What Your Condo Corporation Maintains vs. What's Your Responsibility
The dishwasher leaked and now there's water damage in the unit below. Whose problem is it? The answer usually isn't obvious from the ceiling, it's written into your building's declaration.
Quick answer
In Ontario, section 90 of the Condominium Act, 1998 requires the corporation to maintain the common elements, while each owner maintains their own unit, and section 89 makes the corporation responsible for repairing both units and common elements after most kinds of damage. But the exact boundary of a 'unit' and which shared spaces are 'exclusive-use common elements' (like your balcony or parking spot) is set by your building's declaration under section 91, not by the Act alone, so the same fixture can be the corporation's responsibility in one building and the owner's in another.
belo gives condo property managers and boards a dated, continuous record of every common-element repair and vendor visit, so when a maintenance question turns into a dispute over who was responsible for what, there's an actual timeline to point to instead of competing memories.
A dishwasher hose fails on the fourth floor. Water finds its way through the subfloor and stains a ceiling on the third floor. Two owners, one property manager, and a repair bill nobody planned for, and the first question everyone asks is the same one: whose responsibility is this?
It's one of the most common sources of friction in condo living, and the honest answer is "it depends," but not arbitrarily. Ontario's Condominium Act sets a default framework, and your building's declaration fills in the specifics.
The default rule: corporation maintains common elements, you maintain your unit
Section 90 of the Condominium Act, 1998 requires the condo corporation to maintain the common elements: the building's structure, roof, exterior walls, hallways, elevators, and the shared mechanical, electrical, and plumbing systems that serve more than one unit (Condominium Authority of Ontario; Ontario Condo Law Blog). Section 89 goes further, making the corporation generally responsible for repairing both units and common elements after most kinds of damage, which is why your condo fees fund a building insurance policy that covers more than just the shared spaces.
As the owner, you're generally responsible for maintaining what's inside your unit: interior finishes, appliances, fixtures, and anything you added above the unit's standard, builder-grade finish. That last category, upgraded flooring, custom cabinetry, a renovated bathroom, is treated as an "improvement or betterment." You're responsible for insuring and repairing it yourself, even though it sits inside a unit the corporation otherwise has obligations toward.
Why "it depends on your declaration" isn't a dodge
Here's the part that trips people up: the Condominium Act doesn't draw a single universal line between "unit" and "common element." It leaves your building's declaration, the founding legal document registered when the condo was created, to define those terms for your specific building (Cheadles LLP).
That matters most for spaces that feel private but are legally shared: balconies, terraces, and assigned parking spots. Section 91 of the Act lets a declaration designate these as "exclusive-use common elements," meaning you're the only one allowed to use the space, but the maintenance and repair obligation can be assigned differently than you'd expect, sometimes to the owner even though the space is technically still a common element the corporation owns.
Two condos in the same city, built by different developers, can genuinely have opposite answers to "who fixes my balcony door" because their declarations wrote the boundary differently. If you want a definitive answer for your own unit, the declaration (available from your property manager or in your status certificate, see our guide on what to check before buying a unit) is the actual source, not general advice like this article.
What to do when it's genuinely unclear
- Ask your property manager to point to the specific clause, not just give you a verbal answer. Declarations are long, dense documents, but the relevant section for a specific fixture is usually short and locatable.
- Check whether the item is an "improvement or betterment." If you or a prior owner upgraded it beyond the building's original standard finish, it's more likely your responsibility regardless of where it physically sits.
- Ask what the corporation's maintenance record shows for that item. If the corporation has a dated history of servicing a shared system, that history matters when a dispute over cause (not just location) comes up.
- Don't assume "in my unit" automatically means "my problem." Plumbing and electrical systems that serve multiple units often run through individual units without being that unit's responsibility.
How belo fits into this
belo doesn't decide who's responsible, your declaration and the Condominium Act do that. But most maintenance disputes aren't actually disputes about the law, they're disputes about facts: when something was last serviced, who did the work, and whether it was maintained properly before it failed. belo gives your property manager and board a continuous, dated record of every asset and vendor visit, so when a question like this comes up, there's an actual timeline to check instead of two people's competing memories of who said what.
If you're on a board or work with your property manager and want to see what that kind of record looks like, belo has a public demo built on a real reserve fund study.
This is general information, not legal advice. Maintenance and repair obligations vary by building and are ultimately governed by your specific declaration and by-laws. Confirm your building's actual rules with your property manager or condo counsel.
Frequently asked questions
Who is responsible for common elements in an Ontario condo?
The condo corporation is. Section 90 of the Condominium Act, 1998 requires the corporation to maintain the common elements, which typically include the roof, exterior walls, structure, hallways, elevators, and shared mechanical, electrical, and plumbing systems that serve more than one unit.
What is an owner responsible for maintaining in a condo?
Generally, everything inside the boundary of your unit as defined in the declaration: interior finishes, appliances, fixtures, and anything you added above the building's standard finish, which is treated as an 'improvement or betterment' you're responsible for insuring and repairing yourself.
Who pays for my balcony or parking spot if it's damaged?
It depends on your declaration. Section 91 of the Condominium Act allows a declaration to designate certain shared spaces, like a balcony, terrace, or parking spot, as 'exclusive-use common elements,' meaning only you can use it but the maintenance and repair obligation is spelled out separately, sometimes assigned to the owner even though the space is technically a common element.
What happens if water damage from my unit affects my neighbor's unit?
Section 89 generally makes the corporation responsible for repairing damage to both units and common elements after most insurable events, then the corporation's insurance (and potentially yours, depending on your deductible-by-laws) allocates the cost. Whether you're on the hook personally often comes down to whether the damage originated from something in your unit you were responsible for maintaining, and whether it was properly maintained.
Where do I find the actual maintenance boundaries for my condo?
Your corporation's declaration, the document registered on title when the building was created. It defines what counts as a 'unit' versus 'common elements' and 'exclusive-use common elements' for your specific building. Ontario's Condominium Act sets the default rules, but the declaration can and often does modify them.
