Start with the parcel, not the mailing city
The St. Louis region includes an independent city, counties and municipalities with different processes. A “St. Louis” postal address or company service radius does not identify the authority that will review a new home.
Record the property address and parcel information, then confirm zoning, building and trade responsibilities with the relevant office. Ask the builder to include the required approvals in its schedule and scope.
Chesterfield: obtain municipal zoning approval first
Chesterfield’s development code requires municipal zoning approval before a building permit. Confirm the current submission and inspection offices directly with the city for the property.
For an established-neighborhood teardown or addition, ask which site-plan, notification and design-review submittals apply. Keep private subdivision approval questions separate and establish responsibility for each task in the proposal.
Kirkwood: architectural review is a separate step
Kirkwood provides an Architectural Review Board process and a reference packet for new single-family residences. Its current page says stormwater/engineering review begins after a separate building-permit submission.
Ask which review applies to the proposal, who prepares supporting information and how comments are resolved. Architectural discussion should not be confused with permission to begin construction.
Webster Groves: registration and project review
Webster Groves says permits are issued to city-registered contractors, with the stated exception for an owner acting as general contractor on their own occupied home. Its zoning rules also address use, dimensions, coverage, height and setbacks.
Check the exact contracting entity and applicable registration. The fact that a builder’s website names Webster Groves does not independently verify its current registration.
St. Louis City and St. Charles have their own offices
St. Louis City’s residential guidance requires permits for new construction and identifies separate trade permits where applicable. It also points out special rules for historic districts and flood zones.
The City of St. Charles provides its own building review and inspection process and highlights historic-district and floodplain considerations. Verify whether a St. Charles-area parcel is in that city or another county jurisdiction before using its application.
Plan the final approval and handover
Ask who schedules inspections, retains approved plans and resolves corrections before work is concealed. Record the final approval and occupancy requirements that apply to the home.
Keep permit and inspection records with the contract, plans, specification changes and warranty documents. This creates a clearer record of what was authorized, inspected and delivered.
