Builder’s risk insurance is a specialized property policy that protects buildings, materials, and equipment during active construction or renovation — covering losses from fire, theft, vandalism, wind, and other named perils before a project reaches completion. For homeowners, landlords, and property managers overseeing any significant build or remodel in the USA, this coverage fills a critical gap that standard homeowners insurance does not address.
Without the right policy in place, a single weather event or theft incident can halt your project and leave you absorbing costs that run into tens of thousands of dollars.
This guide covers everything you need to know: what builder’s risk insurance is, what it covers, how much it costs, and how to choose the right policy for your project.
What Is Builder’s Risk Insurance?
Builder’s risk insurance is a type of property insurance designed specifically for structures under construction or undergoing major renovation. It activates the moment construction begins and remains in force until the project reaches substantial completion or the policy term expires.
Unlike a standard homeowners policy, which covers a finished, occupied dwelling, builder’s risk insurance is built around the unique risks of an active job site. Materials sitting on-site before installation, framing exposed to weather, and equipment stored overnight are all vulnerable in ways that a conventional policy does not account for.
The policy is typically written for a fixed term — most commonly 3, 6, or 12 months — and can be extended if a project runs over schedule. Coverage applies to the structure itself, materials on-site, and in many cases materials in transit to the job site.
Builder’s risk insurance is one of several coverage types that fall under the broader category of construction project insurance — our construction project insurance overview explains how each policy type fits together and which projects require what coverage.
How Builder’s Risk Insurance Works
A builder’s risk policy is structured around a coverage limit that reflects the completed value of the project — meaning the total cost of construction, including labor and materials, once finished. The insured party pays a premium based on that limit, the project type, location, and duration.
When a covered loss occurs — say, a fire destroys framing materials or a storm damages a partially completed roof — the policyholder files a claim. The insurer sends an adjuster to assess the damage, and the payout covers the cost to repair or replace what was lost, up to the policy limit.
Most policies are written on an “all-risk” or “open-peril” basis, meaning they cover all causes of loss except those specifically excluded. Common exclusions include earthquake, flood, employee theft, and mechanical breakdown, though many of these can be added through endorsements.
Who Needs Builder’s Risk Insurance?
Builder’s risk insurance is relevant to anyone with a financial interest in a structure under construction. That includes:
- Homeowners building a new home from the ground up
- Landlords adding a new unit or structure to an existing property
- Property managers overseeing commercial build-outs or tenant improvements
- Real estate investors undertaking major renovations before a sale or lease
- General contractors who are responsible for the project under their contract
The party who purchases the policy depends on the contract structure. In some cases the property owner buys it; in others the general contractor carries it. Either way, the policy should name all parties with a financial interest — owner, contractor, and lender — as additional insureds.
General contractors managing new builds or large renovations typically carry their own coverage, and understanding how their policy interacts with yours is essential — our general contractor insurance guide breaks down what contractors are required to carry and how it affects your project.
What Does Builder’s Risk Insurance Cover?
Builder’s risk insurance covers physical loss or damage to a structure and its components during the construction period. The scope of coverage depends on the policy form, but most standard policies share a common set of covered perils and property types.
Property and Materials Coverage
The core of any builder’s risk policy covers the structure being built and the materials associated with it. This typically includes:
- The building or structure under construction
- Foundations, framing, and permanent fixtures
- Materials and supplies stored on-site awaiting installation
- Materials in transit to the job site (up to a specified sublimit)
- Temporary structures such as scaffolding and construction trailers
Covered perils under a standard all-risk policy include fire, lightning, explosion, windstorm, hail, theft, vandalism, and water damage from sudden and accidental events. Each of these represents a real and common risk on an active construction site.
Knowing what your policy covers is only useful when you also understand the full scope of what a project costs — our home renovation costs guide provides realistic budget ranges for common renovation types so you can set your coverage amount accurately.
Soft Costs and Extended Coverage
Beyond the physical structure, many builder’s risk policies can be extended to cover soft costs — the indirect financial losses that result from a construction delay caused by a covered event. These include:
- Architect and engineering fees for redesign
- Permit re-application fees
- Additional loan interest during a delay
- Real estate taxes accrued during an extended construction period
- Lost rental income if the completed property was intended to generate revenue
Soft costs are frequently overlooked when setting coverage limits, but they can represent a significant portion of total project losses. Our dedicated soft cost coverage explains exactly which expenses qualify and how to document them for a claim.
What Builder’s Risk Insurance Does Not Cover
Understanding exclusions is just as important as understanding what is covered. Standard builder’s risk policies do not cover:
- Earthquake and flood: These require separate policies or endorsements. Flood coverage through the National Flood Insurance Program (NFIP) is available for qualifying properties.
- Employee theft or dishonesty: A crime policy or fidelity bond is needed for this exposure.
- Contractor errors and faulty workmanship: Defective work is not a covered peril. Correcting poor workmanship is the contractor’s responsibility.
- Tools and equipment owned by contractors: These are typically covered under a separate inland marine or equipment floater policy.
- Liability for bodily injury: General liability insurance covers this exposure, not builder’s risk.
- Existing structures: If you are renovating an existing building, the existing portions may not be covered unless specifically added by endorsement.
Reviewing exclusions carefully before binding coverage is one of the most important steps in the purchasing process. Ask your insurer specifically about flood, earthquake, and existing structure coverage if any of these apply to your project.
Types of Builder’s Risk Insurance Policies
Builder’s risk policies are not one-size-fits-all. The structure of the policy, the coverage form, and the available endorsements vary based on project type, duration, and the insurer’s offerings.
Completed Value vs. Reporting Form Policies
The two most common policy structures for builder’s risk insurance are the completed value form and the reporting form.
Completed value form: The coverage limit is set at the outset based on the projected completed value of the project. The premium is calculated on that full amount from day one. This is the most common structure for residential projects and straightforward commercial builds. It is simple to administer and ensures full coverage is in place from the start.
Reporting form: The policyholder reports the value of work in place at regular intervals — typically monthly — and the premium adjusts accordingly. This structure is more common on large, long-duration commercial projects where the insured value grows significantly over time. It can reduce upfront premium costs but requires diligent reporting to avoid coverage gaps.
Understanding how a completed value policy sets and adjusts limits throughout the build can prevent underinsurance at critical project stages.
Specialized Coverage Options
Beyond the standard policy forms, several endorsements and specialized coverage options are worth considering depending on your project:
- Flood endorsement: Adds flood coverage to a standard builder’s risk policy for projects in moderate-to-high flood zones.
- Earthquake endorsement: Available in seismically active regions; typically carries a separate, higher deductible.
- Existing structure coverage: Extends the policy to cover the portions of a building that existed before renovation began.
- Debris removal: Covers the cost of removing damaged materials after a covered loss, which can be substantial after a fire or storm.
- Ordinance or law coverage: Pays for the additional cost of rebuilding to current building codes when a covered loss requires reconstruction.
- Delay in completion: Covers lost income or additional expenses resulting from a project delay caused by a covered event.
Each endorsement adds to the premium but addresses a real exposure. The right combination depends on your project’s location, scope, and the financial consequences of a delay.
How Much Does Builder’s Risk Insurance Cost?
Builder’s risk insurance premiums are calculated as a percentage of the total insured value — typically the completed construction cost. For most residential projects in the USA, premiums fall in the range of 1% to 4% of the total project value annually, though this varies based on several factors.
Key Factors That Affect Your Premium
Several variables influence what you will pay for builder’s risk coverage:
- Project value: Higher construction costs mean higher premiums. A $500,000 custom home build will cost significantly more to insure than a $75,000 addition.
- Project type: New construction is generally less expensive to insure than renovation, because renovation projects carry additional risks related to existing structures and occupied adjacent spaces.
- Location: Projects in areas prone to severe weather, high crime, or seismic activity carry higher premiums. Coastal properties and flood-zone locations are particularly affected.
- Construction type: Wood-frame construction is considered higher risk than steel or masonry due to fire susceptibility.
- Project duration: Longer projects carry more exposure time and typically cost more to insure.
- Deductible: Choosing a higher deductible reduces your premium but increases your out-of-pocket cost in the event of a claim.
- Coverage extensions: Adding endorsements for flood, earthquake, soft costs, or existing structures increases the premium.
Premium calculations for builder’s risk policies share several variables with standard homeowners insurance, and understanding those shared insurance cost factors helps you anticipate how your project scope, location, and materials will affect your final rate.
How to Estimate Your Coverage Amount
Setting the right coverage limit is critical. Underinsuring your project means you will absorb a portion of any loss out of pocket. Overinsuring means you are paying for coverage you cannot collect.
The correct coverage amount is the total completed value of the project — meaning the full cost to build the structure from the ground up, including all labor, materials, and contractor fees. It does not include the value of the land.
For renovation projects, the coverage amount should reflect the total cost of the renovation work, plus the value of any existing structure being incorporated into the policy. If you are adding a $200,000 addition to a home, your builder’s risk limit should cover the full $200,000 in new construction costs.
Get detailed cost estimates from your contractor before binding coverage. If the project scope changes significantly during construction, notify your insurer and adjust the coverage limit accordingly.
How to Get Builder’s Risk Insurance
Builder’s risk insurance is available through most commercial property insurers, specialty construction insurance carriers, and independent insurance brokers. The purchasing process is straightforward but requires preparation.
What to Look for in a Policy
When comparing builder’s risk policies, focus on these key elements:
- Coverage form: Confirm whether the policy is all-risk or named-peril. All-risk provides broader protection.
- Covered property: Verify that materials in transit, temporary structures, and any existing structures are included if relevant to your project.
- Exclusions: Read the exclusions section carefully. Understand what is not covered and whether endorsements are available to fill those gaps.
- Sublimits: Many policies apply sublimits to specific categories such as theft, debris removal, or materials in transit. Make sure these sublimits are adequate for your project.
- Policy term and extension provisions: Confirm the policy term aligns with your project timeline and that extensions are available if needed.
- Claims process: Understand how to report a claim, what documentation is required, and what the typical response time looks like.

Questions to Ask Your Insurance Provider
Before binding a builder’s risk policy, ask your insurer or broker the following:
- Does this policy cover materials stored off-site or in transit?
- Is the existing structure covered if I am renovating?
- What is the process for extending the policy if my project runs over schedule?
- How are soft costs handled under this policy?
- What documentation do I need to file a claim?
- Are there any conditions I must meet to keep coverage in force — such as site security requirements or inspection schedules?
- Who should be named as additional insureds on the policy?
Getting clear answers to these questions before you purchase protects you from surprises when a claim actually occurs.
Builder’s Risk Insurance for Homeowners vs. Contractors
One of the most common points of confusion around builder’s risk insurance is who is responsible for purchasing it. The answer depends on the contract structure and the nature of the project.
Homeowner-Purchased Policies
When a homeowner hires a general contractor to manage a build or renovation, the homeowner often purchases the builder’s risk policy. This approach gives the owner direct control over the coverage terms and ensures the policy reflects the full project value.
Homeowner-purchased policies are common for:
- Custom home builds where the owner is acting as the project developer
- Major renovations where the owner has a significant financial stake in the outcome
- Projects where the lender requires the owner to carry builder’s risk as a condition of the construction loan
When a homeowner purchases the policy, the general contractor and any subcontractors with a financial interest in the project should be named as additional insureds.
Contractor-Purchased Policies
In many commercial and larger residential projects, the general contractor purchases the builder’s risk policy and includes the cost in the project budget. This is common when:
- The contractor manages multiple simultaneous projects and carries a blanket builder’s risk policy
- The contract specifically assigns insurance responsibility to the contractor
- The project involves a commercial property where the contractor has primary control of the site
When a contractor purchases the policy, the property owner and any lenders should be named as additional insureds to protect their financial interests.
Regardless of who purchases the policy, the contract should clearly specify who is responsible for builder’s risk coverage before work begins. Ambiguity on this point is one of the most common causes of coverage gaps on construction projects.
Many property owners assume their existing homeowners policy extends to active construction, but the gap between the two is significant — our homeowners vs. builder’s risk comparison details exactly where standard homeowners coverage ends and where builder’s risk must begin.
Builder’s Risk Insurance and Related Coverage Types
Builder’s risk insurance does not operate in isolation. A complete protection plan for any construction project involves several complementary coverage types, each addressing a different category of risk.
General Liability vs. Builder’s Risk
Builder’s risk and general liability insurance are frequently confused, but they cover entirely different exposures.
Builder’s risk covers physical damage to the structure and materials being built. It is property insurance for the project itself.
General liability covers bodily injury and property damage claims made by third parties — a visitor who trips on the job site, a neighbor whose fence is damaged by falling debris, or a subcontractor who is injured by unsafe conditions. It protects the policyholder from lawsuits and legal liability arising from the construction activity.
Both policies are typically required on any significant construction project. Builder’s risk and general liability insurance serve entirely different purposes on a job site, and carrying only one leaves critical gaps — that explains what bodily injury and property damage claims look like in practice and why both policies are typically required.
How Builder’s Risk Fits Into a Broader Coverage Plan
A complete coverage plan for a construction or renovation project typically includes:
- Builder’s risk insurance: Covers the structure and materials during construction
- General liability insurance: Covers third-party bodily injury and property damage claims
- Workers’ compensation insurance: Covers medical expenses and lost wages for workers injured on the job (required by law in most states)
- Contractor’s equipment insurance: Covers tools and equipment owned by the contractor
- Umbrella or excess liability: Provides additional limits above the general liability policy for catastrophic claims
Our property insurance guide maps out how builder’s risk, general liability, workers’ compensation, and umbrella policies work together to protect your investment across the full construction period.
Common Builder’s Risk Insurance Claims
Understanding the most common claim types helps you take preventive steps and respond effectively when a loss occurs.
Fire and explosion: Fire is one of the most severe risks on a construction site. Unfinished structures lack fire suppression systems, and combustible materials are often stored in close proximity. A single fire can result in a total loss.
Theft and vandalism: Construction sites are frequent targets for theft of materials, tools, and equipment. Copper wiring, lumber, and HVAC components are among the most commonly stolen items. Vandalism — including graffiti and deliberate damage — is also a significant exposure.
Wind and hail: Partially completed structures are highly vulnerable to wind damage. Roofing materials, framing, and temporary coverings can be destroyed in a single storm event.
Water intrusion: Water damage during active construction is one of the most frequently filed builder’s risk claims, and understanding what remediation involves helps you respond quickly — our water damage repair explains the full restoration process and what to expect from a professional crew.
Collapse: Structural collapse during construction can result from design errors, soil conditions, or unexpected loads. While faulty workmanship itself is excluded, the resulting damage to other covered property may be covered depending on the policy form.
How to File a Builder’s Risk Claim
When a covered loss occurs, act quickly and follow these steps:
- Secure the site to prevent further damage. Take reasonable steps to protect exposed materials and the structure from additional loss.
- Document everything before any cleanup or repairs begin. Photograph and video the damage from multiple angles. Record the date, time, and circumstances of the loss.
- Notify your insurer as soon as possible. Most policies require prompt notice of loss as a condition of coverage.
- Prepare a detailed inventory of damaged or destroyed materials, including quantities, unit costs, and supplier information.
- Cooperate with the adjuster during the inspection. Provide all requested documentation and answer questions accurately.
- Keep records of all expenses incurred to prevent further damage or to maintain the project timeline during the claims process.
Filing a successful claim depends heavily on the quality of your documentation from the moment damage occurs — our damage documentation checklist gives you a step-by-step record-keeping framework that insurance adjusters expect to see.
Builder’s Risk Insurance for Renovation Projects
Renovation projects present a distinct set of insurance challenges that differ from new construction. When you are working on an existing occupied or partially occupied structure, the risks are more complex and the coverage requirements are more nuanced.
When Existing Homeowners Insurance Is Not Enough
Standard homeowners insurance is designed for finished, occupied dwellings. When a major renovation begins, several coverage gaps emerge:
- Vacancy clauses: Many homeowners policies reduce or eliminate coverage when a home is unoccupied for more than 30 to 60 consecutive days. Major renovations often require the home to be vacated.
- Construction activity exclusions: Some homeowners policies exclude losses that occur during or as a result of construction activity.
- Increased value not covered: If your renovation adds significant value to the structure, your existing coverage limit may be inadequate to cover a total loss.
- Materials not covered: Homeowners policies typically do not cover building materials stored on-site before installation.
For any renovation project with a total cost exceeding $10,000 to $15,000, it is worth consulting with your insurance provider to determine whether your existing policy provides adequate coverage or whether a builder’s risk policy is needed.
Roof replacement and major structural work are among the most common triggers for coverage gaps under standard homeowners policies — our roofing replacement guide explains what a full roof project involves, what it costs, and why active construction requires dedicated coverage.
