Most cities require that fences not exceed 1.8 meters in height, but the specific height may vary depending on the region and type of housing. The height of fences for typical residences is generally between 1.8 and 2.2 meters, while the height of fences for villas or detached houses may be between 2 and 2.5 meters. However, some areas may have stricter regulations, limiting fence heights to 2.2 meters or lower. The height of the fence must comprehensively consider factors such as privacy, security, and aesthetics, avoiding excessive heights that create a sense of oppression or excessively low heights that compromise privacy.
The openwork ratio of the fence must reach a certain proportion to ensure transparency. Some areas allow the use of hedges instead of solid walls, but the height of the plants is also restricted. The material, style, and color of the fence must also comply with local policy requirements; for example, certain historical and cultural districts or key scenic areas have special requirements for fences.
