St. Louis Region
School district boundaries don't follow city lines
School district boundaries in the County can cross municipal lines, so the city you live in does not automatically tell you the school district, and the district drives a big share of the tax levy.
The city name on a St. Louis County mailing address is not enough to know the school district. District lines can cut across municipal lines. One city can include more than one district, and one district can take in pieces of several cities plus unincorporated areas.
This is not just a school-enrollment detail. The school levy is usually the largest piece of a property tax bill, so the district tied to the exact address can change both the school question and the tax question.
For a buyer or renter, look up the address itself. Use a boundary map from the school system, Missouri’s school directory, or the county school-district map layer instead of guessing from the city name. Then read the school district line as part of the parcel’s full levy picture.
