St. Louis, 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. St. Louis's ordinance does not state permitted uses as citywide flags, so they are read from each district's own table rather than summarised here.
| Zone Code | Category | Area | Details |
|---|---|---|---|
A Single Family Dwelling District | - | 10,125.6 ac | Standards & uses → |
K Unrestricted District | - | 5,320.6 ac | Standards & uses → |
B Two Family Dwelling District | - | 4,740.7 ac | Standards & uses → |
C Multiple Family Dwelling District | - | 2,397.7 ac | Standards & uses → |

St. Louis regulates land through only 12 zoning districts, lettered A through L, and the naming convention carries no descriptive information at all. The letter has to be looked up: A is single family dwelling, B two family, C, D and E multiple family at different intensities, F neighborhood commercial, G local commercial and office, H area commercial, I central business, J industrial, K unrestricted and L the Jefferson Memorial district.
Two of those deserve attention.
The K district, Unrestricted, covers roughly 5,321 acres and is the second largest classification in the city. An unrestricted district at that scale is genuinely unusual in a major American city, and it means a very large share of St. Louis sits under the least constrained designation on the map. For anyone evaluating a site, establishing whether a parcel is in K changes the analysis entirely.
The L district covers the Jefferson Memorial at roughly 181 acres, zoning the national memorial grounds as its own classification.
Single Family Dwelling coded A is the largest district at roughly 10,126 acres and Two Family Dwelling coded B covers about 4,741. The three multiple family districts together cover roughly 3,583 acres.
With twelve districts the standards do all the work the categories do not. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
