The short answer
Under BC's Standard Bylaws, removing a wall inside one condo needs the strata's written approval when the wall is part of the building's structure, when it holds pipes, wires or ducts that are common property, or when the original developer built it. Section 70 of the Strata Property Act applies only to a wall that is the boundary between two adjoining strata lots.
Three questions about the wall
Three items of Standard Bylaw 5(1) can apply to one wall. Each has its own question.
Is the wall part of the structure? Item (a) covers an alteration that involves the structure of a building. We treat a wall as structure when it holds up the floor or roof above it. The Act adds a legal right here. A strata lot is the Act's name for a unit. Under section 69, each strata lot and the common property have a right to vertical and sideways support from every strata lot that is capable of providing it. A wall in your unit that supports the unit above is part of that support.
What runs inside the wall? Item (f) covers common property inside the unit. Under section 1 of the Act, a pipe, wire or duct inside your unit is common property when it is capable of being used, and intended to be used, by another unit or the common property. A drain from the unit above meets that test. Wires and pipes that serve only your unit, inside a wall that stands wholly within your unit, fall outside it.
Did the developer build the wall? Item (g) covers the parts of the unit the strata must insure under section 149. That section names the buildings shown on the strata plan and the fixtures the developer installed, and section 9.1(1) of the regulation counts wall coverings as fixtures. We write every request for an original wall on the basis that item (g) applies.
Where section 70 applies
Section 70 of the Act deals with one type of wall: a wall that is a common boundary between adjoining strata lots, or between strata lots that have been consolidated into one. An owner may remove all or part of it with the strata's prior written approval. The strata must approve unless the removal fails to comply with a building regulation or a municipal bylaw, or interferes with utilities or other services to another unit or the common property.
A wall inside one unit is outside section 70. The request for it is decided under Standard Bylaw 5, which says the strata must not unreasonably withhold its approval and gives no list of grounds for a refusal.
Finding out what the wall does
Two sources tell you whether a wall is structure: the building's drawings and a structural engineer.
The strata holds the drawings. Section 20(2)(a) of the Act required the developer to give the strata all plans that were required to obtain the building permit. Section 4.1(7) of the regulation makes the strata keep them permanently. Section 36 of the Act gives an owner copies within 2 weeks of a request, and section 4.2 of the regulation limits the charge to 25 cents per page.
An engineer reads those drawings and looks at the wall itself. The Standard Bylaws are silent on which documents a council may ask for with a request, so ask your strata what it wants to see.
Our own practice is fixed. When a wall is to come out, we have a structural engineer look at it and put the findings in a signed letter, and we attach the letter to the request. If the wall carries load, the letter comes with the engineer's drawing of the beam and posts that will replace it.
What to put in the request
Describe the wall so that a council member who has never seen the unit can find it on the plan. Include:
Ask the City of Vancouver whether the work needs a building permit. For a wall between two strata lots, section 70(3) requires the owner to give the strata copies of any required building permits. For a wall inside one unit, ask the strata whether it wants a copy.
Ask the strata in writing whether the building has its own bylaw on moving walls, which hours apply to demolition, and how debris must be moved through the building.
- A floor plan showing the wall, with the part to be removed marked and measured.
- The engineer's letter, and the engineer's drawing if the wall carries load.
- Every pipe, wire and duct inside the wall, which unit each one serves, and where each will be moved to.
- What will be done to the floor, the ceiling and the nearby walls where the wall stood.
- The contractor documents your building lists, the planned dates, and how debris will leave the building.
Who repairs it later
Standard Bylaw 8(d) makes the strata responsible for repairing the structure of the building, including where it stands inside a unit. Standard Bylaw 2(1) gives the owner the rest of the unit.
A beam and posts that replace a wall carrying load then hold up the floor above. Ask the strata in writing who repairs them. If you sign an agreement under Bylaw 5(2), you take responsibility for expenses relating to the alteration, and the wording of the agreement decides how far that reaches.
Keep the engineer's letter, the drawings and photographs of the open ceiling in the file for the unit. Section 59(3)(c) of the Act requires the strata to disclose an agreement on alteration expenses on the Information Certificate, the form a strata gives a buyer on request.
How we take out a wall in a condo
We start with the drawings and the engineer, before any price is fixed. A wall that carries load changes the work, the request and the schedule.
Before demolition we look at the age of the building. WorkSafeBC says asbestos was used in BC as a building material until the early 1990s, that nobody can tell by looking whether a material contains it, and that a qualified asbestos professional should complete a survey where it is suspected. In a building of that age we arrange the survey before a wall is opened.
We open the wall in stages. The covering comes off first, so that every pipe, wire and duct can be seen and checked against the request. If something appears that the request left unnamed, we stop, and the owner writes to the strata before that part is touched.
Where the wall carries load, temporary supports go in first. The new beam is installed to the engineer's drawing before the old wall comes out.

Frequently asked questions
How do I find out whether a wall in my condo is structural?
Ask the strata for the building permit plans, then have a structural engineer read them and look at the wall. Section 20(2)(a) of the Strata Property Act required the developer to give the strata all plans that were required to obtain the building permit, and section 36 gives an owner copies within 2 weeks of a request. The engineer's written findings then tell you whether Standard Bylaw 5(1)(a), the structure item, applies to the wall in your condo.
Does section 70 of the Strata Property Act apply to a wall inside one condo?
Section 70 of the Strata Property Act applies to a wall that is a common boundary between adjoining strata lots, or between strata lots that have been consolidated into a single lot. A wall that stands wholly inside one condo is outside that section. The request to remove it is made under Standard Bylaw 5, which requires written approval and says the strata must not unreasonably withhold it.
Does my condo have a legal duty to support the units above it?
Yes. Section 69(1) of the Strata Property Act gives each strata lot an easement, a legal right over another property, for vertical and sideways support by the common property and by every other strata lot capable of providing support. Section 69(3) says the right exists without registration in a land title office. A wall in a BC condo that holds up the unit above is part of that support, and altering it needs approval under Standard Bylaw 5(1)(a).
Do I need strata approval to move a wall that has a light switch in it?
Under the Standard Bylaws, moving a condo wall that holds a light switch needs written approval when the switch is original or its wire is common property. An original switch is an electrical fixture under section 9.1(1) of the Strata Property Regulation, so Standard Bylaw 5(1)(g) applies. Under section 1 of the Strata Property Act, the wire is common property if it serves another unit. A wire that serves only your condo, inside an interior wall, is part of your unit.
Who repairs a beam that replaced a wall in my condo?
Standard Bylaw 8(d) makes a BC strata responsible for repairing the structure of a building, including the parts of it inside a strata lot, and we read a beam that carries the floor above as part of that structure. An agreement signed under Standard Bylaw 5(2) can make the owner responsible for expenses relating to the alteration. Ask the strata to state in writing who repairs the new beam and its posts before you sign.
Does a condo wall need an asbestos survey before it is removed?
A wall in an older BC condo building should be surveyed for asbestos before it is opened. WorkSafeBC says asbestos was used in BC as a building material until the early 1990s and can be present in many areas of older buildings. Its asbestos page says a material cannot be judged by looking at it, and that a qualified asbestos professional should complete the survey. If asbestos is found, a qualified asbestos removal contractor must remove it.
Does building a new wall inside a condo need strata approval?
Under the Standard Bylaws, building a new wall inside a BC condo needs written approval when the work involves anything on the list in Standard Bylaw 5(1). A new wall is fastened through the floor covering, so it alters an original floor covering under item (g), and fastening it into the structural floor or ceiling may involve item (a). The Province's strata housing page says a building's bylaws may require permission for "moving walls".
Do I have to give the strata a building permit for removing a wall inside one unit?
The Strata Property Act requires an owner to give the strata copies of building permits in one case: section 70(3), for a wall that is a common boundary between adjoining strata lots. For a wall inside one BC condo, the Standard Bylaws are silent on permits. Ask the City whether the work needs a building permit, and ask your strata in writing whether its bylaws or alteration agreement require a copy before work starts.
