A poorly sized hoistway limits your options. It can restrict your choice of elevator systems or result in unnecessary customization costs. Typical residential hoistways for home elevators Ontario require clear inside dimensions that accommodate both the cab and guide rails, plus allowances for ventilation and code-mandated clearance. Work with your elevator provider early to understand minimum shaft size, pit depth, and overhead requirements. Standard lifts may need about 36"x48" of cab space, but that can vary with Canadian elevators or specialized shaftless designs. Oversizing isn't always better—it can lead to structural inefficiencies—so balance function with footprint carefully.
