Lake County, CA Short-Term Rentals: Primary-Residence-Only Rule (2026)

Many California cities and counties cap or condition short-term rentals based on whether the property is the owner's primary residence, often to protect long-term housing supply. Unincorporated Lake County has not adopted such a rule, because it has no dedicated short-term rental ordinance at all. Nothing in the County Zoning Ordinance's Article 27 use tables conditions transient lodging on owner-occupancy or primary-residence status for a vacation rental. The closest the code comes to an owner-presence concept is in the Bed and Breakfast framework, which treats the use as accessory to a residence, but even there the ordinance does not impose a primary-residence test of the kind seen in dedicated STR programs. As a result, a non-owner-occupied second home or investment property near Clear Lake, Kelseyville, Cobb, or Hidden Valley Lake is not barred from short-term renting by any County primary-residence requirement. The operator must still register for and pay Transient Occupancy Tax under Chapter 18, Article II, and must comply with the underlying zoning and any building and environmental-health rules. Owners should verify current County policy with Lake County Community Development before relying on the absence of an owner-occupancy rule, especially given that the County has been increasing TOT-compliance efforts.
