specific parcel. A verbal from anyone else is not diligence.
