Glenn County, CA Short-Term Rentals: Occupancy Limits (2026)

Unincorporated Glenn County sets no guest-count or per-bedroom occupancy formula specifically for short-term or vacation rentals, since it has not adopted an STR ordinance. The relevant numeric limit in the Title 15 Unified Development Code applies to the bed-and-breakfast establishment use, which the code defines as a single-family dwelling containing no more than four guestrooms used, let, or hired out for transient occupancy of one or more guests. That four-guestroom ceiling is a definitional cap on the B&B use, not a guest headcount for ordinary STRs. For whole-home rentals that are not classified as B&Bs, occupancy is constrained instead by general standards: the California Building and Residential Codes (bedroom and egress requirements), septic-system capacity and well/water limits common to rural parcels, and the county's nuisance authority where overcrowding creates noise, parking, or sanitation problems. Anyone planning a rental should confirm with Planning & Community Development Services how the use is classified and whether the four-guestroom B&B standard or a conditional use permit condition would apply. Septic capacity in particular often becomes the practical occupancy limit on unsewered rural lots.
