Twain Harte, CA Property Maintenance: Garage Sale Rules (2026)

Research of the Tuolumne County Ordinance Code and County website did not locate a specific garage-sale or yard-sale permit chapter for the unincorporated area, so no county-specific permit fee, frequency cap, or sale-hour rule could be verified from a primary source. Occasional household yard sales of personal property are typically viewed as an incidental residential activity rather than a business. What the County does regulate is the line between a casual sale and a business: the Tuolumne County Zoning Ordinance (Title 17) allows "home occupations" only when conducted entirely within a dwelling or private garage by the inhabitants, incidental to the residential use, with no outdoor storage and no employees coming to the site. A continuous or commercial-scale operation run as outdoor retail would exceed those limits and could be cited as a zoning violation. Temporary signs, traffic, and any accumulation of unsold goods are also subject to general Code Compliance enforcement under Chapter 1.10 - which covers sign violations within the road right-of-way and accumulation of garbage, refuse and rubbish. Because rules can change and no standalone ordinance was confirmed, residents planning frequent or large sales should contact the Community Development Department / Code Compliance at (209) 533-6511 before advertising. Do not assume a permit is or isn't required without checking, as this guidance reflects the absence of a located county-specific sale ordinance, not an affirmative exemption.
