In Chinese mainland, building spacing can be divided into sunshine (forward) spacing, lateral spacing and fire-fighting spacing. Urban planning, especially detailed planning, has strict requirements on building spacing, mainly considering sunshine (north-south building), ventilation, underground pipeline layout and fire protection, and street-facing buildings should also consider the needs of street view.

The calculation method of the minimum spacing between different types of buildings stipulated in the Code for Fire Protection Design of Buildings is very complicated, but it can be roughly summarized as follows: the left-right spacing between multi-storey buildings is at least 6 meters, the spacing between multi-storey buildings and high-rise buildings is 9 meters, and the spacing between high-rise buildings is 13 meters.
Generally speaking, the new urban buildings in Chinese mainland need to strictly abide by the relevant provisions of various building spacing. However, due to historical reasons, the village in the city does not conform to the relevant norms of the city, thus forming a "handshake building" landscape.
