Overview: Are Short-Term Rentals Allowed on Lummi Island?

Yes, short-term rentals are allowed on Lummi Island, Washington, but they are subject to Whatcom County regulations and specific zoning requirements. Lummi Island falls under Whatcom County jurisdiction and is zoned as Rural Residential-Island (RR-I) district. Vacation rentals are permitted as accessory uses in most zones, though they face additional restrictions in shoreline areas and the Lake Whatcom Watershed.

How to Start a Short-Term Rental Business on Lummi Island

Step 1: Verify Zoning Compliance

Lummi Island properties must comply with Whatcom County's Rural Residential-Island (RR-I) zoning district regulations. Vacation rental units are considered accessory uses and must adhere to the district's development standards.

Step 3: Lake Whatcom Watershed Considerations

Properties located within the Lake Whatcom Watershed face additional restrictions and may require conditional use permits for vacation rental operations.

Step 4: Municipal Separate Business Licensing

Operators must obtain appropriate business licenses and comply with state tax collection requirements for transient accommodation.
