Illinois to District of Columbia: master electrician license reciprocity

How local licensing works. Illinois has no state electrician license and no state electrical board. The Illinois Municipal Code (65 ILCS 5/11-33-1) allows each municipality to require registration of electrical contractors, with an annual fee of $25, and provides that a contractor registered in one municipality cannot be required to register or pay a fee in another. Anything beyond registration (examinations, experience requirements, supervising or master licenses) comes from each city's or county's own ordinance.

Chicago. The Department of Buildings licenses Supervising Electricians (individuals) and Electrical Contractors (businesses); the supervising electrician is Chicago's equivalent of a master electrician. Eligibility for the supervising electrician exam is age 21 and at least 2 years of experience installing, altering, repairing and maintaining electrical wiring under a supervising electrician or equivalent, verified by supervisor letters. General and low-voltage exams are administered by Continental Testing Services (2026 fees: $150 per exam, $150 initial license, $150 annual renewal). An electrical contractor license ($150 initial, $150 renewal) is issued to a business, including a sole proprietorship, that is owned by or employs at least one licensed supervising electrician, who must perform or supervise all of the contractor's electrical work and may be the primary supervising electrician for only one contractor. Chicago's pages do not describe any reciprocity or endorsement for out-of-state licenses.

Springfield. The Building and Zoning Department issues an Electrical License to individuals who document 5 years of practical electrical experience with at least 2 years overseeing and directing electrical work and pass the ICC National Standard Master Electrician exam (W16). Applications go before the Springfield Electrical Commission; the fee is $25 and licenses expire December 31. A grandfather clause allows applicants licensed in another Illinois or out-of-state municipality with reciprocal testing to substitute proof of that exam only if the license was originally issued before 10/10/2007 and has not lapsed more than two years; otherwise the ICC exam is required.

Peoria. Electrical licenses are issued to individuals ($150 annual). Holders of Normal or Pekin licenses may register without testing; all others submit an ICC contractor exam certificate from the 2017 code cycle or newer.

Rockford. Registration only ($25 per calendar year, or free with proof of registration or license in another Illinois municipality); no exam.

Naperville and Aurora. Both accept current ICC certifications (Standard Master Electrician for commercial, Standard Residential Electrician for residential) or a license from a listed testing municipality (Naperville lists Chicago, Elgin, Libertyville, Orland Park, Ottawa, Peoria and Woodstock) in lieu of local testing. Naperville no longer renews or issues its own electrical licenses as of December 31, 2022 and registers electrical contractors through its Civic Access portal; Aurora requires a certificate of insurance naming the city.

Elgin. Requires a contractor's license from any Illinois city that gives a written NEC-based examination, or Elgin's own exam administered monthly through CLEC Enterprises.

Unincorporated Cook County. Electrical contractors must register with the Department of Building and Zoning ($150 initial, $75 annual renewal per trade), provide $1,000,000 general liability insurance naming the department, and submit a current supervising electrician's license from an Illinois city, town or village that has an electrical commission administering an examination.

Out-of-state holders. No reciprocity or endorsement path for other states' master licenses was found in any of these jurisdictions. The practical route is to pass the ICC National Standard Master Electrician exam (accepted by Springfield, Peoria, Aurora and Naperville) or a testing city's exam such as Chicago's, then register as an electrical contractor in each municipality where work will be performed.
