📋 About Builder's Risk Insurance for Construction Projects ▾

Builder's risk insurance — sometimes called course-of-construction (COC) insurance — is a specialized property policy that protects a structure from the moment groundbreaking begins until the certificate of occupancy is issued. It sits under the broader umbrella of [commercial property insurance](https://contractorsplanet.com/?service=insurance&subcat=commercial-property-insurance), yet it functions very differently from a standard commercial or homeowner policy because the insured asset is incomplete, its value changes daily, and the roster of parties with a financial stake in it can number a dozen or more. Lenders almost universally require it — Fannie Mae, Freddie Mac, and most construction-loan underwriters mandate evidence of builder's risk coverage before the first draw is released — and general contractors who skip it expose owners, subs, and themselves to catastrophic out-of-pocket losses.

Q: Who is responsible for buying builder's risk insurance — the owner or the contractor?

Responsibility is determined by the construction contract, not by law. On most residential projects, the general contractor procures the policy and names the owner and lender as additional insureds or loss payees. On larger commercial projects, the owner often procures an owner-controlled insurance program (OCIP) that wraps all parties. The AIA A201 General Conditions document defaults to the owner as the procuring party, but many contractors modify that clause. Regardless of who buys it, confirm the arrangement in writing before breaking ground — coverage gaps caused by the 'I thought you had it' assumption are alarmingly common and rarely covered after a loss.

Q: Does builder's risk insurance cover subcontractor work and their materials?

Standard builder's risk policies cover the work in place and materials on-site regardless of which party installed or supplied them, provided those parties are either named insureds or the policy uses broad 'insured contract' language. However, some forms exclude damage caused by a subcontractor's faulty workmanship — meaning the defective work itself is excluded, but resulting damage to other parts of the structure may still be covered. Always read the 'faulty workmanship' exclusion carefully and ask your broker whether a resulting-damage carve-back is included. Subcontractors should also carry their own general liability and inland-marine tool coverage independently.

Builder’s Risk Insurance Hiring Guide

📖 Overview

The core peril set covered by a builder's risk policy typically mirrors that of an all-risk inland-marine form: fire, lightning, windstorm, hail, explosion, theft, vandalism, and collapse. Carriers such as Zurich, Travelers, Liberty Mutual, and Markel write the majority of U.S. builder's risk premium, and their policy language diverges in meaningful ways. Some use a "named perils" structure that lists only the hazards explicitly enumerated; others use an "open perils" or "special form" structure that covers everything not specifically excluded. Open-perils forms cost roughly 10–20 % more in premium but are almost always worth it on large jobs where the list of possible failure modes is long.

Coverage typically extends to materials stored on-site or in transit — a provision that matters enormously when $80,000 worth of HVAC equipment is sitting on a flatbed waiting for crane placement — as well as temporary structures, scaffolding, and, on enhanced endorsements, soft costs such as architect fees, permit re-issuance, and lost rental income caused by a covered delay. Flood and earthquake are almost always excluded from the base form and must be added by endorsement or through a separate DIC (difference-in-conditions) policy; in FEMA Special Flood Hazard Areas or California Seismic Zone D, omitting those endorsements is a serious underwriting gap.

[Residential new construction](https://contractorsplanet.com/?service=insurance&subcat=commercial-property-insurance&subsubcat=builders-risk-insurance&subsubsubcat=residential-new-construction) projects — single-family homes, spec builds, custom builds, and small multi-family up to four units — have their own risk profile and policy structures. Premiums on residential projects run lower per dollar of completed value than commercial work, but the coverage triggers, named insured arrangements, and lender-loss-payee clauses require careful attention, particularly when the homeowner, the builder, and a bank all have simultaneous insurable interests.

[Commercial construction](https://contractorsplanet.com/?service=insurance&subcat=commercial-property-insurance&subsubcat=builders-risk-insurance&subsubsubcat=commercial-construction) projects — office buildings, retail centers, warehouses, mixed-use towers, and industrial facilities — introduce a higher layer of complexity: wrap-up insurance programs (OCIPs and CCIPs), project-specific excess layers, business-income coverage for the future tenant, and environmental endorsements for sites with known contamination histories. A $50 million ground-up office project will typically carry a dedicated builder's risk tower, with the primary layer written by one carrier and excess layers placed through the London market or domestic surplus-lines insurers.

Premiums across both segments are typically quoted as a percentage of the completed project value — industry averages range from 0.15 % to 0.75 % of the total insured value (TIV) for a 12-month policy — but the actual rate depends on construction type (wood-frame vs. masonry vs. steel), occupancy class, project location, loss history of the contractor, and chosen deductible. A $500,000 wood-frame spec home in a Gulf Coast hurricane zone might carry an annualized premium of $4,500 to $6,000 with a $5,000 all-peril deductible and a separate 2 % wind/hail deductible, while a comparable project in inland Ohio could come in under $2,000. Always verify that the policy's reporting requirements are met — most forms require notice of substantial completion to avoid a coverage gap during the hand-off to a permanent property policy. When the project involves a [general contractor](https://contractorsplanet.com/?service=general-contractor), [remodeling](https://contractorsplanet.com/?service=remodeling), or [renovation](https://contractorsplanet.com/?service=renovation) firm, confirm at contract execution who is responsible for procuring the builder's risk policy, because gaps in that assignment are one of the most common and costliest coverage failures in construction.

✅ What it covers

Selecting a named-perils vs. open-perils (special form) policy structure with the appropriate carrier
Adding flood, earthquake, or windstorm endorsements based on project location and FEMA/seismic zone designations
Identifying all named insureds — owner, general contractor, subcontractors, and lender loss payees
Setting deductibles for all-peril, wind/hail, and theft sub-limits
Scheduling materials in transit and off-site storage locations
Establishing a reporting and premium-adjustment schedule for projects that extend beyond the initial policy term
Coordinating policy hand-off to a permanent commercial or homeowner property policy at certificate of occupancy
Reviewing exclusions for faulty workmanship, design error, mechanical breakdown, and subsidence

💵 Typical cost range

$800 to $75,000

Builder's risk premiums are quoted as a percentage of the total insured value (TIV), typically 0.15 %–0.75 % for a 12-month policy. A $300,000 wood-frame single-family home might cost $800–$2,200 annually in a low-risk inland market; the same project in a Florida coastal county with a hurricane deductible endorsement can reach $4,500–$6,000. Commercial projects scale accordingly — a $10 million warehouse might carry a $15,000–$40,000 annual premium, while a $100 million mixed-use tower can exceed $200,000 per year across primary and excess layers. Key cost drivers include construction type (wood-frame costs more than masonry or steel), project ZIP code, contractor loss history, chosen deductibles, and optional endorsements for flood, earthquake, soft costs, and delay in completion. Minimum premiums from most admitted carriers start around $800–$1,200 regardless of project size.

🛡️ Hiring tips

Verify the broker holds a valid P&C license in your state and has placed at least 10–15 builder's risk policies in the past 24 months — construction insurance is a specialty line and generalist agents frequently miss critical endorsements
Request an open-perils (special form) policy rather than a named-perils form unless budget constraints make it impossible; the broader coverage is worth the 10–20 % premium difference on any project over $150,000
Confirm the policy includes materials in transit and off-site storage, as theft from staging yards is among the most common builder's risk claims filed
Check that flood and earthquake coverage is addressed explicitly — either endorsed onto the policy or declined in writing after a conscious risk review, not simply ignored
Ask for a copy of the certificate of insurance with all lender loss payees listed before the first construction draw is released
Compare at least three carriers' forms side by side, not just premium quotes — Zurich, Travelers, Markel, and Intact/OneBeacon use materially different exclusion language
Ensure the policy has a completed-value reporting clause and understand the penalty for underreporting, which typically voids coverage proportionally under a coinsurance provision

More frequently asked questions

What's the difference between builder's risk and general liability insurance on a construction project?

Builder's risk is a property policy — it pays to repair or replace the structure and materials when a covered peril (fire, theft, wind, etc.) damages them during construction. General liability is a third-party liability policy — it pays for bodily injury or property damage that the contractor causes to others. The two coverages are complementary, not interchangeable. A fire that destroys framing is a builder's risk claim; a worker who falls through a subfloor and sues the GC is a general liability claim. Both are typically required by lenders and sophisticated project owners, and neither substitutes for workers' compensation, which is mandatory in nearly every state.

How is the total insured value (TIV) calculated for a builder's risk policy?

TIV should equal the completed replacement cost of the project — labor, materials, contractor overhead and profit, and any soft costs (permits, architect fees, engineering) included in the coverage form. It does not include land value. Underinsuring the TIV to reduce premium is a serious mistake: most builder's risk policies contain a coinsurance clause (typically 80–100 %) that penalizes proportionally any claim submitted when coverage is less than the required percentage of actual completed value. Update the TIV if the project scope expands after binding — most policies allow mid-term endorsements to increase limits without penalty.

Are renovation and remodeling projects eligible for builder's risk coverage?

Yes, though underwriters treat renovations differently than ground-up new construction. The key variable is whether the existing structure is occupied during construction. Occupied-renovation policies carry higher rates because the exposure includes not only the work in progress but also the existing building contents and the increased liability of workers alongside tenants. Unoccupied renovations are rated more favorably. Some carriers require a separate 'installation floater' for large MEP (mechanical, electrical, plumbing) equipment being retrofitted into an existing structure. Always disclose the renovation scope and occupancy status fully at application — misrepresentation on those points is a common basis for claim denial.

When does builder's risk coverage end, and how do I transition to a permanent property policy?

Builder's risk coverage typically terminates at the earliest of: the policy expiration date, the date the structure is occupied or put to its intended use, or the date the owner accepts the completed work. At that trigger point — usually certificate of occupancy issuance — you need a permanent commercial property policy or homeowner's policy already bound and effective. There is no grace period under most builder's risk forms; a fire the day after occupancy without a replacement policy in force is an uninsured loss. Coordinate the hand-off date with both your builder's risk carrier and your permanent insurer at least 30 days before anticipated completion.

Does builder's risk insurance cover theft of materials from the job site?

Most open-perils builder's risk policies cover theft of materials on-site, subject to a deductible and any applicable sub-limit. However, theft is one of the most heavily sub-limited perils — it's common to see a $25,000 or $50,000 theft sub-limit on a policy with a $2 million overall limit. Copper wiring, HVAC equipment, and appliances are the most frequently stolen items on residential sites. If your project involves high-value mechanical or electrical components, negotiate a higher theft sub-limit at binding rather than after a loss. Off-site storage locations must usually be scheduled on the policy to be covered; a warehouse across town is not automatically included under a site-specific form.

What happens if the construction project runs over its scheduled completion date?

Builder's risk policies are written for a defined term — typically 6, 12, or 24 months. If the project extends beyond that term, the policy must be renewed or extended before expiration; coverage does not automatically continue. Insurers may re-underwrite at renewal and adjust the premium based on the project's loss history and current market conditions. Notify your broker at least 60 days before policy expiration if there is any risk of delay — surprises at renewal result in either coverage gaps or last-minute surplus-lines placements at significantly higher rates. Some large commercial project policies include automatic extension endorsements of 30–90 days, but residential and small commercial forms rarely do.
