Summary
Solano County treats an owner-occupied short-term rental of a single guest room, called a "hosted rental," as a distinct use from a whole-house vacation rental, capping it at one guest room, one guest vehicle, and the operator's own primary residence under Section 28.72.40(B)(5).
5. Hosted Rental
a. A hosted rental shall be restricted to one single-family dwelling, or one single-family dwelling plus a legally established guest house, which is the primary residence of the hosted rental operator. Hosted rentals shall not be permitted in nonhabitable structures or in tents, RVs, or other provisions intended for temporary occupancy. Only one hosted rental is allowed per parcel. A hosted rental may not be located on the same site as a vacation house rental unless a use permit has been obtained for the combined use. A whole-house vacation rental is not a hosted rental, even if the property owner resides in another dwelling unit on the same property.
b. Maximum of one guest room or sleeping area.
c. Limit of one vehicle associated with the transient use.

Full Breakdown
30. A hosted rental is restricted to one single-family dwelling, or that dwelling plus a legally established guest house, that also serves as the primary residence of the operator; it cannot be run out of a nonhabitable structure, tent, RV, or other temporary-occupancy provision, and only one hosted rental is allowed per parcel. The code draws a sharp line against combining uses: a hosted rental may not be located on the same site as a vacation house rental unless a use permit has been obtained for the combined use, and a whole-house vacation rental is never a hosted rental even if the owner lives in a separate unit on the same property.
Subsection (b) caps the use at a single guest room or sleeping area, and (c) limits guest parking to one vehicle associated with the transient use. Food service, if offered, is limited to registered guests and must meet the California Retail Food Code, and subsection (e) bars weddings, lawn parties, or similar events outright. The operator must maintain a functioning septic system or sewer connection under (f), and under (g) the use is subject to transient occupancy tax under Chapter 11, Article II, plus a Chapter 14 business license, with the TOT certificate number and business license number required on every rental contract, advertisement, and website listing.
Violations & Fines
Operating a hosted rental without the required business license and transient occupancy tax registration, exceeding the one-guest-room cap, hosting events, or combining it with a vacation house rental on the same site without a use permit violates Section 28.72.40(B)(5) and is enforceable, per subsection (h), under the same administrative penalty and business-license provisions that apply to Solano County's short-term rental ordinance generally.
