Construction & Contractors insurance in Ohio.

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 Ohio 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 Ohio layer

Then Ohio adds its own rules.

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

OH factor #1
Monopolistic comp and the stop-gap question
Because comp comes from the state fund, it includes no employers liability coverage. Ohio employers need stop-gap employers liability added to their general liability policy, an endorsement that out-of-state programs routinely miss.
OH factor #2
Industrial property valuation drift
Legacy plants and warehouses across Ohio carry replacement-cost figures set years ago. Construction inflation plus ordinance-or-law triggers on older structures turn partial losses into out-of-pocket rebuilds when valuations lag.
OH factor #3
Freight-corridor auto exposure
Ohio's interstates carry some of the densest freight traffic in the nation. Fleet liability limits should reflect corridor exposure and the national venues that routes touch.

01Ohio is one of four monopolistic workers' compensation states. Coverage is purchased through the state Bureau of Workers' Compensation, not private carriers.
02State-fund comp excludes employers liability, so stop-gap coverage endorsed to the GL is required to close the gap.
03BWC offers group-rating and retrospective programs that materially change comp economics for qualifying employers. The program election deserves annual review.

ARIA · coverage stack

What a complete stack looks like for this class.

The lines ARIA recommends for a well-structured program in this industry, in the order they typically attach.

01Commercial General Liability w/ project-specific endorsementsTabletop layer. Contract-required endorsements (CG 20 10 04 13, CG 20 37 04 13) properly attached.
02Commercial Auto + Hired/Non-ownedMobile workforce, owned vehicles + employee personal vehicles used for work. Hired/non-owned closes the gap.
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.
05Umbrella / Excess LiabilityMost owner contracts require $5M–$10M umbrella above GL/Auto/WC. Standard practice across mid-market GCs.
06Pollution Liability (CPL)Even non-hazardous trades pick up pollution exposure from fuel spills, dewatering, mold. Stand-alone CPL is cheap insurance against an expensive surprise.
07Performance + Payment BondsSurety relationship, not insurance. But procured together for project access.
