Mixed-use development combines different land uses, typically residential and commercial, within the same building or area. A mixed-use building might have retail stores at street level with apartments above. Mixed-use zoning allows this combination where traditional single-use zoning would separate homes from businesses. Urban planners increasingly favour mixed-use development because it creates walkable neighbourhoods, reduces car dependence, supports local businesses, and uses land efficiently. Municipal zoning bylaws define which areas permit mixed-use development and what combinations are allowed. Mixed-use districts are common in downtown cores and along transit corridors where higher densities and diverse activities are encouraged.
