O'Fallon, Missouri Zoning Districts: What Do They Mean?

Zoning districts are areas regulated by specific laws that determine land use, building types, and development rules. Each district below shows its zone type. O'Fallon's ordinance does not state permitted uses as citywide flags, so they are read from each district's own table rather than summarised here.

City Context

How is O'Fallon zoned?

O'Fallon regulates land through 18 zoning districts, and two of them name a specific development intent rather than a use category.

The High Tech Corridor District covers roughly 617 acres, the seventh largest classification. Naming a corridor for its intended industry, and zoning six hundred acres for it, is a clear economic development statement written into the map.

Mixed Use Traditional Development covers roughly 480 acres, providing an explicit framework for walkable mixed development rather than leaving it to the commercial districts.

The residential system is conventional and compact: Single Family Residential at roughly 9,973 acres, a suburban single family variant at about 78, Two Family at roughly 314, Medium Density at about 1,242 and an Apartment Building district at roughly 779. A mobile and manufactured home park district covers about 283 acres.

A General Business Sports district at roughly 24 acres is an unusual variant, naming sports-related commercial use as its own designation.

Commercial otherwise runs restricted, general, highway and office, with general business the second largest classification at roughly 1,660 acres.

Industrial splits into heavy at roughly 930 acres and light at about 889. Park Recreation covers roughly 528 acres and Agricultural about 508. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
