Not all businesses can open restaurants on the property certificate, and not all houses for commercial purposes can open restaurants, because restaurants involve environmental problems and must be approved by the local environmental protection department. Commercial houses include ordinary houses, commercial and residential buildings, villas, office buildings, commercial facades, shops and other commercial houses, which refer to commercial finance, catering tourism and other business service buildings, as well as their corresponding ancillary facilities, that is, the maximum service life of shops and land is 41 years. It mainly depends on the planned use of the house, that is, the planned use indicated in the real estate license or the description of the use column on the real estate certificate. If it is determined to be commercial, it depends on the format of the building and whether it can meet the requirements of catering services in combination with the requirements of the residential property.
