What Are Missouri Impact Fees?
Missouri lacks a general impact fee statute; charter cities use home-rule authority for tools like Kansas City-area road impact fees, while most jurisdictions rely on water and sewer connection charges, MSD wastewater fees in St. Louis, and subdivision improvement requirements.
St. Charles County and the Kansas City Northland are the most active growth markets for one-time charges. Missouri figures on impactfees.org are model estimates for early comparison — confirm each city's ordinance and utility district schedules.
Missouri figures are illustrative estimates from our statewide cost model — calibrated to local construction costs and community size — rather than verified fee schedules. Use them for early budgeting and site comparison, and see our methodology for how estimates are built.
