How wide does a bathroom door need to be for wheelchair access under BC Building Code?

For wheelchair access, the BC Building Code requires a minimum clear opening width of 810 millimetres (approximately 32 inches) for doorways in accessible residential bathrooms, though 36 inches (915 mm) is strongly recommended for comfortable wheelchair passage. The "clear opening" is measured with the door open at 90 degrees, from the face of the door to the opposite door stop — not the rough opening or the door slab width.

This distinction matters more than most homeowners realize. A standard 32-inch door slab, once installed with hinges and a door stop, provides only about 29–30 inches of clear opening — which is too narrow for most wheelchairs. To achieve the 810 mm (32-inch) minimum clear opening, you typically need a 34-inch door slab. To reach the preferred 36-inch clear opening, you need a 38-inch door slab. In Metro Vancouver's older housing stock — particularly post-war homes in Burnaby, North Vancouver, New Westminster, and East Vancouver — bathroom doors are commonly only 24 or 28 inches wide, which means widening the doorway is almost always part of an accessibility renovation.

Widening a bathroom doorway in a Metro Vancouver home typically costs $800–$2,500 depending on the wall construction. If the wall is non-load-bearing, a carpenter can widen the rough opening, install a new wider frame, and patch the drywall in a day. If the wall is load-bearing, you will need a structural engineer to specify a header beam, and the cost rises to $2,000–$4,000 or more. In older Vancouver homes with plaster-and-lath walls rather than drywall, patching and finishing is more labour-intensive and adds to the cost. Always have a contractor assess whether the wall is load-bearing before committing to a plan.

Beyond the door width itself, there are several accessibility details that the BC Building Code and CSA B651 (Accessible Design for the Built Environment) address for bathroom doorways.

Door swing direction is critical. A standard inward-swinging bathroom door is problematic for wheelchair users and can be dangerous in an emergency — if someone falls behind the door, it cannot be opened from the outside. Outward-swinging doors, pocket doors, or barn-style sliding doors are all better options for an accessible bathroom. Pocket doors are especially popular in Vancouver condo and townhouse bathroom renovations where hallway space is limited, though they require enough wall cavity depth to receive the door. A pocket door conversion runs $1,200–$3,000 installed in Metro Vancouver, including framing modifications.

Lever-style door handles are required for accessibility — round doorknobs are difficult or impossible for someone with limited grip strength, arthritis, or reduced hand function. Lever handles can be operated with a closed fist, an elbow, or the side of a hand. Replacing a round knob with a lever handle is a simple $50–$150 job that makes an immediate difference.

Threshold height at the bathroom door should be as low as possible — ideally zero threshold (flush with the floor on both sides). A raised threshold creates a trip hazard and a barrier for wheelchair wheels. If a threshold is necessary for water containment, it should not exceed 13 mm (half an inch) and should have bevelled edges.

Maneuvering clearance on both sides of the door is another BC Building Code requirement that catches many homeowners off guard. A wheelchair user needs space to approach the door, reach the handle, and swing or slide the door open. The code specifies a minimum 1,500 mm x 1,500 mm (roughly 5 feet by 5 feet) turning radius inside the bathroom for a wheelchair. In many older Metro Vancouver bathrooms that measure only 5x8 feet or smaller, achieving this turning radius may require removing the bathtub and replacing it with a curbless shower to free up floor space.

For strata and condo bathroom renovations in Metro Vancouver, remember that widening a doorway in a unit that shares walls with neighbouring units requires strata council approval before any work begins. The strata corporation will want to confirm the wall is not a fire separation or structural element, and may require an engineer's letter. Plan for 4–8 weeks for the strata approval process.

If you are planning for future accessibility rather than immediate need, the smartest approach is to install a 36-inch door now during any bathroom renovation — the incremental cost over a standard door is only $200–$400, and it avoids an expensive retrofit later.
