Flint Hill, Missouri
A small incorporated city of larger lots, rural-residential roads, and growing neighborhoods just north of Wentzville.
01 / 01
St. Theodore Parish, a historic Flint Hill landmark
Kyle’s Local Take
Flint Hill sits immediately north of Wentzville along Route A and near US 61, creating a rural-suburban transition rather than a conventional dense city. St. Theodore Parish is a visible historic anchor, and the housing mix includes older homes, ranches, custom construction, subdivisions, and small acreage. The convenience is straightforward—Wentzville retail, employment, and highways are nearby—but buyers need to distinguish the incorporated city from the wider mailing area. School district, public water, wastewater or septic, electric provider, road responsibility, subdivision rules, and future development all require parcel-level confirmation.
