Primary-Residence-Only Rule
Shasta County does not require a vacation rental to be the owner's primary residence. Under Section 17.88.230 a vacation rental is a whole one-family residence rented for 30 days or less, and the owner 'may or may not' live on the parcel. Hosted homestays differ: the owner must reside in the home. Accessory dwelling units may never be short-term rentals.
