   St Albans took a median of 76 days over the applications it decided in the last year.

This application is with St Albans for determination, against a statutory target of eight weeks. Over the last year St Albans decided householder applications in a median of 110 days. More in our guide to how long planning decisions take.

Householder applications cover work to an existing house and its garden, such as extensions, lofts and outbuildings, and cannot create a separate dwelling or change what the building is used for. More in our guide to planning application types.
