Full Breakdown
Jackson County's Unified Development Code exempts temporary garage-sale signs from its off-premise sign permit requirement in any zoning district, but only within limits: no more than 90 days of placement per calendar year, written permission from the private property owner where it's posted, a 20-square-foot maximum face area, and no more than two temporary signs during the year. Permanent or larger signs need a permit from the Director. This applies only to unincorporated Jackson County. Kansas City, Independence, Lee's Summit, Blue Springs, Raytown and Grandview each enforce their own municipal sign codes.
Violations & Fines
Signs exceeding the 90-day, 20-square-foot, or two-sign limits lose the exemption and require an off-premise sign permit from the Director before placement; unpermitted noncompliant signs can be ordered removed.
