How many meters away from the subway can there be no houses?

The building requirements around this area are generally divided into special protection zones and controlled protection zones.

According to the "Measures for the Management of Urban Rail Transit Operations", when operating in an urban rail transit protected area, a safety protection plan needs to be formulated, specific to the safe distance between the building and the subway line. This is usually determined by the local urban planning and construction standards.

Take Dongguan City as an example. The scope of protection zones established by Dongguan City includes:

1. Special protection zone: within 5 meters outside the outer edge of underground stations and tunnel structures; above-ground stations and ground stations Within 3 meters outside the outer lines of lines, elevated stations and elevated line structures; within 5 meters outside the outer lines of entrances and exits, ventilation pavilions, cooling towers, substations (stations), helicopter elevators and other building (structure) structures and the vehicle base land area .

2. Control protection zone: within 50 meters outside the outer edge of underground stations and tunnel structures; within 30 meters outside the outer edge of ground stations and ground lines, elevated stations and elevated line structures; entrances and exits, ventilation pavilions, cooling towers, Within 10 meters outside the outer lines of buildings (structures) such as substations (stations) and helicopters and the vehicle base land.
