Who's Responsible? Strata vs Owner Repairs and Maintenance in BC

The line between what your strata must repair and what falls on you as an owner is often blurry. A plain-English guide to who's responsible in BC stratas.

It usually starts in the building chat: water is dripping through a ceiling, a window won't latch, or the deck boards are rotting — and before anyone asks how do we fix this, someone asks who pays for it? In a BC strata, that second question is one of the hardest to answer cleanly, and getting it wrong strains both budgets and goodwill. Here's how strata vs owner responsibility actually works in BC, why the line is so often blurry, and how a small building can settle the grey areas before they turn into disputes.

Common property vs your strata lot

Almost every repair question comes down to one distinction: is the thing that needs fixing common property or part of an individual strata lot?

Under the BC Strata Property Act, the strata corporation has a duty to repair and maintain common property and the common assets it owns on behalf of everyone. That's the shared skeleton of the building — roof, foundation, exterior walls, the pipes and wiring running through common areas, hallways, the parkade, the boiler, shared landscaping. It's funded collectively, which is a big part of what your strata fees cover.

Everything inside the boundary of your own strata lot is generally your responsibility as the owner — your flooring, cabinets, appliances, paint, and the fixtures you use day to day. The strata doesn't repaint your living room or replace your dishwasher, and your fees don't fund those things.

Simple enough in theory. The trouble is that a building isn't neatly sorted into "shared" and "private" — the two are physically interwoven, and the boundary often runs right through the walls.

Where the line actually sits

A useful rule of thumb is that the boundary of your lot sits near the midpoint of the structural wall, floor, or ceiling separating you from the next lot or from common property — though your registered strata plan governs, and it can define boundaries differently. In plain terms:

The finished surfaces you can see and touch inside your unit are usually yours.
The structure and systems behind them — studs, concrete, and the pipes and wires feeding the whole building — are usually common property.

So a leaking tap or a cracked tile inside your unit is typically an owner problem. A failed common pipe inside the wall that leaks into your unit is typically a strata problem — even though the water shows up in your kitchen. That's why "it happened in my unit, so it's mine" and "it's the building's pipe, so it's theirs" are both incomplete: the source of the failure usually matters more than where the damage appears. When a wall gets opened up, document what actually failed.

Limited common property: the classic grey zone

The murkiest category is limited common property (LCP) — common property that only one or a few lots may use, like a balcony, patio, designated parking stall, or in some plans the windows and doors on your unit. It's shared property with your name informally on it, which is exactly why responsibility gets confused. (We go deeper in common property vs limited common property.)

Under the Standard Bylaws, responsibility for LCP is typically divided: the owner who benefits handles routine upkeep, while the strata handles the bigger, less-frequent repairs to the structure and exterior. So you might keep your balcony clear, but the strata deals with the membrane, railing, or slab beneath it. Windows and exterior doors are a common flashpoint — some buildings treat them as a strata job, others push more onto owners.

The key point: the Standard Bylaws are only a default. Many BC stratas have amended their bylaws to shift these responsibilities, and those amendments (once properly filed) generally control. So before you argue about who fixes a balcony door, read your building's actual registered bylaws — not the generic version, and not what someone remembers from their last building. If yours seem to conflict with the Act, it helps to understand which strata bylaws actually hold up.

When an owner alters something, they usually own it

Here's a boundary that trips up owners in small buildings: if you change common property or LCP — building a deck, adding a heat pump, enclosing a patio, or swapping flooring in a way that affects sound — you almost always need the strata's written permission first, and you're typically asked to sign an agreement taking on responsibility for that alteration going forward.

That agreement (often called an alteration or assumption-of-liability agreement) means the original thing may have been the strata's job, but your version of it — plus future repairs and often the damage it causes — becomes yours, and usually passes to whoever buys your unit next. It's one of the most common ways a strata responsibility quietly converts into an owner responsibility, and it's worth understanding as part of your rights as a strata owner.

Insurance and the deductible curveball

Even once you've sorted out who repairs what, insurance adds a layer — because the strata's coverage and the repair rules don't line up perfectly.

The strata must insure the building and common property against major insurable perils, and that policy usually also covers the strata lots to their original standard (roughly, how they were built, not your later upgrades). That's why owners are strongly encouraged to carry their own condo owner's insurance — it fills the gaps, including your betterments, contents, and personal liability.

The part that surprises people is the deductible. When the strata makes a claim, it pays a deductible that can be substantial, and in some cases it may recover that deductible from the owner whose lot the loss originated from — sometimes even without clear negligence. This is a nuanced area of BC strata law, so if a claim is on the table, read up on water damage and the strata deductible and confirm the specifics with your insurer and a strata lawyer.

This article is general information about the BC Strata Property Act framework, not legal, insurance, or financial advice. Every building's strata plan, bylaws, and policy differ, and the rules change. Confirm your building's specifics with your registered bylaws, your council or manager, and a qualified professional.

How a small strata should handle the grey areas

In a building under 150 units, you rarely have a big committee or in-house expertise to referee these calls — which makes a clear, consistent process worth more than a perfect one:

Write it down. A simple responsibility chart, built from your actual bylaws and strata plan, stops the same argument recurring every time something breaks.
Diagnose before you assign. Find out what physically failed, and where the boundary sits, before deciding who pays — open the wall, take photos, get a trades opinion if needed.
Fix urgent safety and water issues first, sort the bill second. Delaying a repair to win an argument usually makes the damage, and the cost, worse.
Keep records. Council minutes, alteration agreements, and repair invoices protect both the owner and the strata when a boundary question resurfaces years later.

When responsibility is genuinely unclear or the dollars are large, get a strata lawyer's read rather than letting the council guess. A wrong call on who pays can cost far more than the advice.

Frequently asked questions

If a pipe bursts inside my wall, is it the strata's problem or mine? It depends on whether the pipe is common property or part of your strata lot, which your strata plan defines — pipes serving the whole building are usually the strata's, while lines serving only your unit are often yours. Where the water ends up doesn't decide it; the source and the boundary do. Confirm what actually failed before assigning the cost.

Who is responsible for windows and balconies in a BC strata? Windows, doors, and balconies are frequently limited common property, and under the Standard Bylaws responsibility is usually split — owners handle routine upkeep, the strata handles major structural and exterior repairs. But many stratas amend these bylaws, so your building's registered bylaws are what actually govern.

Can our strata make owners responsible for things the Act assigns to the strata? To a degree, yes — stratas can amend the Standard Bylaws to reallocate certain repair responsibilities, and properly filed amendments generally hold. But bylaws can't override the Act's core duties or be applied unfairly, and some shifts don't stand up. If unsure, have the bylaw reviewed by a strata lawyer.

Does the strata pay to repair damage inside my unit after a common-property leak? Not automatically. The strata fixes the failed common element, but restoring your unit's interior often runs through insurance, and a deductible may land on the responsible owner. This is why your own condo insurance matters.
