Detailed notes

The fine print is here.

Connecticut Irrigation Contractor License

The Connecticut Department of Consumer Protection (DCP) issues the Irrigation Contractor license, which authorizes the holder to design, install, maintain, and repair irrigation and lawn sprinkler systems that connect to potable water supplies.

What This License Authorizes

Irrigation Contractors may perform, supervise, and contract for the installation, maintenance, and repair of landscape irrigation systems, lawn sprinkler systems, and related backflow prevention devices. This license is required because irrigation systems connect to public water supplies and improper installation poses cross-contamination risks.

Examination and Experience Requirements

Applicants must pass both the Connecticut Business and Law Exam and a Trade-Specific Irrigation Exam covering irrigation system design, installation practices, backflow prevention, and Connecticut water regulations. Applicants must demonstrate relevant experience in irrigation work.

Continuing Education

Connecticut does not currently require continuing education for Irrigation license holders. However, contractors should stay current with backflow prevention requirements and water conservation regulations.

Renewal Process

Renewal Period: Annually
Renewal Fee: $150

Consequences of Operating Without a License
