Concrete Permits & 811 in St. Louis

Permit responsibility depends on the address and full scope—not simply whether the material is concrete. Driveway approaches, curb or sidewalk work, attached structures, grading, utilities, and public right-of-way work deserve an early check.

Who may have authority?

Depending on the property, that may be a municipality, St. Louis County, another county, a road district, a state transportation agency, a sewer or utility district, a homeowners association, or more than one entity. Ask the provider to identify the authority and show required approvals before work begins.

St. Louis City driveways

The City of St. Louis publishes a driveway permit service for new and reconstructed residential driveways. Review the current application, fees, and process directly with the Street Department.

St. Louis County and municipalities

St. Louis County publishes residential permit guidance and separate information for work on county roads, including residential driveways. Many incorporated cities administer their own rules, so a St. Louis County mailing address does not by itself identify the permit authority.

Call before excavation

Missouri One Call and Illinois JULIE provide official utility-notification channels. Public utility locates do not necessarily identify every private line, such as irrigation, lighting, gas to a grill, or privately installed electric. Discuss private-locate needs before demolition or excavation.

Agency pages can change. Confirm current requirements for the exact address and scope. This guide is general information, not legal, engineering, or code advice.
