General vs. Specialty Contractor Rules in Montana

One credential, no classes

Montana's entire construction contractor law fits in eleven sections across three parts of Title 37, chapter 45. Part 1 states the purpose, defines a construction contractor, gives the department rulemaking authority and lists the exemptions. Part 2 requires the licence and says what the record must contain, limits the hiring party's liability, deals with fees, makes the chapter exclusive as against local governments, and handles partnerships and joint ventures. Part 3 defines unprofessional conduct and sets the penalty. Read the whole thing and you will not find a classification, a scope of work, an examination or an experience requirement, because the chapter creates none.

The department says the same in the plainest possible terms on its own page: "No test is required. The CR certificate is not a license and does not ensure quality of work." That sentence was written about the old registration, and the credential has since become a licence, but nothing in the new chapter adds an examination.

So the question "am I a general or a specialty contractor in Montana" does not have a Montana answer. The credential does not describe your trade. What defines your exposure is the statutory definition at 37-45-102(1), which sweeps in anyone who for another offers to undertake, undertakes or submits a bid to "construct, alter, repair, add to, subtract from, improve, move, wreck, or demolish" a building, highway, road, railroad, excavation "or other structure, project, development, or improvement attached to real estate", expressly including "the installation of carpeting or other floor covering, the erection of scaffolding or other structures or works, or the installation or repair of roofing or siding".

The second route into the definition catches self-builders

MCA 37-45-102(1)(b) is easy to skim past and worth reading twice. It brings inside the definition a person who, in order to do work similar to contracting "on the construction contractor's property, employs members of more than one trade on a single job or under a single building permit, except as otherwise provided."

That is a multi-trade test, not a value test. If you are developing your own property and you have carpenters and masons working under one permit, the statute reaches you even though nobody hired you. Read it against the owner exemptions, because they interact. Subsection (13) of 37-45-104 exempts "an owner working on the owner's property, whether occupied by the owner or not", but withdraws that exemption where the owner "constructs an improvement on the owner's property with the intention and for the purpose of promptly selling the improved property, unless the owner has continuously occupied the property as the owner's primary residence for at least the last 12 months."

Subsection (12) does something similar from the other direction, exempting "an owner who contracts for work to be performed by a registered construction contractor" but withdrawing that from "an owner who is otherwise covered by this chapter who constructs a residence on the owner's property with the intention and for the purpose of promptly selling the improved property." Spec building on your own lot is the case both subsections are aimed at.

Where the real scope limits live: the separate trade boards

Because chapter 45 sets no scope, the credentials that do set scope are the separate trade licences, and the chapter itself points at them. MCA 37-45-104(16) exempts "an electrician or plumber, licensed in Montana, operating within the scope of the license". Subsection (19) exempts a person or entity licensed under Title 50, chapter 39 "to sell, install, or service fire suppression or fire protection equipment". Subsection (20) exempts a water well contractor licensed under Title 37, chapter 43 "performing the work of a water well contractor". Subsection (15) exempts licensed architects, civil or professional engineers and professional land surveyors "acting solely in a professional capacity". Subsection (17) exempts a contract security company licensed under Title 37, chapter 60 operating within the scope of its licence.

The Business Standards Division publishes the full index of Montana's professional boards and programmes, and the construction-relevant entries are the State Electrical Board, the Board of Plumbers, the Elevator Contractors, Mechanics and Inspectors Licensing Program, the Fire Protection License Program, the Home Inspector Program, the Construction Blaster Program, the Crane and Hoisting Operator Program, the Boiler Operator Program, the Board of Architects and Landscape Architects, the Board of Professional Engineers and Professional Land Surveyors, the Board of Sanitarians and the Private Security Program. There is no construction contractor board on that index, because the contractor credential is administered by a different division of the same department.

The electrical licence is the clearest example of a genuine scope rule in Montana. The State Electrical Board states that the Electrical Contractor licence requires a "Montana Licensed Master Electrician is responsible party for the business", and that "The Montana responsible electrician's license determines the level of the contractor's license and what electrical work can be performed. An electrical contractor license will require a Montana licensed master electrician as the responsible party and allows the electrical contractor to perform residential, commercial, industrial, and institutional work." That is a scope tier, and it belongs to the board rather than to the contractor licence.

The plumbing licence carries its own upkeep. The Board of Plumbers states that FY 26 plumbing licence renewals "open July 2, 2026, and are due by September 1, 2026", that "The license renewal fee is 100% abated; however, if you are renewing late, fees do apply", and reminds licensees to comply with ARM 24.180.2102, which requires "4 hours of continuing education completed during renewal cycle".

And the other real limit: permits and codes

The second thing that actually constrains what you build in Montana is the code and the permit, not the licence. DLI states that its Building Codes Program "establishes and enforces statewide codes by issuing permits and performing inspections", that the programme covers building, plumbing, electrical and mechanical permitting plus the elevator and boiler programmes, and that it "is responsible for adopting a uniform state building code, which is enforced statewide for residential and commercial buildings across Montana."

Who issues your permit is a geography question. DLI states that "In Montana, cities, counties and towns have the option to enforce local building, electrical, plumbing, and mechanical codes, all or in part (except for state-owned agencies, which must be permitted through this Department)", that "These local building code enforcement programs must be certified by the BC Program", and that "The remaining cities, counties and towns that have chosen not to enforce building codes, fall under the jurisdiction of the BC Program." A contractor working across several Montana counties will deal with both.

This is also where the limit on local licensing sits. MCA 37-45-204 makes the chapter's registration and licensing provisions "exclusive for registered construction contractors" and states that "A political subdivision of the state may not require or issue any registrations, licenses, or bonds for the same or a similar purpose." What a local government keeps is the power to "levy and collect a general and nondiscriminatory license fee levied upon all businesses", and its authority over contractors who are not required to be registered at all. A building permit is not a contractor licence, so nothing in 37-45-204 exempts you from pulling one.

What replaces classification as your real compliance risk

Because Montana does not police scope through the contractor licence, it polices behaviour instead, and MCA 37-45-301 is where the department's teeth are. It makes it unprofessional conduct to commit "fraud, misrepresentation, deception, or concealment of a material fact" in applying for or renewing a licence, in advertising, in written communications with a client, or in a contract or contract negotiations. It covers misappropriating funds from a client and interference with a department investigation, including "failure to respond or cooperate with requests from the department".

Three of its provisions are aimed squarely at how you use subcontractors. It is unprofessional conduct to hire or classify a person as an independent contractor where that person lacks an exemption certificate that 39-71-417 requires, where the department has suspended, revoked or denied their certificate, or where "the person is hired to work in a trade, business, occupation, or profession that is not listed on the independent contractor exemption certificate". A further provision makes it unprofessional conduct for "allowing an independent contractor to perform work not in the trade, business, occupation, or profession listed on their independent contractor exemption certificate".

That pair is the closest thing Montana has to a scope-of-work rule, and it applies to your subcontractors' certificates rather than to your own licence. It is also the reason to actually read what a sub's certificate lists before putting them on a job. A final provision covers failing to comply with the Workers' Compensation Act, the Unemployment Insurance Law, or the wage payment, minimum wage and overtime payment provisions of Title 39, chapter 3.

The consequence is set by 37-45-302: in addition to the penalties in 37-1-406, a determination of unprofessional conduct subjects the person to "a penalty of up to $5,000, as determined by the department" and "a suspension or debarment of rights to public works contracts". The department also has authority to "adopt additional unprofessional conduct standards by rule", and DLI's HB 239 notice is careful to mark the boundary: the department "does not review or evaluate the quality of a contractor's workmanship when enforcing licensing complaints."

Check the official page yourself before you file or sign

Montana splits contractor rules across at least four places: the Employment Relations Division of DLI for the contractor licence and the exemption certificate, the Business Standards Division for the electrical, plumbing, elevator, fire protection and home inspector credentials, the Secretary of State for the entity and the annual report, and the Department of Revenue for withholding and the contractor's gross receipts tax. No single page carries all of it.

Two more moving parts make a fresh check worth the ten minutes. The Commissioner has announced that "Starting mid-August 2026, both processes will move fully online", that "paper applications and renewals will be discontinued once the new system launches", and that applicants should "discard any old forms, as they will no longer be accepted." And DLI's own website and lookup tools were scheduled for an August update at the same time. If you are reading this after mid-August 2026, the form you downloaded may already be void.

DLI publishes a single number for both the contractor and the exemption certificate programmes, (406) 444-7734. Call it before you post a cheque, and keep a dated copy of whatever page you relied on.
