Summary
Tuolumne County's short-term rental ordinance (Chapter 8.70) is a fire-and-life-safety inspection program and does not set a specific guest occupancy cap. Practical occupancy is governed by the dwelling's safe configuration, including smoke and carbon monoxide alarms in each sleeping area, the posted evacuation plan, septic capacity, and California building and fire code standards.
29] ( Chapter 2 added by Stats. 1961, Ch. 1844. ) 17920.3. Any building or portion thereof, regardless of zoning designation or approved uses of the building, including any dwelling unit, guestroom or suite of rooms, or the premises on which the same is located, in which there exists any of the following listed conditions to an extent that endangers the life, limb, health, property, safety, or welfare of the occupants of the building, nearby residents, or the public shall be deemed and hereby is declared to be a substandard building: (a) Inadequate sanitation shall include, but not be limited to, the following: (1) Lack of, or improper water closet, lavatory, or bathtub or shower in a dwelling unit.
Full Breakdown
70 do not appear to impose a numeric per-guest occupancy limit. 70 is structured as a Fire and Life Safety Inspection program: it requires each rental to have working smoke alarms in every bedroom and at least one per level, carbon monoxide alarms where fuel-fired appliances or fireplaces exist, fire extinguishers, address identification, defensible space, and a posted local-contact and evacuation plan. In practice, the safe occupancy of a particular short-term rental is therefore determined by the number of legal sleeping rooms and exits, the alarm coverage, the on-site septic system capacity for properties not on public sewer, and the occupant-load and egress provisions of the California Building Code and California Fire Code as adopted by the County.
Operators in private communities such as Pine Mountain Lake may also face occupancy and conduct limits imposed by the homeowners association's CC&Rs and STR permit policy, which are private rules layered on top of the County program. Because the County program does not publish a single countywide guest-count formula, operators should size occupancy to the home's legal bedrooms, egress, and septic capacity and confirm any HOA limits.
Violations & Fines
Because Chapter 8.70 does not set a fixed guest-count cap, the County's enforceable occupancy-related requirements are the safety conditions verified at inspection: adequate smoke and carbon monoxide alarms, fire extinguishers, posted evacuation information, and defensible space. A rental that cannot meet these conditions, or that converts non-sleeping spaces such as garages into unpermitted bedrooms to increase headcount, can fail the Fire and Life Safety Inspection and be barred from operating until corrected. Exceeding the occupant load or egress limits of the California Building and Fire Codes, or violating a homeowners association occupancy limit in communities like Pine Mountain Lake, is separately enforceable.
