Verdict
No reciprocity offered
Illinois recognizes no state's contractor license, so coming from South Dakota 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 South Dakota license is wasted, but none of it substitutes for Illinois's process.
What changes, South Dakota → Illinois
| South Dakota (current) | Illinois (destination) | |
|---|---|---|
| Application fee | $140–$260 (Electrical: $60 application fee plus a separate license/reciprocal fee — Reciprocal Journeyman $80 (=$140) up to Reciprocal Electrical Contractor $200 (=$260). Licenses expire June 30 of even-numbered years and fees are non-refundable and not pro-rated. The Plumbing Commission does not publish a reciprocal fee amount.) | No reciprocity/endorsement fee exists because there is no reciprocity path; standard plumber licensing fees apply and were not captured. |
| Processing time | ~4 weeks (The official electrical license application states 'The application process takes approximately 30 days.') | Not applicable — no reciprocity path. |
| Licensing authority | South Dakota Electrical Commission and State Plumbing Commission (Department of Labor and Regulation) | 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.
