Garage sale signs in Oak Lawn must be placed on private property with owner permission, removed promptly after the sale, and kept out of the public right-of-way. Signs attached to utility poles, street signs, or trees are prohibited and subject to removal.
Oak Lawn permits temporary garage sale signs subject to placement and timing rules. Signs may be placed on the owner's property or on other private property with the owner's express permission. Signs in the public right-of-way (parkway strips, street medians, utility pole attachments, traffic sign posts, trees on public property) are prohibited and may be removed by Public Works or Code Enforcement without notice. Sign size is typically limited to 4-6 square feet for residential temporary signs. Signs must be removed within 24-48 hours after the sale ends. Multiple signs along a route must all comply with placement rules. Attaching signs with nails or staples to utility poles and trees is specifically prohibited and can cause utility worker injuries and tree damage. Violators may face modest fines. Many residents successfully advertise garage sales through free online listings (Facebook Marketplace, Craigslist, Nextdoor) to supplement on-site signage.
Signs in the public right-of-way are removed without notice. Repeat violators may receive fines starting around $25-75 per sign. Signs left up more than 48 hours after the sale may also trigger enforcement.
