Licensed Landscape Contractor in Illinois: How to Verify Before You Hire

Illinois does not have a statewide landscape contractor license. However, Illinois requires commercial pesticide applicators — including landscape contractors who apply chemicals to lawns and ornamental plants — to hold a license from the Illinois Department of Agriculture. Chicago and other Illinois municipalities also have local contractor licensing requirements that apply to landscape work. Understanding the full picture of required credentials is essential before hiring.

This guide covers Illinois's requirements for landscape contractors, pesticide applicator licensing, irrigation contractor rules, how to verify credentials, and the risks of hiring without verification.

Does Illinois require landscape contractors to be licensed?

Illinois does not require a statewide license for landscape contractors performing basic landscaping services. There is no Illinois Board of Landscape Contractors and no state-issued landscape contractor credential for standard installation and maintenance work. However, pesticide applicators and irrigation contractors have specific licensing requirements that overlap significantly with landscape contractor work.

Chicago requires home improvement contractors to hold a City of Chicago Home Repair License if they perform work within the city. This requirement applies to landscape contractors doing substantial work on Chicago residential properties. Other Illinois municipalities may have similar local requirements. Check with the city or county where work will occur for local licensing requirements before hiring.

What is the Illinois pesticide applicator licensing requirement?

The Illinois Department of Agriculture requires commercial pesticide applicators to hold a Pest Control Operator (PCO) license or Commercial Pesticide Applicator Certification. Landscape contractors applying herbicides, insecticides, fungicides, or growth regulators to customer properties must hold the applicable IDOA credential. Relevant categories include Lawn Care and Ornamental and Turf.

IDOA pesticide certifications require passing exams and maintaining continuing education for renewal. You can verify Illinois pesticide applicator credentials at ilaged.org or through the IDOA's online verification system. If your landscape contractor applies any chemical treatments to your lawn or landscaping, verify their IDOA credential before allowing any applications on your property.

What are the irrigation contractor requirements in Illinois?

Illinois does not have a statewide irrigation contractor license. In Chicago and other large municipalities, irrigation work connected to the public water supply may require the involvement of a licensed plumber. Local permits are typically required for new irrigation installations in most Illinois municipalities. Ask your contractor whether a permit is required and whether they will obtain it.

Illinois has adopted various water use efficiency standards, and many municipalities have lawn watering restrictions during dry periods. Your irrigation contractor should design systems that comply with local water use requirements and should be familiar with your municipality's current watering schedules and restrictions. A contractor unfamiliar with local water rules is a potential compliance risk.

What bond and insurance amounts should Illinois landscape contractors carry?

Illinois does not have a statewide bond requirement for landscape contractors. Workers' compensation is required for Illinois employers with any employees. Reputable Illinois landscape companies typically carry general liability insurance of $500,000 to $1 million per occurrence.

Request a certificate of insurance before any work begins. Confirm general liability and workers' compensation coverage is active with appropriate limits. For Chicago-based work, home repair licensees may have additional insurance requirements set by the City. Always request the current certificate — a lapsed policy is as risky as no policy at all.

How do you verify a landscape contractor in Illinois?

Verify IDOA pesticide applicator credentials at ilaged.org. For Chicago projects, verify the City of Chicago Home Repair License if applicable. Verify business registration with the Illinois Secretary of State at cyberdriveillinois.com. Request a certificate of insurance for general liability and workers' compensation. Check with the local building department for any permit or local licensing requirements.

For complaints, the Illinois Attorney General's Consumer Fraud Bureau handles contractor fraud complaints. Chicago's Department of Business Affairs and Consumer Protection handles complaints against City-licensed contractors. The Better Business Bureau also maintains complaint records for Illinois landscape companies in the Chicago metro area and downstate markets.

What are the risks of hiring an unverified landscape contractor in Illinois?

Illinois's limited statewide landscape contractor oversight means homeowners face elevated risk when hiring unverified contractors. An uninsured contractor who damages your property creates a financial problem with no insurance coverage. Workers without workers' comp coverage who are injured on your property create premises liability exposure.

Unlicensed pesticide applications by an Illinois landscape contractor violate IDOA regulations. Chicago's active consumer protection enforcement means that contractors operating in the city without required licenses face real regulatory consequences. The FTC reports that home improvement fraud costs consumers billions annually, and unverified landscape contractors are a common vector for that fraud.
