What Is Inland Marine (Tools & Equipment) Insurance?
Inland marine insurance is the coverage type that protects portable property that moves — tools, equipment, and materials that travel between job sites, shops, vehicles, and storage yards. For contractors, it's commonly called "tools and equipment insurance" or "contractor's equipment coverage." Despite the name, it has nothing to do with water. The term dates back to early marine insurance policies that were extended to cover goods transported overland.
For California trade contractors, inland marine is an essential coverage that fills the gap left by your other policies. Your general liability covers damage you cause to others — not your own property. Your commercial auto covers your vehicles — not the tools inside them. Your workers' comp covers injured employees — not your equipment. Inland marine is the coverage that protects your investment in the tools and equipment that make your business run.
What Tools & Equipment Insurance Covers
A contractor's inland marine policy covers your tools, equipment, and materials against direct physical loss, subject to policy exclusions. Here's what's typically covered:
- Theft — Tools and equipment stolen from job sites, vehicles, trailers, or your shop are covered. This includes overnight theft from an unsecured job site or a break-in to your work van.
- Fire and Smoke Damage — If a job site fire destroys your equipment or tools stored at the location, inland marine responds.
- Vandalism — Deliberate damage to your tools or equipment at a job site or storage location.
- Accidental Damage — Many policies cover accidental physical damage to equipment — dropping a laser level off a scaffold, or a generator damaged when a vehicle backs into it.
- Transit Coverage — Equipment and materials in transit — on a truck, trailer, or even shipped by freight — is covered during transport.
- Materials and Supplies — Many policies extend to cover materials you've purchased for a job before they're installed. Copper pipe, wire, lumber, and tile stored at the job site can be covered.
What Tools & Equipment Insurance Does NOT Cover
Understanding the exclusions in your inland marine policy is important to avoid surprise claim denials:
- Wear and Tear — Gradual deterioration, rust, corrosion, and normal wear are not covered. Insurance covers sudden, accidental losses — not the gradual aging of equipment.
- Mechanical Breakdown — If a piece of equipment fails due to a mechanical or electrical fault (not external damage), it's generally not covered. This is a maintenance issue.
- Mysterious Disappearance — If equipment simply goes missing with no evidence of theft (no broken locks, no witnesses, no police report), many policies won't pay. Document everything.
- Employee Dishonesty — Theft by your own employees is typically excluded from inland marine policies. This is covered under a separate crime or employee dishonesty policy.
- Damage to Others' Property — If your equipment damages someone else's property, that's a general liability claim, not an inland marine claim. GL and inland marine work together — not interchangeably.
Important Distinction: General liability covers damage TO others from your work. Inland marine / tools & equipment covers damage TO your own property. You need both. Many contractors discover this gap only after suffering a claim.
Blanket vs. Scheduled Equipment Coverage
When setting up your inland marine policy, you'll choose between blanket coverage, scheduled coverage, or a combination of both:
Blanket Coverage
A single dollar limit (e.g., $25,000 or $50,000) applies to all your tools and equipment combined. You don't list every item. Blanket coverage is simpler to manage, works well for contractors with many smaller tools, and doesn't require updating the policy every time you buy a new drill or circular saw. The tradeoff is that the blanket limit must be high enough to cover your worst-case total loss scenario.
Scheduled Coverage
Each significant piece of equipment is listed on the policy with its own value and coverage. Scheduled coverage is ideal for high-value individual items — a $12,000 pipe fusion machine, a $25,000 skid steer, or a $8,000 laser level system — where you want to ensure full replacement coverage regardless of the blanket limit. Items over $2,500–$5,000 are commonly scheduled.
Combined Approach
Most contractors with significant tool and equipment investments use a combination: a blanket limit for hand tools and small power tools, with key high-value items scheduled separately. This provides clean, comprehensive coverage without requiring you to itemize every socket set and extension cord.
Real Claim Scenarios: What Inland Marine Actually Pays
A San Diego electrical contractor parks his service van at a tract home job site over a long weekend. Monday morning, he discovers the van was broken into and $18,000 in electrical tools — Milwaukee power tools, wire pullers, conduit benders, and test equipment — have been stolen. His commercial auto policy covers the smashed van window ($400). His inland marine policy covers the stolen tools at replacement cost, minus his $1,000 deductible: $17,000 paid.
✓ Covered by Inland Marine — TheftA concrete contractor in Riverside County has a portable generator — valued at $8,500 — stored at an active job site. An overnight job site fire (caused by another contractor's equipment) destroys the generator along with some materials. The fire was not the concrete contractor's fault. The inland marine policy covers the generator at replacement cost, minus the $500 deductible: $8,000 paid.
✓ Covered by Inland Marine — FireAn HVAC contractor is transporting a large commercial compressor unit on a flatbed trailer. During transport on a Southern California freeway, the trailer hits a significant pothole and the compressor shifts, falls, and sustains $4,200 in damage that requires replacement of internal components. The inland marine policy's transit coverage responds, paying $3,700 after the $500 deductible.
✓ Covered by Inland Marine — Transit DamageTools & Equipment Insurance Pricing
Inland marine premiums are based primarily on the total insured value of your tools and equipment, your deductible, and to a lesser extent your claims history and trade. Here are typical annual cost ranges:
| Total Equipment Value | Typical Annual Premium | Recommended Deductible |
|---|---|---|
| Under $10,000 | $300 – $600 | $500 |
| $10,000 – $25,000 | $500 – $1,200 | $500 – $1,000 |
| $25,000 – $75,000 | $900 – $2,200 | $1,000 |
| $75,000 – $200,000 | $1,800 – $4,500 | $1,000 – $2,500 |
| $200,000+ | Custom pricing | $2,500+ |
Items with individual values over $5,000 are typically scheduled separately, which may change the premium calculation. High-value specialty equipment (bore machines, directional drills, excavators, telescoping booms) is priced individually.
Replacement Cost vs. Actual Cash Value: Make sure your inland marine policy pays on a replacement cost basis, not actual cash value (ACV). ACV deducts depreciation — a 4-year-old $5,000 generator might only get you $1,800 ACV. Replacement cost pays what it costs to replace the item today. Always opt for replacement cost coverage.
