Mono County, CA Short-Term Rentals: Permit Requirements (2026)

Short-term rentals (also called transient or vacation rentals) in unincorporated Mono County are renting a residence for 30 days or less. On December 9, 2025, the Mono County Board of Supervisors adopted a major overhaul of the County's STR rules through General Plan Amendment (GPA) 25-01 and modifications to Mono County Code (MCC) Chapter 5.65, following a 2024 housing study and roughly two years of public input. Under the new framework, an STR in any land use designation generally requires two discretionary land-use approvals — a Use Permit and a separate Short-Term Rental Activity Permit — in addition to two ministerial approvals: a Mono County business license and a Transient Occupancy Tax (TOT) certificate. The County notes that most of the unincorporated county's STRs are concentrated in June Lake (around 90 of roughly 106 permitted units as of the 2024 study), with smaller numbers in areas such as Crowley Lake, Bridgeport, the Mono Basin, and Antelope Valley. STRs are prohibited in certain neighborhoods (for example Mono City and Swall Meadows) and in Multi-Family Residential-Low and -Moderate designations. This is the Mono County (unincorporated) program and does not cover the Town of Mammoth Lakes, which has its own separate rules. Note: the new ordinance is recent, so applicants should confirm current procedures and forms directly with the Community Development Department.
