A contractor is three months into a $1.8 million commercial build when a storm rips through the job site, destroys the framing, and saturates $200,000 worth of materials stacked on the ground. Without builder’s risk insurance, that loss comes directly out of someone’s pocket. With it, the policy responds, materials are replaced, and the project recovers.
That is the difference this coverage makes, and it is why anyone with money invested in a construction project needs to understand exactly how it works.
Builder’s risk insurance (also called course of construction insurance) is one of those policies that sounds straightforward until you need to file a claim.
The coverage triggers, exclusions, valuation methods, and policy periods are more nuanced than most people realize.
This guide covers everything you need to know: what builder’s risk insurance is, who needs it, what it covers and excludes, how much it costs, how to choose the right policy, and how it fits within a broader construction risk management strategy.
What Is Builder’s Risk Insurance?
Builder’s risk insurance is a specialized form of property insurance designed to cover buildings and structures while they are under construction or renovation. It protects the physical structure, the materials and supplies on site, and in many cases, materials in transit to the site. The policy is temporary by design. Coverage begins when construction starts (or when the policy is bound) and ends when the project is completed, the building is occupied, or the policy term expires, whichever comes first.
Standard commercial property insurance does not cover buildings under construction because those policies are designed for completed, occupied structures. Builder’s risk fills the gap between groundbreaking and certificate of occupancy.
Once the building is finished and operational, the owner transitions to a standard property insurance policy. Think of builder’s risk as the insurance that protects your investment during the most vulnerable phase of a building’s life, when it is an open construction site exposed to weather, theft, fire, and dozens of other hazards.
The policy is typically written on an “all-risk” (also called “special form”) basis, meaning it covers all causes of loss except those specifically excluded.
This is an important distinction from “named peril” policies, which only cover losses from perils explicitly listed in the policy. All-risk coverage is broader and more protective, but understanding what is excluded is just as important as understanding what is covered.
Who Needs Builder’s Risk Insurance?
The short answer: anyone with a financial interest in a construction project. That typically includes the property owner (who has the most to lose if the project is damaged or destroyed), the general contractor (who is responsible for delivering the finished project and may be contractually required to carry the coverage), and lenders and financial institutions (who are financing the project and want assurance that their collateral is protected).
Subcontractors, architects, and engineers may also be named as additional insureds on the policy, depending on the contract terms. In practice, the question of who purchases the policy is usually settled in the construction contract.
On many projects, the owner purchases the policy and names the contractor and subcontractors as additional insureds. On other projects, the general contractor purchases the coverage and includes the owner. The arrangement depends on the contract structure, the relative bargaining power of the parties, and industry practice in the region.
Even homeowners undertaking major renovations or new custom home construction should consider builder’s risk coverage. Standard homeowners insurance policies often exclude or severely limit coverage for properties under significant construction.
If a fire destroys your half-finished home addition, your homeowners policy may not respond. A builder’s risk policy will. For background on how pre-construction risk assessment fits into the planning process, see our dedicated guide.
What Builder’s Risk Insurance Covers
A well-structured builder’s risk policy covers the full range of physical loss or damage to the insured project during construction. Here is what a typical policy includes.
The Structure Under Construction
This is the core coverage. It protects the building or structure being constructed, including foundations, framing, roofing, interior finishes, and all permanently installed components. Coverage applies from the moment construction begins through completion.
Materials, Equipment, and Supplies
Construction materials stored on the job site (lumber, steel, concrete, fixtures, electrical components) are covered against theft, fire, vandalism, and other covered perils.
Many policies also cover materials in transit from the supplier to the site and materials stored at temporary off-site locations, though sub-limits may apply.
This coverage is particularly important because job sites are inherently vulnerable. Materials are often left in open areas, exposed to weather and accessible to thieves, especially during evenings and weekends when the site is unattended.
Temporary Structures
Scaffolding, temporary fencing, construction trailers, and formwork may be covered under the policy. Some policies include these automatically; others require a specific endorsement.
Soft Costs
Soft cost coverage addresses the indirect financial consequences of a covered loss that delays the project.
These can include additional interest on construction loans, extended real estate taxes and insurance premiums during the delay period, architectural and engineering fees to redesign damaged portions, additional rental expenses or lost rental income, and permit reapplication fees.
Soft cost coverage is not standard on every builder’s risk policy. It is typically added by endorsement and can be critical for projects where a delay of even a few months translates into significant financial exposure.
Debris Removal
After a covered loss, the cost of cleaning up and removing damaged materials from the site can be substantial. Debris removal coverage pays for this, subject to a sub-limit in most policies. This is an often-overlooked coverage that becomes very important after events like fires, windstorms, or structural collapses.
What Builder’s Risk Insurance Does Not Cover
Understanding exclusions is just as important as understanding what is covered. Common exclusions include the following.
Earthquake and flood. Most standard builder’s risk policies exclude earthquake and flood damage.
If your project is in a seismically active area or a FEMA-designated flood zone, you will need to purchase separate earthquake and flood endorsements or standalone policies. These endorsements add cost but are essential for projects in exposed locations. In coastal areas of Florida, Texas, and the Carolinas, wind and named-storm coverage may also be excluded from the base policy and require a separate endorsement.
Faulty workmanship and defective materials. Builder’s risk covers the resulting damage from defective work but generally does not cover the cost of redoing the defective work itself.
For example, if a plumbing subcontractor installs a defective pipe and it bursts, the policy will typically cover the water damage to other building components, but it will not pay to replace the defective pipe. The cost of correcting defective work is considered a construction cost, not an insurable loss.
Employee theft. Internal theft by employees of the insured may be excluded. Coverage for employee dishonesty typically requires a separate crime or fidelity bond.
War, terrorism, nuclear hazard. Standard exclusions in most property insurance forms, including builder’s risk.
Normal wear, mechanical breakdown, and design errors. The policy covers sudden and accidental losses, not gradual deterioration, normal settling, or losses caused by design defects. Professional liability (errors and omissions) insurance covers design professionals for errors in their work.
Existing structures (unless endorsed). If the project involves renovation of an existing building, the existing structure may not be covered unless the policy specifically includes it. This is a common gap on renovation projects and must be addressed during policy placement.

How Much Does Builder’s Risk Insurance Cost?
Builder’s risk premiums are calculated as a percentage of the total completed value of the project, typically between 1% and 5% of total hard construction costs. The median cost for small business customers is approximately $105 per month, according to Insureon. However, cost varies dramatically depending on several factors.
Total project value. The insured value is based on the total completed value of the project, including materials and labor (hard costs).
Land value is not included because land cannot be destroyed. A $250,000 residential renovation will cost considerably less to insure than a $10 million commercial build. Typical annual premiums range from $1,000 to $5,000 for smaller projects and can reach tens of thousands for large commercial developments.
Project type. New construction is generally less expensive to insure than renovation, because renovation involves existing structures with hidden conditions (outdated wiring, structural weaknesses, asbestos) that increase risk. Installation projects (such as HVAC or elevator installation) are typically the least expensive because they are shorter-duration and lower-complexity.
Construction type and materials. Fire-resistant construction (concrete, steel, masonry) costs less to insure than wood-frame construction because the fire risk is lower.
According to Embroker, rates can vary up to 50% depending on the construction classification, making it critical to provide accurate information about materials when obtaining quotes.
Location. Proximity to fire stations (lower risk, lower premiums), flood zones (higher risk, higher premiums or exclusion), coastal hurricane zones (significantly higher premiums), and high-crime areas (higher theft risk) all affect pricing.
A wood-frame project in a Florida coastal zone will cost dramatically more than an identical project in a low-risk inland area.
Project duration. Longer projects mean more time exposed to risk, which increases the premium. A six-month renovation presents less risk than an 18-month ground-up commercial build.
Deductible. Higher deductibles reduce premiums. Most policies offer deductibles ranging from $1,000 to $25,000 or more. Choosing a higher deductible is a straightforward way to manage premium cost, provided you can absorb the deductible amount in the event of a loss.
Coverage extensions and endorsements. Adding flood, earthquake, soft costs, pollution cleanup, green building, or other endorsements increases the premium but broadens protection. The right endorsements depend on the specific risk profile of your project.
Builder’s Risk Insurance vs. Other Construction Insurance
Builder’s risk is one component of a comprehensive construction insurance program. Understanding how it relates to other coverages prevents gaps and eliminates confusion.
General liability insurance covers third-party bodily injury and property damage claims arising from construction operations. If a visitor is injured on the job site, general liability responds. It does not cover damage to the project itself. That is the job of builder’s risk.
Workers’ compensation insurance covers employees who are injured on the job. It is mandatory in virtually every U.S. state and covers medical expenses, lost wages, and disability benefits. It does not cover damage to the building or materials.
Commercial property insurance covers completed, occupied buildings. It does not cover buildings under construction. Builder’s risk fills the gap between construction start and project completion.
Inland marine / contractor’s equipment insurance covers tools, equipment, and mobile property that the contractor moves from site to site. Builder’s risk covers the building and its permanent components. If you have expensive portable tools and equipment, you may need both.
Professional liability (errors and omissions) covers design professionals (architects, engineers) for errors in their professional services. Builder’s risk does not cover design defects.
Environmental / pollution liability covers cleanup costs and third-party claims arising from pollution events during construction. Builder’s risk may exclude pollution-related losses, making this a separate coverage to consider on projects involving hazardous materials or environmentally sensitive sites.
A comprehensive construction insurance program combines all of these coverages into an integrated package. No single policy covers everything. For a broader view of how insurance fits within construction risk management, see our guide on key risk indicators in the construction industry.
How to Choose the Right Builder’s Risk Policy
Selecting the right policy is not just about finding the lowest premium. It is about matching coverage to your project’s specific risks. Here is what to focus on.
Work with a specialized broker. Builder’s risk is a specialty product. Work with an insurance broker or agent who has specific experience in construction insurance. A generalist agent may not understand the nuances of coverage triggers, valuation methods, and endorsement options that matter on a construction project.
Understand when coverage begins and ends. Policies define inception and expiration differently. Some begin on a specific date; others begin when materials arrive on site or when construction starts.
Coverage typically ends at the earliest of project completion, occupancy of the building, policy expiration, or a specified number of days after completion. If your project runs long (which many do), you may need to extend the policy. Understand the extension process and cost before you need it.
Verify the valuation method. Most builder’s risk policies use a “completed value” approach, where the full project value is insured from day one, even though only a fraction has been built.
This is preferable because it eliminates the risk of being underinsured as the project progresses. The alternative, “reporting form” policies, require periodic reporting of values as construction progresses. These are less common and create administrative burden and potential coverage gaps if reporting is late.
Review exclusions carefully. Read the policy exclusions before you buy, not after a loss. Pay particular attention to earthquake, flood, wind/named storm, faulty workmanship, and existing structure exclusions. If your project faces any of these exposures, discuss endorsement options with your broker.
Check the carrier’s financial strength. Review the insurance carrier’s financial strength ratings from AM Best, S&P, or Moody’s. A financially stable carrier is more likely to pay claims promptly and remain solvent through a large loss. According to ConstructionCoverage.com, top-rated carriers for builder’s risk include Nationwide (A+ AM Best), State Farm (A++ AM Best), and The Hartford (A+ AM Best).
Assess claims handling reputation. Ask your broker about the carrier’s claims process. How quickly do they respond? Do they use in-house adjusters or third parties? What is their reputation for coverage disputes? A great policy with a poor claims process is a bad deal.
Filing a Builder’s Risk Claim
When a covered loss occurs, the claims process generally follows these steps. First, secure the site and prevent further damage.
This is a policy requirement: you must take reasonable steps to protect undamaged property and prevent additional loss. Second, notify your insurance carrier and broker immediately.
Delayed notification can complicate or even jeopardize a claim. Third, document everything. Photograph and video the damage before cleanup begins. Preserve damaged materials if possible.
Maintain detailed records of all costs incurred. Fourth, cooperate with the adjuster. The carrier will assign a claims adjuster to investigate the loss, assess the damage, and determine the covered amount. Provide all requested documentation promptly. Fifth, track your soft costs. If the loss causes a project delay, track all incremental costs (additional loan interest, extended insurance premiums, rental losses) that may be covered under a soft cost endorsement.
The most common reasons for claim disputes are underinsurance (the policy limit is below the actual project value), late notification, failure to mitigate further damage, and disputes over whether the loss was caused by a covered peril or an excluded event (such as faulty workmanship). Working with an experienced broker and reviewing your policy thoroughly before a loss occurs are the best defenses against these problems.
Builder’s Risk Insurance: 2025 Market Trends
The builder’s risk insurance market in 2025 is stabilizing after several years of rate increases driven by catastrophic weather losses and rising construction costs.
According to ConstructionPlacements.com, increased insurer capacity (more carriers willing to write this coverage) has helped keep rates relatively flat in many areas. However, several trends are worth watching.
Rising construction costs affect valuation. Material and labor costs have increased significantly over the past several years.
This means projects must be insured at higher values, which increases premiums even if rates per hundred dollars of coverage remain stable. Underinsurance is a growing concern. Some carriers now include automatic escalation clauses that adjust coverage limits upward to account for construction cost inflation.
Catastrophe-prone regions face capacity constraints. In Florida, the Gulf Coast, and wildfire-prone areas of the western U.S., some carriers have reduced their exposure or exited the market entirely.
Securing builder’s risk coverage in these regions may require quota-share arrangements (multiple carriers splitting the risk) or surplus lines placement. Start the insurance process early if your project is in a catastrophe-exposed area.
Green building endorsements are growing. As sustainable construction expands, more carriers offer endorsements that cover the additional cost to rebuild to green standards (LEED certification, energy-efficient materials) after a covered loss. If you are building a certified green project, ask about this coverage.
Technology-driven risk management. Some carriers now offer risk engineering services, weather alert systems, and drone-based site inspections as part of their builder’s risk programs.
These services reduce loss frequency and can lead to premium credits. Embracing technology-driven risk management is increasingly important. For more on how technology supports risk mitigation in project management, see our practitioner’s guide.
Practical Steps: Getting Builder’s Risk Coverage for Your Project
Here is a straightforward process for securing the right policy.
Step 1: Define your project scope. Gather the total project value (hard costs), project timeline, construction type and materials, location details, and a description of the work (new construction, renovation, or installation).
Step 2: Identify your exposures. Consider which risks apply: flood, earthquake, wind, theft, soft costs, existing structure damage, pollution, materials in transit. This will determine which endorsements you need.
Step 3: Engage a specialized broker. Provide your project details and exposure analysis. Your broker will approach multiple carriers to obtain competitive quotes.
Step 4: Compare policies, not just premiums. Evaluate the coverage form (all-risk vs. named peril), exclusions, sub-limits, deductibles, valuation method, extension options, and the carrier’s claims reputation. The cheapest policy is not always the best policy.
Step 5: Bind coverage before construction starts. Ensure the policy is in force before any work begins on site. Coordinate with your lender, who will likely require evidence of builder’s risk coverage before funding disbursements.
Step 6: Review and update during construction. If the project scope changes, costs increase, or the timeline extends, notify your broker and adjust the policy accordingly. An outdated policy creates gaps.

The Bottom Line
Builder’s risk insurance is not a luxury. For any project of meaningful value, it is a financial necessity. The cost of a policy is a fraction of the cost of an uninsured loss.
A single fire, a theft of materials, or a catastrophic weather event can set a project back by months and cost hundreds of thousands of dollars. The right policy absorbs that blow, keeps the project moving, and protects every stakeholder’s financial interest.
The key is getting the right coverage, not just any coverage. Work with a specialized broker. Read the exclusions. Match the policy to your project’s specific risks. And review it regularly as the project evolves. Construction is inherently uncertain. Builder’s risk insurance is one of the few tools that converts that uncertainty into something manageable.
