Unincorporated Island County does not currently have a dedicated short-term rental permit system, though new regulations are actively being developed as of 2024. Hosts must comply with existing land-use standards for bed and breakfasts/home occupations and must ensure their septic systems are rated for the intended occupancy levels.
To host an Airbnb in unincorporated Island County (outside city limits like Oak Harbor or Langley), you don't currently need a specific 'STR permit,' but you do need a Washington State Business License. Because most of the county relies on septic systems, the Health Department strictly limits how many people can stay in your home based on your septic's capacity. Be aware that the County is currently writing new laws specifically for Airbnbs, so you should check their 'Short-Term Rental' project page frequently for updates.
