Full Breakdown
645's public-property rules. 006(C) exempts garage sale signs placed in the public right-of-way from a separate permit, but requires that they be displayed only on "weekends, legal holidays and broker tour days" and removed at the conclusion of the event; hold to the same three-by-three-foot maximum dimensions including any stake or pole; and be placed "in locations where they will not interfere with normal pedestrian or vehicle traffic," never in a street median, on a light standard or pole, or blocking the view of another sign.
That section confirms the four-sign cap applies "for each event or message," allows unattended placement, and bars illumination. 006(C)(6), meaning code enforcement or public works crews can pull down an out-of-time garage sale sign without prior notice.
Violations & Fines
Signs displayed outside weekends and legal holidays, exceeding the 3-by-3-foot size cap, or exceeding the one on-site/four off-site count may be summarily removed by the city under Section 17.645.006(C)(6). Beyond removal, any violation of the sign chapter is a nuisance per se under Section 17.640.010, with each day of noncompliance a separate offense subject to abatement.
