Amador County, CA Short-Term Rentals: Night Caps (2026)

Unincorporated Amador County imposes no annual-night cap limiting how many nights per year a property may be rented short-term, and no density or saturation cap on the number of rentals in a neighborhood. This follows directly from the County not having adopted a dedicated short-term-rental ordinance; the Planning Commission drafted STR regulations in 2019 and the Board indicated in 2023 it might revisit the topic, but no comprehensive ordinance establishing operating-night ceilings had been adopted for the unincorporated area. The only night-related threshold that matters countywide is the 30-day line in the Transient Occupancy Tax: under Code Chapter 3.16, a stay of 30 days or fewer is a taxable transient occupancy subject to the 10% TOT, while longer tenancies fall outside the transient tax. That threshold determines when the tax applies, not how many nights a host may operate over a year. Where a property operates under a bed-and-breakfast or events use permit, the Planning Commission can attach conditions such as the number of events per year and the days and hours of operation under Code Chapter 19.48, which can effectively limit certain high-impact activity - but those are case-by-case permit conditions, not a countywide annual night cap. Operators should verify with Amador County Planning whether any night-cap or density rule has since been adopted, particularly if the County revisits a standalone STR ordinance, and should confirm any event-frequency limits written into their use permit.
