What is inland marine insurance?
Inland marine insurance covers business property that moves or sits away from your main location, such as tools on a job site, equipment in a truck, or goods in transit. It typically picks up where a standard commercial property policy leaves off. That form usually offers only a small limit for property away from the described premises, and often nothing at all once the property is in a vehicle.
Despite the name, inland marine is not boat insurance; the name is a leftover from the ocean cargo policies that first followed goods ashore. It covers business property that moves, tools on a job site, equipment in a truck, goods in transit, or valuable items that standard property coverage leaves behind once they leave your premises.
What does inland marine cover?
What does Inland Marine Insurance cover?
- Tools and equipment away from your primary location.
- Contractors’ equipment on job sites.
- Property in transit between locations.
- Goods held at a third-party site or on consignment.
- Specialized items like cameras, medical devices, or fine art, depending on the policy.
- An installation floater, which follows materials a contractor is installing from the point the form says coverage attaches until the owner accepts the work, filling the seam before builders risk or property coverage takes over.
- Valuation is worth checking. Many forms settle at actual cash value rather than replacement cost, and scheduled items can sometimes be written on an agreed value.
Why does property leaving the building matter?
California businesses that travel between job sites and cities, common given the state’s geography, frequently have significant property exposure on the road that a standard property policy does not follow. Inland marine helps close that gap.
Which businesses need it?
Contractors, tradespeople, photographers, medical and dental providers, delivery and installation businesses, and anyone whose valuable property regularly leaves the building. Where your commercial property policy gives only a small limit away from the premises, inland marine picks up from there.

Inland marine insurance in California, explained
What is inland marine insurance, and why is it called that?
It is property insurance for things that move or sit away from your premises, and the name is a fossil. Ocean marine insurers wrote the first policies on cargo, then followed the cargo ashore, and the class kept the word. Insurance Code section 100 lists marine as one of California's classes of insurance. Section 103 defines it to reach goods and property in transit or transportation on land, property awaiting shipment, and all personal property floater risks. The list of what an inland marine policy may cover is a regulation: Title 10, sections 2320 to 2322 of the California Code of Regulations, in force since 1954. It is California's version of the Nationwide Marine Definition the insurance commissioners adopted in 1933. The Department of Insurance's plain summary is that inland marine is a specialized type of property insurance covering business property in transport. Commercial vessels sit under ocean marine, and California even files pleasure-craft hull under inland marine, so "nothing to do with boats" is not quite right.
What does inland marine cover that my commercial property policy does not?
Property away from the described premises. The property form insures your building, your business personal property and the property of others at the address on the declarations, and gives only a small extension for property in transit or at another location. Inland marine is written to follow the property wherever it goes: tools on a job site, equipment in a truck, goods in a customer's custody, a machine being installed in someone else's building. The Department of Insurance's commercial guide puts it as damage to or destruction of your business property while in transport, plus the liability exposure for property in your care, custody or control. The regulation also draws the line from the other side. Section 2322 bars a marine policy from covering your own merchandise in storage, goods in the course of manufacture on your premises, furniture and fixtures, and fire and windstorm on buildings. Those stay on the property policy.
What are the common inland marine floaters for a California business?
The Department of Insurance names the usual ones: accounts receivable, consignment, equipment floaters such as contractors' equipment, installation floaters, motor truck cargo, trip transit and valuable papers. The regulation's list adds physicians' and surgeons' instruments, fine arts for museums and businesses, electronic data processing equipment, bailee policies for cleaners and laundries, and property sold on installment or leased. Contractors' equipment is the mobile machinery floater in that list, written for property that has come into the hands of the people who use it. Motor vehicles designed for highway use are excluded from every version, which is why a licensed truck belongs on commercial auto. Our contractors' tools and equipment page covers scheduling tools and the theft conditions, and our cargo insurance page covers goods in transit for sale. This page is the class-level explainer that sits above both.
Is inland marine named perils or all risks, and what is usually excluded?
Commonly open perils, which means everything except what the form excludes. The Department of Insurance lists the perils an inland marine form may include as fire, lightning, windstorm, flood, earthquake, landslide, theft, collision, derailment, overturn of the transporting vehicle and bridge collapse. Note flood and earthquake on that list. They are commonly excluded on open-perils property forms, but on inland marine they are frequently included, sometimes with their own sublimit or deductible, so check each floater's declarations rather than assuming. The exclusions commonly found in the form are wear and tear, gradual deterioration, rust, mechanical or electrical breakdown, dishonest acts of the insured or employees, and unexplained disappearance or inventory shortage. The tools page lists the same ones for equipment; they do not need repeating here.
How are limits and valuation set on an inland marine policy?
By schedule or by blanket, and by the valuation clause. A scheduled floater lists each item with its own limit, which is why equipment is identified by serial number. A blanket limit applies to a class of unscheduled property up to a per-item cap. Valuation is the clause to read. The Department of Insurance's commercial guide says that unless the policy defines it, actual cash value in California means fair market value. The replacement-cost-less-depreciation measure many people quote is the fire-policy rule in Insurance Code section 2051, and floaters are carved out of the standard fire policy scheme by section 102. Agreed value pays the stated amount and waives coinsurance. Replacement cost pays for new property of like kind up to the limit. Some floaters carry a coinsurance clause, so scheduling equipment at its full value is what avoids the penalty, and the schedule needs updating when values change.
What is an installation floater, and when does the coverage end?
It insures a seller's or contractor's interest in the machinery, equipment and materials being installed in someone else's building, at the job site, in transit and in temporary storage awaiting installation. The Nationwide Marine Definition sets the end point: written for the owner, coverage ceases on completion and acceptance; written for a seller or contractor, it ends when that party's interest ceases. California's regulation describes installation risks as machinery and equipment, including plumbing, heating, cooling and electrical systems, while in transit to the place of installation and during installation and testing. The starting point is set by the form, not by the definition, so do not assume it attaches at the supplier's dock. Builders' risk is the other side of the same job: it insures the structure for the owner or general contractor for the project term, and the two policies should hand off at a defined point.
What is bailee coverage, and what does California law expect of a bailee?
Bailee coverage pays for customers' property in your custody, and California law is why you need it. Under Civil Code section 1852, a depositary for hire must use at least ordinary care for the thing deposited. Section 1840 caps a negligent depositary's liability at the value it was told or had reason to suppose. Section 1838 presumes gross negligence when the depositary cannot or will not explain how a loss happened. Section 1856 gives the depositary a lien for storage charges and insurance bought at the bailor's request. A cleaner, a repair shop, a furrier, a warehouse or a data recovery firm is a bailee every day. The form decides whether it pays only when you are legally liable or pays for the customer's property regardless of fault, and the second kind is what keeps the customer relationship intact after a fire.
Does contractors' equipment coverage satisfy a general contractor's insurance requirements?
Only the property part of them. No California statute requires a contractor to carry inland marine or equipment coverage. The Contractors State License Board requires the $25,000 license bond and workers' compensation with employees, and requires liability insurance only of limited liability company licensees under Business and Professions Code section 7071.19. General contractors and owners set their own terms in the subcontract, which usually name liability, workers' compensation and auto. Some add a property or equipment floater, with a waiver of subrogation or the general contractor as loss payee for rented or owner-furnished equipment. Equipment coverage answers that property clause; it does not stand in for the liability certificate. Read the subcontract's insurance article and send it with the quote request.
How is leased or rented equipment covered?
Read the rental agreement before the policy. California law makes a hirer liable only for damage caused by a lack of ordinary care, under Civil Code section 1928 and section 1929. Rental agreements commonly shift the whole risk of loss to the renter from pickup to return and add the owner's loss of rental income while the unit is out of service. An equipment floater can add a rented or leased equipment limit, and some forms add loss-of-use reimbursement for the owner's claim; the lessor may ask to be named as loss payee. Compare the agreement's damage clause with the floater's limit before signing. On theft, the CHP's 2025 report counts construction and farm equipment inside the 7.9 percent of vehicle thefts that are neither cars nor motorcycles, and calls such equipment a popular target for its resale value. Floaters commonly condition theft from a vehicle on the vehicle being locked and enclosed or attended, and the tools page explains that condition.
How do you get an inland marine quote from us?
Start a business insurance quote and tell us which floaters you need: equipment, installation, bailee, electronic data processing, fine arts, accounts receivable, valuable papers or transit. Send an equipment schedule with make, model, year, serial number and current value per item, any blanket limit for small tools, and whether the values are replacement cost or actual cash value. Add where the property goes, whether it sleeps in vehicles, and whether any of it leaves California. For installation work, the contract values, the systems installed, who owns the materials before acceptance, and whether the owner carries builders' risk. For bailee exposure, what you hold and the peak value on hand. Include rental agreements, the insurance article of any subcontract, prior losses and your current property, liability and auto declarations so the policies hand off at a defined point. Some floaters we can write directly and quickly. Others go to underwriting for approval, or need a wholesale market, and those take longer. Either way you know before you decide.
Statutory and regulatory references current as of September 2026 and specific to California. Form descriptions are general; the floater's own wording controls valuation, perils and conditions.
Goods in storage and parcels in transit, explained
Does my commercial property policy follow my inventory into a rented storage unit?
Usually not, and the reason is worth understanding. A commercial property form defines what it covers by location, not by ownership. Business personal property is covered in or on the described building, or within a short distance of it. Stock sitting in a unit across town was never inside that grant in the first place, so it is not a question of an exclusion applying. It is a question of the property being outside the description. That is the gap a floater is written to close.
Why does the off-premises extension usually miss a storage unit I already rent?
Because of how the extension is conditioned. A standard form's off-premises extension reaches three situations. The first is property temporarily at a location you do not own, lease or operate. The second is property in storage at a location you lease, where that lease began after the current policy term started. The third is a fair or trade show. A self-storage unit is leased, so the first condition fails. If you have rented that unit for years, the second fails as well. Many extensions are also switched off entirely unless the policy carries a coinsurance percentage of eighty percent or more. The extension is a small fixed amount even when it does apply, and it does not reach property in or on a vehicle.
If I store goods in someone else's warehouse, is the warehouse responsible for them?
Only for its own carelessness, and only up to a limit it is allowed to set. Under Commercial Code section 7204 a warehouse is liable for loss caused by its failure to exercise the care a reasonably careful person would use. The same section lets the storage agreement cap the damages, and lets the agreement set deadlines for presenting a claim. Section 7102 defines a warehouse as someone storing goods for hire who acknowledges possession and contracts to redeliver. So a fire with no negligence, or a negligent loss under a contractual cap, leaves you short. The warehouse promises care. It does not promise to make you whole.
Is a self-storage facility responsible in the same way?
No, and California says so directly. Business and Professions Code section 21701 provides that a self-service storage facility is not a warehouse. Self-service is the operative word. You keep the key and you never hand over possession, and Civil Code section 1814 makes giving possession the thing that creates a deposit. No possession and no document of title means no warehouse relationship and no bailment. The risk of loss sits with you as a matter of law, not merely as a matter of what the rental agreement says. Insure the contents yourself or accept the exposure.
Is the policy offered at the storage counter the same thing as a floater?
It is a different product sold under a restricted license, and the statute is unusually candid about its limits. California licenses self-service storage agents to sell hazard coverage on personal property in storage or in transit during the rental period. The facility must disclose that the cover may duplicate protection you already hold, and that the facility and its staff are not qualified or authorized to evaluate whether your existing insurance is adequate. That disclosure is the law's own description of what the counter can and cannot do for you. Read it against what your business actually has before deciding.
Are the goods mine, or am I holding them for someone else?
This is the question that decides which form you need, and both merged pages skipped it. If the property is yours, you insure it as your own property, and a transit or storage floater responds without anyone having to be at fault. If you are holding goods that belong to a customer, that is a liability exposure and it belongs on a bailee form. The two are not interchangeable, and the wrong one leaves the loss uninsured. Note also that a general liability policy answers neither. It excludes damage to property you own, rent or occupy, and it excludes personal property in your care, custody or control.
Does a shipping company's liability limit actually insure the parcels I send out?
The default figure is not insurance. It is a contractual ceiling on the shipping company's own liability, allowed by 49 U.S.C. section 14706, under which you are treated as having declared a low value in exchange for the published rate. Buying additional value above that default is a separate matter, and on some published terms those charges are passed to an insurer as premium on the shipper's behalf. So the honest statement is narrower than people expect. Nothing is automatically insured, the default is a liability cap rather than a policy, and anything above it is bought shipment by shipment on terms you do not set. Published terms also carry short notice deadlines and carve-outs, and inadequate packaging is the one that defeats most claims.
When does the risk of loss on an outbound order pass to my customer?
It depends on your own order terms, not on the shipping label. Commercial Code section 2509 passes the risk to the buyer when the goods are handed to the shipping company on a shipment contract, and only on tender at the destination on a destination contract. There is a practical layer above the legal one. A business that replaces every lost order as a matter of customer service carries the exposure whatever the code says. Insurance Code section 281 recognizes an insurable interest wherever a peril could directly damage you. If you routinely make customers whole, you are the one bearing the loss, and that is insurable.
Ready to look at it? Start a business insurance quote and tell us where the property actually sits. List each off-site location, whether you lease it and roughly when that lease started, and the value of what is held there. Tell us whether any of it belongs to a customer, what your average and maximum shipment values are, and whether you replace lost orders as a matter of policy. Household goods in storage are a personal lines question rather than a commercial one, so say if that is what you are asking about. Some accounts we can write directly and quickly. Others go to underwriting for approval, or need a wholesale market, and those take longer. Either way you know before you decide.
