Construction & Contractors insurance in Michigan.

Construction is the most contract-driven industry in commercial insurance. Every project agreement, every subcontract, every owner-issued spec carries insurance requirements. And the coverage must satisfy them or risk being kicked off the job. The line that surprises CFOs is wrap-up vs practice. Getting the structure wrong leaves either the owner or the contractor exposed.

Below is that profile under Michigan rules: Midwest perils, state statutes, and the market structure built around them.

ARIA · Construction & Contractors exposures

What ARIA flags first in this industry.

The exposures that hit this class hardest, drawn from analysis of mid-market accounts. The structural ones cost more than the premium-driven ones.

Risk #1
Additional insured language drift
Most owner contracts require CG 20 10 04 13 or equivalent AI on a primary, non-contributory basis. Standard blanket AI endorsements often don't satisfy this. The contract gets bid, work proceeds, then a claim reveals the gap.
Risk #2
Excluded work classes
Roofing, demolition, residential. Many CGL forms exclude or sublimit specific operations. A general contractor that picks up a small demo subcontract can void coverage on the whole policy if it crosses the exclusion.
Risk #3
Equipment + tools off-premises
Owned and leased equipment moves between jobsites continuously. Inland marine coverage with adequate per-tool limits and theft conditions is constantly out-of-sync with the actual equipment on the truck.

The Michigan layer

Then Michigan adds its own rules.

The perils and statutes that change how construction & contractors coverage must be structured here, before any quote means anything.

MI factor #1
Supplier contractual cascade
OEM purchase orders flow indemnity, recall, and insurance requirements down through every tier. A tier-2 supplier's coverage gets tested against terms written for tier-1 balance sheets, and recall expense is the line that breaks first.
MI factor #2
No-fault auto structure
Michigan's personal-injury-protection regime, even post-reform, makes commercial auto structure distinctive. Fleet programs imported from other states need Michigan-specific PIP and liability decisions.
MI factor #3
Production interruption concentration
Just-in-time supply means a single press failure or fire stops customer lines within days, with contractual penalties following. Business income and contingent BI need limits set against the customer's downtime math, not just your own.

01Workers' compensation is required for most employers. The threshold rules count employees in ways that capture nearly all real businesses, so assume it applies.
02Michigan auto insurance operates under a no-fault framework with PIP choices introduced by the 2019 reform. Commercial fleet decisions here are state-specific.

03Inland Marine (Contractors Equipment)Per-job and per-tool limits; theft, transit, mechanical breakdown. Scheduled vs blanket depending on equipment value.
04Workers' Comp w/ subcontractor compliance coverageSub-WC certificates required from every subcontractor; non-compliance results in audit-period exposure on the GC's policy.The MI layerWorkers' compensation is required for most employers. The threshold rules count employees in ways that capture nearly all real businesses, so assume it applies.
