British Columbia looks to change building code to develop single-stair apartment buildings

B.C. will look at changing its building code to allow small apartments to be built with a single stair, adding to its reputation as the province most willing to try new ideas to create more housing supply, though the move is also drawing safety-related concerns.Canada’s building code, which provinces have generally gone along with, has required two staircases per apartment building since 1941. But B.C.’s Ministry of Housing last week published a research report outlining the optimal conditions for single staircases.
