City Context

How is Joliet zoned?

Joliet regulates land through 17 zoning districts, and the roster contains something few cities have: a family of three intermodal terminal districts. Coded I-TA, I-TB and I-TC, they cover the terminal itself, transportation equipment, and an intermodal terminal industrial park, together accounting for roughly 3,617 acres.

That is the single most distinctive feature of Joliet's zoning map. The city sits at a major national freight interchange, and rather than folding that into a general industrial district it has written three separate classifications for it, distinguishing the terminal operation from the equipment yards and the associated industrial park.

Industrial more broadly is substantial: light industrial covers roughly 6,728 acres, the second largest district in the city, and general industrial about 3,549. Adding the intermodal districts, industry accounts for well over thirteen thousand acres.

The residential system is a lettered and numbered series. Single Family Residential appears as R-1, R-1A, R-1B, R-2 and R-2A, with R-2 the largest district in the city at roughly 9,804 acres and R-1B second among residential at about 5,711. Multifamily runs low and high density, and a one and two family district sits between.

Business runs neighborhood, central and general, with a restricted business district at roughly 424 acres. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
