Mono County, CA Property Maintenance: Garage Sale Rules (2026)

Unincorporated Mono County does not, in the sources reviewed, publish a specific garage-sale or yard-sale ordinance setting a permit requirement, a maximum number of sales per year, or detailed sign rules. In practice this means residents of unincorporated communities can typically hold occasional yard and garage sales without applying for a county permit. That said, two general categories of County rule still govern related conduct. First, signage placed in the public right-of-way or on county roads is subject to general sign and encroachment standards, and temporary directional signs should not obstruct sightlines or create a traffic hazard; sale signs should be removed promptly after the event. Second, the County's nuisance and solid-waste framework applies to what happens after the sale: unsold goods, boxes, and debris cannot be allowed to accumulate in a way that creates a public nuisance, and disposal must go through proper channels, namely self-haul to one of the County's six transfer stations (where glass, plastic, aluminum, cardboard, batteries, used oil, and household hazardous waste are accepted free) or a subscribed franchise hauler. Because no exact code section governing garage sales was located, no permit fee, sale-count limit, or specific penalty is asserted here. Residents in homeowner-association areas should also check private CC&Rs, which can impose stricter limits than the County.
