Analysis on Residential Lighting

The current law with high level (that is, authority) only stipulates that there must be enough distance between houses to ensure the right of lighting.

However, the specific regulations vary from place to place. Generally, institutions that take the lead in formulating local laws and regulations have urban planning departments. You can consult the city planning department in detail. The two hours mentioned upstairs are only the specific regulations of a certain city. For example, in places like Chongqing and Guiyang, do you think two hours of sunshine will violate the right to light? Sometimes there is no sunshine for two hours a day. Therefore, it depends on the relevant regulations formulated by the Urban Planning Bureau according to the data of the meteorological department.

Moreover, generally speaking, cases of violation of lighting rights in China are related to illegal buildings, because now all buildings must be approved by the Urban Planning Bureau, otherwise they may not be built, and those that exceed the planning are illegal buildings. The Urban Planning Bureau will generally consider the lighting rights of nearby residential buildings when planning.

Finally, because you live on the first floor, there is not much sunshine. You should compare your previous sunshine with your present sunshine. To put it bluntly, don't offend others because you made a mistake, don't you think?
