Is it illegal to close the terrace on the top floor?

Legal analysis: it is necessary to communicate with the property management agency and apply to the relevant departments for a construction project planning permit, and obtain the consent of the property service company and the local housing management department, otherwise other owners may report it. You can simply decorate it to rest or dry things, but it is absolutely forbidden to build a sunny room because it is illegal and the terrace belongs to a public area. If it is closed and completely used as a private space, it will cause dissatisfaction of other owners and be prone to disputes or complaints.

Legal basis: Article 21 of the Land Administration Law of the People's Republic of China, the scale of urban construction land shall meet the standards set by the state, make full use of the existing construction land, and do not occupy or occupy as little agricultural land as possible. The overall urban planning, village and market town planning should be connected with the overall land use planning, and the scale of construction land in the overall urban planning, village and market town planning shall not exceed the scale of construction land in cities, villages and market towns determined in the overall land use planning. In the urban planning area, village and market town planning area, the construction land of cities, villages and market towns shall conform to the urban planning, village and market town planning.
