As the summer vacation arrives, many parents are busy with their work and have turned their attention to various interest classes and training courses in the community. Some social people who do not have teaching qualifications are also eyeing this "cake" and using their homes to provide counseling. So can residential quarters offer training courses? Can the training course be held in a residential area? Neither the owner nor the user can change the nature of the house at will, nor can they do business in the house they live in. If they want to change the living nature of the house, they need to get the consent of the interested owners. That is, it can be started, but it must be approved by the interested owner and obtain relevant permission. Article 279 of the Civil Code Restrictions on Owners' Changing the Use of Residential Buildings The owners shall not change the residential buildings into business buildings in violation of laws, regulations and management regulations. If the owner changes the house into a business house, in addition to complying with laws, regulations and management regulations, it shall also be unanimously agreed by the interested owners. Some operators will choose to start classes or run trusteeship in residential areas. The reason why these operators use housing to run classes is mainly to reduce operating costs. In addition to the purchase price, the property management fee and utilities of commercial housing are higher than those of ordinary housing, and the property management fee of housing is usually only half of that of commercial housing. These owners start classes without authorization, and the property can only discourage them. This kind of profit-oriented trusteeship class should go to industrial and commercial registration and apply for a business license in the industrial and commercial department. For those who do not meet the requirements and operate without a license, they can report to the relevant departments.
