Builders Risk Insurance
Call Us: 603-766-3733
Construction in New Hampshire means dealing with realities most other states don't share: a freeze-thaw cycle that can destroy exposed framing overnight, coastal flood zones that shift with updated FEMA maps, and a short building season that makes every delay expensive. If you're breaking ground on a commercial project, a custom home, or a major renovation, your standard general liability or property policy won't cover the structure while it's being built. That gap is exactly where builders risk insurance steps in, and understanding how it works in New Hampshire specifically can save you from a six-figure headache.
New Hampshire's insurance market is tightening, too. Homeowners premium written statewide
jumped from $584M in 2023 to $661M in 2024, a 13.2% year-over-year increase. That pressure trickles into construction-related policies. Builders risk coverage, limits, and state requirements deserve careful attention before you sign a single contract. Here's what New Hampshire business owners and property developers actually need to know.
The Essentials of Builders Risk Insurance for New Hampshire Projects
Builders risk insurance is a temporary property policy that protects a structure during construction, renovation, or major remodeling. It covers the building itself, materials on-site, and often materials in transit. The policy period typically aligns with your construction timeline, usually six to twelve months, with extensions available if the project runs long.
What makes this coverage distinct from a standard property policy is its focus on a structure that doesn't yet exist in its final form. You're insuring something that changes value every week as work progresses. That's a fundamentally different risk profile than insuring a finished building.
Core Coverage for Structures and Materials
A standard builders risk policy covers the physical structure under construction against perils like fire, wind, lightning, hail, vandalism, and theft. It also typically covers building materials and supplies stored on the job site or at a temporary storage location. Some policies extend to scaffolding, temporary structures, and equipment that becomes a permanent part of the building.
The cost is tied directly to the project's total value. Builders risk insurance rates typically fall between 1% and 5% of total construction value, with most policies costing between $1,000 and $7,000 annually depending on project specifics. For a $2 million custom home build in the Lakes Region, you might budget $20,000 to $100,000 at the extremes, though most projects land somewhere in the middle range. Monthly costs generally run $40 to $85 per $100,000 of value.
Who Needs Coverage: Owners vs. Contractors
This is where confusion creeps in. Either the property owner or the general contractor can purchase the policy, and the contract language usually dictates who's responsible. On larger commercial projects, lenders almost always require the owner to carry it. On residential builds, it varies.
Here's the practical issue: if the contractor carries the policy, the owner may not be listed as an insured party, which creates gaps if a dispute arises after a loss. The smartest approach is making sure the policy names all parties with an insurable interest, including the owner, GC, and subcontractors. An agency like Avery Insurance Agency, which has spent over 125 years working with New Hampshire property owners, can review your construction contract and identify exactly who needs to be covered before the first nail gets driven.

New Hampshire Specific Risks and Coverage Considerations
New Hampshire's geography creates a unique set of construction hazards. The state stretches from the seacoast to the White Mountains, and the risks at each end are dramatically different. A policy that works for a Portsmouth waterfront project won't necessarily protect a Franconia ski lodge build.
Managing Winter Weather and Ice Dam Hazards
Anyone who's built in New Hampshire knows the window between mud season and first frost is painfully short. Exposed structures face months of snow load, ice accumulation, and freeze-thaw cycling that can crack foundations and warp framing. Ice dams on partially completed roofs are a real and recurring problem.
Most builders risk policies cover wind and hail damage, but ice dam damage and weight of snow or ice may require specific endorsements. If your project will have an exposed roof deck through the winter, confirm that your policy explicitly covers collapse or damage from snow and ice loading. This is not a theoretical risk in New Hampshire: it's a near certainty if construction stalls during winter months.
Flood Zones and Coastal Property Requirements
New Hampshire has only 18 miles of coastline, but those miles are densely developed and increasingly flood-prone. Properties in Hampton, Rye, and Seabrook often fall within FEMA-designated flood zones, and standard builders risk policies exclude flood damage entirely.
If your project sits in a flood zone, you'll need a separate flood policy or a specific flood endorsement on your builders risk coverage. FEMA's National Flood Insurance Program covers some scenarios, but private flood insurance often provides better limits for high-value construction. Inland flooding along the Merrimack and Connecticut Rivers is also a concern. Don't assume flood risk is limited to the coast.
Determining Policy Limits and Valuation Methods
Setting the right coverage limit on a builders risk policy is more complicated than it sounds. Get it wrong, and you'll either overpay for coverage you don't need or find yourself drastically underinsured after a major loss.
Replacement Cost vs. Actual Cash Value
| Feature | Replacement Cost | Actual Cash Value |
|---|---|---|
| Payout basis | Cost to rebuild with similar materials | Depreciated value at time of loss |
| Premium cost | Higher | Lower |
| Best for | New construction, high-value builds | Budget-sensitive renovations |
| Risk | Potential over-insurance early in project | Significant gap between payout and rebuild cost |
For most New Hampshire construction projects, replacement cost coverage is the right call. Actual cash value might save you on premium, but if a fire destroys a half-finished $3 million home, the depreciated value of partially installed materials won't come close to covering your rebuild costs.
Accounting for Soft Costs and Delay in Completion
Hard costs like lumber, concrete, and labor are the obvious items to insure. But what about architect fees, permit costs, loan interest, and temporary housing for the owner during a rebuild? These soft costs add up fast, and a standard builders risk policy doesn't always cover them.
A delay in completion endorsement is particularly valuable in New Hampshire's compressed building season. If a covered loss pushes your project from October into the following spring, you're looking at five or six months of additional carrying costs. Loan interest alone on a $2 million project could run $50,000 or more during that delay. Make sure your policy accounts for these real-world financial consequences.
New Hampshire doesn't mandate builders risk insurance by statute, but that doesn't mean you can skip it. The requirements come from other directions: lenders, municipalities, and contract language.
NH Department of Insurance Guidelines
The New Hampshire Department of Insurance regulates all insurance products sold in the state, including builders risk policies. Insurers must file their rates and forms with the department, and rate changes have been averaging around 7.4% in 2024, which is a moderation from steeper increases in prior years.
The state doesn't set minimum coverage requirements for builders risk specifically, but it does enforce consumer protection standards. If a claim is denied unfairly, the Department of Insurance handles complaints and can intervene. Knowing this recourse exists matters, because builders risk claims can be contentious, especially when the cause of loss is disputed.
Meeting Lender and Municipality Insurance Mandates
If you're financing construction, your lender will almost certainly require builders risk coverage with them named as loss payee. Most banks want coverage equal to the full completed value of the project or the loan amount, whichever is greater. They'll also want to see the policy before releasing construction draws.
Many New Hampshire municipalities require proof of insurance before issuing building permits, particularly for commercial projects. Towns like Hanover, Exeter, and Nashua have been increasingly strict about this. Check with your local building department early in the permitting process so insurance requirements don't cause delays.
Optimizing Your Policy for Maximum Protection
A builders risk policy is only as good as its terms. The default coverage on most policies leaves gaps that can be expensive to discover after a loss.
Common Exclusions and How to Bridge the Gaps
Standard exclusions on builders risk policies typically include:
- Flood and earthquake damage
- Employee theft (requires a separate crime or fidelity bond)
- Faulty workmanship or design defects
- Damage to existing structures during renovation
- Mechanical breakdown of installed equipment
Each of these can be addressed with endorsements or companion policies. For renovation projects, an "existing structures" endorsement is critical because the standard policy only covers the new work, not the original building. Avery Insurance Agency's consultative approach is particularly useful here: their team reviews your project scope and contract to identify vulnerabilities you might not have considered, so you're not discovering coverage gaps during a claim.
When to Transition to Permanent Property Insurance
Your builders risk policy expires when construction is complete, and there's often a grace period of 30 to 90 days after the certificate of occupancy is issued. Missing this transition window can leave your brand-new building completely uninsured.
The best practice is to start shopping for permanent property coverage about 60 days before your expected completion date. This gives you time to get accurate replacement cost estimates on the finished structure and ensures there's no lapse in coverage. For high-value properties, especially those over $1.5 million, the permanent policy may need specialized underwriting that takes time to arrange.
Getting builders risk coverage right in New Hampshire comes down to understanding your project's specific exposures, setting limits that reflect real rebuild costs (including soft costs and delays), and making sure your policy addresses the state's unique weather and flood risks. Don't rely on a generic policy pulled off a shelf.
Talk to your contractor about who's responsible for coverage before signing the construction contract. Review your lender's requirements early. And if your project involves coastal property, winter exposure, or a value above $1.5 million, work with an agency that understands New Hampshire's construction insurance market inside and out.
FAQ
How long does a builders risk policy last? Most policies run 6 to 12 months, matching your construction timeline. Extensions are available but usually require additional premium and underwriter approval.
Does builders risk insurance cover theft of materials from the job site? Yes, most policies cover theft of building materials. However, employee theft is typically excluded and requires a separate fidelity bond or crime policy.
Can I get builders risk coverage for a renovation project? Absolutely, but you'll likely need an "existing structures" endorsement to protect the original building. Without it, only the new construction work is covered.
Is builders risk insurance required by New Hampshire law? No state statute mandates it, but your lender, municipality, or construction contract will almost certainly require it.
Who pays for builders risk insurance: the owner or the contractor? It depends on your contract. Either party can purchase it, but the policy should name all parties with an insurable interest to avoid coverage disputes.

Got Questions? We’ve Got Answers.
Straight Answers From the Advisors Who Know This State Best
What does it mean that Avery is an independent insurance agency?
An independent agency like Avery is not tied to any single insurance company. We represent multiple top-rated carriers, which means we can shop the market on your behalf and recommend the coverage that truly fits your needs — not the one that benefits any single insurer.
This independence gives you access to more options and unbiased advice. Our advisors are compensated to serve your interests, not to push a specific product. That is a significant advantage over captive agents who can only offer one carrier’s policies.
How much does it cost to work with an Avery advisor?
There is no direct cost to you for working with an Avery advisor. Independent agents are compensated through commissions paid by the insurance carriers when a policy is placed. You receive expert guidance, market comparisons, and ongoing service at no extra charge.
In fact, many clients find that working with Avery saves them money. Our advisors know how to identify the right coverage levels so you are not paying for protection you do not need, and you are not left exposed where you do.
Does Avery help with claims?
Yes — and this is one of the most important things that sets Avery apart. When you have a claim, our in-house claims advisors go to work for you. We guide you through the process, communicate with the insurance company, and advocate for a fair and timely outcome.
Several of our team members hold professional claims designations, including AIC and AINS. We do not just help you file paperwork — we actively represent your interests to make sure you receive the full benefit your policy provides.
Where in New Hampshire does Avery provide coverage?
Avery serves clients throughout the state of New Hampshire from our offices in Wolfeboro and Portsmouth. Whether you live in the Lakes Region, the Seacoast, the White Mountains, or the Merrimack Valley, an Avery advisor is ready to help you find the right coverage.
Our advisors understand the specific risks that come with living and doing business in New Hampshire — from harsh winter weather to seasonal watercraft exposure. We apply that local knowledge to every coverage recommendation we make.
How does Avery handle high-value homes and assets?
Avery offers a dedicated Premier Client Services program for clients with homes valued over .5 million, significant investment portfolios, fine art collections, jewelry, yachts, and other complex assets. This program pairs you with a specialist who understands the unique risks of high-net-worth households.
Through carriers that specialize in high-value personal lines, we provide guaranteed replacement cost coverage, agreed value policies, and comprehensive risk management strategies. Your advisor will conduct a detailed review of your full asset portfolio to make sure nothing is overlooked or underinsured.
How often should I review my insurance coverage?
Avery recommends a full coverage review at least once a year. Major life events — buying a home, starting a business, adding a vehicle, getting married, or making significant home improvements — are all good triggers for an immediate review outside your annual cycle.
Insurance needs change over time, and policies that were right for you a few years ago may leave gaps today. Avery advisors proactively reach out to clients for annual reviews and keep up with changes in the insurance market that could affect your coverage or premium. Our goal is to make sure you are always protected and never paying for coverage that no longer fits.
