Montana Contractor License Requirements

Indexation gate: passed

Montana regulates the construction industry through mandatory statewide Construction Contractor Registration with the Montana Department of Labor & Industry (DLI) under MCA Title 39, Chapter 9. Anyone who bids on, advertises, or performs construction or alteration work must hold an active DLI Certificate of Registration. To register, contractors must maintain mandatory workers' compensation insurance or obtain an official Independent Contractor Exemption Certificate (ICEC) under MCA § 39-71-417. General contractors are exempt from statewide trade exams, while electrical contractors and plumbers are licensed by state professional boards under MCA Title 37, Chapters 68 & 69.

1. Statewide Construction Contractor Registration (MCA Title 39 Ch. 9)

Under MCA § 39-9-201, it is unlawful to act as a contractor, bid on projects, or advertise construction services without an active Certificate of Registration issued by the Montana Department of Labor and Industry (DLI).

Scope: Applies to general construction, framing, roofing, drywall, carpentry, and subcontracting.
Fee & Renewal: $70 registration fee, renewed biennially (every 2 years) under MCA § 39-9-206.
Enforcement: Working without active registration is a misdemeanor subject to a $500 fine per violation.

Montana does not require a statewide trade exam or monetary net worth ceiling for general building contractors. Registration with the DLI is administrative and compliance-focused, requiring proof of insurance or ICEC status rather than a technical license exam.

Municipal building departments (e.g. Billings, Missoula, Bozeman) issue construction permits and enforce local building codes based on the contractor's active DLI registration number.

2. Workers' Compensation & Independent Contractor Exemption (ICEC)

Proof of compliance with the Montana Workers' Compensation Act (MCA Title 39, Chapter 71) is a strict statutory condition for obtaining or maintaining contractor registration:

Standard Employer Route

Any contractor employing one or more workers must provide a Certificate of Insurance evidencing active Montana workers' compensation coverage from a certified carrier or the Montana State Fund.

ICEC Exemption Route

Sole proprietors and partners who have no employees may apply for an Independent Contractor Exemption Certificate (ICEC) from the DLI ICEC Unit ($125 biennial fee). The ICEC legally waives coverage requirements for the individual.

3. State Professional Trade Licensing Boards

Electrical contracting businesses must obtain an Electrical Contractor License ($175/year) and employ a designated licensed Master Electrician ($175/year).

Electricians must pass standardized trade examinations, verify 8,000+ hours of experience, and complete 16 hours of continuing education per 3-year National Electrical Code (NEC) cycle.

Plumbing work must be performed or supervised by a licensed Master Plumber ($250/year) or Journeyman Plumber ($190/year) licensed by the Montana Board of Plumbers.

Requires 5 years (minimum 7,500 hours) of certified experience, a state plumbing examination, and 4 hours of annual continuing education on the Uniform Plumbing Code.

4. Building Permits & Local Inspections (MCA Title 50 Ch. 60)

While contractor registration is administered at the state level by the DLI, physical construction permits are enforced locally. Under MCA Title 50, Chapter 60, contractors must pull building permits before commencing structural alterations, framing, roofing replacements, plumbing installations, or electrical work from certified municipal building departments (e.g. City of Billings, Missoula, Great Falls, Bozeman, Helena) or the State Building Codes Bureau.
