Who Pays the Strata Insurance Deductible After a Loss?

Few questions cause more friction in a BC strata than this one: who pays the strata deductible when water comes through a ceiling at 11 PM on a Sunday? The answer is determined by Strata Property Act s. 158, a single subsection that has reshaped BC strata life since premiums and deductibles spiked during the 2020 insurance crisis. We've coordinated many claims across the Sea to Sky, and the pattern is consistent: owners are shocked to learn the strata's deductible, often a substantial five- or six-figure amount, can be billed directly to them when their dishwasher hose fails or a bathtub overflows. This post walks through what the law actually says, what the real-world test is, several illustrative scenarios with the outcome, and how to protect yourself before the next leak.

What SPA s. 158(2)(d) actually says

Subsection 158(2)(d) of the Strata Property Act gives the strata corporation the right to sue an owner (or, more practically, to charge the owner directly) for the strata's insurance deductible if the loss arose out of "an act or omission" of the owner. The wording is deceptively narrow. It doesn't require negligence in the strict common-law sense, it doesn't require intent, and it doesn't require fault in the moral sense. It requires that the loss flow from something the owner did or didn't do.

That subtle wording is why most BC strata deductibles do get charged back to owners. The threshold is low. If the source of water is in your unit and it's not common property, the strata is generally going to invoice you.

The recovery is also fast. The strata doesn't sue you to recover. It invoices you under bylaws and SPA authority, and if unpaid within 30 days it can register a lien against your unit under s. 116. The CRT (Civil Resolution Tribunal) is the venue for any owner challenge.

The real-world responsibility test

We tell every owner in an Avesta-managed building the same three-part test:

1. Is the source in your unit? If yes, go to step 2. If the source is common property, pipes in the wall behind the drywall, the main stack, the building envelope, the boiler room, you are not responsible.
2. Is the source something you own or are responsible to maintain? Appliances, fixtures, hoses, supply lines, plumbing on your side of the shutoff are yours. The strata's bylaws will define this in detail.
3. Did something you do (or fail to do) contribute to the loss? Leaving a tap running, failing to replace a 15-year-old supply hose, ignoring a slow drip for months, running an unattended dishwasher overnight.

If yes to all three, the strata will likely charge back. If the answer to step 1 or 2 is no, the cost stays with the strata corporation.

Scenario 1: The overflowing bathtub

An owner in a Sea-to-Sky strata starts a bath, gets distracted by a phone call, and the tub overflows. Water reaches the units below. The strata files a claim and the deductible is significant.

Outcome: The owner pays the deductible. The cause is squarely within the owner's control: she did the act (started the bath) and the omission (didn't return to turn off the tap). The strata council passes a motion at the next meeting authorizing chargeback. The owner's loss-assessment coverage on her condo policy pays the chargeback if her policy is sized for the building's current deductible. If not, the gap lands on her personally.

This is the most common under-insurance gap we see, see our owner condo insurance guide for what to ask your broker.

Scenario 2: The dishwasher hose failure

A supply hose on a dishwasher in a Sea-to-Sky condo fails overnight. The owner was asleep. Water runs for hours before the unit below notices. Several units are affected and the strata deductible is substantial.

Outcome: Owner pays. SPA s. 158(2)(d) doesn't require the owner to have been awake. The hose is owner property (the supply line on the unit side of the wall) and the failure of an owner-side component triggers recovery. CRT decisions on similar appliance-hose failures have generally confirmed chargebacks in those circumstances: "act or omission" includes the owner's installation and maintenance of the appliance, not just intentional acts.

This scenario is exactly why every owner should carry a deductible buyback endorsement. A new hose costs a few dollars; the deductible without buyback insurance can be five or six figures.

Scenario 3: The drip irrigation system on the patio

An owner in a Sea-to-Sky townhome installs a drip irrigation system for her patio garden. A T-fitting fails, water seeps under the patio door, and damage runs through to the unit below. The strata files a claim.

Outcome: Owner pays the deductible. The owner-installed irrigation system is an owner improvement and any failure is the owner's responsibility. The fact that the installation was within the unit's limited common property (the patio) doesn't change the analysis. The system is owner property. Council documents the chargeback with the adjuster's cause finding and the owner's policy responds.

Scenario 4: The pipe in the wall

A pipe inside a common wall, part of the building's domestic water supply line, fails between units. Several units are damaged. The strata deductible is significant.

Outcome: Strata corporation pays. The cause is common property. There's no s. 158(2)(d) liability because no owner act or omission caused the failure. The strata files the claim, pays the deductible from the contingency reserve (or special levy), and absorbs the cost across all owners. No individual chargeback.

This is why the source diagnosis matters. If the adjuster identifies the pipe as part of the building system, no owner is responsible. If the adjuster identifies the same pipe as owner-side plumbing (past the in-unit shutoff), one owner is responsible. A few feet of pipe can make a five-figure difference. Always get the adjuster's cause line in writing before council votes on chargeback.

How to protect yourself as an owner

Three lines of defence:

• Insurance. Add a deductible buyback (assessment endorsement) to your owner policy. Size loss-assessment coverage to match your building's current strata deductible, review with your broker. The annual cost of the upgrade is usually modest. See our owner unit insurance guide.
• Maintenance. Replace dishwasher and washing machine supply hoses on a regular schedule (braided stainless lasts longer than rubber). Inspect under-sink connections annually. Install simple battery-powered leak sensors under any appliance with a water supply, they're inexpensive and alert you when wet.
• Process. Never run a dishwasher or washing machine while you're out of the unit. Don't leave a tub filling unsupervised. If you're renovating, hire licensed trades and keep receipts. DIY plumbing failures are still your responsibility, but documented professional work helps the adjuster's analysis.

What councils should do

If you sit on a strata council, the most important thing you can do on deductible recovery is document the cause carefully and apply the s. 158(2)(d) test consistently. Don't chargeback common-property losses. Don't refuse to chargeback owner-source losses out of conflict avoidance: that creates an unfunded liability for all owners. And when chargebacks happen, communicate the reasoning clearly to the affected owner with the supporting documentation.
