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

Our review of Lassen County's sources did not turn up any dedicated garage-sale or yard-sale ordinance, permit requirement, fee, or limit on the number of sales per year for the unincorporated area. On that basis, occasional residential yard and garage sales appear to be unregulated by a specific County permit scheme, which is typical for a small rural county. Two general limits still apply. First, the County Code's public-nuisance chapter (Section 1.18.020) treats accumulations of merchandise, trash, junk, and debris that become unsightly or interfere with neighbors as a public nuisance, so leftover goods cannot simply be left out indefinitely after a sale. Second, on-site and off-site signage may be subject to the County's zoning and sign provisions in Title 18 (Zoning); temporary signs placed in the public right-of-way or on utility poles can be removed. Because there is no County-specific permit, residents should treat yard sales as occasional, keep signs off the public right-of-way, and clean up unsold items promptly. This reflects the absence of a found ordinance rather than an affirmative County allowance; anyone planning frequent or commercial-scale sales should confirm current rules with Lassen County Planning and Building Services. These observations apply to the unincorporated area only, not the City of Susanville.
