Illinois trade 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. Employees of an electrical contractor are expressly excluded from the statutory definition of 'electrical contractor', so state law does not require any personal license for a journeyman-level worker.

Chicago. The Department of Buildings licenses Supervising Electricians (individuals) and Electrical Contractors (businesses). There is no Chicago journeyman license. The supervising electrician exam requires age 21 and at least 2 years of experience under a supervising electrician or equivalent, verified by supervisor letters; general and low-voltage exams are offered through Continental Testing Services (2026 fees: $150 exam, $150 initial license, $150 annual renewal). For 'Class 1' work (buildings over 55 feet or large assembly occupancies before a certificate of occupancy), every worker must be a licensed supervising electrician or have completed or be enrolled in a U.S. Department of Labor-recognized apprenticeship of at least 8,000 hours; this apprenticeship standard is the closest thing Chicago has to a journeyman qualification. All other work is done by employees under the contractor's supervising electrician. 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 electrical experience (2 supervisory) and pass the ICC National Standard Master Electrician exam (W16); the Springfield Electrical Commission approves applications and the fee is $25. A limited grandfather clause applies to licenses from other Illinois or out-of-state municipalities with reciprocal testing that were issued before 10/10/2007; otherwise the ICC exam is required. Contractors performing work in the city must also register.

Peoria. Electrical licenses are issued to individuals, not businesses ($150 annual). Holders of Normal or Pekin licenses may register without testing; everyone else must submit an ICC contractor exam certificate (2017 code cycle or newer).

Rockford. Electrical contractors are not licensed, only registered ($25 per calendar year, or free with proof of current registration or license in another Illinois municipality).

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 in lieu of local testing; Naperville stopped issuing its own electrical licenses after 2022 and now registers electrical contractors. Insurance naming the city is required.

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

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

Out-of-state holders. None of these jurisdictions publish a reciprocity or endorsement path for licenses from other states. In practice the portable credentials inside Illinois are the ICC National Standard Master/Residential Electrician exams and licenses from testing municipalities such as Chicago; an electrician arriving from another state should expect to take the ICC exam or the local exam and apply separately in each municipality that licenses individuals.

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.

How local licensing works. There is no state HVAC license and no state mechanical board, so each municipality decides whether to license or register mechanical contractors, and the largest ones use the ICC National Standard Master Mechanical exam (G29/N29) as the test of competence. No verified jurisdiction licenses journeyman-level HVAC workers.

Chicago. The Department of Buildings licenses general contractors (Classes A-E, $300 to $3,500 a year with insurance from $1 million per occurrence) and specific trades such as supervising electricians, but has no HVAC or mechanical contractor or technician license; HVAC firms pull permits under a general contractor license and employees need no card.

Springfield. The Building and Zoning Department issues a Mechanical License to individuals (Residential: 5 years of experience and the ICC Master Mechanical G29 exam; Commercial: 7 years and the same exam) and separately registers mechanical contractors. There is no journeyman license; workers operate under the licensed individual.

Peoria. HVAC contractors are licensed or registered ($150 a year) on an ICC contractor test certificate from the 2018 code cycle or newer; holders of Normal or Pekin licenses register without retesting. No employee license.

Aurora and Elgin. Both accept the ICC Master Mechanical certification (Aurora N29, Elgin G29) or, in Elgin, a license from any Illinois city that gives a written exam; Aurora requires insurance naming the city and Elgin a $20,000 license and permit bond. Neither licenses employees.

Unincorporated Cook County. HVAC contractors register as 'all other trades' ($150 initial, $75 annual, $1,000,000 liability insurance); no exam and no employee license.

Not verified. Naperville's contractor registration page could not be opened for this entry, and Rockford's site describes only electrical registration.

Out-of-state holders. No jurisdiction checked recognizes another state's journeyman HVAC license, because none issues one. The portable credential inside Illinois is the ICC Master Mechanical exam, which Springfield, Peoria, Aurora and Elgin all accept for the contractor-level license.

How local licensing works. Illinois has no state HVAC license. Each municipality licenses or registers mechanical contractors under its own ordinance; the ICC National Standard Master Mechanical exam (G29, formerly W29; residential W32) is the common denominator among testing cities.

Chicago. No HVAC or mechanical contractor license. Contractors obtain a General Contractor license from the Department of Buildings in Class A (unlimited project value, $3,500), B ($1,800), C ($1,300), D ($900) or E (projects up to $500,000, $300), each valid one year, with commercial general liability insurance from $1 million per occurrence (Class E) to $5 million (Class A) and a financial solvency statement, administered through Continental Testing Services; no trade exam.

Springfield. The Building and Zoning Department issues a person-held Mechanical License: Residential requires 5 years of practical experience in all types of mechanical work approved by the Mechanical Commission and proof of passing the ICC Master Mechanical Exam G29; Commercial requires 7 years and the same exam. Mechanical contractors also register with the city. A contractor licensed in another Illinois or out-of-state municipality with reciprocal testing may substitute that test only if the license was issued before 10/7/2007 (10/10/2007 in the earlier memo) and never lapsed; all others pass the ICC exam. Passing the exam does not itself guarantee a license.

Peoria. HVAC contractors must be licensed or registered ($150 non-refundable, calendar year) with an ICC contractor test certificate from the 2018 or newer code cycle; holders of current Normal or Pekin licenses register without retesting. Only the licensed contractor may pull permits and must attend inspections.

Aurora. Accepts a current ICC Master Mechanical certification (N29) in lieu of municipal testing; requires a certificate of insurance naming the City of Aurora as primary and non-contributory additional insured; registration through Development Services.

Elgin. Requires a mechanical contractor's license from any Illinois city that gives a written examination, or proof of passing the ICC Master Mechanical G29 exam, plus a $20,000 license and permit bond; the license is not required when an Illinois-licensed architect or engineer seals the plans and accepts responsibility.

Unincorporated Cook County. HVAC contractors register as 'all other trades' with the Department of Building and Zoning: $150 initial and $75 annual per trade, $1,000,000 general liability insurance naming the department; no exam.

Not verified. Naperville's contractor registration page was blocked when opened for this entry; Rockford publishes only electrical registration rules.

Out-of-state holders. None of these jurisdictions publishes reciprocity or endorsement for another state's master HVAC or mechanical license. The practical route is to pass the ICC National Standard Master Mechanical exam (accepted by Springfield, Peoria, Aurora and Elgin), then license or register in each municipality where work will be performed, and obtain a Chicago general contractor license for work in Chicago.
