There are two ways to solve this situation:

First, according to the management regulations of various cities, street shops have unified requirements, and the height, specifications, text and content of facades and billboards have unified requirements. As you said, if the specifications exceed, it will affect the city appearance, and secondly, it will affect the residents upstairs and reflect it to the urban management (if it is the main block, it can be solved within one week);

Two, according to the provisions of the "General Principles of Civil Law" and "Code for Planning and Design of Urban Residential Areas":

1, Article 89 of the Property Law: 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.

2. Article 83 of the General Principles of Civil Law: Adjacent parties to real estate shall correctly handle the adjacent relations such as water interception, drainage, ventilation, transportation and lighting in the spirit of facilitating production, life, solidarity and mutual assistance, and fairness and reasonableness. If losses are caused to the neighboring parties, the infringement shall be stopped, the obstruction removed and the losses compensated.

3. People's Republic of China (PRC)'s Code for Planning and Design of Urban Residential Areas (GB50 1 80-93-93) (hereinafter referred to as the Code) stipulates: "The sunshine standard for residential buildings in big cities is more than 2 hours in severe cold days, winter to day1hour, and the residential buildings for the elderly should not be less than 2 hours in winter to day; Adding any facilities outside the original design building should not reduce the adjacent original sunshine standard; The sunshine standard for new residential buildings in old district reconstruction projects can be reduced as appropriate, but it should not be lower than the standard of cold weather sunshine time 1. " This standard should be the main basis for judging whether the dispute over lighting rights constitutes infringement at present.

According to the above situation, if it affects your lighting and ventilation, you can apply to the court for civil litigation compensation.

I hope it helps you.
