Inland marine and contractors' equipment insurance for Massachusetts businesses.

What inland marine insurance covers for Massachusetts contractors

Inland marine insurance is the property line built for things that don’t stay in one place. Unlike ocean marine insurance, which covers goods transported over water, inland marine covers products, materials, and equipment moved over land, by truck or rail, or held temporarily by a third party such as a warehouse. The two most common causes of loss under inland marine policies are collisions and cargo theft, which tells you something about what the coverage is designed to respond to: property in transit, not property sitting still.

This matters because a standard Business Owners Policy (BOP) or Commercial Package Policy (CPP), covered in more depth in our Massachusetts commercial property insurance guide, generally covers property at a specific address. Some BOP and CPP forms extend limited coverage to tools and equipment that travel with employees to nearby job sites, so the first step before buying anything new is confirming exactly what your existing policy already picks up off-premises. Inland marine fills what’s left: equipment, materials, and specialty property that regularly leaves the shop, including construction and contracting equipment, computers, networking gear, medical and scientific instruments, and photography equipment. A related form, Bailee’s Customer Coverage, protects a client’s property while it’s in your care, which matters for repair shops, cleaners, and any business that temporarily holds someone else’s belongings.

Contractors equipment floaters vs. tools and equipment floaters

Contractors don’t usually need one policy for their equipment; they need two kinds of coverage that work differently.

A contractors equipment floater insures movable equipment not meant to travel on public highways: cranes, cement mixers, engines, and power drills fall into this category. Because this equipment isn’t licensed for the road, it also falls outside your commercial auto policy, and a personal auto policy is unlikely to help either, since those policies generally exclude vehicles used primarily for business. That’s a separate gap from equipment coverage entirely, and it’s worth reviewing alongside your commercial auto lineup, which we cover in the Massachusetts commercial auto insurance guide.

A tools and equipment floater, by contrast, covers insured property wherever it’s used: hand tools, power drills, hoisting machines, and power pumps are typical examples. The distinction is less about value and more about mobility and how the equipment is deployed day to day. Because construction risk carries its own set of exposures, an agent experienced with construction accounts can often package property and liability coverages, including endorsements like Owners and Contractors Protective Liability, which protects an owner or general contractor from liability arising from a subcontractor’s negligent acts, into a single program built for a small construction firm rather than forcing you to assemble it piecemeal.

How Massachusetts regulates inland marine rates under Chapter 174A

Massachusetts General Laws Chapter 174A governs rate regulation for fire, marine, and inland marine insurance. Most property lines under this chapter require a rate filing with the commissioner at least 15 days before the proposed effective date, and the commissioner can delay that effective date by up to 30 additional days to examine the filing or hold a hearing.

Inland marine risks are treated differently. Section 6(e) exempts inland marine contracts and policies from that standard prior-filing requirement when filings aren’t otherwise required for that risk. In practice, this carve-out is part of why inland marine forms and pricing tend to be more flexible and more customized to the individual account than standard property lines, where every rate change runs through the formal filing process. Chapter 174A also sets teeth behind its rules: Section 17 imposes a fine of not more than $500 for each willful violation, on top of any other penalty the law provides. Section 4 of the chapter also excludes motor vehicle insurance, aircraft hull insurance, and marine builders’ risk and protection and indemnity insurance from this rate-regulation framework entirely; those are treated as separate categories.

Builders risk insurance in Massachusetts: how it works on an active job

Builders risk insurance solves a problem no other property policy handles well: a building under construction has a value that keeps climbing as more of it gets built. A replacement-value builders risk policy is structured around that fact. If a tornado destroys a building that’s half-finished, the policy covers half of what the building would have been worth completed; if the building is three-quarters finished, the policy covers three-quarters of the completed value.

Massachusetts General Laws c. 175, §98 defines builders risk policies as those insuring against loss to buildings in the course of construction, and it requires every applicant for fire insurance on a building, which includes builders risk coverage, to complete a commissioner-prescribed application form. That form is required before the policy is first issued, whenever the named insured or mortgagee changes, and whenever coverage increases by more than 25%. Notably, MPIUA’s own building fire application lists builders risk policies as one of the categories exempted from having to accompany that §98 form, which is worth knowing if a lender or municipality asks why your builders risk submission looks different from a standard fire application.

Mass.gov’s construction-finance materials describe construction insurance, also known as builders risk insurance, as covering a building and its materials while under construction, and note that premiums for this coverage run higher than commercial property insurance on a completed building. If voluntary-market coverage isn’t available for a particular project, MPIUA, the Massachusetts FAIR Plan, provides basic property insurance as a market of last resort, with rates reviewed and approved by the Division of Insurance.

Licensing and workers’ compensation issues that intersect with equipment coverage

Equipment and builders risk decisions don’t happen in isolation from Massachusetts licensing rules. Contractors soliciting, bidding on, or performing work on an existing, owner-occupied property with one to four units must register as a Home Improvement Contractor (HIC). That registration alone covers ordinary repairs, such as exterior painting or repairing existing decking, but larger projects like building a deck or an addition require a Construction Supervisor License (CSL); the two credentials aren’t interchangeable. Certain projects also require oversight by a licensed construction supervisor or a registered design professional under 780 CMR, Chapter 1, subject to a homeowner exemption.

On the crew side, Massachusetts General Laws c. 152 requires employers to carry workers’ compensation insurance for all employees, regardless of the hours worked, apart from a narrow exception for domestic employees under 16 hours a week. LLC members, LLP partners, and sole proprietors of unincorporated businesses can exempt themselves personally, and corporate officers owning at least 25% of the company can request an exemption too, but none of that reaches their employees, including anyone operating scheduled equipment. The Department of Industrial Accidents can issue a stop work order against employers who lack coverage, and workers’ comp rates and classification codes come from the Workers’ Compensation Rating and Inspection Bureau of Massachusetts and the Division of Insurance, not the DIA itself. Our workers’ compensation guide walks through the mechanics in more detail.

Building the right equipment and builders risk program for your business

Start by confirming what your BOP or CPP already covers off-premises before adding a floater on top of it; duplicate coverage is wasted premium. From there, separate your equipment into what stays off the highway, which belongs on a contractors equipment floater, and what travels with crews day to day, which is a tools and equipment floater’s job. If you’re starting a construction project, line up builders risk coverage before breaking ground and revisit the c. 175, §98 application if coverage later increases by more than 25% or the named insured changes. Confirm licensing status under the HIC or CSL framework for the scope of work involved, and verify that workers’ compensation coverage under c. 152 extends to every equipment operator on the crew, not just the owners. A broker working across Property & Casualty and Workers’ Compensation lines can coordinate these policies so gaps don’t open up between them at renewal.
