How Much Does Builders Risk Insurance Cost? 2026 Pricing Guide & Calculator
Quick Answer:
Builders risk (course-of-construction) insurance typically costs 0.1% to 4% of total project value, with most residential builds landing between $400 and $3,000 for a 6 to 12 month term. New construction usually prices around $1.00-$2.00 per $1,000 of completed value; renovations on older structures often run $3.50-$5.50 per $1,000.

Anyone financing new construction or a major renovation eventually hits the same wall: the lender requires proof of builders risk insurance before closing, and the quotes that come back can vary by 2x or more between carriers. Understanding what actually drives the premium — project value, construction type, term length, and deductible choice — turns a confusing quote into a number you can budget for with confidence.
How Much Does Builders Risk Insurance Actually Cost?
Across most residential projects, builders risk premiums fall between $50 and $300 per month, depending on project value, location, and whether the work is new construction or a renovation. A $300,000 new build on a 9-month policy averages roughly $130/month; a $150,000 kitchen remodel on a 6-month term averages closer to $80/month. Larger commercial projects can run $500-$2,000 per month. As a rule of thumb, budget 1% to 4% of your total construction cost for the full policy term, then refine that estimate with our Builders Risk Insurance Calculator.
Sample Premiums by Project Profile
Real-world premium ranges vary widely by project type and location. The table below reflects typical market ranges reported by insurance brokers for common project profiles:
| Project | Value | Term | Typical Premium |
|---|---|---|---|
| New home, frame construction | $300,000 | 9 months | $600 - $2,400 |
| Kitchen remodel | $150,000 | 6 months | $425 - $900 |
| Custom coastal home | $1,200,000 | 12 months | $8,000 - $18,000 |
| Detached ADU | $80,000 | 6 months | $425 - $700 |
| Commercial mixed-use | $2,500,000 | 18 months | $7,000 - $25,000 |
The wide ranges exist because carrier appetite varies enormously for the same risk profile — shopping at least three carriers, rather than accepting the first quote, is the single highest-leverage move you can make before binding a policy.
7 Factors That Move Your Premium
- New construction vs. renovation: Renovations expose an existing structure, its finishes, and older systems to construction risk, which typically adds 60% or more to the rate versus a comparable new build.
- Project value: Bigger projects pay a lower rate per $1,000 of value, but a higher dollar amount overall — a $200,000 project might price near the carrier minimum, while a $14 million project might price closer to $1.00 per $1,000.
- Age of the existing structure (renovations only): Pre-1980 structures often price at $3.50-$5.50 per $1,000 of value; post-1980 structures often drop to $2.00-$2.50.
- Construction class: Frame (wood) construction typically costs roughly 30% more to insure than masonry, because combustible walls increase potential loss severity.
- Location and weather risk: Coastal, wildfire-prone, and hail-corridor states carry higher base rates and often require separate wind/named-storm deductibles.
- Term length: A 6-month policy typically costs about 60%-65% of a 12-month premium, not half, because the carrier still absorbs a fixed underwriting and issuance cost per policy.
- Deductible choice: Raising the all-other-perils deductible from $1,000 to $5,000 commonly saves 8%-12% on premium; going to $10,000 saves another 5%-7%.
New Construction vs. Renovation: Why Renovations Cost More
Renovation projects introduce three risks that new construction skips entirely: the existing structure's electrical, plumbing, and roofing can fail mid-project; materials and finishes already installed can be damaged during work; and older code-era systems (aluminum wiring, polybutylene plumbing, aging roofs) are known carrier red flags. Because of this, fewer carriers are willing to quote renovation risk at all, which by itself pushes pricing higher through reduced competition — not just higher per-carrier rates.
The ~$425 Minimum Premium Floor
Most competitive admitted carriers apply a minimum premium — commonly around $425 — regardless of how small the project is. Below roughly $300,000 of project value, the premium curve flattens: a $150,000 remodel and a $260,000 new build can both land at the same minimum. If your project is small, plan for the floor rather than a proportional 1-4% calculation, which will understate the true minimum cost.
5 Ways to Lower Your Builders Risk Premium
- Raise your deductible: Moving from a $1,000 to a $5,000 deductible commonly saves 8%-12% on premium, as long as you can absorb that amount out of pocket at claim time.
- Match the term to your actual build schedule: Quoting a 12-month policy for a 6-month build pays for coverage you likely won't use — add a small buffer instead of a full extra term.
- Bundle with general liability: Carriers often credit the builders risk premium when the same broker also places your general liability coverage.
- Secure the job site: Fencing, temporary alarms, cameras, and lockable material storage can qualify for job-site protection credits on some policies.
- Choose masonry where structurally feasible: On commercial or hybrid builds where wall systems are still flexible, masonry can pull 10%-25% off the construction-class loading versus frame.
Step-by-Step Example: Pricing a $300,000 Build
Say you're building a new single-family frame home valued at $300,000 with an expected 9-month construction timeline in a moderate-risk location:
- Apply the base rate: New construction at roughly $2.00-$4.00 per $1,000 of value gives a base range of $600-$1,200.
- Adjust for term: A 9-month term runs above the 6-month 60-65% ratio but below a full 12-month premium, landing near the middle of the computed range.
- Adjust for deductible: Selecting a $5,000 deductible instead of $1,000 trims roughly 8%-12% off that figure.
- Add fees where applicable: Non-admitted (E&S) placements in some states add 5%-10% for surplus lines tax, policy fees, and stamping fees on top of the base premium.
Running this same scenario — construction budget, risk profile, and term — through our Builders Risk Insurance Calculator gives you an instant estimate you can bring into a broker conversation.
Common Mistakes That Void Coverage
The most frequent and costly mistake is failing to extend a policy when a project runs long — builders risk policies do not auto-renew, and construction continuing past the expiration date without an approved extension can leave a project completely uninsured during a claim. A close second is underinsuring: the policy limit should reflect the full completed value of the structure (materials, labor, and soft costs), not the land value or the in-progress value — lenders typically catch this gap before closing, but it is worth verifying independently before a claim forces the issue.
