Chesterfield, the place people mean
When people say "Chesterfield," they often mean the middle of the county: Chester and the Courthouse area along Route 10. The county was created in 1749. The county seat at Chesterfield Court House has a courthouse square listed on the National Register of Historic Places in 1992, and a newer courthouse on Ironbridge Road replaced the 1750 one in 1917.
Chester began in the 1850s as a railroad town. It grew where the Richmond and Petersburg Railroad met the Clover Hill Railroad. Chester Linear Park now follows the old Seaboard Air Line route through town.
Most homes here are much newer than that history. The county stayed rural until the 1970s. It grew from 77,045 people in 1970 to 141,372 in 1980 and 209,599 in 1990. Chester alone had 23,414 people in 2020, and its housing units grew from 6,951 in 2000 to 9,390 in 2020. So the typical Chesterfield house is a 1970s to 1990s home or a newer build, often brick front, on a crawl space or a slab. Each type needs a different kind of foundation repair in Chesterfield.
