Renovating a Condo or Townhouse in BC: What Needs Strata Approval

Paint doesn't need anyone's permission. Flooring almost always does. That gap surprises more first-time condo and townhouse owners than any other renovation rule in BC, and it's usually discovered mid-project, after the materials are already ordered.

We've had the conversation with buyers who assumed a renovation was purely their own business because it happens entirely inside their unit. In a BC strata, that assumption is wrong more often than it's right. Here's how the approval process actually works, and why one specific renovation causes more disputes than everything else combined.

The legal starting point: written approval, not a courtesy heads-up

Under BC's Strata Property Act, the standard bylaws that apply to most stratas require an owner to get written approval from the strata corporation before altering a strata lot, and separate written approval before altering common property, including limited common property (BC Laws, Strata Property Act Standard Bylaws). This isn't a courtesy notification. It's a formal requirement, and a strata can't unreasonably withhold approval, but it can attach conditions.

Every strata customizes these standard bylaws to some degree, so the exact rules in your building may be stricter or more detailed than the template. The only reliable way to know what applies to you is to read your specific strata's current bylaws, not assume they match a generic BC standard (Province of BC).

What usually doesn't need approval

Cosmetic changes that don't touch anything the strata insures or anything shared tend to clear the bar without formal sign-off. Repainting interior walls, swapping a light fixture for a similar one, replacing cabinet hardware, these are the kinds of changes most stratas leave alone. The theme running through what doesn't need approval is that it stays entirely within your own decorating choices and doesn't touch plumbing, electrical, structure, or anything the strata's insurance policy is required to cover.

What almost always needs approval

Flooring changes, particularly anything replacing carpet with a hard surface, sit at the top of this list, and we'll come back to why in a moment. Anything touching plumbing or electrical behind walls needs approval, since that work affects systems the strata may be required to insure. Structural changes, removing or altering a wall, obviously require approval and typically an engineer's sign-off as well. Balcony or patio alterations usually count as common property or limited common property, which means separate approval under the common property bylaw rather than the strata-lot bylaw.

Kitchen and bathroom renovations almost always land in this category too, even when the layout doesn't change, because they typically touch plumbing and electrical at minimum.

The Alteration Agreement, and what it actually contains

When a renovation needs approval, the strata typically documents it through an Alteration Agreement, a written agreement between the owner and the strata corporation that spells out the approved scope of work, sometimes requires proof of contractor insurance and qualifications, and usually makes the owner responsible for any costs or damage related to the work. The strata council reviews and signs it before work starts, and it becomes part of the building's permanent records, which matters later if you sell and a future buyer's strata search turns up the approved alteration.

Plan for roughly 4 to 6 weeks from a complete application if your strata council can approve the request directly. Some stratas, particularly for larger alterations, require the request go before all owners at an annual or special general meeting instead of just council, which can add another 2 to 4 months depending on the calendar. Submit early, and submit with a complete scope, contractor details, and any documentation the bylaws ask for, rather than a vague description that bounces back with questions.

Why flooring is the renovation that causes the most disputes

Hard flooring transmits impact noise, footsteps, a dropped phone, a chair scraping, to the unit below far more than carpet absorbs it. In a multi-unit building where someone's floor is someone else's ceiling, that difference is the single most common source of neighbour-to-neighbour noise disputes, and it's why so many BC stratas either restrict hard flooring outright or require specific underlay.

Two measurements come up in these bylaws: Impact Insulation Class, which rates how well a floor assembly reduces impact noise like footsteps, and Sound Transmission Class, which rates resistance to airborne sound like voices and music. A strata bylaw might require flooring to meet a minimum IIC rating with a specified underlay product, and installing hardwood without meeting that standard is exactly the kind of unauthorized alteration that generates a formal complaint.

BC has seen real disputes over this. Cases exist where an owner installed hardwood flooring, received a formal noise complaint from the unit below, and was ultimately ordered to remove the wood flooring and reinstall carpet, at the owner's own expense, after a finding that the flooring breached the strata's nuisance bylaw. That's the outcome worth avoiding, and it's entirely avoidable by getting flooring specifically approved, with the right underlay, before installation rather than after a complaint.

What a straightforward approval actually looks like

Most renovations don't end in a dispute. A typical, well-handled kitchen update looks something like this: the owner drafts a scope of work with their contractor, submits it to the strata council along with proof of contractor insurance, and the council reviews it at the next regular meeting. If the work stays within the unit's boundaries and doesn't touch structural elements, council can usually approve it directly and issue a signed Alteration Agreement within a few weeks.

The friction shows up when the request is vague, "updating the kitchen" without specifics, or when the work touches something the strata needs a professional opinion on, like moving a load-bearing element. Giving the council a complete, specific scope up front is the single biggest thing an owner can do to keep the timeline on the shorter end.

If a dispute happens anyway

Even with approval in hand, a renovation can still generate a noise complaint once it's done, particularly with flooring. If a neighbour complains, the strata typically investigates, which can include acoustic testing to confirm whether the installed flooring actually meets the required rating. If it doesn't, and there wasn't a valid Alteration Agreement covering the specific underlay used, the owner can be asked to fix it retroactively, sometimes years after the original work.

This is exactly why keeping records matters. Save the signed Alteration Agreement, the underlay product specification, and any installer documentation confirming the IIC rating. If a complaint comes years later, being able to show the work was approved and met spec is the difference between a quick resolution and a drawn-out dispute.

Bare-land strata townhouses work a little differently

The approval principle is the same in a bare-land strata, written approval before altering common property or anything the strata insures. What changes is the scope of what counts as common property in the first place. Conventional strata condos typically have the corporation owning and insuring the building exterior, which means exterior changes almost always need approval. Bare-land stratas often insure and own less of each individual building, sometimes just the land and shared common structures, which can put more of the physical building itself, and more renovation decisions about it, within an individual owner's control.

That doesn't mean bare-land strata owners can skip the approval question altogether. Exterior paint colour, changes to windows or doors visible from the street, and anything affecting the building's roofline or envelope often still require sign-off even in a bare-land structure, since most bare-land stratas maintain design-consistency bylaws across the complex even where they don't own the buildings outright. Confirm with your specific strata rather than assuming bare-land automatically means fewer restrictions.

Timing this before you buy, not after

If you already know you want to change the flooring or take on a bigger renovation, the smart window to check is during your subject-removal period, not after you own the unit. Ask to see the strata's alteration and renovation bylaws, and if possible, recent Alteration Agreements the strata has approved, so you know both what's allowed and roughly how the approval process has gone for other owners in the same building.

This pairs directly with the broader document review we recommend before every purchase. Our strata documents review checklist covers what else to request, and our strata bylaws vs rules guide explains the practical difference between the two, since renovation restrictions typically live in the bylaws, not the rules, which matters for how they're enforced and changed.

What we'd tell a friend planning a renovation

Read your building's specific alteration bylaws before you order materials, not after. If flooring is part of the plan, ask about the underlay requirement and IIC rating up front, since that single detail is what separates an approved renovation from a dispute. And submit your Alteration Agreement request as early as the timeline allows, since a general-meeting requirement can turn a six-week wait into a six-month one.

None of this is meant to discourage renovating. Most BC stratas approve reasonable, well-documented requests without much friction. The disputes happen when the work starts before the paperwork does.

It's also worth thinking about resale, even if selling is years away. A buyer's realtor and lawyer will typically request the strata's records during their own due diligence, and an unauthorized alteration that surfaces there can complicate or delay a sale down the road. Approved work with a clean paper trail is a non-issue. Unapproved work is a question you'll have to answer eventually, one way or another.
