Do I need planning permission for a house extension?
We have a self-assessment form that will be available to help you decide if your proposal needs planning permission. Completing this form should help you understand whether you need planning permission for your extension. Should you wish to have further advice the Council can check your completed form and supporting information and provide an informal written opinion as to whether planning permission is required. The fee for this service can be found here.
Alternatively you can apply for a Certificate of Lawfulness. This is a legal document. There are two different forms depending on whether you have done the work or would like to. If you have not already done the work, choose the Certificate of Lawfulness (Proposed) forms. If you have already done the work you need Certificate of Lawfulness (Existing) forms. Having such a Certificate can be particularly useful if you wish to sell your house in the future, as it provides written legal evidence that work you have carried out did not require planning permission.
Application forms and fees can be found on the Planning Portal website. You can also download forms from the Planning Portal website. Further guidance on making an application and information needed to register an application can be found here.
Further guidance is available on our web site.
Please note the leaflet titled 'Lawful Development Certificate Do I Need One?' contains out of date fees and contact details. A link to fees can be found in the paragraph above.
The Councils address is :
Hastings Borough Council
Muriel Matters House
If planning permission is required there is some useful guidance here which explains the sort of things the Council would look at in assessing applications for extensions. Please note that the leaflet refers to old local plan policies however the principles remain the same. Up to date planning policy can be found here.
