Your home insurance probably stops when the renovation starts
Homeowners assume their existing policy carries through the project. Most policies were written for a house somebody lives in, and a construction site is a different risk. Ask before the work starts, not after something happens.

In short, Standard homeowner insurance policies are underwritten for an occupied dwelling and commonly contain conditions relating to vacancy and material change in risk, which a construction project can trigger. Course of construction coverage, sometimes called builders risk, is the product designed for a property under construction. Separate questions arise about who carries liability coverage, whether subtrades are covered, what happens to materials stored on site, and whether the homeowner remains insured while living elsewhere. These should be confirmed in writing with the insurer and the builder before work begins rather than assumed.
Of all the things a homeowner has to sort out before a renovation, insurance gets the least attention and carries some of the largest downside.
The reason is straightforward. Most people assume the policy they already have continues to do what it has always done. It might. But the assumption is worth testing before the work starts rather than after something happens.
Why a construction site is a different risk
A standard homeowner policy is generally underwritten for an occupied dwelling. That is the risk the insurer priced.
A house mid-renovation is a different proposition. The building may be open to weather. Materials arrive and sit on site. Trades come and go with tools and equipment. Systems are disconnected and reconnected. Sometimes nobody is living there at all.
Policies commonly contain conditions dealing with vacancy and with material changes in risk, which is the insurer's way of saying the thing they insured should stay roughly the thing they insured. Whether a particular project engages those conditions depends on the policy and the scope, and only the insurer can answer that.
I cannot tell you what your policy says. I can tell you that finding out afterwards is the expensive way to learn.
The coverage built for this
Course of construction coverage, sometimes called builders risk, is the product designed for a property while it is being built or renovated.
It exists precisely because the ordinary homeowner policy was not written for this situation. Who arranges it, who is named on it, and what it covers are contract matters, and they should be settled in the contract rather than assumed by both parties in different directions.
That last point is the failure mode. The homeowner assumes the builder has it. The builder assumes the homeowner's policy responds. Neither checks, because each believes the other has. That conversation costs ten minutes at contract stage.
Liability is a separate question
Property coverage and liability coverage answer different questions, and both matter.
Property coverage responds when the building or materials are damaged. Liability responds when somebody is injured or someone else's property is damaged. On a site with trades working, equipment operating, and in urban Metro Vancouver a neighbour within a few metres, both exposures are live.
Ask specifically who carries liability coverage, at what limits, and whether the homeowner is named where that is appropriate. Ask it as a question with an answer rather than as reassurance.
Subtrades are separate businesses
This is the gap owners most often miss, and it parallels the situation with payment that makes the builders lien holdback necessary.
The framer, the electrician, the plumber and the roofer are typically separate businesses. They are not automatically covered by the general contractor's policy, and whether they hold their own coverage is a matter of what the builder requires of them.
So the question is not simply whether your builder is insured. It is whether subtrades are required to carry coverage, at what limits, and whether proof is collected before they set foot on site. A well-run project collects certificates of insurance as a matter of course, and a builder who does this will not be offended by the question.
Materials on site
Materials delivered but not yet installed occupy an awkward position that is worth asking about explicitly.
They are on your property, but not yet part of your building. Depending on the contract and the policies involved, they may or may not be covered, and by whom is not obvious. On a project with long lead items ordered early, the value sitting on site at any moment can be substantial.
One question resolves it: if the materials delivered last week were destroyed tonight, whose policy responds? If nobody can answer immediately, that is the gap.
Moving out changes things
If the family is relocating for the duration, that is a fact the insurer needs, for two reasons.
First, vacancy conditions. An unoccupied house is a different risk and policies commonly address it directly.
Second, coverage for the people. Where you are living and what happens to your possessions during that period are their own questions, separate from what is happening to the building. We cover the practical side of relocating in should you live in your home during a renovation, and the insurance implication belongs in that decision rather than after it.
Warranty is not insurance for the work
Worth separating two things that get conflated.
Home warranty insurance in BC addresses defects in a new home after completion, under the provincial framework, and we cover it in the 2-5-10 home warranty explained. Construction insurance addresses loss and liability while the work is happening.
Different timing, different risks, different products. A project can require both, and having one says nothing about the other.
The conversation to have
Before work starts, in writing, with answers rather than assurances.
- Call your insurer, describe the actual scope, and ask whether your policy responds and what conditions apply.
- Ask whether you will be vacating, and disclose it if so.
- Ask your builder what coverage they carry and request certificates.
- Ask whether subtrades are required to carry coverage, at what limits, and whether proof is collected before they start.
- Establish who bears the risk on materials delivered to site.
- Confirm the contract says all of this rather than leaving it to be worked out later.
Frequently asked
Does my existing home insurance cover a renovation?
That depends on the policy and the scope of work, and it is a question for your insurer rather than your builder. Standard policies are generally underwritten for an occupied dwelling and commonly contain conditions about vacancy and about material changes in risk. A significant renovation can engage those conditions, which is why the conversation needs to happen before work begins.
What is course of construction insurance?
It is the coverage designed for a property while it is under construction, sometimes called builders risk. It exists because a construction site presents different exposures from a lived-in home: the building may be open to weather, materials sit on site, and trades are coming and going. Who arranges it and who is named on it are contract questions to settle before the work starts.
Who should carry the insurance, me or the builder?
It varies by contract and by project, and the important thing is that the contract says so explicitly rather than leaving it to assumption. What matters more than the default is that every party knows which policy responds to which situation, and that the homeowner has seen the documents rather than been told they exist.
Are subtrades covered by my builder's insurance?
Not automatically, and this is worth asking directly. Subtrades are typically separate businesses carrying their own coverage, and whether they are required to hold it, at what limits, and whether proof is collected before they start work, are all questions your builder should be able to answer specifically.
What is a certificate of insurance?
A document from an insurer confirming that a policy exists, what it covers, the limits, and the period. Asking for certificates from the builder and from the subtrades is normal practice, and a well-run project collects them before the trades start rather than after an incident makes somebody go looking.
What happens if the house is empty during the work?
This is where vacancy conditions in a standard policy commonly come into play. A house that is unoccupied for an extended period presents a different risk to an insurer, and policies often address that explicitly. If you are moving out for the project, that is a specific fact to disclose to your insurer rather than something to sort out later.
Does insurance cover materials stored on site?
It depends on the policy and how it is written, and materials on site are one of the common gaps. Delivered materials that have not yet been installed can sit in a space between coverages, so it is worth asking who bears that risk and whether it is addressed.
How does this relate to the 2-5-10 home warranty?
They address different things. Home warranty insurance in BC covers defects in a new home after it is complete, under the provincial framework. Construction insurance addresses loss and liability while the work is underway. A project can need both, and one does not substitute for the other.
It is an hour of unglamorous work against the largest asset most families own. If you are planning a renovation or a build in Metro Vancouver and want to understand how a well-structured contract handles risk before you sign one, book a free consultation.
