Denver allows temporary garage sale signs on private property only. Signs in public right-of-way, on utility poles, or on traffic control devices are illegal under DRMC §49-247 and removed on sight.
Denver Revised Municipal Code §49-247 prohibits attaching any sign, poster, or placard to any tree, pole, lamppost, curbstone, sidewalk, or public structure in the public right-of-way. Garage sale signs must be placed entirely on private property with the owner's permission. The Denver Zoning Code limits temporary residential signs to 6 square feet per sign. Signs should go up no more than 48 hours before the sale and come down within 24 hours after. Denver Public Works and the Right-of-Way Enforcement team actively remove illegally posted signs, especially along major arterials. No garage sale permit is required for occasional residential sales, but sales held more than 3 times per year may trigger home occupation licensing.
Signs on poles/public property: removed on sight, $50 to $150 fine per DRMC §49-247. Repeat posting: escalating fines. Signs left up after sale: code enforcement citation.
