Where do I submit my planning applications?

  • If you live within the National Park boundary you should  submit your planning applications to Chichester District Council in the normal way. Please make planning fees cheques payable to South Downs National Park Authority.
  • If you submit your application through the Planning Portal, this will be routed to Chichester District Council who will deal with it on behalf of the SDNPA.

What happens next?

  • If the application is deemed 'significant' by the SDNPA then the application will be determined by a case officer at the SDNPA. See PDF document.
  • All other (that is, most) applications will be determined by Chichester District Council, working in partnership with the SDNPA. These applications will be decided by the Chichester District Council planning committee, or planning officer, in accordance with local provisions for officer delegation.
  • All communications regarding a planning application (letters, emails, phone calls) should be directed to Chichester District Council, not the SDNPA.
