Adams County does not publish a specific occasional garage-sale permit or day-limit for unincorporated homes. Sales must not create blight, block the right-of-way, or violate the county's temporary-sign and trash-container rules. Check with your city if you live inside one.
There is no dedicated garage-sale ordinance for unincorporated Adams County, so residents are not required to obtain a special sale permit for an occasional yard sale at home. However, general standards still apply: leftover merchandise and debris must be cleaned up promptly to avoid an environmental-blight case; temporary sale signs must follow the county's sign rules (and be removed after the sale); and sales must not obstruct streets, sidewalks or the public right-of-way. A recurring or ongoing sale can cross into an unpermitted home business or commercial use. Incorporated cities within the county (such as Brighton, Thornton or Commerce City) often do regulate garage sales, so check your city if applicable.
No sale-specific fine, but leftover items or debris can trigger a blight citation, and off-site or unremoved temporary signs can be removed by the county. Ongoing sales may be treated as an unpermitted commercial use.
