Watkins CDP (part), Arapahoe County, Colorado Property Maintenance: Garage Sale Rules Rules (2026)

Property maintenance codes apply to garage sales across Arapahoe County. Aurora City Code §46-300 (property maintenance) and Centennial Municipal Code §7-6 (nuisance) require that merchandise displayed during garage sales be organized on tables, racks, or in clearly defined display areas—not scattered loose across the yard. At the end of sale hours each day, all items, tables, and displays must be removed from public view (brought into garage, shed, or stored behind fencing). Between sale days and after the final day, nothing can remain at the curb or in the front yard. Unsold items left at the curb for donation pickup or future reuse convert the property to a blight condition triggering code enforcement. Signs advertising the sale must be removed within 24 hours of the sale ending per Aurora §94-280 and Centennial §12-11. Off-premise signs in the public right-of-way are generally prohibited even during active sale days. Properties with patterns of ongoing visible clutter, regardless of whether from garage sales or other causes, face escalating blight citations. HOAs typically enforce even stricter post-sale cleanup requirements.
