A commercial district or commercial zone is any part of a city or town in which the primary land use is commercial activities (shops, offices, theaters, restaurants and so on), as opposed to a residential neighbourhood, an industrial zone, or other types of neighbourhoods. In some cities, authorities use planning or zoning laws to define the boundaries of commercial districts.
