Plum Farms Data Center Proposal

Operator not disclosed. Withdrawn.

A developer sought to rezone the 186 acre Plum Farms property at Higgins Road and Route 59 in Hoffman Estates to manufacturing use for a possible data center. The site sits on the edge of the village, bordering South Barrington and Barrington Hills, and drew weeks of organized neighbor opposition. The developer withdrew its rezoning request on July 1, 2026 after state lawmakers failed to pass data center regulation and Governor Pritzker paused state incentives.
