Calgary has been dealing with significant rainfall over the past several days. Environment Canada issued a rainfall warning for the city with accumulations between 50 and 100 mm expected, and river levels have been closely monitored as a result. For people living in condominiums across Calgary and surrounding communities, events like this tend to raise a question that comes up surprisingly often even in dry years: if water gets in and causes damage, who is actually responsible for the cost?
The answer involves two separate insurance policies, and understanding how they interact is something every Alberta condo owner and board member should be familiar with before a claim ever happens.
Under the Condominium Property Act and the Condominium Property Regulation, every condominium corporation in Alberta is legally required to carry property insurance. This is not optional. The corporation’s policy must cover the common property and the units themselves at full replacement value, based on what is described in the corporation’s Standard Insurable Unit Description (SIUD).
The SIUD is a document that defines exactly what a “standard unit” includes for insurance purposes, things like standard flooring, cabinetry, fixtures, and finishings as they existed when the building was originally constructed or as subsequently amended by the corporation. CondoLawAlberta explains this clearly: the corporation’s insurance covers the building itself and the units as described in the SIUD, but it does not extend to personal belongings, unit improvements made by owners, or any liability that originates within a private unit.
That distinction is where a lot of confusion begins.
Most owners assume that because the corporation carries insurance, they are largely covered in the event of water damage. The corporation’s policy handles common areas, the building envelope, shared systems, and units up to the standard unit benchmark. What it does not cover is your furniture, electronics, clothing, or anything else you own inside your unit. It also does not cover upgrades you have made beyond the standard unit description. If you installed hardwood floors where carpet was specified, or replaced builder-grade countertops with stone, those improvements are your responsibility to insure.
This is why personal condo insurance for unit owners exists, and why most lenders require it as a condition of financing. Beyond the lender requirement, it fills the gap between what the building policy covers and what you actually own and have invested in your space.
There is another layer to this that catches many Alberta owners off guard. Since January 1, 2020, the Condominium Property Regulation allows corporations to recover their insurance deductible from a unit owner when the damage originated in that unit, up to a maximum of $50,000. This applies regardless of whether the owner was negligent. A dishwasher supply line that fails overnight, a toilet that overflows unexpectedly, a hot water tank that gives out while someone is travelling: in these situations, the damage originates in the unit, and the owner can be held responsible for the corporation’s deductible even if they did nothing wrong.
There are specific protections built into the legislation. A corporation cannot charge back the deductible when the damage was caused by a construction defect, by an act or omission of the corporation itself, or by normal structural deterioration of common property. But outside of those exceptions, the rule is broad, and it applies.
Carrying personal condo insurance that includes deductible coverage up to the amount of the corporation’s deductible is the most straightforward way owners protect themselves here. The corporation is required to notify owners when its deductible amount changes, so that owners can adjust their coverage accordingly.
The situation in Calgary right now also raises a less familiar issue. Standard personal condo insurance policies in Alberta typically exclude overland water flooding, meaning water that enters from the ground level due to heavy rainfall, rising rivers, or overwhelmed drainage systems. This is not covered by default. It requires a specific endorsement or add-on to the policy.
This is worth understanding clearly: even if you carry personal condo insurance, you may not be covered for water that enters your unit because a heavy rain event saturated the ground or overwhelmed infrastructure outside the building. If your unit is on a lower floor, in a building with below-grade parking or storage that connects to your space, or in an area where drainage has historically been a concern, it is worth reviewing your policy terms with your insurance provider.
The corporation’s master policy may cover certain types of water intrusion depending on how the damage occurred and where it originated. What matters is the source of the water and how it moved through the building. Those details determine which policy responds and whether there is any gap between them.
Water damage is one of the most common sources of condo insurance claims in Alberta, and Calgary is no exception. Hail, spring runoff, and the occasional extreme rain event like what the city is experiencing right now can push water into buildings in ways that are difficult to predict or prevent entirely. The layers of coverage, the SIUD, the deductible chargeback rules, and the exclusions for overland flooding create a picture that is more complex than most people realize when they first purchase a unit.
For boards, understanding these layers matters because it affects how claims are handled, how bylaws are written, and how clearly owners are informed about their own obligations. For owners, it matters because gaps in personal coverage can become very expensive very quickly.
Alberta’s condo insurance framework is designed to ensure buildings are protected at a meaningful level. Knowing where the building policy ends and where personal responsibility begins is what makes the system work the way it was intended.
