Grass Valley, CA Short-Term Rentals: Occupancy Limits (2026)

Many California resort jurisdictions set a maximum occupancy for short-term rentals, often expressed as two guests per bedroom plus two, or a hard cap per property. Unincorporated Nevada County does not have such a rule, because it has not adopted a dedicated short-term rental ordinance. The County's Short-Term Rental FAQs state that the County does not have restrictions on renting out rooms within private residences or on renting out primary residences on a short-term basis, and that no Planning Department permit is required. As a result, there is no STR-specific occupancy formula in the unincorporated county. In the absence of an STR ordinance, the practical limits on occupancy come from generally applicable requirements: the structure must be permitted for residential use through the Building Department, and any use must comply with the California Building Code, fire and life-safety provisions, and septic or wastewater capacity for the dwelling. Operators should confirm that the legal number of bedrooms and the septic system rating support the number of guests they intend to host. This contrasts sharply with the incorporated cities and the Town of Truckee, which set explicit STR occupancy caps in their own permit programs. Operators near those boundaries should verify which jurisdiction governs their parcel before advertising a maximum guest count.
