Yellowstone County sets no permit or frequency limit on residential garage sales in the unincorporated county. In Billings, the sale itself needs no permit, but garage-sale signs may not be placed on poles or the right-of-way and a temporary sign permit applies to longer-standing signs.
There is no Yellowstone County ordinance requiring a permit to hold a yard or garage sale in the unincorporated county, nor a set cap on the number of sales per year. In the City of Billings, occasional garage sales are treated as an allowed residential activity, but signage is regulated: garage-sale, yard-sale, moving-sale, and bazaar signs are not allowed on street light poles, traffic-control boxes, sidewalks, or traffic poles, and must be on private property with the owner's permission. One temporary sign is allowed up to 30 days each calendar year, requiring a temporary sign permit from the Planning Division.
County: none specific to garage sales. Billings: illegally placed signs may be removed by the city, and repeated commercial-scale selling can trigger home-occupation zoning review.
