Builders risk is property insurance on the work itself while it is being built: the structure, materials on site and often materials in storage or transit, written for the completed value of the project. The contract usually decides who buys it, and the standard AIA owner-contractor exhibit places it on the owner unless the parties move it to the contractor. Whether a given loss is paid typically turns on the declared values, the insured interests named and the form's conditions on occupancy, testing, water, flood, earthquake, theft and delay.

## Key Decision Points
- Read the owner-contractor agreement first; it decides who buys builders risk and who absorbs the deductible.
- Declare completed value with owner-furnished equipment included and keep it current through change orders.
- Name every party whose money is in the work: owner, GC, subcontractors and the lender as loss payee.
- Existing structures, soft costs, delay and testing are separate decisions, not automatic features.
- Partial occupancy and permission to occupy usually need the insurer's written agreement before anyone moves in.

## What Builders Risk Insures During the Course of Construction

Builders risk is a first-party property policy written for one project and one construction period. It responds, subject to its terms, to direct physical loss or damage to the work in progress: framing lost to fire, a roof deck torn off by wind, installed equipment stolen before turnover. It is not liability insurance. Injury to a neighbor or damage to adjoining property is a project liability question, and the two policies are designed to sit beside each other rather than overlap.

Most project forms are written on a completed value basis. The limit is set at the value the project will have when finished, and the insurer accepts that the value at risk climbs from near zero at mobilization to the full figure at substantial completion. A reporting form is the alternative, where values are declared periodically as they rise. Completed value is common on new construction because it is simpler to administer, but it depends on an accurate starting number.

The policy period should match the construction schedule rather than a calendar year. Coverage commonly ends at the earliest of the policy expiration, acceptance by the owner, occupancy beyond what the policy allows or the point when the owner's permanent property insurance takes over. Those end triggers deserve as much attention as the start date, because a gap between builders risk ending and permanent property beginning is a familiar source of uninsured loss.

The exposure changes at each stage of the job; see [how project risk shifts from mobilization to turnover](https://mycontractorsinsurancequote.com/resources/project-risks-by-construction-phase).

## Who Should Buy It: Owner or Contractor

Start with the contract, not the market. In the AIA 2017 family, the Insurance and Bonds Exhibit attached to the owner-contractor agreement (A101-2017 Exhibit A) has the owner purchase builders risk on an all-risks completed value or equivalent form for the full project value on a replacement cost basis, unless the parties check the box that moves the obligation to the contractor. The same exhibit makes the owner responsible for losses within the deductible and points to the A201 general conditions for adjusting the loss, with the owner acting as trustee of the proceeds unless the parties set it differently.

Many contracts are not AIA forms, and many AIA forms are modified. Developers with a portfolio often prefer to control builders risk so they choose the insurer, the deductible and the claim relationship, and so the lender's requirements are satisfied directly. General contractors on smaller or design-build work sometimes buy it because they are better placed to manage values and schedule. Either approach can work. The failure point is a contract that assigns the duty to one party while the other party buys the policy, or both assume the other did.

When the owner buys, the GC should still read the policy before mobilization. The contractor's own materials, its subcontractors' stored property and its deductible exposure under the contract all depend on wording the contractor did not negotiate. When the GC buys, the owner should confirm the owner and lender appear with the correct interests and that cancellation notice reaches them.

For the owner-side view of these choices, read [insurance decisions developers control before construction](https://mycontractorsinsurancequote.com/who-we-serve/developers-subdividers).

### Illustrative scenario: A Houston-Area Tilt-Wall Distribution Center and the Hurricane Deductible

A developer is building a tilt-wall distribution center in Harris County, Texas, with completion planned for the Gulf hurricane season. The lender's term sheet asks for builders risk at full completed value with named windstorm and flood included. The first quote excludes flood because part of the truck court sits in a mapped special flood hazard area, and it applies a percentage named storm deductible measured against total insured value. The GC's contract, an AIA form, says the owner's policy may not exclude flood or windstorm. Before signing, the developer and GC agree to a contract modification stating the named storm deductible and a flood sublimit, the lender accepts it in writing and the GC prices its own deductible share into the guaranteed maximum price. Without the modification, a storm loss would have opened an argument over who absorbed the gap.

## Values and Insured Interests: Owner, GC, Subcontractors and Lender

**Who Typically Insures What on an Active Project**

| Property at risk | Policy that typically responds | What to confirm |
| --- | --- | --- |
| The building and permanent materials installed in it | Builders risk, often bought by the owner or GC with subcontractors of every tier as insureds for their interest | The declared value includes owner-furnished items and owner-direct trade packages |
| Materials stored off-site or in transit | A builders risk extension, typically with its own sublimit | The sublimit against the largest single shipment or storage location, and whether the location must be scheduled |
| A subcontractor's own tools and equipment | That subcontractor's contractors equipment or inland marine policy, which most builders risk forms leave out | The subcontract requires the trade to carry it and to waive subrogation |
| Rented or leased equipment | The renter's contractors equipment policy with rented equipment coverage, or a damage waiver bought from the rental company | What the rental agreement makes the renter responsible for |
| Temporary works such as scaffolding and formwork | Varies: some builders risk forms include temporary works, while others leave them to the contractor's equipment policy | The definition of covered property in the actual form |
| An existing building being renovated | Often the owner's property policy, unless the builders risk form adds existing structures by endorsement | That the two policies do not both exclude the existing structure |

Coverage depends on the actual forms, endorsements and contract terms. It varies by carrier guidelines, programs and individual risk, subject to terms.

The value declared drives both the limit and the premium, and an understated value can reduce what a claim pays under some forms. Hard costs are the base: the contract sum plus change orders, plus labor and materials supplied by others. The AIA exhibit sets the floor at the initial contract sum plus later modifications and work supplied by others. Owner-furnished equipment, owner-direct trade packages and site improvements are where values go missing, because they never pass through the GC's contract.

A project policy commonly names the owner as first named insured and includes the contractor, subcontractors of every tier and sometimes suppliers as additional insureds for their interest in the work. The AIA exhibit calls for exactly that set of interests plus mortgagees as loss payees. Including the trades matters because the insurer, once it pays the owner, generally cannot pursue a party that is itself insured under the same policy, and most construction contracts also include a waiver of subrogation for property losses.

The construction lender is typically added through a mortgagee or lender loss payable clause so it receives proceeds and notice. Loan documents frequently specify the exact clause, the notice period and the evidence form. Matching those requirements before closing avoids last-minute endorsements and a delayed first draw.

## Existing Structures and Renovation Work

Renovation and addition projects raise a question new construction does not: who insures the building that was already standing? Many builders risk forms exclude existing property unless it is scheduled, and the owner's permanent property policy may restrict coverage while the building is vacant or under major renovation. The AIA exhibit addresses this directly by requiring the owner to carry separate all-risks replacement cost insurance on the existing structure through the correction period.

The practical answer usually depends on how much of the building stays in use. An occupied office being re-tenanted floor by floor may keep the owner's property policy in force with a renovation endorsement, while builders risk insures the new work only. A gut rehabilitation of a vacant warehouse may justify a builders risk form that schedules the existing shell as a separate value. Either way, the underwriter will want to know what share of the finished value is new versus existing.

Fire protection is the underwriting focus on renovation work. Federal construction safety rules require existing sprinkler systems to be kept in service as long as reasonable during demolition and alteration, with control valves operated only by authorized persons and checked at the end of each workday. A written impairment procedure and a hot work permit system can affect both acceptance and terms.

Scheduling the existing building, vacancy conditions and occupied-space work are covered in more depth on our page about [builders risk for renovations and existing structures](https://mycontractorsinsurancequote.com/builders-risk-insurance/renovations-and-existing-structures).

## Off-Site Storage and Transit

A large share of value can sit away from the jobsite for months: curtain wall panels at a fabricator, switchgear in a bonded warehouse, precast elements at a casting yard. Builders risk forms often include off-site storage and transit as extensions with their own sublimits, which may be a small fraction of the main limit. The AIA exhibit lists storage and transit coverage as a separate item the contractor may be required to buy, which signals how often it falls outside the base policy.

Ask for the storage and transit sublimits in writing and compare them with the highest single-location value expected during the job. Ask whether the storage location must be scheduled, whether storage at a supplier's plant qualifies and whether property is insured once title passes to the owner or only once it is delivered. Purchase orders and supply agreements often set when risk of loss transfers, and that clause should line up with the policy.

Long-lead electrical and mechanical equipment raises these questions most sharply; see [builders risk for industrial and data center equipment](https://mycontractorsinsurancequote.com/builders-risk-insurance/industrial-and-data-center-projects).

## Partial Occupancy and Permission to Occupy

Builders risk is priced for an unoccupied construction site. Once tenants, residents or owner operations move into part of the project, the risk changes. Many forms limit or end coverage on the occupied portion. The AIA exhibit bars owner occupancy or use of any completed or partially completed portion before substantial completion until the insurer consents in writing to continuing coverage.

Phased projects are the common case: a multifamily building opening floors in sequence, a retail center turning over pads to tenants or a campus energizing its first building while the second is framed. Ask the insurer for a permission to occupy endorsement that names the occupied area and confirms whether builders risk continues on it, or whether the owner's permanent property policy picks it up. The answer should be in writing before the certificate of occupancy for the first phase.

Phased openings are routine on housing work; see [phased residential and multifamily project insurance](https://mycontractorsinsurancequote.com/projects/residential-construction).

## Soft Costs and Delay in Completion

A fire that destroys a third of a building also pushes the opening date. The repair cost is a hard-cost claim. The extra loan interest, the extended architect and consultant fees, the added real estate taxes and the lost rent during the delay are soft costs and delay losses, and most base builders risk forms do not include them unless the extension is purchased. The AIA exhibit lists soft costs and delay in completion as optional coverages the owner selects, naming items such as construction loan fees, leasing and marketing expenses, additional professional fees and carrying costs.

Delay coverage is commonly triggered only by a physically damaging loss that would itself be insured, and it applies after a waiting period measured in days. The limit, the waiting period and the indemnity period are separate decisions, and each should be tied to the lender's pro forma and the project schedule. Expediting expense and extra expense coverages may help pay to compress the repair schedule, and ordinance or law coverage addresses code upgrades required during rebuilding.

Liquidated damages make this a contractor issue too; read [project insurance for general contractors](https://mycontractorsinsurancequote.com/who-we-serve/general-contractors).

## Testing and Commissioning

Damage during testing is one of the most negotiated parts of a builders risk form. The AIA exhibit calls for coverage for building systems damaged in testing and startup, but many market forms limit testing coverage to a set period, exclude hot testing or testing of machinery under load or end coverage on any system once it has been accepted. Mechanical and electrical systems on hospitals, labs, plants and data centers make this more than a footnote.

Before binding, give the underwriter the commissioning plan: which systems are tested, in what sequence, by whom, with what fuel or process load and for how long. Ask whether cold testing and hot testing are treated differently, whether the testing period has a day limit and whether resulting damage to other property is insured when a component fails during a test. Write down the answers; the commissioning schedule often slips past the period a quote assumed.

How testing limits, catastrophe sublimits and deductibles feed the premium is explained in [what drives builders risk cost and deductibles](https://mycontractorsinsurancequote.com/builders-risk-insurance/cost).

## Common Exclusions and Sublimits to Read Closely

Water damage is a leading source of builders risk claims on wood-frame and interior-finish work. Many forms now apply a separate, higher water damage deductible or require a written water mitigation plan, with leak detection and shutoff procedures, as a condition. Ask whether the condition is a warranty that could void coverage if not followed, or a deductible change.

Named storm, flood and earth movement are typically sublimited or carry percentage deductibles, especially in coastal Texas and seismically active California. The AIA exhibit lists flood, earthquake and windstorm among the perils the owner's policy should not exclude, so a quote with those perils excluded or sublimited may not satisfy the contract as written without an agreed modification. FEMA's Flood Map Service Center is the official source for the effective flood zone that the underwriter will check.

Theft of materials and installed copper can be limited by security conditions, such as fencing, lighting or monitoring requirements. Defect exclusions vary widely: some forms exclude the defective part and any resulting damage, while others pay resulting damage and exclude only the cost of correcting the defect itself. Those clauses decide most disputed claims, so ask for the actual wording rather than a summary.

Damage to third parties falls to the liability side; see [project-specific liability alongside builders risk](https://mycontractorsinsurancequote.com/project-specific-liability-insurance).

## Rebuilds in Wildfire and Flood Hazard Areas

Rebuilding after a wildfire or flood raises builders risk questions that an ordinary project may not. Some carriers limit or decline the fire peril in high fire hazard areas, wildland-urban interface construction can raise replacement values and earth movement and flood are commonly excluded or sublimited unless endorsed. Availability and terms vary by carrier and program, so they are confirmed for each address before the contract is signed.

Those questions are explained in [builders risk for wildfire rebuild projects](https://mycontractorsinsurancequote.com/builders-risk-insurance/wildfire-zone-rebuilds).

## Contract Wording to Check Before Signing

The owner-contractor agreement, the loan agreement and any subcontract all contain property insurance language, and it rarely matches without editing. Check who buys the policy, the deductible each party bears, whether the contractor must carry builders risk on its own scope if the owner's policy does not respond and the mutual waiver of subrogation for property losses. A waiver limited to proceeds paid differs from a broad waiver.

Then check the perils the contract says may not be excluded, any sublimits schedule, the start and end of coverage, the occupancy provisions and the cyber or data-loss carve-outs that newer forms raise. Each of these should be compared with the actual quote. Where the policy cannot match the contract, document an agreed change before signing rather than after a loss. A licensed broker and project counsel should review the final language.

On larger projects, builders risk is often coordinated with a wrap-up; see [owner- and contractor-controlled insurance programs](https://mycontractorsinsurancequote.com/wrap-up-insurance).

## Before You Ask for a Quote

### What to Gather
- Executed or draft owner-contractor agreement and its insurance exhibit
- Completed value broken into hard costs, owner-furnished equipment and site work
- Construction schedule with phase turnovers and commissioning dates
- Site address, construction type, stories and fire protection plan
- Lender's insurance requirements and loss payee wording
- Off-site storage locations and expected peak value at each

### What to Ask the Insurer or Surety
- Is the form completed value or reporting, and how are change orders added?
- What are the water damage, named storm, flood and earth movement deductibles and sublimits?
- What defects wording applies, and does resulting damage remain insured?
- How long does testing coverage last, and is hot testing included?
- What happens to coverage on any area occupied before substantial completion?
- Are soft costs and delay included, with what waiting period and indemnity period?

## Broker Notes

**Quick Answer:** Builders risk insures the project itself against physical loss while it is being built. The construction contract decides who buys it, and the AIA owner-contractor exhibit places it on the owner unless the parties assign it to the contractor.

**Common Mistake:** Declaring only the GC's contract sum and leaving out owner-furnished equipment, owner-direct work and site improvements. An understated value can shrink a claim payment and leave the most expensive items without a stated value.

**Broker Perspective:** A broker reads the contract's property insurance clause and the lender exhibit before requesting quotes, then checks that the occupancy, testing and peril terms in the quote can satisfy both.

**Coverage Impact:** Whether a loss is paid often depends on endorsements rather than the base form: water and storm deductibles, defect wording, testing limits and occupancy consent typically decide disputed claims.

## Questions Buyers Ask

### Does the owner or the general contractor usually buy builders risk on a commercial project?

It depends on the contract. The standard AIA 2017 owner-contractor exhibit has the owner buy it unless the parties check a box assigning it to the contractor. Developers often prefer to control the policy so they pick the insurer and satisfy the lender directly. Contractors sometimes buy it on smaller or design-build work. What matters most is that the contract and the actual policy agree on who bought it.

### Should the builders risk value be the construction contract amount or the full project cost?

Usually the full completed value of the insured work, which is often more than the GC's contract. Add change orders, owner-furnished equipment, owner-direct trade packages and site improvements the policy is meant to insure. Land is typically excluded. Soft costs such as loan interest are a separate limit if purchased. Review the value whenever a large change order or equipment purchase is approved.

### Can tenants move into finished floors while the rest of the building is still under construction?

Often yes, but not without the insurer's agreement. Many builders risk forms limit or end coverage on occupied areas, and the AIA exhibit requires written insurer consent before early occupancy. Ask for a permission to occupy endorsement that identifies the occupied area and states whether builders risk or the owner's permanent property policy insures it from that date.

### Will builders risk pay for extra loan interest if a fire delays opening?

Only if a soft cost or delay in completion extension was purchased, and then typically only when the delay comes from physical damage the policy itself insures. The extension usually has its own limit, a waiting period before payments start and a maximum indemnity period. Tie each figure to the lender's budget and the construction schedule when you buy it.

### Is the existing building included when we renovate or add on to it?

Not automatically. Many builders risk forms exclude existing structures unless they are scheduled with a separate value. The owner's permanent property policy may continue on the existing building, but it can carry vacancy or renovation restrictions. Decide which policy insures the existing structure before work starts and confirm it in writing with both insurers.
