Is it illegal for the basement light well to extend into the yard?

Legal analysis: it belongs to illegal buildings, and the illegal buildings of light wells are hidden and simple. "Because the illegally built light wells are hidden and easy to be stolen, it has caused the fact that many light wells in residential buildings are occupied." According to the analysis of the relevant personnel of the urban management department, most of the light wells they handled were hidden from construction. If it is not reported by the neighbor or property of the illegal owner, it is difficult for law enforcement officers to find it. Law enforcement officials also pointed out that it is very easy to build illegal buildings in light wells. In addition to the seesaw or the floor, the "wall" part is often simply assembled with stainless steel or aluminum alloy touching the window, and it will not take long to build a "room". Because the construction time is very short, often when the law enforcement department arrives at the scene after receiving the report, the illegal construction has become a fact, and the problem can only be solved through the filing procedure.

Legal basis: Article 293 of the Civil Law of People's Republic of China (PRC) stipulates that the construction of buildings shall not violate the relevant national engineering construction standards, and shall not interfere with the ventilation, lighting and sunshine of adjacent buildings.
