Verdict
No reciprocity offered
Illinois recognizes no state's contractor license, so coming from New Jersey changes nothing — it is a full application either way. The practical plan: identify which Illinois license class matches your work, book the business/law and trade exams, and prepare the financial statement and bond early. Nothing about your New Jersey license is wasted, but none of it substitutes for Illinois's process.
What changes, New Jersey → Illinois
| New Jersey (current) | Illinois (destination) | |
|---|---|---|
| Application fee | $110 (Home Improvement Contractor registration fee; this is a registration, not a license, and involves no exam) | No reciprocity/endorsement fee exists because there is no reciprocity path; standard plumber licensing fees apply and were not captured. |
| Processing time | Board does not publish a stated processing time | Not applicable — no reciprocity path. |
| Licensing authority | New Jersey Division of Consumer Affairs — Regulated Business Section (Home Improvement Contractors) | Illinois Department of Public Health — Plumbing Program (general contractors are licensed municipally) |
The destination column is what you must satisfy — Illinois sets the rules for this move.
