Mono County, CA Short-Term Rentals: Noise Rules (2026)

The County's transient rental standards (General Plan Land Use Element Chapter 26) are designed to prevent transient rentals from disturbing the peace and quiet of residential neighborhoods. Rather than fixing a numeric decibel limit or stated quiet hours within the transient rental standards themselves, the County relies on a combination of disclosure, a responsive local manager, and general nuisance enforcement. Chapter 26 requires interior posting of key information, including the property address, emergency contacts (911, the property manager, and the sheriff/fire), trash-disposal instructions, and the consequences for violations, so guests know how to behave and who to call. A designated property manager or management company must be available on a 24-hour basis to address problems, including noise and other disturbances, and the owner must also be personally available by telephone on a 24-hour basis (failure to remain reachable can be grounds for permit revocation). General loud or unruly conduct that disturbs neighbors can be addressed as a nuisance and through the Sheriff's Office. Because amplified-sound and quiet-hour specifics may be addressed in separate noise provisions or permit conditions rather than the transient rental standards, operators should confirm any applicable quiet-hours or decibel requirements (and current permit conditions under MCC Chapter 5.65) with the County.
