Jefferson County has no separate garage-sale ordinance or permit for occasional residential yard sales in unincorporated areas; they are a customary accessory residential use. Sales that become ongoing or commercial in scale can trigger zoning and special-event rules. Incorporated cities may require permits.
The unincorporated county's Zoning Resolution does not set a specific number of garage sales per year or require a garage-sale permit; occasional personal-property sales at a residence are treated as an accessory use rather than a business. Frequent or large sales that amount to a retail/commercial use are not a permitted home use and would need proper zoning; larger gatherings fall under the Zoning Resolution's Special Events provisions. Signs in the public right-of-way are separately restricted. Check with individual cities (Arvada, Lakewood, Wheat Ridge, Golden) as several regulate frequency or require a permit.
Running a de-facto ongoing retail operation from a home can be cited as a zoning violation, starting with a notice and 10-day correction period before a summons and complaint. Illegally placed signs may be removed.
