The detail.
B8 includes open-air storage. A property combining storage, retail, manufacturing or other activities may need a closer assessment of its principal and ancillary uses.
This guidance applies to England. The lawful use, conditions, any proposed works and the facts of the operation should be checked for each property.
What to check.
- Check the lawful use, any conditions and the permitted use in the lease.
- Consider vehicle access, loading, servicing, hours and external storage.
A planning adviser or the local planning authority can advise on the specific property and proposal.
