County occupancy permits focus on unincorporated addresses

A St. Louis mailing address does not answer the occupancy-permit question by itself. The first question is whether the property is in unincorporated St. Louis County or inside a municipality with its own local process.

County occupancy inspections focus on safety and health for properties in unincorporated St. Louis County. County zoning guidance uses the same kind of check: verify that the parcel is actually in unincorporated County before relying on County zoning.

For a buyer, renter, landlord, or agent, this is a boundary errand before it is a paperwork errand. Find the municipality first. If the address is unincorporated, use the County occupancy and zoning lanes. If it is inside a city, ask that city how its occupancy rules work.
