Find out if you need planning permission or building regulations
You may need permission if you want to:
- build something new
- make a major change to an existing building for example an extension
- change the use of a building
However the rules that govern whether planning permission or building regulation approval is needed are quite complex. There is an extremely helpful interactive guide within the pages of the Planning Portal website that provides guidance on the permitted development limits for residential property.
There are many kinds of alterations and additions to houses that do not need planning permission - this is called permitted development. Use the interactive house on the Planning Portal website to see if you think this applies to you.
Whether you require planning permission relies on a number of factors:
- The size and position of the alterations
- The size of your house
- Whether the house is terraced, semi-detached or detached
- Whether you live in a Conservation Area
- Whether there are special planning controls in your area
- Whether the house has been extended before
- Whether you have outbuildings in the garden
- The proximity of your curtilage boundaries to the extension
Each individual circumstance is different so we strongly recommend that you get advice from us that takes your specific location and circumstances into consideration. The best way to do this is by using the householder enquiry form. (The downloadable version is here). We aim to respond to these requests within 10 working days.
