How Does Builders Risk Insurance Work? A Guide for Colorado Contractors
Updated: Sep 30
Imagine your crew is months into a construction project. The framing is up, materials have been delivered, and everything is moving toward completion. Then a severe Colorado storm rolls through overnight, damaging part of the unfinished structure and thousands of dollars in materials.
Who pays for the damage?
That is where builders risk insurance may come into play.
Construction projects create unique property risks because an unfinished building doesn't fit neatly into the same insurance category as a completed property. Contractors, developers, owners, and other stakeholders can have significant amounts of money invested in a project before anyone receives the keys.
So, how does builders risk insurance work? Builders risk insurance, also called course of construction insurance, is property coverage designed to protect a building or structure while it is being constructed or renovated. Depending on the policy, coverage may extend to materials, supplies, fixtures, and equipment that will become a permanent part of the structure.
For Colorado contractors, understanding this coverage can be an important part of protecting a project from the first stages of construction through completion.
What is Builders Risk Insurance?
Builders risk insurance provides temporary property coverage for a construction or renovation project.
Unlike commercial property insurance intended for a completed building, builders risk coverage addresses the changing property exposure of an active construction site.
Consider a new commercial building. At the beginning, there may be little more than a foundation. Months later, the site may contain framing, windows, roofing materials, plumbing fixtures, electrical components, HVAC systems, and other valuable materials.
Builders risk insurance can help protect that growing investment from covered losses during construction.
Coverage can be appropriate for projects including:
New residential construction
New commercial buildings
Major renovations
Building additions
Remodeling projects
Certain installation projects
The right coverage depends on factors such as project value, location, construction type, duration, and contractual requirements.
How Does Builders Risk Insurance Work?
A builders risk policy generally covers a specific construction project for a defined period.
Before work begins, the owner, contractor, developer, or another responsible party purchases coverage based on the characteristics and expected completed value of the project.
If covered property is damaged by a covered event during the policy period, a claim can be filed. The insurer evaluates the loss based on the policy's terms, limits, deductibles, conditions, and exclusions.
For example, suppose a contractor is constructing a new commercial building in Colorado and a covered windstorm damages partially installed roofing and materials stored at the jobsite. If the damaged property and cause of loss fall within the policy's coverage, builders risk insurance may help pay for repairs or replacement.
However, policies can differ considerably. Contractors should never assume that every builders risk policy provides the same protection.
What Does Builders Risk Insurance Cover?
Builders risk coverage generally centers on the construction project and property intended to become part of the finished structure.
Structure Under Construction
The partially completed structure itself is generally the primary focus of the policy.
As more labor and materials become incorporated into the building, its value increases. A major loss near the end of construction can therefore be especially expensive.
Building Materials and Supplies
Depending on the policy, builders risk insurance may cover materials and supplies intended to become part of the finished structure, such as:
Lumber and drywall
Roofing materials
Windows and doors
Electrical components
Plumbing fixtures
Flooring and cabinets
HVAC components
Contractors should pay particular attention to materials that are being transported or stored away from the jobsite. Coverage for property in transit or temporary off-site storage can vary and may be subject to separate limits.
Fixtures and Installed Equipment
Equipment and fixtures that will become a permanent part of the completed building may also be covered, depending on policy terms.
This distinction matters because reusable contractor tools and equipment are generally a different exposure. Tools, machinery, and mobile equipment may require contractors equipment or inland marine coverage rather than relying on builders risk insurance.
Additional Expenses
Some policies may also provide or offer coverage for expenses such as debris removal or certain additional costs resulting from a covered loss.
Other protections, including certain soft costs or delays associated with a covered loss, may require additional coverage or endorsements.
What Types of Losses May Be Covered?
The exact causes of loss covered vary by policy. Depending on the form, builders risk insurance may provide protection against events such as:
Fire
Lightning
Wind
Hail
Theft
Vandalism
Certain explosions
For Colorado contractors, weather deserves particular attention. Hail, high winds, snow, freezing temperatures, and rapidly changing conditions can create challenges for active construction projects.
However, a hazard being common in Colorado does not mean every builders risk policy automatically covers it. Contractors should verify how their specific policy handles relevant weather exposures, deductibles, and exclusions.
What Doesn't Builders Risk Insurance Cover?
Builders risk insurance is not designed to cover every problem that can occur during construction.
Depending on the policy, exclusions or limitations may apply to issues involving:
Normal wear and tear
Employee theft
Faulty workmanship
Defective materials
Faulty design or planning
Mechanical breakdown
Certain water damage
Flood or earth movement
Contractual penalties
War or government action
Some excluded or limited exposures may be addressed through endorsements or separate policies.
Because exclusions vary, contractors should focus on the actual policy language rather than assuming a particular loss will or won't be covered.
Builders Risk vs. General Liability Insurance
One common source of confusion is the difference between builders risk and general liability insurance.
They serve different purposes.
Builders risk is property coverage. It is designed to protect covered property associated with the construction project against covered physical losses.
Commercial general liability insurance generally addresses claims involving bodily injury or property damage to others arising from business operations, subject to policy terms and exclusions.
For example, if a covered fire damages an unfinished structure, builders risk coverage may apply to the project damage. If a visitor is injured at the jobsite and alleges the contractor was negligent, general liability coverage may be relevant instead.
Colorado contractors may need both because one is not a substitute for the other.
Who is Responsible for Builders Risk Insurance?
Depending on the project, builders risk insurance may be purchased by the:
Property owner
General contractor
Developer
Another party with an insurable interest
Construction contracts frequently specify who is responsible for obtaining coverage.
Contractors should review those requirements before beginning work rather than assuming the owner or another party has taken care of everything.
Multiple parties can have a financial interest in a project, including owners, general contractors, subcontractors, developers, and lenders. The policy should be structured appropriately for the contractual arrangement and the parties involved.
Even when someone else purchases the policy, contractors should verify that appropriate coverage is actually in place.
How Much Builders Risk Insurance Do You Need?
Builders risk limits are commonly based on the project's expected completed value rather than simply what has been spent at the time the policy begins.
The appropriate valuation method depends on the policy, but contractors should be prepared to provide accurate project information, including:
Total project value
Construction type
Square footage
Location
Project scope
Start and completion dates
Materials being used
Storage arrangements
Existing structures involved in renovations
Site security and protection measures
Accurate values matter. A project that is only 20% complete today could eventually represent a much larger property exposure.
When Does Builders Risk Insurance End?
Builders risk is temporary coverage, so understanding when the policy ends is critical.
Depending on the policy, coverage may terminate when:
The policy expires
Construction is completed
The property becomes occupied
The insured's interest in the property ends
Permanent property coverage takes effect
Another termination condition in the policy occurs
Contractors should pay particular attention to this transition near the end of construction. If builders risk coverage ends before permanent property coverage begins, a potential insurance gap can result.
Project delays are another consideration. If construction takes longer than expected, the policy may need to be extended if the insurer permits it.
What About Renovation Projects?
Builders risk isn't limited to ground-up construction. It can also be important for major remodeling and renovation projects.
These jobs can create an additional complication: the existing building.
Suppose a contractor is renovating an existing commercial building and a fire damages both the newly installed materials and part of the original structure. Whether both portions are covered depends on how the insurance program is structured.
Contractors should specifically ask how existing property is treated when arranging builders risk coverage for renovations. Never assume the existing structure is automatically covered.
Why Builders Risk Matters for Colorado Contractors
Colorado construction projects face a wide range of exposures.
Wind and hail can damage unfinished structures and materials. Snow and freezing temperatures can complicate projects. Depending on location, contractors may also need to consider wildfire, flood, or other site-specific exposures.
Then there are risks common to construction sites everywhere, including theft, vandalism, and fire.
A significant property loss can do more than destroy materials. It can interrupt the construction schedule, delay other trades, push back completion, and create additional expenses.
Builders risk insurance cannot prevent those events, but appropriate coverage can help protect the financial investment in a project when a covered loss occurs.
Common Builders Risk Mistakes to Avoid
Understanding how builders risk insurance works is only part of the equation. Contractors should also avoid several common mistakes.
Assuming Someone Else Has It Covered
If the owner or developer is purchasing the policy, verify the coverage instead of simply assuming the project is protected.
Choosing Coverage Based Only on Price
Premium matters, but so do deductibles, exclusions, limits, and coverage for materials in storage or transit. A less expensive policy could provide less protection.
Forgetting About Materials Away From the Site
If valuable materials will be stored at another location or transported to the project, determine how the policy treats them.
Ignoring the Completion Date
Know what triggers the end of coverage and what happens if the project is delayed.
Treating Builders Risk as Complete Contractor Coverage
Builders risk is only one part of a contractor's insurance program. Depending on the business, additional coverage could include general liability, commercial auto, workers' compensation, contractors' equipment, umbrella liability, and other specialized policies.
Questions to Ask Before Starting a Project
Before purchasing or relying on a builders risk policy, ask:
Who is responsible for purchasing coverage?
Who is protected under the policy?
What is the project's completed value?
Which causes of loss are covered?
What are the major exclusions?
How are wind and hail handled?
Is theft covered?
Are materials in transit or off-site storage covered?
How is an existing structure handled during renovations?
What deductibles and special limits apply?
When does coverage begin and end?
What happens if the project takes longer than planned?
Addressing these questions before construction begins can help uncover potential gaps before they turn into costly surprises.
Protect Your Colorado Construction Project
So, how does builders risk insurance work? At its core, it provides temporary property protection for a construction project during a time when the building, materials, and financial investment may be particularly vulnerable.
But the details of the policy matter.
Every construction project has its own combination of values, timelines, contractual requirements, materials, and risks. Colorado contractors should make sure their builders risk coverage reflects the actual project rather than relying on assumptions or a one-size-fits-all approach.
Weedin Agency can help Colorado contractors evaluate builders risk insurance and other business coverage based on the projects and risks they face. Before breaking ground on your next project, consider reviewing your insurance needs with an experienced professional.
