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

A review of the Mendocino County Code finds no chapter that specifically licenses, permits, or limits residential garage, yard, or rummage sales in the unincorporated County. The Business Licenses title (Title 6) covers business licenses, film permits, timber operations, outdoor festivals, tobacco retailers, and cannabis, but contains no garage- or yard-sale provision. This means there is no county frequency cap, sign-permit requirement, or per-sale fee in the code for occasional household sales. Residents should still observe general rules that can apply: the County's zoning ordinance (Title 20) regulates home occupations and limits commercial activity in residential zones, so a continuous retail operation run as a 'garage sale' could be treated as an unpermitted business; temporary signs are subject to the County sign regulations; and merchandise or unsold goods left accumulating outdoors can become a nuisance under Chapter 8.75 or a fire-hazard rubbish issue under Chapter 8.77. Under California law, anyone making more than two sales of taxable goods in a 12-month period may need a seller's permit from the California Department of Tax and Fee Administration. Because rules differ inside the incorporated cities (Ukiah, Fort Bragg, Willits, Point Arena), this guidance covers only unincorporated areas.
