You’ll probably need planning permission if you want to:

  • build something new
  • make a major change to your building, eg building an extension
  • change the use of your building

How do I find out the planning history on a property?

Use our Planning Application search facility to view applications from 1996 to the present. Some applications from 1996 to 2005 may not show any associated documents, therefore please email us at to view, providing the full address and any application reference numbers. 

Planning history prior to 1996 is not available online. You will need to email us as above, with the full postal address and any associated details such as application reference numbers. We will endeavour to upload any relevant planning files to our website within 2 weeks of the request.

If you are looking for Planning applications in the City of Bath between 1948 and 1996 an online catalogue is available here.

How do I check planning constraints?

* Find your address

* Ensure you have selected the ‘Maps’ tab on the top left of the screen

* Select the Planning map on the left
