STATE LICENSE
ConditionalSee what applies
Mowing, planting, hardscape, and grading need no Kansas state credential. The trigger is chemicals: K.S.A. 2-2440 bars any business from applying pesticides — which include herbicides — on another person's property without a Kansas Department of Agriculture pesticide business license, issued only when the business employs a certified commercial applicator in each category. For lawn and landscape work the categories are 3A (Ornamental), 3B (Turf), and 3C (Interior Landscape).
The license is $140 per category per calendar year plus $15 per uncertified employee applicator (falling to $112 and $10 on July 1, 2028), and since January 1, 2025 the business must file liability insurance ($25,000 BI / $5,000 PD per occurrence) or a $6,000 surety bond. Separately, Wichita/Sedgwick County's MABCD licenses Lawn Irrigation as a trade contractor class.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Pesticide licensing is exclusively state (KDA). Irrigation and any electrical or plumbing connections are licensed locally — MABCD licenses Lawn Irrigation, and line-voltage wiring or water connections fall under local electrical and plumbing licensing where it exists.

Pure landscaping carries no state license fee; credentials start when you apply chemicals on a client's property.
Herbicides are pesticides under Kansas law — spraying weeds for hire needs the business license and a certified applicator in the turf or ornamental category.
