Construction Contractor License / Registration
Broad construction-business credential for building, improvements, roofing, siding, demolition and similar real-property work.
Montana is not a prefix-first state. Broad construction businesses route through the Department of Labor & Industry’s construction-contractor license/registration framework, while electrical, plumbing, medical gas, fire protection, elevator, boiler and asbestos work use separate state boards or programs. Mechanical/HVAC activity is strongly permit-driven. This page turns that structure into practical permit-routing intelligence.

State/local permit and inspection routing is central.
Montana combines a broad construction-contractor business framework with separate professional-board and specialty-program credentials. The source explicitly says the routing acronyms on this page are labels built from official credential names—not prefixes embedded in the state license number.
General construction, remodeling, roofing, siding and demolition generally route through the DLI construction contractor license/registration framework. Electrical and plumbing have dedicated professional boards. Medical gas is an additional plumbing endorsement. Fire protection, elevator, boiler and asbestos each have their own program.
Critical routing rule: CCL/CCR does not replace a required specialty credential. For mechanical/HVAC work, combine the construction business status with state/local mechanical permit and inspection requirements and any separately required federal refrigerant credential.
These are practical routing labels for Montana’s highest-value contractor and specialty credential lanes. They identify the credential type to verify; they are not represented as embedded state license-number prefixes.
