What is builders risk insurance?

Builders risk insurance, also called course of construction (COC) insurance, is property insurance for a building while it’s being built or renovated. It pays to repair or replace the structure and the materials that go into it after a covered loss, such as a fire, theft or water damage.

It’s not liability cover. If someone is injured or their property is damaged, that’s general liability insurance. And it usually ends when the project does, at which point the permanent commercial property insurance takes over.

The building under construction
The structure as far as it’s built, including foundations and framing.
Materials and supplies
Materials on site, in transit or stored elsewhere, before they’re built in.
Temporary structures
Scaffolding, forms, fencing and site sheds used during the work.
Extra costs after a loss
Debris removal and professional fees, and on some policies delay costs, called soft costs.

Who needs builders risk insurance?

A good test: are you building or renovating something that isn’t finished yet, and that would cost real money to repair or replace if it were damaged?

Owners and developers
The person with the most to lose if the building is damaged before it’s finished.
General contractors
Responsible for the work in progress, and often asked by the contract to buy the policy.
Renovations and additions
Major work on an existing building, which a home or property policy may not fully cover.
Tenant build-outs
Fitting out a space you rent, where the improvements are yours to insure.
Owner-builders and small landlords
People managing their own build or renovation, without a contractor carrying the policy.
Projects with a lender
Construction lenders commonly require it as a condition of financing.

What does a real claim look like?

These examples are illustrative, not real cases. In each one, a covered loss damages a project before it’s finished, and the policy is what pays to repair it, after the deductible.

A fire during framing
A fire starts on site during framing and damages the structure and the lumber stacked beside it. Builders risk insurance responds to the damage to the building and to the materials. Injuries to people, or damage to a neighbour’s property, would be a general liability claim.
Stolen materials
Copper pipe and fixtures are stolen from a building site overnight. The policy can respond to stolen materials that are part of the project, depending on its conditions, such as site security. Tools that belong to a contractor usually need their own equipment cover.
Water damage in winter
A pipe bursts in an unheated building over a cold weekend and damages finished work. Water damage from a sudden burst is often covered, while flood and sewer back-up from outside usually have to be added. Ask how the policy treats water before you buy.

Builders risk, course of construction and wrap-up: what’s the difference?

The terms overlap, and one of them isn’t the same product at all.

TermWhat it means
Builders riskProperty insurance for a building and materials during construction or renovation
Course of construction (COC)The same cover, under the name used by many brokers in British Columbia and Alberta
All-risk builders riskA builders risk policy that covers any cause of loss unless it’s specifically excluded
General liabilityCover for injury or damage you cause to others, a different policy
Wrap-up liabilityLiability cover for everyone working on a large project, not property cover
Contractors’ equipment coverCover for a contractor’s own tools and machinery, which builders risk generally excludes

Who buys it, and who insures what on a project?

The construction contract decides who buys the builders risk policy, and it’s worth agreeing before work starts. This table shows the usual pattern.

WhoBuilders risk (the building)LiabilityTools and equipment
The property ownerOften buys itTheir own liability policyNot applicable
The general contractorSometimes buys it, if the contract says soCarries general liabilityInsures their own equipment
Sub-tradesUsually named on the policy, if at allCarry their own liabilityInsure their own tools
The lenderOften asks to be named on the policyNot applicableNot applicable

When does cover start, and when does it end?

Cover is tied to the project, so timing matters. This is a general sequence, and your policy’s conditions decide.

  • Before work starts: cover usually needs to be in place before construction begins, and often before materials arrive.
  • If work pauses or runs late: a policy may have an end date or limits on how long a project can sit idle, so tell your insurer about changes.
  • When the building is occupied or in use: cover may change or stop once someone moves in, even before the work is finished.
  • At substantial completion: builders risk generally ends when the project is finished and handed over, and the permanent property policy has to start at the same moment.

A gap between the two is a common and expensive mistake. Ask your insurer what the policy says about occupancy, delays and the end date, and line up the permanent policy with commercial property insurance.

Project-specific or blanket cover?

Project-specific policyBlanket policy
CoversOne projectSeveral projects over a period, often a year
SuitsA single build or a large renovationA contractor who does many smaller jobs

What isn’t in the base policy, and how to add it

Some common risks are excluded unless you add them. Availability and wording vary by insurer, so ask about each one.

ItemWhat it typically does
Soft costs and delayCovers costs such as loan interest, permit fees or extra rent when a covered loss delays the project
Flood and earthquakeCovers damage from water coming in from outside or from an earthquake
Mechanical or electrical breakdownCovers equipment that breaks down, which base policies generally exclude
Contractors’ tools and equipmentCovered by separate equipment cover, not by builders risk
Property in transit and stored off siteCovers materials that aren’t on the site yet

The difference between hard costs and soft costs matters here. Hard costs are what physically goes into the building: materials, labour and fixtures. Soft costs are the other costs of the project, such as permits, design fees, insurance premiums and interest. Base policies generally cover hard costs, and soft costs are often an add-on.

How much does builders risk insurance cost?

There isn’t one price. What you pay depends on the project. The only reliable number is a quote for your own project, and Clearly Rate doesn’t set prices. The insurer does.

What affects the price

  • The value of the project, including hard costs and, if covered, soft costs
  • Whether it’s a new build, a renovation or an addition
  • Where the site is, and how it’s built
  • How long the project will take
  • Security on site
  • The deductible and any extras
  • Your claims history

How to keep your premium down

Give an accurate project value, since under-stating it can cause problems at claim time. Improve site security, for example with fencing, lighting and locked storage. Ask what a higher deductible would save, and whether you’re comfortable paying that amount yourself.

Is builders risk insurance required?

No general law requires it, but it’s commonly required in practice.

SituationWhat’s usually required
You’re financing the projectConstruction lenders commonly require it, and ask to be named on the policy
You’re bound by a construction contractThe contract usually says who has to buy it
It’s a public or large projectThe owner or authority often sets insurance requirements

Get ready: what an insurer will ask

Having these to hand makes a quote faster.

  • What the project is: a new build, a renovation or an addition
  • The value of the project, including materials and labour
  • Start and expected finish dates
  • The address, and how the building is constructed
  • Who the contractors are
  • What security is on site
  • Who needs to be named on the policy, such as the owner and the lender

What builders risk insurance doesn’t cover

It responds to physical loss or damage to the project. It generally won’t cover:

  • Injury to other people, or damage to their property, which falls under general liability insurance
  • Contractors’ own tools and equipment, which need equipment cover
  • Injuries to workers, which are handled through your provincial workers’ compensation board
  • Faulty design or workmanship, and the cost of fixing your own defective work
  • Wear and tear
  • Damage after the project ends, or once the building is occupied, unless the policy says otherwise

Exclusions vary by insurer, so read the list before you buy.

Business insurance FAQs

Who pays for builders risk insurance?
Usually the property owner, but the construction contract decides, and a general contractor sometimes buys it instead. Agree who buys it, and who has to be named on the policy, before work starts.
Do I need it if I already have contractors' insurance?
Usually, yes, if you’re responsible for the building itself. Contractors’ insurance is mostly liability cover and tools cover, and it doesn’t normally pay to repair the building under construction. See general liability insurance.
Does my home insurance cover a renovation?
Not always. Home policies often limit or exclude cover for major work or for a building that’s unoccupied, so ask your home insurer before you start. Builders risk insurance is an option for larger projects.
What happens if the project runs late?
Cover is usually tied to a policy period or to the project’s progress, so a delay can leave the building uninsured. Tell your insurer about changes to the schedule, and ask what happens if work pauses or runs past the end date.
Is wrap-up insurance the same thing?
No. Wrap-up insurance is a liability policy that covers claims from injury or damage to others on a large project. Builders risk covers the building and materials themselves. Some projects need both.
Do sub-trades need their own policy?
Usually, sub-trades carry their own liability insurance and cover for their tools. The builders risk policy covers the building and materials, so ask whether sub-trades are named on it and what they need to carry.
