Neighbour Development Alerts in Inner West, NSW

How active is development in the Inner West?

The Inner West has consistently high DA and CDC volumes. Medium-density uplift under the Inner West LEP, dual-occupancy approvals, and apartment conversions generate significant ongoing activity. Suburbs like Marrickville, Leichhardt, and Ashfield regularly see 20–40 new applications per month within 500m of residential addresses.

What types of development should Inner West homeowners watch?

The most common DAs affecting neighbouring properties are: dual-occupancy and secondary dwelling approvals (can change street character), demolition and new construction of multi-dwelling housing, and commercial development on mixed-use corridors. Building works within 50m can also affect street parking and construction amenity.

Can I object to a neighbour's DA in the Inner West?

Yes. DAs in Inner West are publicly notified for at least 14 days. You can submit an objection to Inner West Council during the notification period. Weekly alerts give you enough lead time — you typically have 14–28 days from lodgement to submit a submission.

How far away do alerts cover?

The tool checks for DA and CDC applications lodged within 200m of your address. In a dense suburb like Newtown or Leichhardt, this can include 40–80 properties. Most neighbours who would affect your amenity, solar access, or street parking fall within this radius.

Do alerts include both council DAs and private certifier CDCs?

Yes. The tool draws from the NSW ePlanning Portal which includes both council development applications (DAs) and complying development certificates (CDCs) lodged through private certifiers. CDCs — which don't require council approval — are often the fastest route for neighbours adding granny flats or making additions.
