St. Louis County, MO Short-Term Rentals: Parking Rules (2026)

St. Louis County Revised Ordinances (SLCRO) Section 1003.165 (Off-Street Parking and Loading Requirements—General) within the county Zoning Ordinance (Chapter 1003) sets minimum off-street parking standards by land use type, including single-family residential, two-family, multi-family, and lodging uses. SLCRO Section 1003.166 governs residential appearance and design criteria including driveway and parking pad surfacing requirements (typically asphalt, concrete, or approved permeable hard surface). The county zoning ordinance does not contain a STR-specific parking standard, so vacation rentals in unincorporated areas default to the underlying residential parking minimum for the dwelling type. Driveways must be maintained by the homeowner. On-street parking in unincorporated areas is governed by SLCRO Chapter 1207 (Parking) and county police power; many subdivisions, neighborhood associations, and the county's traffic code restrict overnight on-street parking, blocking sidewalks/fire hydrants, and commercial vehicle storage. Cities like Maryland Heights, Kirkwood, Florissant, and Chesterfield set their own parking minimums and overnight street rules within their boundaries.
