Business insurance for carpenters in Michigan
Published 2026-06-11 · by Brokly
Covers finish, cabinet, and trim carpentry contractors — framing, general carpentry, and new-dwelling construction are rated separately and aren’t in these figures.
What insurance do Michigan carpentry contractors need?
Each requirement and definition below cites its statute, regulator, or public reference — full sources at the end of this section.
You're required to have
Covers your carpenters' on-the-job injuries — and construction carve-ins start the mandate at one employee in some states.
Required once you have 3 or more employees at one time (part-time included) — or even a single employee, if that employee regularly works 35 or more hours per week for 13 weeks or longer during the preceding 52 weeks.
Pays medical care and lost wages when an employee is hurt working. Cabinet and trim installation is treated as construction work in states with construction-industry carve-ins, which apply a lower employee threshold — Missouri's rule names carpenters outright, and Florida reaches one-employee crews. Finish carpentry is hands-on power-tool work — table-saw, router, and nail-gun injuries make employee injury the trade's first insured risk.
Typically covers
- Medical bills for a work injury, at rates the state sets
- Part of the injured employee's lost wages
- The employer too: covered employees generally can't sue over the injury
Typically doesn’t
- Injuries outside work
- Independent contractors, in most states
- Lawsuits that get around the can't-sue trade-off — that's the employer's liability part of the same policy

Required in specific situations
Liability and property-damage protection for the vans and trucks that carry crews, casework, and trim stock to job sites.
Michigan's no-fault law sets default residual bodily injury liability limits of $250,000 per person and $500,000 per accident on every auto policy, though a driver may sign a state form to select limits as low as $50,000 per person and $100,000 per accident, and every policy must also carry at least $10,000 of property damage liability, which applies to damage caused in another state.
Required if the business puts owned or leased vehicles on public roads — nearly every state requires auto-liability coverage to operate them.
Commercial auto insurance includes liability and property-damage protection for cars, trucks, and vans used for business — for a finish-carpentry contractor, the vans that carry crews, cabinets, trim stock, and tools to customer job sites. Installation work happens at the customer's site — crews, casework, and material move to a different premises every day.
Typically covers
- Liability when a business vehicle injures someone or damages property
- Accidents in vehicles titled to the business, driven by employees for work
- The liability minimums states set for business vehicles
Typically doesn’t
- Your liability when employees drive their own cars for work — that's hired and non-owned auto; the employee's own car stays on their personal policy
- The freight or goods being hauled — that's cargo or inland marine coverage
- Damage to your own vehicle, unless physical damage coverage is added

A licensing financial guarantee — not insurance for the business — some states require on file before issuing the license.
Michigan licenses carpentry businesses statewide through LARA's Bureau of Construction Codes — residential construction, repair, or alteration work of $600 or more requires a Residential Builder or Residential Maintenance & Alteration Contractor license carrying the carpentry trade (MCL 339.2401–2404; examination plus 60 hours of approved prelicensure education), and no surety bond attaches to the license, while commercial-only carpentry needs no state credential.
Required if your state's (or city's) licensing law conditions the carpentry or contractor license on filing a surety bond — the license won't issue or renew without it.
A contractor license bond is a financial-guarantee instrument the contractor buys from a surety and files with the licensing authority; it protects the public, not the contractor. Where a state conditions the carpentry or contractor license on one, it must be on file before the license will issue or renew — which states require one, and in what amounts, is set state by state by the licensing law. Where the licensing board demands it, the bond is a gate on the license itself — a contractor in a bond state cannot legally operate without one on file.
Typically covers
- Customers or the state, if you break the licensing board's rules
- The licensing requirement itself — where a board demands a bond, no bond often means no license
Typically doesn’t
- You — the surety collects any payout back from you
- Injuries or property damage from your work — that's general liability
- Big-job performance disputes — a performance bond is its own instrument

Worth a look for this trade
Third-party injury and property damage — at the job site during the install, and after close-out when installed work fails.
Protects the business against claims of bodily injury, property damage, and personal injury — the customer's floor or countertop a crew damages mid-install is the working-hours half. Its products/completed-operations section pays for damage that occurs away from your premises and is caused by your completed work — the defining finish-carpentry exposure, since installed cabinetry, trim, and stairs stay in the customer's building long after the job closes. A finish carpenter's biggest exposure survives the job: a cabinet run, stair rail, or trim install that fails later is a claim that arrives after the crew has left.
Typically covers
- Injuries to customers, visitors, and other third parties
- Damage your operations cause to someone else's property
- Legal defense for covered claims
Typically doesn’t
- Your employees' injuries — that's workers' compensation
- Mistakes in professional advice or design — that's professional liability
- Redoing your own faulty workmanship itself

Inland-marine coverage for the table saws, routers, and nail guns that live in the van and on job sites.
Inland marine insures movable business property — contractor equipment and property in transit — wherever the work is. For a finish carpenter that means the table saws, miter saws, routers, and nail guns riding in the van and set up on customer job sites rather than at a fixed premises. The trade's capital is its tools, and they ride in the van between job sites — inland marine is the property line built to follow them.
Typically covers
- Tools and equipment that travel — in trucks, on job sites, between locations
- Theft from a vehicle or job site, a common loss
- Rented or borrowed gear, when it's listed on the policy
Typically doesn’t
- Gradual wear and breakdown
- Tools that stay at your shop — that's commercial property
- The vehicles themselves
