Aurora, Centennial, and most Arapahoe County cities do NOT require permits for residential garage sales if within frequency and signage limits. No permit needed in unincorporated county. Sales must be personal property only—not commercially purchased inventory. HOAs may impose additional rules.
Garage and yard sales in most Arapahoe County jurisdictions are permit-exempt for residential homeowners within frequency limits. Aurora City Code §46-451 does not require a permit for residential garage sales but limits frequency to 3 per calendar year, each no longer than 3 consecutive days. Centennial Municipal Code does not require permits for homeowner garage sales held within frequency limits (typically 3-4 per year). Littleton, Englewood, Greenwood Village, and unincorporated Arapahoe County similarly allow permit-free sales subject to frequency and signage rules. Sales must be limited to personal property; reselling new or commercially purchased merchandise converts the activity into an unlicensed retail business subject to home occupation zoning violations under Aurora UDO §146-5 and a sales tax license requirement. Signs are generally allowed on the property where the sale occurs but must comply with local sign codes (Aurora §94-280 prohibits off-premise signs in most ROW locations). HOAs in Aurora master-planned communities, Centennial subdivisions, and Cherry Hills Village often have additional CC&R restrictions on garage sale frequency and signage placement.
Operating as unlicensed retail: $100 to $500 Aurora home occupation violation. Exceeding frequency: $50 to $200. Sign violations: $25 to $100. HOA violations: $25 to $100/day per CC&Rs.
