1. Do I need planning permission?
Most dwellings (excluding flats) have Permitted Development Rights which allow you to do certain small works without applying for planning permission. However sometimes these have been removed or other restrictions apply.
Find out if there are any restrictions on your property preventing you from using permitted development rights.
A previous planning permission may also impose restrictions eg. preventing the conversion of a garage to living accommodation etc. You can view previous decisions by doing a planning search by address.
Business or commercial premises may also do some works, including some changes of use, under permitted development
If your property is listed, you will also need listed building consent for any works.
You may also need to contact Devon Building Control Partnership about Building Regulations Consent for your project.
The following websites are a good source of information about when planning permission is needed:
Gov.UK - when planning permission is required has comprehensive explanations.
Planning Portal - do you need permission has an interactive house, common projects and miniguides that give advice as to when planning permission is needed
Remember that you must have checked (using the first two links on this page above) for any restrictions on your property first.
Formal written confirmation of whether planning permission is required can be obtained by submitting an application for a Lawful Development Certificate for Proposed Use. The fee for this is half of the relevant planning application fee. Apply for this on our Apply for planning permission page
