Overview: Are Short-Term Rentals Allowed in Whitethorn, CA?

YES — Short-term rentals are now permitted in Whitethorn, CA, which is located in unincorporated Humboldt County. This represents a significant change, as short-term rentals were previously illegal except in specific areas like the inland portion of Shelter Cove. The Humboldt County Board of Supervisors adopted the Short-Term Rental Ordinance on March 5, 2024, creating a comprehensive permitting framework that applies to Whitethorn and all unincorporated areas of the county.

The ordinance balances tourism and economic development with housing stock protection and neighborhood quality preservation. Both inland and coastal versions are now effective, providing investors with a clear pathway to operate legitimate short-term rental businesses in Whitethorn.
