The City of Vancouver — Canada’s only city with its own building code — is mandating that new doors be fitted with lever-handles instead of doorknobs. The move is intended to increase accessibility — a doorknob requires substantially more dexterity and strength than a lever — but it will also make things easier for people with full hands. Doorknobs will remain in use for decades in Vancouver, of course (housing stock has a long shelf-life), but over time, they will dwindle away to historical curiosities. (via Hacker News)
