The Foundation of Chicago’s Electrical Contractor Licensing

To obtain an electrical contractor license, a business must employ at least one individual who is a licensed supervising electrician. This fundamental requirement creates a clear chain of responsibility and expertise that protects property owners from unqualified electrical work.

A licensed electrical contractor is required to perform all electrical work that requires a building permit in Chicago. The electrical contractor and its supervising electrician are responsible for ensuring that the permitted electrical work is performed safely, competently, and in accordance with the scope of the permit and the requirements of the Chicago Construction Codes.

Two-Tier Licensing Structure

Chicago’s electrical contractor certification system operates on two distinct levels:

• A “general” license allows the licensed business and its employees to perform any type of electrical work, subject to limitations described below.
• A “low voltage” license only allows the licensed business and its employees to perform electrical work involving Class 1, 2 and 3 remote-control, signaling and power-limited circuits and communications circuits.

The electrical contractor must maintain records showing compliance with this requirement at the work site and for at least two years following completion of the work. This documentation requirement provides property owners with verifiable proof of worker qualifications.

Supervising Electrician Requirements

Ongoing Compliance and Renewal

The certification system includes built-in safeguards for ongoing compliance. An electrical contractor license is valid for one year from issuance. An electrical contractor license is automatically inactivated if there is no valid supervising electrician license associated with the contractor license. This annual renewal requirement ensures that contractors maintain current qualifications and stay updated on code changes.
