Boulder allows temporary garage sale signs with restrictions on size, placement, and duration. Signs in public rights-of-way may be prohibited. Signs must be removed immediately after the sale.
Boulder permits temporary signs advertising garage and yard sales with specific regulations. Signs are typically limited to 4 to 6 square feet. A maximum number of directional signs, usually 3 to 5, may be placed off-premises to guide buyers. Signs must not be attached to utility poles, traffic signs, or public property. Placement in the public right-of-way varies by jurisdiction — some allow it temporarily, others prohibit it. Signs must be posted no earlier than 24 to 48 hours before the sale and removed within 24 hours after. Some cities require a garage sale permit which may include sign allowances. Wire-frame yard signs are the most common format.
Signs on utility poles: removal and fine $25 to $50. Signs not removed after sale: fine $25 per day. Excessive signs: warning, then citation.
