Yes, many Shalvey properties may be suitable for a granny flat, particularly established homes on larger residential blocks. Under the NSW Housing SEPP, a detached secondary dwelling can use the Complying Development Certificate (CDC) pathway on lots of at least 450m², provided all relevant site and design standards are met. Shalvey is within Blacktown City Council and includes R2 Low Density Residential land, where secondary dwellings are permitted under the Housing SEPP. Local property records show examples of established Shalvey blocks from about 555m² to 666m², although lot sizes vary and every address should be assessed individually. A secondary dwelling is generally limited to 60m² of floor area, subject to the applicable planning controls. Before choosing a design, also check the property’s flood, drainage and bushfire constraints, particularly where local catchment conditions may affect the site.

Shalvey offers a strong case for a granny flat because it combines established family housing with substantial rental demand. At the 2021 Census, 77.4% of Shalvey households were family households, while 51.1% of occupied homes were rented, well above the NSW rental rate of 32.6%. The suburb is also dominated by separate houses, which make up 92.1% of occupied dwellings, giving suitable properties greater potential to use existing backyard space. Shalvey also forms part of the wider Mount Druitt precinct, where planning is focused on improving access to employment, healthcare, education and local services, including Mount Druitt Hospital and TAFE. For homeowners planning ahead, a granny flat can provide private accommodation for ageing parents or adult children, while retaining the flexibility for rental income or downsizing later.

A granny flat in Shalvey 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.
Not meeting one complying development requirement does not rule a project out. Where a block in Shalvey is under 450m2, sits in a heritage conservation area, or is affected by a flood planning control, a development application can be lodged with Blacktown City Council. Assessment times are longer than a CDC, but the council does approve secondary dwellings through this route.
Shalvey is administered by Blacktown City Council and assessed under the Blacktown LEP 2015. 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.
