- if an area is being used to park company vehicles
- if an area or building is being used store equipment or stock
- checking the opening times of a building, site or business are legal.
This can be useful if you are trying to sell land but find out that planning permission was never granted and you want to show any potential buyers that the action or business taking place is lawful. You do, however, need to provide evidence to show the use or works have been in place for at least 10 years.
