General Contractor Insurance in Montana

Yes, general liability insurance is considered essential for any general contractor, covering third-party bodily injury, property damage, and completed-operations claims tied to the work you perform and oversee.

General contractors are exposed on every job they run, not just their own tools and labor but the coordination of every trade on site, and a single property-damage or injury claim can exceed what most contractors can pay out of pocket.

• Third-party bodily injury on or near the jobsite
• Property damage to a client’s home, business, or adjacent structures
• Completed-operations claims after the job is finished
• Legal defense costs for covered claims

Typically NOT covered:

• Damage to your own tools, equipment, or vehicles
• Your own employees’ injuries (that’s workers’ comp)
• Faulty workmanship claims with no resulting property damage or injury in most states
• Intentional or contractual liability outside the policy terms

Who needs this: Every general contractor, solo or running crews of subs, since GCs are named in more claims than almost any single trade, and property owners and municipalities routinely require proof of GL before allowing work to start.

Montana-specific note: Montana doesn’t require GL insurance to register as a contractor, but with no licensing exam to screen operators, most clients and GMs treat a GL certificate as the real proof of legitimacy.

Yes, nearly every state requires workers’ compensation insurance once a general contractor has employees, and general contractors often carry the broadest payroll of any construction trade since a single crew can span laborers, equipment operators, and site supervisors across multiple classification codes.

General contracting work involves heavy materials, power tools, and constant movement between active trades on a jobsite, so on-the-job injuries are common, and workers’ comp is usually the only coverage that pays employee medical bills and lost wages.

• Medical bills for a work-related injury or illness
• Lost wages during recovery
• Disability benefits for permanent injuries
• Death benefits for dependents

Typically NOT covered:

• Injuries to non-employees (subcontractors typically need their own policy)
• Injuries from horsing around or intoxication in most states
• Occupational illness unrelated to the job
• Punitive damages

Who needs this: Any general contractor with employees, and in many states owner-operators too. Check the state’s specific exemption rules.

Montana-specific note: Montana requires workers’ comp starting with your first employee under the Montana Workers’ Compensation Act, and the state ranks 14th of 51 nationally for overall premium cost, a real budgeting factor for a GC with multiple trade classifications on payroll.

Sometimes, general liability may cover resulting third-party property damage or injury caused by a subcontractor’s failure, but a pure workmanship defect with no resulting damage is typically excluded, and many states still hold the general contractor responsible to the client regardless of which sub actually did the work.

A general contractor’s biggest liability exposure is often not an accident but a defect claim surfacing months or years after a subcontractor’s work is complete, and GL policies distinguish between a covered occurrence and uncovered faulty work.

• Property damage to other trades’ work caused by a subcontractor’s failure
• Third-party injury from a defect-related failure
• Damage from a sudden, unexpected event during a sub’s work

Typically NOT covered:

• The cost to repair or replace a subcontractor’s own defective work
• Damage from known site conditions no one planned for
• Gradual defects attributable to workmanship rather than a covered occurrence

Who needs this: Any general contractor coordinating multiple subcontractors on a job, since GCs are frequently named in disputes over a sub’s work product even when they weren’t the one who performed it.

Montana-specific note: Montana’s statute of repose and pre-suit notice-and-repair process for residential construction defects (MCA Title 70, ch. 19, pt. 4) put a real time limit on how long a GC can be pursued for a sub’s defective work, but don’t eliminate the exposure inside that window.

Usually, general liability covers third-party bodily injury on an active jobsite, including to a subcontractor’s crew, but if a sub is uninsured or under-insured, the general contractor’s own policy can end up absorbing exposure that should have been the sub’s responsibility.

A jobsite with multiple trades working simultaneously creates overlapping hazards, so confirming every subcontractor carries their own current GL and workers’ comp, and names you as an additional insured, is one of the most important risk controls a GC can put in place.

• Third-party or bystander injury on an active, multi-trade jobsite
• Coverage under additional-insured status when a properly-vetted sub’s policy responds first
• Legal defense costs for covered claims naming the GC

Typically NOT covered:

• Injuries a properly-insured sub’s own GL/WC should cover first
• Employee injuries, which fall under the GC’s own workers’ comp instead
• Injuries from a subcontractor’s uninsured, unvetted crew in many cases

Who needs this: Any general contractor who hires subcontractors should require a certificate of insurance and additional-insured endorsement from every sub before they start work.

Montana-specific note: Montana requires proof of workers’ comp to register, and GCs typically require subs to carry their own WC/GL and name the GC as additional insured, since Montana’s registration system doesn’t independently verify a sub’s coverage before they step on your site.

Yes, vehicles titled to your business, including pickup trucks, dump trucks, and job trailers, need commercial auto insurance since personal auto policies exclude business use.

A general contractor’s fleet is often on the road constantly moving between active jobs, hauling materials, tools, and sometimes a mobile job-site office, so a single at-fault accident can generate injury and cargo-related liability far above personal auto limits.

• Liability for injuries or property damage you cause while driving for work
• Physical damage to your own vehicles (with comp/collision)
• Hired and non-owned auto coverage for rented or borrowed vehicles
• Cargo/load-related liability in many policies

Typically NOT covered:

• Personal-use driving with no business nexus
• Mechanical breakdown or wear and tear
• Damage from operating outside permitted weight/route limits
• Cargo not covered under the specific policy’s cargo endorsement

Who needs this: Any general contractor who owns, leases, or regularly uses vehicles or trailers titled to the business.

Montana-specific note: Montana GCs moving crews, tools, and materials across wide rural distances and multiple trade classifications need commercial auto on titled vehicles and trailers, personal auto policies typically exclude business use.

Not automatically, general liability and auto policies don’t cover your own tools and equipment, so a separate tools & equipment (inland marine) policy is needed.

A general contractor’s equipment, from power tools to a mobile job-site office trailer, is expensive, mobile, and exposed to theft, drops, and jobsite damage that standard policies exclude.

• Theft of tools and equipment from a jobsite or vehicle
• Accidental damage to owned equipment and trailers
• Equipment in transit between jobs
• Rented or leased equipment in many policies

Typically NOT covered:

• Normal wear and tear or mechanical breakdown
• Equipment not listed on the schedule
• Loss from unattended, unlocked vehicles in some policies
• Gradual deterioration or rust

Who needs this: Any general contractor who owns tools, generators, job-site trailers, or other portable equipment worth protecting beyond replacing it out of pocket.

Montana-specific note: Standard property coverage usually won’t follow a GC’s tools and job trailers between Montana job sites, especially with wildfire and hail exposure in play, so scheduled equipment coverage is worth carrying separately.

In many states, yes, a license bond is a separate requirement from insurance: a surety bond financially guarantees the state or a consumer against your violation of licensing law or failure to complete a contract, while insurance protects against accidents, injuries, and property damage.

A bond isn’t liability coverage, if a claim is paid out against your bond, the surety typically requires you to reimburse it, so a bond protects the public and your license standing, not your own business from a lawsuit.

• A financial guarantee to the state or consumer if you violate licensing law
• Protection for a consumer against certain license-related misconduct
• A prerequisite to getting or keeping your license in many states

Typically NOT covered:

• Liability for accidents, injuries, or property damage (that’s GL)
• A claim against your own business’s losses
• Any payout that doesn’t ultimately get billed back to you as the bonded party

Who needs this: Any general contractor working in a state or municipality that requires a license, registration, or permit bond as part of doing business legally.

Montana-specific note: Montana is one of the few states where a general contractor bond isn’t required at all, registration only needs proof of workers’ comp coverage, so insurance (GL/WC) does more of the credibility work than bonding here.

Most commercial and municipal contracts require proof of general liability (often $1M/$2M limits), workers’ compensation, and commercial auto insurance before you can start work, and many also require a performance and payment bond.

General contractors and property owners use insurance requirements to transfer risk, and failing to meet a contract’s stated limits can get a GC pulled from a job or held liable directly.

• Minimum GL limits specified in the contract (commonly $1M per occurrence / $2M aggregate)
• Workers’ comp per state statutory limits
• Commercial auto liability, often $1M combined single limit
• Additional insured status naming the owner or awarding agency

Typically NOT covered:

• Coverage above your policy’s actual limits
• Requirements not stated in the written contract
• Retroactive coverage for work performed before the policy was active
• Waiver of subrogation unless specifically endorsed

Who needs this: Any general contractor bidding commercial, municipal, or larger residential contracts where an owner or agency sets minimum insurance requirements.

Montana-specific note: Montana public and larger commercial jobs typically require GL and WC certificates at minimum, and often a project-specific bond even though the state’s own contractor registration doesn’t require one.

Most general contractors carry $1M/$2M general liability limits, statutory workers’ comp, and $1M commercial auto liability, often layering an umbrella policy on top given the broader multi-trade exposure a GC carries compared to a single-trade subcontractor.

Coverage needs scale with project size, payroll, and the requirements written into contracts, so a small residential remodeler and a commercial GC running multiple subs on a large build often carry very different limits.

• $1M per occurrence / $2M aggregate GL as a common baseline
• Higher limits or umbrella coverage for large commercial or municipal contracts
• State-mandated WC limits based on payroll and classification
• Auto liability matched to fleet size and use

Typically NOT covered:

• One-size-fits-all coverage, limits should match actual contract requirements
• Coverage gaps from underinsuring against a specific contract clause
• Excess exposure without an umbrella policy

Who needs this: Any general contractor should review their limits against the specific contracts they’re bidding rather than assuming a flat minimum.

Montana-specific note: A GC running multiple trades in Montana typically carries $1M/$2M GL limits at minimum, sized to WC payroll exposure that runs about 22% above the national median per the Oregon DCBS 2024 study.

Your insurance agent or broker issues a certificate of insurance (COI) that summarizes your active coverage, limits, and effective dates for an owner, property manager, or municipality to keep on file.

A COI is the standard way contractors prove coverage without handing over the full policy, and most owners and awarding agencies won’t allow work to start without one matching their required limits.

• Policy type, limits, and effective/expiration dates
• Additional insured endorsements when requested
• Certificate holder information for the requesting party
• Quick verification for bidding and bonding purposes

Typically NOT covered:

• A COI itself provides no coverage, it’s only proof of an existing policy
• Coverage changes made after the COI was issued unless reissued
• Guarantee of renewal or continued coverage

Who needs this: Any general contractor working with owners, property managers, or municipalities that require documented proof of insurance before work starts.

Montana-specific note: Since Montana’s registration process doesn’t verify insurance, a current Certificate of Insurance listing GL and WC is often the only real proof a Montana GC can hand a client or GM on request.
