The detail.
Changes within the same use class are generally not development. Some changes between classes are permitted by national rights, subject to conditions and sometimes prior approval; others require a planning application.
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 decision notices, conditions and any local restrictions, including Article 4 directions.
- Assess building works, listed building consent, building regulations and lease restrictions separately where relevant.
A planning adviser or the local planning authority can advise on the specific property and proposal.
