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

Colusa County's Zoning Code does not set a blanket "maximum occupants" figure for every recreational lodging facility. Instead, Section 44-4.100.010(D) uses guestroom count as the dividing line for building-code treatment: a facility with five or fewer guestrooms is considered a single-unit residential dwelling or lodging house, while six or more guestrooms within one structure triggers further requirements under the building code, unless additional standards apply as adopted by the County from time to time. That threshold determines which building-code track a farmstay, bed and breakfast, or outdoor recreation lodging use falls into, and it applies before any specific use-type standard is layered on top.

Farmstays carry the sharpest numeric cap in this chapter: Section 44-4.100.020(B) limits the use to a maximum of four guest rooms for up to eight guests at any one time, with those rooms confined to the primary or secondary dwelling on-site. Bed and breakfast inns, by contrast, may provide up to twelve guestrooms under Section 44-4.100.040(1), so the occupancy ceiling that applies depends on which recreational lodging category the county classifies the operation under, not a single county-wide guest limit.
