Nanjing neighbor's bedroom was compensated for changing the toilet. Which departments need to agree to the house decoration?

For many people, it is a happy thing to finally buy a nest for themselves after working hard for most of their lives. However, in the process of decoration, we don't understand the knowledge of decoration, which leads to chaos in many places, not only for ourselves, but also for our neighbors.

Just some time ago, in Nanjing, there was a disorderly renovation, which brought great trouble to neighbors and themselves. The cause of the incident was that Mr. Wang of Nanjing bought Room 403 in a residential area in Qinhuai District of Nanjing. When he checked in, he often heard the sound of drainage upstairs, and he often smelled that smell. Later, after asking Mr. Zhang, the owner of Room 503, I learned that Mr. Zhang changed his bedroom into a bathroom during the renovation, so this led to the downstairs bedroom of Room 403 being able to hear the sound of the upstairs bathroom draining.

Mr. Wang, the owner of Room 403 downstairs, is extremely uncomfortable. Because of the upstairs decoration, his bedroom leaked water, which affected their normal life. So Mr. Wang sued the Qinhuai court, demanding that Mr. Zhang restore the layout of the bathroom in Room 503 to its original state, and compensate for the house repair costs and related rental costs of more than 7,000 yuan. Therefore, through this matter, we must first ask about the knowledge of decoration when decorating, so as not to cause similar incidents. Which departments need approval for house decoration? House decoration belongs to the approval process of housing management, reconstruction or expansion of local housing management department, including acceptance, preliminary examination, audit and approval and certification, so when we decorate the house, we must first get the approval of the housing management bureau before we can decorate it. The applicant for house decoration shall go through the construction application formalities with the approval letter to the construction administrative department, and the decoration can be carried out only after obtaining the construction permit. Moreover, when we decorate the house, we should follow the relevant regulations on the supervision and management of engineering construction quality and safety. Go to the quality and safety supervision department where the project is located to handle the quality and safety supervision procedures for architectural decoration projects.
