Readiness checklist
Four things you need to confirm before you can treat Montana as “ready” for a bid or an application. If any of these are unclear, you are not ready yet.Classify the project lane
Identify whether the work is general construction, electrical, plumbing, home inspection, or highway specialty.
Register with DLI
All construction work requires DLI registration (
$70 for two years) and Montana workers’ comp coverage with MT in section 3A.Route to the trade board
If the work involves electrical or plumbing, apply separately to the State Electrical Board or Board of Plumbers. General construction stops at DLI registration.
If you can identify lane, registration status, trade board (if applicable), and requirement set, you have the minimum package needed for a Montana readiness check.

Reciprocal agreements
Montana does not operate a traditional state-to-state license reciprocity program for general construction. Workers’ comp extraterritorial agreements allow certain out-of-state coverage to follow workers into Montana. The electrical and plumbing boards accept CE from states with reciprocity, but the specific partner states are not published in general reference sources — confirm with each board directly.Workers’ comp extraterritorial agreements are not the same as license reciprocity. They cover insurance portability, not credential recognition.
| Agreement type | States | Coverage |
|---|---|---|
| Workers’ comp extraterritorial | Idaho, North Dakota, South Dakota, Oregon, Utah, Washington, Wyoming | 7 states |
| Electrical Board | Confirm with Board — CE from reciprocal states accepted | Board-specific |
| Board of Plumbers | Confirm with Board — CE from reciprocal states accepted | Board-specific |
