Development monitoring in The Hills Shire — common questions
How active is development in The Hills Shire?
The Hills Shire has moderate-to-high DA volumes driven by secondary dwelling CDCs in established suburbs and large subdivision DAs in growth precincts around Box Hill and Rouse Hill. Castle Hill and Kellyville see consistent residential construction activity. Sydney Metro Northwest infrastructure DAs have also added to recent volumes.
What types of development should Hills Shire homeowners watch?
Secondary dwelling CDCs — very common given the large lot sizes that qualify under SEPP Housing 2021. Multi-dwelling housing DAs near town centres. Subdivision DAs in greenfield precincts that can create new access roads and infrastructure near existing properties.
Can I object to a neighbour's DA in The Hills Shire?
Yes. The Hills Shire Council publicly notifies DAs for the standard 14-day period. Weekly alerts give you time to prepare a submission before the deadline. CDCs through private certifiers are not notified — the weekly check covers these.
How far away do alerts cover?
Alerts cover applications within 200m. In The Hills' lower-density suburban areas this typically covers 30–60 properties on larger blocks.
Are large-scale subdivision DAs common in The Hills?
Yes in the growth precincts (Box Hill, Rouse Hill, Kellyville Ridge). If you're near the urban growth boundary, subdivision and infrastructure DAs are worth monitoring as they can affect access roads, drainage, and amenity over time.
