If planning permission was granted to run a business from a residential premises over 15 years ago (retrospective application due to enforcement proceedings) and that permission contained specific conditions regarding usage, limits of vehicles, sheds / buildings they can erect, parking places etc, what happens if the business has been ignoring these conditions? I assume it would need to be reported to the council who would then need to take enforcement action?
What happens if the business has been ignoring them for at least 6 years, maybe even longer - is there something similar to the 4 year rule or does that not apply because they are conditions of the planning permission?
