Castle Rock does not require a permit for a residential garage sale, but sign placement is strictly regulated. Signs, including garage-sale signs, may not be placed in the public right-of-way at any time, and property maintenance standards still apply during and after the sale.
The Town has no garage-sale license requirement for occasional residential sales, but signage is controlled under the sign code. The Town states that placement of signs in the public right-of-way "is prohibited at all times," and this expressly includes temporary garage-sale signs. Signs may generally be posted only on the private property where the sale occurs. Merchandise and any leftover trash must not accumulate or block sidewalks, which "must remain free from obstructions." A temporary sign permit is available through the Zoning Division for other display situations; contact 720-733-3557 for details.
Signs placed in the right-of-way may be removed by the Town, and code compliance may cite unabated debris left after a sale under the property-maintenance standards.
