San Ramon, CA Short-Term Rentals: Extended Home Share (2026)

Section D4-27.D.12 provides: "The renting of un-hosted short-term rentals shall be limited to a maximum of 12 weeks per year. Hosted short-term rentals, with onsite live-in Operators, are not subject to specific limitations on the renting of rooms, etc." A hosted short-term rental is defined in D4-27.A as "the renting of a room or portion in a dwelling in which the Operator is living onsite and actively managing the activities that occur on the property." Because the code exempts that category from the 12-week cap, a resident owner registered as a hosted operator under D4-27.C can rent a room or rooms continuously through the year, subject to the same registration, occupancy (two adults per bedroom under D4-27.D.1), and Terms of Use requirements that apply to every short-term rental, including insurance proof, a 24-hour local contact, and the ban on renting for weddings or other special events under D4-27.D.2.

The exemption is tied strictly to the Operator's onsite presence during the rental; if the Operator is not actually living at the property and managing it during a stay, the rental reverts to the un-hosted definition in D4-27.A and falls under the 12-week limit instead. Registration must still be renewed annually under D4-27.F, and the Director can add site-specific conditions to any registration, hosted or not, under D4-27.E, appealable to the Planning Commission.
