Michigan Excavation Contractor Insurance

MICHIGAN EXCAVATION REQUIREMENTS AT A GLANCE

HOW MUCH DOES EXCAVATION CONTRACTOR INSURANCE COST IN MICHIGAN?

Most Michigan excavation operations pay between $1,008 and $1,632 per month depending on coverage level, from a solo owner-operator’s basic bundle up to a fully crewed operation carrying property, cyber, and workers’ comp. General Liability alone averages $496 per month ($5,952 per year) in Michigan, according to MoneyGeek’s 2026 excavation insurance cost analysis, with Commercial Auto running notably higher than GL, a reflection of Michigan’s no-fault auto insurance environment.

A Starting bundle (General Liability + Commercial Auto) runs about $1,008/month for a solo operator getting road-legal and bid-eligible. Add a crew and equipment and a Comprehensive bundle (adding Workers’ Comp, Commercial Property, Inland Marine, and Cyber) runs closer to $1,632/month. What most often gets left off a Michigan contractor’s policy isn’t the core coverage, it’s Pollution Liability and adequate Excess/Umbrella limits, both priced separately and easy to skip until a claim proves why they mattered.

DOES MICHIGAN REQUIRE A CONTRACTOR LICENSE FOR EXCAVATION WORK?

Yes, for residential work. Michigan’s Maintenance & Alteration (M&A) Contractor license, issued by the Department of Licensing and Regulatory Affairs (LARA), explicitly lists excavation as one of the trades it covers, alongside work like concrete, masonry, and house wrecking. This license applies to residential construction. We could not verify a specific state bonding dollar amount tied to the license after checking LARA’s official pages directly, so confirm current bonding requirements with LARA’s Residential Builders section before you bid. Commercial and industrial excavation work isn’t clearly covered by a separate state license, so check with the municipality where you’re bidding larger non-residential jobs.

WHAT IS THE MICHIGAN 811 REQUIREMENT AND DOES IT APPLY TO ME?

Any excavation in Michigan falls under the MISS DIG Underground Facility Damage Prevention and Safety Act, Public Act 174 of 2013, enforced by the Michigan Public Service Commission. Before you dig, you’re required to notify MISS DIG 811, the state’s official one-call center, at least 3 business days in advance, so utility operators can mark buried lines. Skipping notification carries real financial exposure: civil penalties of up to $5,000 per violation, on top of whatever damage and liability claim follows the utility strike itself.

IS GENERAL LIABILITY INSURANCE LEGALLY REQUIRED IN MICHIGAN?

Not by state law, no. But in practice, it’s not optional. General contractors, property owners, and municipalities across Michigan routinely require proof of General Liability coverage, usually via a Certificate of Insurance, before you’re allowed on a site or awarded a bid, and it’s often expected alongside your M&A license paperwork. Because excavation carries elevated risk (utility strikes, cave-ins, subsidence), the limits requested often exceed what a generic contractor policy provides. That’s exactly the gap a policy built specifically for excavation work is designed to close.

DO I NEED WORKERS’ COMPENSATION INSURANCE IN MICHIGAN?

Yes, and it triggers fast. Under the Workers’ Disability Compensation Act, Michigan requires coverage for private employers regularly employing 3 or more employees at one time (including part-time), as well as employers with even a single employee working 35+ hours a week for 13 or more weeks in the prior year. Non-compliance carries real teeth: a fine of $1,000 and/or imprisonment of 30 days to 6 months, with each uninsured day treated as a separate offense. See the Michigan Workers’ Disability Compensation Agency for full requirements.

BUILT FOR MICHIGAN EXCAVATION AND GRADING CONTRACTORS

Between M&A licensing, MISS DIG 811 compliance, and a workers’ comp threshold that catches most crews almost immediately, Michigan contractors have more real state-level structure to navigate than states with no licensing at all. Excavation Insurance Group built this page so Michigan contractors can see exactly where that exposure sits, not just the sticker price on a policy. That’s where a full coverage review matters most: making sure your General Liability, Workers’ Comp, and Pollution Liability line up with what your GCs, municipalities, and licensing board will actually demand.
