Do I need insurance for basement renovation in a Vancouver strata building?

Yes, you absolutely need insurance coverage before starting a basement renovation in a Metro Vancouver strata building — and in most cases, you need it from multiple angles. Your strata corporation's master insurance policy, your own homeowner (strata unit) insurance, and your contractor's liability and WorkSafeBC coverage all play distinct roles in protecting you during and after the project.

Start with your strata corporation's insurance. The master policy typically covers the building's common property and original building components — including the original structure, common walls, and building envelope. However, it generally does not cover improvements or betterments you make to your unit, which includes a basement finishing project. Under BC's Strata Property Act, if your renovation causes damage to common property or another owner's unit (for example, a plumbing mishap that floods a neighbouring unit), you could be held personally liable for the strata's insurance deductible. In Metro Vancouver, strata insurance deductibles have risen dramatically since 2020, and deductibles of $25,000 to $100,000 or more are now common. This means if your basement renovation triggers a claim, you could be on the hook for a very large sum.

This is why your personal strata unit insurance (often called an HO-6 policy or condo insurance) is critical. Make sure your policy includes adequate betterments and improvements coverage to cover the value of your basement renovation — if you are spending $40,000-$60,000 on finishing, your improvements coverage should reflect that amount. Also confirm you have personal liability coverage of at least $2 million, and ask your broker specifically about coverage for your strata's deductible through a deductible assessment endorsement. This endorsement, which typically costs $50-$150 per year, can save you from a devastating out-of-pocket expense if something goes wrong. Contact your insurance broker before the project begins and inform them of the planned renovation — failure to disclose a major renovation could void your coverage.

Contractor Insurance Requirements

Every contractor working on your basement in British Columbia must carry WorkSafeBC coverage — this is not optional. WorkSafeBC coverage protects you from liability if a worker is injured on your property. Ask your contractor for their WorkSafeBC account number and verify it online at worksafebc.com before work begins. If an unregistered contractor or their worker is injured in your home, WorkSafeBC can assess the costs against you as the homeowner.

Beyond WorkSafeBC, your contractor should carry commercial general liability (CGL) insurance with a minimum of $2 million coverage. This protects you if the contractor's work causes property damage — such as a burst pipe, fire, or structural damage to your unit or a neighbouring unit. Request a copy of their certificate of insurance and confirm it is current. In the Metro Vancouver market, reputable basement contractors carry $2-$5 million in liability coverage as standard.

Many strata corporations in Metro Vancouver now require contractors to name the strata corporation as an additional insured on their liability policy before work can begin. Your strata management company will provide the specific requirements, and your contractor's insurance broker can issue a certificate of insurance naming the strata as additional insured — this is a routine request that costs the contractor nothing.

Finally, check whether your strata bylaws require you to post a damage deposit before starting renovation work. Many Metro Vancouver strata corporations require deposits of $500-$2,000 to cover potential damage to common areas (hallways, elevators, parking areas) during the renovation. This deposit is refundable after the project is complete and inspected by the strata.

The total cost of proper insurance for a strata basement renovation is modest — typically $100-$300 in additional annual premiums for your unit policy upgrades — but the protection is enormous. Do not skip this step. If you need help finding an insured, WorkSafeBC-registered basement contractor in Metro Vancouver, Vancouver Basement Finishing can match you for free.
