What is builder's risk insurance?

Builder's risk insurance is a specialized form of property insurance that protects a construction project (and the materials going into it) during the building phase. It is commonly used for new builds, major renovations, additions, and rebuilds.
You may also hear it called a course of construction policy, especially in Canada. The meaning is essentially the same: it is short-term coverage designed for the construction phase when ordinary property policies may not apply the way you expect.

How does builder's risk insurance work?

Builder's risk is usually set up for a specific project. You choose the insured value, select the policy term, confirm what is included (hard costs and soft costs), and add endorsements for exposures like water damage or delayed start-up when needed.

Coverage during construction

A builder's risk policy is intended to protect the project against many common causes of loss during construction.

Common covered triggers often include events like:

  • White checkmark inside a blue circle with a green glow background.
    Fire and smoke damage
  • White checkmark inside a blue circle with a green glow background.
    Theft and vandalism
  • White checkmark inside a blue circle with a green glow background.
    Wind, hail, lightning, explosions

Many policies can also address job site realities such as project interruption and supply delays, and may cover materials while stored off-site or in transit to the job site, depending on wording.

Scope of protection

Builder's risk insurance is typically focused on property and project costs, including the work in progress and many materials that will form part of the completed project.

Depending on policy wording, scope can include:

  • White checkmark inside a blue circle with a green glow background.
    The structure being built or renovated
  • White checkmark inside a blue circle with a green glow background.
    Materials on-site and waiting to be installed, plus materials in transit or stored off-site
  • White checkmark inside a blue circle with a green glow background.
    Temporary structures and installations like scaffolding, site trailers, forms, hoardings, and similar items
  • White checkmark inside a blue circle with a green glow background.
    Debris removal, architectural costs, and certain professional costs tied to an insured loss

Builder's risk is also defined by what it does not cover.

Common exclusions (varies by insurer) can include:

  • White checkmark inside a blue circle with a green glow background.
    Earthquakes and water damage (unless added back by endorsement)
  • White checkmark inside a blue circle with a green glow background.
    Mechanical and equipment breakdown
  • White checkmark inside a blue circle with a green glow background.
    Faulty design, bad planning, or faulty materials
  • White checkmark inside a blue circle with a green glow background.
    Employee theft, contract fees and penalties, and other stated exclusions

The key takeaway: builder's risk is powerful, but it is not “everything that could happen.” Policy wording matters.

Policy duration

Builder's risk insurance is temporary. It is usually written for the expected length of the job, often 3, 6, or 12 months, and can sometimes be extended if the project runs long.

Coverage is intended to respond only while the work is in progress and within the policy period. It does not apply before construction starts or after the work is complete.

Who buys builder's risk insurance?

Builder's risk can be purchased by different parties with a financial interest in the project, such as contractors, homeowners, construction companies, building owners, developers, and subcontractors.

The most important step is not “who should buy it in theory,” but who is responsible in your contract. Clarify it before work starts so there is no gap in protection.

Importance of builder's risk insurance in Ontario

Builder's risk is not only about replacing materials. It is about keeping the project alive after a loss.

Financial protection for contractors

Construction projects carry evolving risk as the build progresses. Builder's risk is designed to act as a safety net through the duration of the project as risks grow and change.

Without coverage, contractors can be exposed to out-of-pocket costs, schedule pressure, and disputes when damage causes delays and rework.

Security for property owners

Owners often have the most at stake financially. Builder's risk helps protect the owner’s investment if the project is damaged or interrupted, supporting the goal of completing the build instead of restarting financially.

Risk mitigation for lenders

Builder's risk insurance is frequently required when securing construction loans because it reassures lenders their investment is protected against setbacks.

In Ontario, builder's risk is not legally required, but it may be required by banks, lenders, project stakeholders, and in some cases municipal bylaws or permit requirements.

Northbridge also notes it is often recommended in Canada by associations like the Canadian Construction Documents Committee (CCDC), which influences standard contracting practices.

Key components of a builder's risk insurance policy

Property coverage

Builder's risk is first and foremost a property-style coverage for the project.

Key items often insured include:
  • White checkmark inside a blue circle with a green glow background.
    Physical damage to the property and replacement of building materials
  • White checkmark inside a blue circle with a green glow background.
    Hard costs such as materials, supplies, and labour
  • White checkmark inside a blue circle with a green glow background.
    Soft costs such as legal fees, architectural fees, and other expenses tied to a covered loss or interruption
A common underwriting detail: your insurance limit should reflect the total value of the project at completion, not just what has been built so far.

Liability coverage

A common mistake is assuming builder's risk replaces liability insurance.

Builder's risk is generally described as property coverage, not liability protection. Liability is typically addressed through commercial general liability or wrap-up liability that is specific to the project.

Some insurers offer project solutions that bundle builder's risk and wrap-up liability together, but it is still important to understand which part covers property and which part covers third-party liability.

Additional endorsements

Construction exposures vary, so endorsements matter. Examples include:
  • White checkmark inside a blue circle with a green glow background.
    Water damage limits and buy-ups:

    some policies cover water damage up to a specified limit, and flood or sewer backup can sometimes be added for additional cost.
  • White checkmark inside a blue circle with a green glow background.
    Delayed opening or start-up:

    optional coverage can address financial losses from delays caused by covered losses, such as increased interest on financing, increased labour costs, or lost revenue.
  • White checkmark inside a blue circle with a green glow background.
    Equipment breakdown:

    often excluded in course of construction policies, but separate equipment breakdown coverage can be important during testing and commissioning.  
We treat endorsements as the difference between “I have insurance” and “I have usable insurance.”

Common misconceptions about builder's risk insurance

It is only for commercial projects

Builder's risk is used for residential new builds, renovations, and commercial and industrial projects. It applies wherever a property is under construction or major renovation.

Builder's risk is the same as homeowner's insurance

Home insurance and commercial property insurance are generally built for properties in regular use. Builder's risk covers the project during construction when standard policies may exclude or limit coverage.

Coverage is not necessary if contractors are insured

Contractor insurance often focuses on liability for the business. Builder's risk focuses on the project property and materials. You may need both, and you should confirm who is responsible for purchasing the builder's risk policy before the job starts.

What it costs: builder's risk insurance cost in Ontario

Builder's risk insurance pricing depends on the project. Key cost drivers often include:
  • White checkmark inside a blue circle with a green glow background.
    Total project value (hard and soft costs)
  • White checkmark inside a blue circle with a green glow background.
    Timeline and policy term
  • White checkmark inside a blue circle with a green glow background.
    Location and job site protections
  • White checkmark inside a blue circle with a green glow background.
    Type of construction and the nature of the work
Some Ontario sources estimate premiums can be roughly 1% to 4% of total project cost (excluding land value), but actual pricing varies widely by risk and insurer appetite.

The Commercial Insurance Difference: In Our Clients' Words

Proactive Broker Relationship.

The most noticeable difference between the team at CommercialInsurance.ca and everyone else was the fact that I no longer felt that I was needed to manage the broker... the brokers came to me with proactive recommendations and knew when to push and shop the market and when not to. When the topic of business insurance comes up, I always refer fellow buinsess owners to commercialinsurance.ca.

Security Blanket For My Business

"I was always the type of custom that never beleived in insurance and only really got it because I had to. Then I met the people at CommcercialInsurance.ca and they asked me questions no one else every did and that's how I knew something was different. They took the time to understand and evaluate the risks. Well, I ended up getting some extra coverage (legal expense) and thank goodness I did. Something fairly innocent turned into something quite nasty and I didn't have to do too much... my coverage took care of it. Nows I look at Insurance as a security blanket for my business."

They had my back

No one likes buying insurance because it's a bit of a bet against yourself. You just hope that when the bad things happen that insurance will do what it said it would do in the first place. That's what'ts great about the experience is over here. They stand behind the policy's that they bind. They never professed to get me the best price, but they did say they have my back, and have my back, they did.
