Overview (Investor Takeaway)

• Are STRs allowed in Mount Vernon, WA? Yes—Washington State allows short‑term rentals. The City of Mount Vernon does not prohibit STRs. However, STRs are subject to the property’s zoning (confirm allowed use and any conditions with Development Services) and you must obtain a City business license. Washington State also imposes specific STR safety, posting, and insurance requirements, as well as state business registration and state/local tax obligations.

Important note: The City’s STR page does not provide a comprehensive local ordinance or fee schedule. Treat the guidance below as a compliance baseline and verify specifics with the City’s Development Services and Finance Departments prior to listing.

How to Start a Short-Term Rental Business in Mount Vernon, WA

  • Call Development Services at 360-336-6214 to verify whether your property’s zoning permits lodging uses and whether any conditions (parking, occupancy limits, etc.) apply.
• Obtain a City business license
  • The City requires all businesses within city limits to obtain a City business license, issued by the Finance Department. License applications are handled through the statewide Business Licensing Service (BLS).
• Register your business with Washington State (UBI)
  • If you will collect sales tax or expect gross income at or above $12,000 per year, register through the Washington Department of Revenue (DOR) to obtain a Unified Business Identifier (UBI). Most STR operators exceed the $12,000 threshold.
