Phase 1 Environmental Site Assessment Cost in Ohio
Ohio runs a modest discount below the national baseline in the published cost guides. Columbus has become one of the Midwest's fastest-growing logistics and data-center markets, while the state as a whole still carries the industrial Midwest's manufacturing legacy, a combination that keeps consultant demand steady without pushing pricing above average.
What tends to drive cost up in Ohio
Ohio's manufacturing and rust-belt industrial history, steel, auto parts, and chemical manufacturing among the most common, means older sites across the state, especially outside newer Columbus-area development, more frequently carry a documented history worth investigating for a Phase 1 ESA.

Frequently asked questions: Ohio
Why is Ohio below the national average?
Published cost guides put Ohio about 10% below the national baseline, similar to Michigan and Tennessee, likely reflecting a competitive Midwest consulting market rather than lower demand.
Is Columbus different from Ohio's older industrial cities?
Columbus's recent growth has been concentrated in logistics, data centers, and corporate relocations on land with a cleaner development history than some of Ohio's older manufacturing cities, though every site still needs the same ASTM E1527-21 historical review regardless of how new the current use is.
How common are RECs on Ohio industrial sites?
Older manufacturing and chemical-handling sites across the state's traditional industrial corridors turn up recognized environmental conditions more often than newer suburban development, which is why the historical-use research step matters as much as the site visit.
