Idaho Falls, ID Property Maintenance: Garage Sale Rules (2026)

The City of Idaho Falls addresses residential garage and yard sales primarily as a Code Enforcement matter to keep neighborhoods from being used for ongoing outdoor retail. According to the City's official FAQ, garage sales are limited to two (2) every 12 months for a calendar year, and any single sale is to be no more than three (3) days in duration. The concern the City highlights is sale merchandise being left out on display in a yard between sales, which can be addressed as a violation. The City has not published a specific numbered ordinance section for garage-sale frequency in the materials reviewed, so residents with questions about a particular situation should contact Idaho Falls Code Enforcement. Separately, anyone posting garage-sale signs should be aware of City Code Section 5-8-8, which prohibits affixing handbills to public utility poles, sign posts, lamp posts, telephone poles, shade trees, or public structures, and Section 5-8-9, which bars posting signs on another person's property without the owner's or occupant's consent. Leftover items that become an accumulation of refuse or junk after a sale could also fall under the litter-accumulation rules of Section 5-8-10. These limits are aimed at distinguishing genuine occasional household sales from a de facto unlicensed business operating out of a residence.
