Information and guidance for changes to buildings.
You're likely to need planning permission for new buildings and for major changes to existing properties and the local environment.
Minor work on listed buildings (inside or outside) or work in conservation areas is also likely to need consent.
In certain circumstances, developments are automatically permitted – this 'permitted development’ does not require an application.
Check the Permission Needed? section of the Planning Portal, and look up your project in their list of common projects to see if permitted development applies in your case.
Please be aware that for formal confirmation that works are permitted development or are not development at all in planning terms, you will need to apply for a certificate of lawful development (LDC).
Even if your development seems to be permitted by these rules, it's still important to check that the building or land has not had its permitted development rights removed or limited for some reason. In some cases, there will be special conditions attached to previous development that can restrict these rights.
Brighton & Hove also has Article 4 Directions which limit the scope of permitted development rights in these areas of the city.
To find out if your property is protected as a listed building or falls within a conservation area please check our listed buildings and conservation areas pages.
See also our policies and guidance on listed buildings and demolition in conservation areas.
If your property is affected, you will need to apply for listed building consent in addition to your application for planning permission.
If you need to prove to anyone, such as a prospective buyer, that building work you’ve done is lawful, you can apply for a Certificate of Lawful Development (LDC).
Find what you need to do by using Brighton & Hove's LDC Checklist.
See our policy advice and guidance section of our website for more information.
Please contact our Arboricultural Service for any advice on work relating to trees, or if you see tree work taking place which you believe may not be authorised.
Even if your building project does not need planning permission, you will still need to comply with building regulations.
