Yes, some Clarendon properties can support a granny flat, but eligibility depends heavily on the individual site. Many properties have larger lots, so land size may not be the main constraint; on eligible residential-zoned land, the NSW Housing SEPP allows a secondary dwelling to qualify for CDC from 450m², with a maximum floor area of 60m², subject to the required standards. In Clarendon, zoning, Hawkesbury-Nepean flood risk, evacuation constraints and available services can have a greater impact on the approval pathway, so these should be checked before any design work begins.
Get inspiration from our recent granny flat projects across Clarendon and surrounds — and see how we’ve turned different properties into practical new spaces.
Clarendon is a practical location for a granny flat because of its detached housing, family households and access to larger properties. In the 2021 Census, all 35 occupied private dwellings recorded in Clarendon were separate houses, 82.9% were family households, and the suburb averaged 3.6 people per household, although these figures reflect Clarendon’s small population. For suitable properties, a granny flat can provide independent accommodation for older parents or adult children, a future downsizing option, or additional rental income. With Clarendon Station and easy access to Richmond and Windsor, it can also suit households wanting extra living space while remaining connected to the wider Hawkesbury area.

A granny flat in Clarendon can be approved through a private certifier as complying development when the lot is 450m2 or larger, the secondary dwelling is no more than 60m2 (or 25% of the main house, whichever is less), and setbacks, height and landscaping meet Housing SEPP 2021 standards. This pathway typically takes 10 to 15 business days once documentation is complete. Blocks inside a flood planning area can still qualify, but floor levels and fill must meet the council's flood controls, which we check against the flood certificate before design. On rural or large lot zoned land in Clarendon the CDC route is usually not available, so a DA to council is the normal path.
Not meeting one complying development requirement does not rule a project out. Where a lot in Clarendon is zoned rural or large lot residential, is under 450m2, or is affected by a flood planning control, a development application can be lodged with Hawkesbury City Council. Assessment times are longer than a CDC, but the council does approve secondary dwellings through this route.
Clarendon is administered by Hawkesbury City Council and assessed under the Hawkesbury LEP 2012. The whole suburb falls within the one council area. Granny Flats X confirms the consent authority for your specific block during the initial property assessment.
