Allstate wants back in. The insurance giant is asking South Barrington to re‑annex the 67‑acre parcel that once held its corporate campus just north of the Jane Addams Memorial Tollway, a move that could finally end more than a decade of inactivity on the site and hand zoning control back to the village.
The re‑annexation request is tied to a fresh redevelopment proposal that would turn the long‑quiet land into a light‑industrial complex. Neighbors and local officials are paying close attention because whoever ends up with municipal control will also set the rules on zoning and collect the property tax revenue.
As reported by The Real Deal, Allstate filed its petition to bring the property back into South Barrington after disconnecting it from the village in 2023, a move that a Cook County judge signed off on in 2025. The new filing travels in tandem with plans from developer Opus, which has already shown village officials designs for three light‑industrial buildings on the campus. Opus executives say that if the annexation is approved, they expect the review process to move relatively quickly.
Developer’s Plan For The Site
Opus is pitching a three‑building industrial project on the 67 acres, a scaled‑back concept compared with earlier, larger redevelopment ideas for the former headquarters. Company representatives have walked officials through preliminary layouts and say the project is aimed at light‑industrial tenants, not heavy manufacturing.
The developer has indicated to village staff that it will submit formal plans to the local plan commission as the next step in the process, assuming the re‑annexation clears the political and procedural hurdles.
How South Barrington Officials Are Responding
Village leaders have already sat down with Opus executives to talk through the pros and cons of bringing the land back under South Barrington’s control. Planning director Paula McCombie told the outlet that annexation would give the village “a seat at the table,” a key point for officials who want a say in what ultimately rises on the property.
The Real Deal also quoted consultant James Vasselli, who described the re‑annexation maneuver as a rare “unicorn” in the world of local land use. Before signing off, village officials say they want to be confident that any redevelopment lines up with expectations on traffic, stormwater management and tax impacts.
Background And Lingering Questions
The former Allstate parcel has been largely dormant since the company consolidated operations in Northbrook and demolished its South Barrington headquarters after 2012. A more ambitious redevelopment plan from Hillwood surfaced in 2022 but ultimately collapsed, and the land’s legal status has shifted several times in the years since.
That stop‑and‑start history leaves some unresolved questions, including what infrastructure upgrades might be needed, how stormwater will be handled and whether light‑industrial tenants will mesh with nearby residential neighborhoods.
What Comes Next
If South Barrington approves the re‑annexation, Opus would then bring its formal proposal to the plan commission, which would start the official review clock. Any green light for construction would still have to go through public hearings and potential zoning changes, giving residents a chance to voice support or concerns.
For now, Allstate’s petition creates a possible path to finally redevelop the long‑vacant campus, while key details such as construction timing and future tenants remain undecided.
