Do I need planning permission?

Pre-application advice

During the Covid period we were forced to suspend the pre-application advice service and this has not resumed due to a significant increase in workload. However, the service has now resumed and we would encourage all potential applicants to engage in pre-application discussions.

All enquiries should be sent in writing to the development management section using the full contact details (at the end of the page), providing as much information as possible (we can only answer enquires that include the full postal address of the property or a location map showing the site and a sketch proposal). We will not deal with your enquiry until the correct fee is paid.

Do I need planning permission?

If you wish to build on land, or make alterations to an existing building or structure, you may need planning permission and/or an application under the current building regulations. For details about your obligations under the current building regulations please see our Building Control section.

The information below will help you to decide whether planning permission is required, as well as to search for other applications, relating either to your own, or to any other property within the district.

If you wish to build or alter a structure within the South Downs National Park area of Adur or Worthing, you will need to apply for permission through the South Downs National Park Authority planning service:

If you do not know if you need planning permission, please see the Planning Portal's guidance and interactive house, interactive terrace and mini guides to help you determine whether the work you want to carry out requires planning permission.

If you need permission:

If you have found that you do need planning permission then please see submit a planning application.

You may also require building consent.

Permitted development

You can make certain types of minor changes to your house without needing to apply for planning permission. These are called 'permitted development rights'. They derive from a general planning permission granted not by the local authority but by parliament. Bear in mind that the permitted development rights which apply to many common projects for houses do not apply to flats, maisonettes or other buildings.

Some works are deemed 'permitted development'; and can be carried out without making a formal planning application, however, detailed planning advice is available on the Planning Portal. In addition, you should always check the planning history of your property in case any conditions, imposed as a result of previous applications, have removed your 'permitted development' rights. You should also check to see whether your property is a listed building, in a conservation area, or within an area where there is an 'Article 4 Direction' which can all remove 'permitted development' rights. Please see the link below to the Planning Portal:

If you would like formal confirmation from Adur & Worthing Councils that planning permission is not required you should make an application for a 'certificate of lawfulness for a proposed use or development'. This type of application simply asks "is planning permission is required". If it is not required you will be issued with a certificate confirming this. If planning permission is required, you will then need to continue on to a formal planning application. See:

Neighbour consultation scheme

The neighbour consultation scheme relates to larger single-storey rear extensions.

Extensions of over four and up to eight metres for detached houses and over three and up to six metres for all other houses, must go through this process.

If you wish to build a large extension you must notify the planning department, who will then consult the adjoining neighbours to advise them of your planned development.

If your neighbours raise any concerns or objections, the planning department will decide if their objections reveal any impact on the amenity of the neighbouring properties and whether your plans can go ahead.

From 19th August 2019, government introduced a fee for this process. To find out how much a planning application costs use the fee calculator on the Planning Portal:
