Is it illegal for residential uncompleted residential flats to have no property and elevators to have no equipment codes?

According to the policies and regulations I understand, it is not illegal for an uncompleted residential building to have no property elevator. However, according to "Residential Design Standards" and "Regulations on Quality Management of Residential Construction Projects", if the building height of a residential area is high, elevators are usually needed to meet the basic travel needs of residents. Therefore, whether it is illegal or not needs to be judged according to relevant local policies and regulations.

As for the lack of equipment codes, I need to say that the equipment codes in different regions may be different. If the equipment code you refer to refers to the relevant specifications and requirements for the installation and maintenance of construction equipment, it may be illegal to build without the equipment code. Before the implementation of the construction project, the corresponding equipment installation scheme should be formulated according to the local specifications and requirements, and ensure compliance with relevant regulations.

Generally speaking, in the case that there is no property elevator and equipment code in the unfinished residential building, it is recommended that you consult the local real estate management department or related professionals for more specific answers and guidance.
