STATE LICENSE
ConditionalSee what applies
Mowing, planting, grading, and hardscape need no state trade license in Illinois, and the Home Repair and Remodeling Act expressly excludes landscaping from its definition of home repair. The credentials attach to two adjacent services.
Applying any pesticide or herbicide for hire requires an IDOA Commercial Applicator license — $300 for the multi-year license from 2026 (up from $240) — with $50,000 in bond or liability coverage, and crew members need operator licenses. Lawn sprinkler installation falls under the Plumbing License Law: non-plumbers must register annually with IDPH as irrigation contractors, post a $20,000 bond, and have a licensed plumber inspect every system.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
No local landscaping trade license is created by state law. Irrigation registration is state-run except in a city of 500,000+ that adopts an equivalent ordinance (225 ILCS 320/16.1), and plumbing-law registration is otherwise preempted from home-rule units (§ 42). Retaining walls and drainage work follow local permit rules; in Chicago, permitted building work runs under a licensed general contractor.
