Missouri Landscaping Contractor License Requirements (2026)

Missouri does not issue a state-level landscape contractor trade license. The mandatory state credential is a Commercial Pesticide Applicator certification issued by the Missouri Department of Agriculture (MDA) Pesticide Control Program under RSMo Chapter 281. Cities such as Kansas City, St. Louis, Springfield, and Columbia each require local landscape contractor registration in addition to state pesticide certification. Kansas City specifically requires landscape contractors to register with the Department of Neighborhoods and Housing Services for landscape work that includes hardscape, drainage, or grading.

Regulatory Body Profile

Licensing for this trade is governed by City of Kansas City, Missouri — Code Compliance Division, Department of City Planning and Development (KCMO), the agency that issues and regulates the credential under Kansas City Code of Ordinances Chapter 18 (Buildings and Building Regulations). Kansas City Code Compliance Division licenses general contractors, master and journeyman electricians, master and journeyman plumbers, and mechanical (HVAC) contractors operating inside KCMO city limits. It administers examinations, issues permits, and enforces the adopted building, electrical, plumbing, and mechanical codes.
