Ohio has 260 newly designated federal Opportunity Zones, and 14 of them sit squarely in the Mahoning Valley — seven in Mahoning County, two in Columbiana County and five in Trumbull County. The designations, part of a nationwide federal push to steer private investment into targeted communities, won't formally kick in until 2027, but local officials and developers are already eyeing what the new map could mean for downtown blocks and vacant lots across the region.
The tally comes from state-level reporting on Governor Mike DeWine's announcement, detailed by Mahoning Matters, which confirmed that 260 census tracts across Ohio now carry the Opportunity Zone label. The newly designated zones will remain in effect through 2036, giving investors an investment window of just under ten years to put money into the chosen tracts.
On the federal side, the U.S. Treasury published its full national list on November 5, certifying 6,576 Opportunity Zone 2.0 census tracts across every state and territory, according to the Economic Innovation Group. The newly designated tracts become eligible for qualifying Opportunity Zone investments starting January 1, 2027, and that eligibility runs through December 21, 2036, per the same data release. The U.S. Department of the Treasury similarly confirms the new designations become effective January 1, 2027, and hold for ten years.
What Opportunity Zones Are Supposed to Do
Opportunity Zones are a federal tool designed to pull private capital into economically distressed areas by offering tax incentives to eligible investors. Ohio's current round isn't its first rodeo with the program: the state's original round, designated in 2018, covered 320 census tracts spread across 73 counties, the same Mahoning Matters report notes.
Nationally, the first generation of Opportunity Zones — often called OZ 1.0 — drew more than $112 billion in private investment into designated communities between 2018 and 2024, according to the Economic Innovation Group. The newly certified 2.0 round covers a broader footprint: 22.9 million people, or 6.8 percent of the country's population, now live inside a designated zone, and 39 percent of all 2.0 zones — 2,594 tracts — meet the federal definition of rural.
Mixed Results From the First Round
Whether a designation alone translates into visible change on Main Street is less certain. A Brookings Institution analysis found that builds per year rose 9 percent nationally in 2019–2024 compared with 2017–2018, and Opportunity Zones' share of new U.S. building construction climbed from 5.8 percent to 6.6 percent after designation — still below the 9.9 percent share of all census tracts that OZs represent, per Brookings.
The same analysis found that 46 percent of designated zones saw building activity increase by at least 15 percent, but just 26 percent of zones experienced growth without displacement — a reminder that investment and equitable outcomes haven't always moved together in earlier rounds. Those figures describe national Opportunity Zone trends broadly and are not measurements of how Ohio's newly designated tracts will perform.
Local Tracts Join Ohio's New Zones
For now, the practical effect in Mahoning, Columbiana and Trumbull counties is that these 14 tracts have cleared the federal bar and join the broader Ohio list of 260.
