How Much Does Builder's Risk Insurance Cost?

Builder's risk insurance cost is set by underwriting, not by a universal formula. Here are the drivers that move the price and what to prepare for an accurate number sooner.

Is there a standard percentage for builder's risk cost?

Builder's risk insurance has no honest, universal percentage-of-project-cost formula. An underwriter prices each project from its specific facts: completed value, construction type, schedule, location, catastrophe exposure, contractor experience, loss history, deductibles and jobsite controls. Two projects with the same budget can be priced very differently.

Quick online percentages mislead because they flatten those variables into one number, rarely state their assumptions and ignore Minimum Earned Premium and fully earned terms. A figure that suits a small project in a low-hazard area can be far off for a mid-rise in North Texas hail country. For how the coverage itself works, see our guide to builder's risk insurance in Texas.

The project drivers underwriters price first

Builder's risk underwriters price the project itself first: its completed value, construction type, schedule, location and whether it is new or existing. These facts set the baseline exposure.

Completed project value

Completed project value is usually the starting point for builder's risk pricing, because it sets the amount of property at risk by the end of construction. Understating it to lower premium can leave the project underinsured.

Construction type

Construction type affects builder's risk cost because it changes how a structure behaves in a fire. Frame construction generally carries the highest fire exposure, followed by joisted masonry. Non-combustible and fire resistive construction generally present less, which underwriters often reflect in pricing, along with the number of stories.

Project duration

Project duration matters because a longer build means longer exposure to fire, weather, water and theft. An optimistic timeline that later needs an extension can cost more than pricing the true duration upfront.

Location and catastrophe exposure

Location drives builder's risk pricing because some areas face more severe weather. North Texas sees frequent severe convective storms, including hail and high wind, which can raise rates and lead markets to apply separate wind and hail deductibles. Public protection class and surrounding exposures also matter. See our Dallas-Fort Worth builder's risk page.

Renovation vs new build

Renovation projects are often underwritten differently from new construction, because an existing structure brings its own value, condition and older systems into the risk. Existing property may need separate treatment from the new work.

The contractor and risk-quality drivers

Builder's risk pricing also reflects who is building and how the site is run, because these factors tell an underwriter how likely a loss is.

Percentage complete at binding

Percentage complete at binding affects availability and price, because work in place has been exposed without coverage. Some markets limit how far along a project can be when coverage is first bound. One preferred market generally looks for projects no more than about 10% complete; other markets may consider projects further along, subject to underwriting.

Contractor experience

Contractor experience influences builder's risk cost because underwriters want a general contractor with years in business and similar-project experience. Subcontractor selection and formal subcontract agreements also count. See builder's risk for general contractors.

Prior losses

Prior losses affect builder's risk pricing because they are one of the clearest signals an underwriter has. Past claims can raise the price or narrow terms.

Water, fire and theft controls

Jobsite controls can lower builder's risk cost because they target the most common causes of loss. Underwriters value water-valve maps, water-flow alarms and weatherization plans (the February 2021 winter storm is one reason they ask), debris removal and hot-work permits for fire, and fencing, lighting and cameras for theft.

The policy structure drivers you can influence

Builder's risk cost also depends on how the policy is structured: deductibles, soft costs, delay in completion and the policy term are the levers a buyer can most directly adjust.

Deductibles

Higher deductibles generally lower builder's risk premium, because you retain more of each loss. Many policies add a separate wind and hail deductible, which may be a percentage of value, and sometimes a separate water-damage deductible.

Soft cost limits

Soft cost coverage adds to builder's risk premium because it insures expenses beyond physical repair, such as added interest or fees caused by a covered delay, depending on the policy form.

Delay in completion

Delay in completion coverage adds cost because it responds to lost income or extra expense when a covered loss pushes back completion, subject to the policy's terms. Lenders often require it on income-producing projects.

Policy term and extensions

The policy term shapes builder's risk cost because premium is tied to the length of coverage. If the schedule slips, an extension usually means additional premium and fresh underwriting review, so a realistic original term is often more predictable.

Minimum Earned Premium and fully earned provisions

Minimum Earned Premium (MEP) and fully earned provisions are cost factors because they decide how much premium the insurer keeps if the project ends early or the policy is cancelled.

MEP is the minimum amount or percentage of premium the insurer is entitled to keep once coverage is bound. Example only, not a quote: with a 25% MEP, cancelling shortly after inception does not mean 75% of the premium comes back. The insurer may keep at least the stated minimum, subject to the policy wording. See how Minimum Earned Premium works.

Any return is usually calculated pro-rata (unused premium returned in proportion to time remaining) or short-rate (a return reduced by a penalty factor). Either may be overridden by MEP or fully earned terms.

MEP is not the same as fully earned. MEP sets a floor; a fully earned provision may let the insurer keep 100% of the applicable premium. Not every policy is fully earned, but finishing early does not automatically mean a refund. Read more about fully earned builder's risk premium.

Hypothetical comparison: two projects, two very different prices

A hypothetical comparison shows why one percentage cannot fit every builder's risk project. Example only, not a quote: these two projects have similar budgets, and no premiums are implied.

An underwriter would likely price Project A higher. Project B has the better profile, though being underway means extra review of work in place.

How to get an accurate number faster

The fastest way to an accurate builder's risk number is a complete submission at the start. 4J Insurance Brokerage gathers these items before going to market:

• Budget: completed value, with hard and soft costs separated.
• Schedule: start date, expected completion and phasing.
• Construction type: materials, stories and square footage.
• Site address: for catastrophe exposure and protection class.
• General contractor details: years in business and similar projects.
• Lender requirements: limits, deductibles, soft costs and delay in completion.
• Controls: written water, fire and theft plans.

Frequently asked questions

Is builder's risk insurance a percentage of construction cost?

No. Builder's risk insurance is not priced from a fixed percentage of construction cost. Underwriters price each project from its own facts, including completed value, construction type, duration, location, contractor experience and deductibles, so two projects with the same budget can cost very different amounts.

Who pays for builder's risk insurance?

Builder's risk insurance may be paid for by the owner, the developer or the general contractor, depending on what the construction contract requires. Lenders often set their own requirements as well. The contract and your attorney govern who must buy the policy and who carries the cost.

Do we get a refund if the project finishes early?

Not automatically. If the policy has a Minimum Earned Premium, the insurer may keep at least that minimum. If the policy is fully earned, the insurer may keep 100% of the applicable premium. Any return depends on the policy wording and the cancellation method used.

Does a renovation cost more to insure than a new build?

A renovation can cost more or less than a new build, depending on the project. Underwriters look at the existing structure's value, age, condition and systems, and how existing property is covered. Some renovations carry added exposure, so pricing depends on the specific facts.

How do deductibles affect builder's risk pricing?

Higher deductibles generally lower builder's risk premium because you retain more of each loss. Many policies also include a separate wind and hail deductible, which may be a percentage of value, and sometimes a separate water-damage deductible. Compare the full deductible structure, not just the base amount.

Can a project that is already underway be quoted?

A project already underway can often be submitted for review, case by case. Some markets limit how far along a project can be when coverage is first bound, while other markets may consider projects further along, subject to underwriting. Expect questions about work in place, current condition and prior losses.
