Yes, many Bligh Park properties can accommodate a granny flat, particularly the suburb’s established homes on blocks commonly around 500–700m². Under the NSW Housing SEPP, a secondary dwelling may qualify for CDC on lots of at least 450m², with a maximum floor area of 60m², provided the required development standards are met. Bligh Park is within Hawkesbury City Council and includes substantial R2 Low Density Residential land, but each property should still be checked for setbacks, available backyard space and flood-related constraints, as parts of the suburb can be affected by Hawkesbury-Nepean flood planning controls.
Get inspiration from our recent granny flat projects across Bligh Park and surrounds — and see how we’ve turned different properties into practical new spaces.
Bligh Park is a strong location for a granny flat because of its established family housing, generous residential blocks and active rental market. Around 80% of occupied homes are separate houses and 78.3% are family households, making additional accommodation useful for older parents, adult children or extended family. With median house rents currently around $655 per week and rental demand increasing, homeowners with suitable backyard space can also use a granny flat to create an additional rental income stream while keeping their existing home.

A granny flat in Bligh 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. 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 Bligh Park is under 450m2, sits in a heritage conservation area, 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.
Bligh Park 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.
