   Awaiting decision

   Decision expected by 2 October 2002, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

   North Hertfordshire took a median of 49 days over the applications it decided in the last year.

This application is with North Hertfordshire for determination, against a statutory target of eight weeks. Over the last year North Hertfordshire decided lawful development applications in a median of 36 days. More in our guide to how long planning decisions take.

A lawful development certificate is a legal determination that existing or proposed works do not need planning permission; the merits of the scheme are not considered. More in our guide to planning application types.
