How long does a DA take in Mosman?

Half of determined applications in Mosman were decided within 92 days of lodgement, with a mean of 105 days across 1,655 determined applications. The mean sits above the median because a small number of long-running applications pull it up.

The NSW median across councils with comparable volume is 46 days, so Mosman determines applications slower than the state's middle. Determination time varies widely by development type and by how complete the lodgement is.

What is in the record

Devlens links the four NSW registers into one timeline per site: development applications (DA), complying development certificates (CDC), construction certificates (CC) and occupation certificates (OC). That means you can see not just what was approved in Mosman, but what was actually built and when it was occupied.

Each record carries the address, applicant-declared cost of works, dwelling count, status, lodgement and determination dates, and a map position. The register is refreshed from the NSW Planning Portal every night.
