Enclosing a Balcony in a BC Strata: Why It Is Harder Than It Looks

Glassing in a balcony turns a seasonal space into a year-round room, which is genuinely appealing in a Fraser Valley condo. It also alters the outside of a building you share with everyone else, and that is why the approval path is longer than buyers expect.

Your balcony is probably not yours

In most BC stratas a balcony is limited common property.

The Government of BC's page on common property and limited common property explains the category: common property designated for the exclusive use of one or more strata lots. You have exclusive use of it. The strata corporation still owns it.

Our limited common property guide covers how this plays out for parking and storage too, and the logic is identical. Exclusive use is not ownership, and altering it is altering someone else's property.

Why this needs a vote, not just a form

Under section 71 of the Strata Property Act, a change to common property that results in a significant change in use or appearance requires a resolution passed by a 3/4 vote at an annual or special general meeting.

A balcony enclosure is close to the clearest example of that. Open air becomes glass, visible from the street, on a building where every other unit has an open balcony. Both the use and the appearance change.

The Standard Bylaws add the other layer: an owner must not alter common property or limited common property without the written approval of the strata corporation, and the strata may require the owner to agree in writing to take responsibility for expenses relating to the alteration. Our AGM and SGM guide covers when those meetings happen, which matters because the timing is not yours to choose.

Why councils are cautious

It helps to understand the objection rather than treating it as obstruction.

An enclosure sets a precedent. Approve one and the strata has to think about the next twelve requests and what the building looks like when half of them are done and half are not. Councils also worry about the building envelope, because glass and framing added to an exterior wall is a new place for water to get in. Our leaky condo and rainscreen guide covers why BC stratas are careful about envelope changes.

Then there is the long-term question. In twenty years, who repairs the enclosure? Who pays when the building does envelope work and the enclosure is in the way? That is what an alteration agreement is for.

The municipal layer

An enclosure may add floor area, and floor area brings building code and permits into the picture.

That is a conversation with your municipality, separate from the strata approval. Both can say no independently, and getting one does not get you the other. Our renovating a condo guide covers the general approval sequence.

Do not assume a contractor is handling permits. Ask who is pulling them and see the paperwork.

If the unit already has one

This is the common situation, and it is the one where a buyer has real exposure.

Ask for four documents during your subject period: the written strata approval, the general meeting resolution if one was required, the alteration agreement, and any municipal permit. Our strata documents checklist covers the wider review, and this belongs in it.

If those do not exist, you may be buying an unapproved alteration to common property. A strata can require it to be removed or brought into compliance, and that obligation does not stay with the seller. The same logic applies to an unpermitted suite or undocumented electrical work: work without paperwork is work nobody signed off on.

Check the council minutes too. If the strata has been corresponding with an owner about an enclosure, it will be in there.

Insurance and measurement

Two smaller points worth knowing.

Section 149 of the Act requires the strata to insure common property, common assets, buildings shown on the strata plan, and fixtures built or installed by the owner developer. An owner-added enclosure is not a developer fixture, which is part of why the alteration agreement matters. Our condo insurance guide covers the split between the two policies.

And an enclosed balcony does not automatically change the unit's measured area on paper. Our square footage guide covers how BC condos are measured, which is worth reading before you price a unit on the basis of its enclosed space.

What we tell buyers

If the enclosed room is the reason you want the unit, verify the paperwork before you remove subjects. If your plan is to enclose it later, understand that you are depending on a future vote of your neighbours, and that vote can fail.

In our experience the buyers who get caught here are the ones who treated the enclosure as a feature of the home rather than as an alteration with a compliance history. It is both, and only one of those is checkable.

We are agents rather than lawyers or engineers, and none of this is legal or technical advice. Your lawyer or notary, the strata corporation, and your municipality are the right sources for a specific unit.

Key takeaways

• A balcony is usually limited common property: your exclusive use, the strata's property.
• Section 71 of the Strata Property Act requires a 3/4 vote for a significant change in use or appearance of common property.
• The Standard Bylaws require written strata approval and may require an alteration agreement.
• An enclosure may add floor area, bringing municipal permits and building code into play.
• On a unit that already has one, ask for the approval, the resolution, the alteration agreement, and the permit.

Frequently Asked Questions

Is my balcony mine?

In most BC stratas, the strata corporation owns the balcony. It is usually limited common property: common property set aside for the exclusive use of your strata lot. You use it day to day, but the strata corporation still owns it, the same way it owns other limited common property like assigned parking or storage. That ownership structure is why enclosing a balcony needs strata approval, and often a 3/4 vote.

Do I need a 3/4 vote to enclose a balcony?

Yes, in most cases a 3/4 vote is required to enclose a balcony in a BC strata. Under section 71 of the Strata Property Act, a change to common property that results in a significant change in use or appearance requires a resolution passed by a 3/4 vote at an annual or special general meeting. Glassing in a balcony changes both the use, from open air to an enclosed room, and the appearance, since it is visible from outside the building. The Standard Bylaws add a separate requirement for written strata approval on top of that vote.

Why would the strata refuse?

A strata council may refuse a balcony enclosure request for several practical reasons rather than out of simple obstruction. Approving one enclosure sets a precedent, since the council then has to think about the next twelve requests and what the building looks like once half of them are done and half are not. The change is also visible from outside the building, which affects every owner's view of it. Councils worry too about the building envelope, since new glass and framing on an exterior wall is a new place for water to get in, and about who maintains that glass twenty years later.

Does enclosing a balcony add floor area?

It can, and when it does, building code and municipal permit questions join the strata approval process. Turning an open balcony into an enclosed room is the kind of change that can count as added floor area under a municipality's rules, which is a separate decision from the strata corporation's. You need to speak with both your municipality and your strata council, and either one can refuse. Approval from one does not guarantee approval from the other.

What is an alteration agreement?

An alteration agreement is a written agreement in which the owner takes responsibility for a strata alteration, such as a balcony enclosure, and for future expenses relating to it. The Standard Bylaws contemplate the strata corporation requiring one before approving this kind of work, on top of the written approval and any 3/4 vote required under the Strata Property Act. It answers the long-term question councils tend to worry about, like who repairs the enclosure and who pays if the building later needs envelope work near it. Ask to see one before assuming an existing enclosure is properly approved.

What if the unit I want already has an enclosed balcony?

If a unit you are considering already has an enclosed balcony, ask for four documents during your subject period: the written strata approval, the general meeting resolution if a 3/4 vote was required, the alteration agreement, and any municipal permit for the added floor area. Without that paperwork, you may be inheriting an unapproved alteration to common property rather than a legitimate feature of the home. Check the strata's council minutes too, since correspondence about an enclosure often shows up there even when the formal paperwork does not exist.

Can the strata make me remove it?

Yes, a strata corporation can require an unapproved alteration to common property, including an enclosed balcony, to be removed or brought into compliance, and that obligation passes to you when you take title. That is why confirming the written strata approval, the general meeting resolution, the alteration agreement, and any municipal permit belongs in your subject period. Buying a unit with an undocumented enclosure means buying the risk of that removal order along with it.

Does an enclosure affect the strata's insurance?

An enclosed balcony can raise insurance questions for the strata corporation, since section 149 of the Strata Property Act requires the strata to insure common property, common assets, buildings shown on the strata plan, and fixtures built or installed by the owner developer. An owner-added balcony enclosure is not a developer fixture, so it sits outside that standard coverage, which is part of what the alteration agreement is meant to address by putting responsibility on the owner. Ask how the strata's policy treats owner alterations before assuming an enclosure is automatically covered.

Does an enclosure change my square footage on paper?

Not necessarily. An enclosed balcony does not automatically change a unit's measured square footage, because how space is measured for strata purposes and what the registered strata plan shows are separate from what has actually been built on the balcony. That distinction matters if you are considering a unit where a glassed-in balcony is being presented as extra living space, since the official measurement on paper may not reflect that enclosed area at all. Confirm how the space is treated on the strata plan before you price the unit based on its enclosed square footage.

Is it worth pursuing as a first-time buyer?

It can be worth pursuing once you understand what you are buying into. If an existing enclosed balcony is the reason you want a particular unit, verify the written strata approval, the resolution, the alteration agreement, and any municipal permit before you remove subjects. If your own plan is to enclose a balcony later, you are depending on a future 3/4 vote of your neighbours at a general meeting, and that vote can fail. Treat the enclosure as an alteration with its own approval record, and check that record.
