For an initial assessment, the existing business registration documents and previous letters from authorities are particularly useful. Briefly describe the services actually offered, such as accommodation, breakfast, restaurant services, events or leisure activities.
For an operating facility, rooms, equipment, opening hours, visitor numbers and emissions may matter. Put existing operating descriptions, submitted plans, decisions and conditions in one chronological file. Whether an approval is required or which authority is responsible can only be assessed from the actual facility and its use.
Make changes visible as well. Add renovation plans, new equipment, extensions of the offer and authority questions in date order. This shows whether the issue concerns the existing business or a planned change.
