Full Breakdown
3, part of the Temporary and Portable Signs subsection of the city's sign chapter. No permit is required, which sets garage sale signs apart from most other temporary signage in Renton's code, including real estate directional signs and A-frame business signs that do require a permit. The display window is tightly bounded: signs may go up no more than 24 hours before the sale starts and must come down within 24 hours after it ends, so a weekend sale cannot be advertised for a full week beforehand.
Only nonilluminated freestanding signs or A-frame signs qualify, and each is limited to 32 inches wide by 36 inches tall, matching the size cap Renton also applies to A-frame business signs. Placement rules require signs to sit at least four feet back from the edge of a public roadway and to avoid blocking the sightlines or walking path of drivers and pedestrians. The code separately bars attaching any garage sale sign to a utility pole, a traffic control device, or any other public structure, a restriction enforced against illegal sign placement citywide.
Height is capped at 10 feet measured from finished grade, the same ceiling used for real estate and A-frame signage elsewhere in the chapter. U apply equally to them.
Violations & Fines
Signs left up outside the 24-hour windows, oversized signs, or signs affixed to utility poles or traffic devices are treated as unauthorized signage under RMC 4-4-100.T2: the Building Official may remove them from the right-of-way without notice and store them at the City garage for up to 30 days, redeemable for a minimum $20 fee before the City destroys unclaimed signs. RMC 4-4-100.U makes chapter violations misdemeanors under RMC 1-3-1.
