St. Peters, MO Home Business: Customer Traffic Restrictions (2026)

Section 405.380(A)(2) ties customer and staff traffic directly to the residence itself: the total number of employees and clients on the property at any one time cannot exceed the occupancy limit that already applies to the dwelling unit under the City's building and life-safety rules, so a larger house allows more simultaneous visitors than a small one. Subsection (A)(3) adds a separate, traffic-focused limit: the home-based work cannot cause a substantial increase in traffic in the area of the dwelling, regardless of whether the occupancy cap is met.

To keep client and employee vehicles off the street, Subsection (A)(10) requires a minimum of two off-street parking spaces to be provided on the premises specifically for the home-based work, on top of whatever parking the household itself needs. These three provisions work together: a home business that draws a steady stream of client vehicles, or that relies on street parking because it lacks the required two off-street spaces, is out of compliance even if it never exceeds the dwelling's occupancy limit. The Planning, Community and Economic Development Department, through Neighborhood Preservation code enforcement, investigates traffic and parking complaints against home-based work in the City of St. Peters, Missouri.
