What this means for your move
Most 10-, 12-, and 14-foot-wide portable buildings exceed the 8'6" legal width in Illinois, so a permit is required for nearly any move on public roads. An 8-foot-wide shed usually travels permit-free as long as trailer deck height keeps the total under 13'6".
Plan the route around Chicago alley access and downstate flat farmland. Cook County moves often need municipal as well as state permits. Escort vehicles are billed per mile and are typically the largest add-on cost after the haul itself.
Professional shed haulers usually carry annual blanket permits, which removes the per-trip paperwork for the homeowner entirely.
