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

Yes, short-term rentals are allowed in Rio-Dell, CA, but they are strictly regulated. Rio-Dell falls within Humboldt County's jurisdiction as an unincorporated community. The Humboldt County Board of Supervisors approved a comprehensive Short-Term Rental Ordinance on March 5, 2024, which specifically includes Rio-Dell in the "Greater Humboldt Bay Area Short-Term Rental Cap Area." This designation subjects STR operations in Rio-Dell to the most restrictive regulations in the county, including a strict 2% cap on the total housing stock that can be used for short-term rentals.

How to Start a Short-Term Rental Business in Rio-Dell

Step 1: Confirm Eligibility

• Ensure your property is not subject to any recorded restrictions that prohibit short-term rentals
• Verify your dwelling unit is legally permitted or legal nonconforming
• Check that your property is not:
  • Located on a lot approved under SB 9 (California H.O.M.E. Act)
  • An Accessory Dwelling Unit permitted after January 1, 2020
  • An Alternative Owner Builder dwelling (unless it can be permitted after-the-fact)
  • Subject to active code violations

Step 2: Understand the Application Timeline

• Existing Operators: Applications will be accepted starting April 2024 (when the ordinance takes effect), with priority given to operators who can demonstrate income from STR operations prior to October 26, 2023, and who have no unresolved property violations
• New Operators: Can apply after the initial 60-day period for existing operators, subject to cap availability
• Important: No permits will be issued during the first two months following the ordinance's effective date, but applications will be received

Step 3: Determine Permit Type

Important Note for Investors: This ordinance represents a significant shift in Humboldt County's approach to short-term rentals. The 2% cap in the Greater Humboldt Bay Area (including Rio-Dell) is among the most restrictive in California. Given the limited number of available permits and the priority given to existing operators, new investors should act quickly but thoroughly to secure permits. The regulation emphasizes neighborhood compatibility and housing preservation, so properties that can demonstrate minimal impact on surrounding residential character will have the best chance of approval.
