Can I remove a load-bearing column in my Metro Vancouver basement?

You cannot simply remove a load-bearing column in your Metro Vancouver basement — it must be replaced with an engineered alternative such as a steel beam, laminated veneer lumber (LVL) beam, or a reconfigured support system designed by a licensed structural engineer. Removing a load-bearing column without proper engineering is extremely dangerous and violates the BC Building Code.

Load-bearing columns in basements carry the weight of the floors, walls, and roof above them down to the foundation. In most Metro Vancouver homes — from post-war bungalows in Burnaby to Vancouver Specials in East Vancouver — the main beam runs the length of the house and is supported by one or more steel Lally columns or wood posts. Removing even one column without transferring that load creates a serious structural failure risk, including sagging floors, cracked walls, and in the worst case, collapse.

The solution is beam replacement or upgrade, not simply removal. A structural engineer will calculate the loads and design a new beam — typically a steel W-shape or built-up LVL — that spans the distance between remaining supports without needing the column you want to eliminate. The new beam must be sized to carry the full tributary load, and in Metro Vancouver's seismic zone, the engineer must also account for earthquake forces in the design. This seismic requirement adds complexity that homeowners in non-seismic regions do not face.

What the Process Looks Like

First, hire a licensed structural engineer in BC — expect to pay $1,500 to $4,000 for the engineering design and sealed drawings. The engineer will assess the existing structure, determine the loads, and specify the replacement beam size, connections, and any new footings required. You will need these sealed drawings to obtain a building permit from your municipality — the City of Vancouver, Burnaby, Surrey, and all other Metro Vancouver municipalities require permits for structural modifications.

The construction typically involves installing temporary shoring to support the load while the column is removed and the new beam is installed. A steel beam capable of spanning 15 to 20 feet without intermediate support might be a W10x26 or larger, weighing several hundred pounds — this is not a DIY project. The beam must bear on adequate footings at each end, which may require excavating and pouring new concrete pads. Total cost in Metro Vancouver ranges from $5,000 to $15,000 depending on span length, beam size, footing requirements, and whether the work involves cutting into the concrete slab.

After installation, your municipality will require a structural inspection before the work can be concealed with drywall. The engineer may also need to provide a field review confirming the work matches the design. Keep all permits and engineering documents — they are critical for insurance purposes and when you sell the home.

One important consideration for strata townhomes across Metro Vancouver: if the column is within a common property area or supports a shared structure, you will need strata council approval before proceeding. The strata may require their own engineer to review the proposal, and they can deny the request if it affects the building's structural integrity.

This is specialised work that requires both an engineer and an experienced contractor.
