Construction Insurance: The Complete 2026 Guide

Construction carries some of the highest insurance costs of any commercial industry, and the math is straightforward: high-hazard work, high-value projects, and high claim severity. The Associated General Contractors of America reports the industry employs more than 8 million workers across over 919,000 firms nationally. For a contractor, the coverage stack is rarely just GL and WC. This guide outlines the seven coverages most construction operations need, what underwriters care about most, and how class codes and project size drive premium.

The Core Coverages a Construction Operation Needs

Every general contractor or trade contractor needs the following at minimum. Larger operations or specific project types layer on more.

• General Liability. Standard ISO CG 00 01 occurrence form. Construction GL prices on payroll or revenue depending on carrier and class. The most expensive exclusions for contractors are subsidence, professional services, and (for residential) the Your Work and Products-Completed Operations carve-outs.
• Workers' Compensation. WC is the largest premium line for most contractors. Rates run from under $2 per $100 of payroll for finish carpentry (NCCI 5437) to over $20 per $100 of payroll for roofing (NCCI 5551) and ironwork. Class code selection is the single largest premium driver after EMR.
• Commercial Auto. Contractor fleets carry a full ISO CA 00 01 BAP with hired and non-owned coverage. Vehicles over 10,001 lbs GVWR cross into FMCSA territory and may require MCS-90 endorsements.
• Inland Marine. Covers tools, equipment, materials in transit, and installation floaters. Heavy equipment over $25K typically goes on a scheduled contractor's equipment policy.
• Builder's Risk. Course-of-construction property coverage for the project itself. Usually written project-by-project on ISO CP forms or carrier-specific manuscript forms.
• Umbrella and Excess Liability. Most GCs carry $5M to $25M in excess limits. Project owners and lenders routinely require $5M minimums on commercial builds.
• Contractors Pollution Liability (CPL). Excavation, demolition, and any work disturbing soil or existing structures benefits from CPL. Standard GL excludes pollution.

These seven lines anchor most contractor programs. Project owners, lenders, and bidding requirements frequently push contractors into higher limits and additional endorsements, which is where building a construction insurance program by trade and project type matters most.

How Class Codes Drive Workers' Comp Premium

Construction WC is where insurance costs swing the most.

• Class code selection. NCCI publishes more than 50 construction class codes. The correct code depends on actual work performed, not company name. Misclassification is the most common audit dispute on construction accounts.
• Subcontractor payroll. If a sub does not carry their own WC certificate, their payroll usually becomes part of yours at the contractor's class rate. AGC and contractor associations recommend collecting certificates of insurance and additional insured endorsements at every job.
• EMR and project bidding. Most public projects and large private owners require a mod factor at or below 1.00. A 1.25 mod can disqualify a contractor from federal and DOT work regardless of price.

The Risks Underwriters Care About Most

Construction underwriters focus on a short list of exposures.

• The OSHA Fatal Four. Falls, struck-by, caught-in-between, and electrocution account for the majority of construction fatalities tracked by OSHA. Carriers credit fall protection programs, competent person designations, and pre-task planning.
• Subcontractor controls. Single largest GL claim driver. Underwriters want to see written subcontractor agreements, COI tracking, and additional insured endorsements with primary and non-contributory wording.
• Residential versus commercial work. Residential exposure carries higher GL severity from construction defect claims. Carriers often exclude condos, apartments, or tract residential outright.
• Wrap-up programs. Owner-controlled (OCIP) and contractor-controlled (CCIP) insurance programs change how individual policies respond. The contractor's own GL and WC must coordinate with the wrap, not duplicate it.

What Construction Insurance Typically Costs

Premium varies sharply by trade and state. As a rough benchmark, total cost of insurance for a $5M revenue general contractor often runs 3% to 8% of revenue, with WC making up half or more. Travelers construction industry reporting has flagged auto severity, subcontractor defaults, and rising medical costs on WC claims as the leading loss drivers heading into 2026.

How TruPoint Approaches Construction Insurance

TruPoint reviews construction submissions on actual scope of work, payroll distribution by class, subcontractor controls, and three-year loss runs. The team validates class codes against the work performed rather than industry assumptions, flags missing endorsements before bind, and structures programs that hold up at audit. Submissions move through a single underwriter from intake to issuance. See more about TruPoint's artisan and construction program.
