1. Rights and benefits protection measures: In order to protect the heritage and environmental values of the historic building, an assessment is required to ensure that the catering business will not cause damage to the building. This stage usually requires communication with the cultural heritage authorities to understand the level of protection the building is under and the range of activities that can be carried out.
2. License application: An application for a catering license needs to be submitted to the relevant local government authorities. The application form and required documents may vary, and documents regarding operator identification, food safety certificate, business registration certificate, etc. may be required.
3. Health License: An application for a health license needs to be submitted to the health supervision department. This certifies that the food premises meets food safety and hygiene standards and ensures the safety of the food provided to consumers.
4. Building Alteration Permit: If the food premises needs to carry out works such as building structure alteration, renovation or extension, it may be necessary to apply for a Building Alteration Permit from the Urban Planning Bureau or Building Management Department.
Please note that the above only lists some general approval processes. For specific approval requirements for opening a restaurant in a historic building, you will need to consult with the relevant local authorities, such as the municipal government, cultural heritage administration, public security bureau, health supervision department, and so on. They will be able to provide accurate information and guidance and tell you which departments you should submit your application and documents to.
