# When is planning permission needed for a change of use?

Canonical source: https://rivermarkproperty.com/guides/planning-use-classes/change-of-use/

It depends on the current lawful use, the proposed use and the planning rules and conditions applying to the property.

## 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.
