St. Charles, MO zoning map & districts

St. Charles, a St. Louis-metro suburb and Missouri's first state capital, zones under its own municipal ordinance, administered by the city's Planning & Community Development Department, with the Planning & Zoning Commission reviewing rezonings before Council action. The city's zoning map reflects two distinct development eras: a dense historic core along South Main Street and Frenchtown, much of it covered by local historic-district design review layered on top of the modern zoning code, and newer greenfield residential and commercial growth along the I-70 and Highway 370 corridors on the city's western and northern edges.

How zoning works in St. Charles

Because St. Charles' historic districts carry design-review requirements on top of base zoning, projects on or near South Main Street or Frenchtown should expect an additional historic-preservation review step beyond standard zoning approval.
