Questions

How many development applications are there in Double Bay?

113 development applications (DAs) and complying development certificates (CDCs) were lodged in Double Bay in the last 12 months: 83 DAs and 30 CDCs. 23 lodged in the last two years are still being assessed.

How do I check DAs near a property in Double Bay?

Enter the address in WIBI. The report lists every DA and CDC within 250 metres, closest first, plus big projects up to 800 metres away, with what each one means for you. You can also search the NSW Planning Portal or Woollahra Municipal Council's DA tracker.

What's the difference between a DA and a CDC?

A development application (DA) is assessed by council, and neighbours are usually notified and can comment. A complying development certificate (CDC) is a fast-track approval for work that meets set standards; it can be issued by a private certifier and neighbours can't object, though they're told before work starts.
