Will County allows temporary garage sale signs on private property with owner consent. Signs limited to 4-6 sq ft, off-site directional signs typically 3-4 maximum. ROW placement on utility poles and traffic signs prohibited. Removal required within 24 hours of sale end.
Garage sale signs are regulated as temporary signs under Will County Land Use Ordinance §155-14.300 and parallel municipal codes. Typical rules: on-premises sign limited to 4-6 sq ft, no illumination, posted no earlier than 48 hours before the sale. Off-premises directional signs limited to 3-4 total, placed only on private property with the owner's permission. Placement on utility poles, traffic signs, light posts, or in the public right-of-way is prohibited — Illinois Commerce Commission rules and municipal codes authorize removal without notice. In Bolingbrook, Romeoville, and Plainfield, a garage sale permit may be required (typically free or $5) limiting sales to 2-3 per year per residence for 3 consecutive days. Frankfort and New Lenox allow sales without permits but enforce sign rules. Signs must be removed within 24 hours of the sale ending; homeowner is liable even if buyers post additional signs. After summer tornado and severe-weather events, garage/moving sales spike and enforcement sweeps are common across Will County.
Signs on utility poles or ROW: removed by municipality, fine $25-$100. Oversized signs: warning then $25-$75 citation. Signs not removed post-sale: $25 per day under most municipal codes. Unpermitted sales in Bolingbrook/Romeoville: $75-$250.
