How these numbers are made
  • Property tax: 2025 St. Louis County rate book, tax code 117 (Olivette, Ladue School District), residential rates per $100 of assessed value, applied to 19% of the Census median home value; the Olivette city rate in the book is $1.014 per $100.
  • The city's Tax Revenue Overview states $1.044 per $100 for 2025 bills; the county rate book figure is used because it is what the county bills. Other Olivette tax codes (117AC, 117AK, 117IB, 117IC) are variants of the same Ladue district area.
  • Water: Missouri American Water Rate A for St. Louis County ($11.00 per month, $10.3749 per 1,000 gallons) plus the $0.75071 per 1,000 gallons surcharge effective Aug. 15, 2026. A rate case filed July 1, 2026 is pending. The 10% city gross receipts tax applies to water, natural gas, electric and phone bills; the page applies it to the water, electricity and gas lines, not to the MSD sewer bill (no source applies it there).
  • Sewer: MSD base charge $34.85 per month plus $7.15 per CCF of winter-quarter water use; use here is the household water use. Trash: the $8.71 monthly single-family user fee is the figure in the city code (effective July 1, 2010, 'subject to change'); the city pays the rest of the Republic Services contract.
  • Electricity: Ameren Missouri Schedule 1(M), summer and winter blended by months, with the 0.445¢ fuel adjustment excluded from the annual blend; gas: Spire Missouri St. Louis County rates, both with the city 10% gross receipts tax.
  • Nothing here is legal, tax or insurance advice.
