What drives fence cost in Illinois

Illinois pricing is a tale of two markets: Chicagoland labor and permitting push costs well above downstate, and the blended figure lands about 13 percent over the national average. The 40-inch frost line makes for deep post holes in heavy clay that holds water — belled footings and crowned concrete pay off. Wind off the open prairie stresses long privacy runs. Chicago and many suburbs require permits with plat-of-survey documentation, so paperwork lead time is real.
