Strata Corporation Insurance: Water Risk, Deductible Decisions & Prevention

Market Context

The insurance market for BC strata corporations is currently in a soft cycle — insurers are competing for business and showing greater flexibility around terms and conditions, with many strata corporations being offered options to reduce water deductibles. The last time deductibles were low — pre-2019 — high claim frequency caused insurers to exit the strata market. During this time, premiums jumped 50–300% at renewal and water deductibles climbed to $250,000–$500,000 (CHOA Bulletin 200-219).

Higher deductibles since 2020 have produced 80% fewer losses triggering strata policies — a healthier claims record directly driving today’s market improvement. Reversing that discipline now risks repeating the cycle.

Water Damage: The Dominant Risk

Common Causes of Water Losses

Prevention: Reducing Water Loss Risk

• Install Water Leak Detection - Automatic shut-off devices that stop losses before they escalate
• Regular Building Inspections - Proactive maintenance to identify vulnerabilities before failure
• Replace Aging Plumbing - Prioritize lines 20+ years old — plumbing failures are the leading cause of water loss
• Educate Owners - Proper appliance use — only run dishwashers/washing machines when home to supervise
• Winterization Protocols - Maintain heat in vacant units; protect sprinkler systems in cold areas
• Enforce Relevant Bylaws - Bylaw compliance around maintenance obligations reduces preventable losses
• Emergency Response Plan - Ensure all contacts know shut-off locations and have 24/7 emergency numbers

Deductible Considerations

Legal counsel often recommends lower deductibles to limit individual owner exposure — a valid perspective. However, from a long-term insurance standpoint, the risk of re-entering a hard market by allowing claim frequency to rise again must also be weighed. The right deductible balances owner protection with the strata’s overall risk profile and premium trajectory.

For strata councils wishing to maintain higher deductibles, this approach offers several potential benefits:

• Fewer nuisance claims on record
  Encourages smaller incidents to be managed without triggering strata-wide claims that remain on the loss record.
• More stable long-term premiums
  Fewer claims support more consistent year-over-year pricing. Small water losses have historically been the primary driver of premium increases at renewal.
• More favourable insurer rating
  Insurers typically apply more favourable pricing when higher deductibles are in place, which can help keep overall premiums lower.
• Encourages owner accountability
  Maintaining higher deductibles can encourage unit owners and tenants to be more mindful of their actions and address maintenance issues promptly.

Tip #1: Deductible decisions should balance risk, cost, and long-term sustainability, and are best reviewed in consultation with an insurance broker.

What Unit Owners Should Do — Regardless of the Deductible Level

Whether the strata’s water deductible is $25,000 or $150,000, every unit owner needs their own unit owner policy with sufficient deductible assessment coverage. Under Section 158 of the Strata Property Act, the strata can recover its deductible from the owner whose unit was the source of a loss — even without proving negligence (see Mari v. Strata Plan LMS 2835). Coverage limits in the $25,000–$50,000 range are priced very similarly on a unit owner policy. Increasing to $75,000–$100,000 typically adds only $150–$300 per year — modest protection against a potentially significant liability.
