Yes, many Glenmore Park properties can accommodate a granny flat, but eligibility varies between the suburb’s older and newer stages. Under the NSW Housing SEPP, a secondary dwelling may qualify for Complying Development on lots of at least 450m², provided all other planning standards are met, with the granny flat generally limited to 60m². Older parts of Glenmore Park often have larger residential blocks, while newer stages include smaller lots that may fall below the 450m² CDC threshold. Properties near Mulgoa Nature Reserve and environmental corridors should also be checked for bushfire-prone land and asset protection requirements before a design is selected.

Glenmore Park is strongly family-oriented, making extra independent living space particularly valuable. Around 87% of local households are family households, creating a practical case for accommodation for adult children, ageing parents or extended family without requiring them to move away from the area. The suburb is also well placed for Penrith and Nepean Hospital, where a more than $1 billion redevelopment is expanding health services and supporting local employment. Rental demand provides another option for homeowners, with Glenmore Park’s broader rental market currently sitting around $730 per week, although individual granny flat rents will vary. For homeowners with suitable backyard space, a granny flat can turn underused land into a flexible home for family today and a potential income-producing asset later.

A granny flat in Glenmore Park 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. Bushfire prone land does not rule out a CDC, but the design must meet the mapped Bushfire Attack Level, so the RFS map is the first thing we check.
Not meeting one complying development requirement does not rule a project out. Where a block in Glenmore Park is under 450m2, sits in a heritage conservation area, or is affected by bushfire prone land mapping, a development application can be lodged with Penrith City Council. Assessment times are longer than a CDC, but the council does approve secondary dwellings through this route.
Glenmore Park is administered by Penrith City Council and assessed under the Penrith LEP 2010. 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.
