Contractor License & Permit Bonds in Montana

Montana just moved from registering contractors to licensing them — and it still does not bond a single one of them

On 1 January 2026 Montana replaced its old construction contractor registration regime with a construction contractor license. The chapter that ran registration for thirty years, MCA Title 39 Chapter 9, is now renumbered and repealed in its entirety; the new chapter is MCA Title 37 Chapter 45. If you searched for a Montana contractor bond before this year and again after it, you were reading two different statutes.

The answer did not change. Montana licenses contractors. It does not bond them. MCA 37-45-201 lists exactly four things a license application must contain: your social security number, proof of compliance with workers’ compensation laws, your federal employer identification number if you have one, and the names and addresses of the owners, officers or members. There is no fifth item, and there is no bond section anywhere in the chapter’s three parts. If a search result offers you a “Montana contractor license bond,” there is no such instrument to buy.

The same is true of the licensed trades. Montana licenses electricians under MCA Title 37 Chapter 68 and plumbers under Chapter 69, and neither chapter contains a bonding provision — the electrical contractor section is an application and a fee, the plumbing section is residence, age, experience and an examination. Both trades are expressly exempted from the construction contractor chapter when working within the scope of their license. Whatever a Montana electrician or plumber posts a bond for, it is not the state license.

The state owns licensing, the cities own their streets — which is why every Montana contractor bond secures work in the public way

Montana has an unusual statute that shapes the whole picture, and it is worth reading before you assume a city bond exists. MCA 37-45-204 makes the construction contractor chapter exclusive: a political subdivision of the state “may not require or issue any registrations, licenses, or bonds for the same or a similar purpose” as state licensure. A Montana city cannot bond you for the right to be a contractor. The state has taken that ground and then declined to put a bond on it.

But the preemption has a limit, and the limit is the entire municipal layer on this page. It reaches bonds for the same or a similar purpose as licensure — the right to contract. It does not reach the right to dig up a street. Montana cities retain their own street and right-of-way powers, and that is what they bond. Every municipal record here secures work in the public way: opening a street, excavating in a right-of-way, moving a building across one, or building the sidewalk, curb and gutter that sit in it. None of them bonds contractor licensure, because none of them lawfully could.

Kalispell is the clean illustration. The city is sometimes listed as having a contractor license bond; its license chapter contains no bond at all. What Kalispell does bond is moving a house or building across its streets — and even there the ordinance lets a cash deposit in like amount stand in place of the bond, so the requirement is confirmed when you apply.

Missoula bonds four different ways, and the four are easy to confuse

Missoula runs the densest municipal bonding in the state, and it puts most of it in one section of its license code — MMC § 5.08.140, headed Surety bonds required, which calls for a surety bond in the sum specified for every business the code bonds. Four instruments sit under it, and they are genuinely different bonds with different obligees, different purposes and different amounts.

The bonded right-of-way contractor bond is $10,000 (MMC § 12.08.030). Missoula makes right-of-way work a licensed trade in its own right: it is unlawful to build or repair sidewalks, curb and gutter or paving in the public way without holding that license, and the bond stays answerable for two years after the City Engineer’s final inspection, specifically for defective materials and workmanship.

The oversize load and house mover bond is $20,000 (MMC § 5.70.020), and it indemnifies the City against damage to its thoroughfares — the streets your load travels over — rather than against defects in construction work. The City Treasurer reviews your qualifications and your equipment before the license issues.

The gas fitting and piping contractor bond is $3,000 (MMC § 5.08.140(E)), and it is a continuous obligation rather than a per-job one: the code requires it to be kept on file with the city clerk and in full force and effect at all times, conditioned on performing gas piping and appliance work in a skillful and workmanlike manner. It is easy to miss, because Missoula also names gas fitters in a separate insurance section — the insurance requirement is not the bond.

The fourth is the excavation permit bond, and it is the one we do not publish a figure for. The code does not fix a sum: it sizes the bond to your contract amount and then sets a minimum below which it may not fall. It is required of all applicants for excavation permits without exception, and what it answers for is unusually specific — if backfill settles or your surface patch fails within two years of acceptance, the code treats that as conclusive evidence of defective work and the city may re-excavate and assess the cost against the bond. Because the amount depends on the job, it is quoted rather than looked up.

Billings and Columbia Falls publish their amounts — and the figure circulating for Whitefish belongs to its neighbor

The Billings excavation bond is $10,000 (BMCC § 22-301 and § 22-302). Billings will not let you dig, tunnel or open up a street or alley without a permit, the fees, and a good and sufficient surety bond, and the code both states the sum and requires the bond to be executed by a surety company authorized in Montana. Two practical points it is explicit about: the bond number assigned by the surety must appear on the face of the bond, and the City will not accept continuation certificates to renew it — so a fresh bond is filed rather than the existing one extended. Its scope is the digging only; connecting and installing water or sewer pipe requires a separate utility bond under the plumbing code, and a contractor doing both carries both.

The Columbia Falls excavation bond is $5,000 (CFMC § 12.32.030). No excavation permit issues until the bond is on file with the city clerk, and it does two things: it indemnifies the city for loss arising from the excavation itself, and it separately guarantees that the surface is restored and then maintained in as good a condition for twelve months after completion as it was beforehand.

A note for anyone working in the Flathead. A $5,000 excavation figure is often attached to Whitefish. It belongs to Columbia Falls, six miles down the valley. Whitefish’s code has no excavation chapter and no excavation bond — its public ways title covers sidewalks, streets, parks, special events, vegetation and small wireless facilities, and none of them carries one. If you are excavating in Whitefish, ask the city what it wants; do not go looking for a bond the code does not require.

The one state-level bond — and why we quote it rather than publish the number

Montana’s single state board bond belongs to well contractors. The Board of Water Well Contractors requires security of every licensed water well contractor, water well driller and monitoring well constructor before that person commences operations in the state (MCA 37-43-306). It is unlawful to construct, drill, alter, abandon, decommission or rehabilitate a well in Montana without the license, and the security must be in place first.

We do not publish its amount, and the reason is in the statute’s own sentence. It calls for a good and sufficient surety bond or its equivalent in a certificate of deposit, a cashier’s check, a bank draft or a certified check — four non-surety routes, all approved by the board, all sitting alongside the bond in the same requirement. Where a state gives you that choice, the sum is not the price of a bond; it is the size of a security you may satisfy several ways. Two further routes narrow it again: a state or federal employee already bonded by the government supplies nothing during that employment, and a firm with more than two licensed contractors may file one bond covering the whole firm.

The rest of the municipal layer: who requires the bond, and who sizes it

The remaining Montana records are real requirements with amounts that live outside the ordinance. The distinction that matters is between a code that sets the amount — which is why Billings and Columbia Falls carry figures above — and an obligee that sizes it per permit, which is why these do not.

Helena requires an indemnity and performance security bond before you open a city street, alley or roadway, guaranteeing that the surface and subsurface are replaced to city street construction standards. Bozeman requires a performance and maintenance bond and lets the city manager establish the amount by administrative order. Great Falls requires a bond in a penal sum established by City Commission resolution, and one instrument covers the street, avenue, alley, sidewalk, boulevard or any other public way — so a street opening and a sidewalk are the same bond there, not two. Belgrade requires a street opening bond on file before any right-of-way work, sets the amount by council resolution, and lets the bond be posted in cash instead.

Livingston requires a surety bond conditioned to restore all openings and excavations and maintain them for two years, and states no amount anywhere in the article. Butte-Silver Bow goes further still: its right-of-way chapter defines the word “bond” to mean lawful money of the United States, or a cashier’s check, certified check, bank money order or bank draft, or a surety bond — so both the instrument and the sum are settled at permit stage. And Flathead County publishes its own road work permit bond form, running to the county for two years and conditioned on returning the roadway to its prior condition — with the penal sum left blank for the Road Department to fill in.

If your work crosses several jurisdictions, or the town you are permitting in is not named above, the general-use records cover the pattern: a street opening and right-of-way bond, a road bond, and a land disturbance bond. Every Montana bond on this page is quoted through our form rather than an instant portal, because in this state the requirement is nearly always confirmed with the obligee before it is priced.
