AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections for areas not covered by ABS data, released in 2022 with a base year of 2021.

AreaSearch analysis of residential development drivers sees Mount Kuring-Gai recording a relatively average level of approval activity when compared to local markets analysed countrywide

AreaSearch analysis of ABS building approval numbers shows Mount Kuring-Gai experienced around 5 dwelling approvals annually over the past 5 financial years, totalling an estimated 27 homes from FY-21 to FY-25. As of FY-26, 1 approval has been recorded. On average, 7 people moved to the area per year for each dwelling built during this period.

This demand exceeds new supply, typically leading to price growth and increased buyer competition. New properties are constructed at an average expected cost of $428,000, below regional norms, offering more affordable housing options. Compared to Greater Sydney, Mount Kuring-Gai shows moderately higher new home approvals, with 10.0% above the regional average per person over the past 5 years. This preserves reasonable buyer options while sustaining existing property demand. However, this activity is under the national average, indicating the area's established nature and suggesting potential planning limitations. Recent construction comprises 50.0% standalone homes and 50.0% townhouses or apartments, a notable shift from the area's existing housing composition of 95.0% houses.

This skew toward compact living offers affordable entry pathways, attracting downsizers, investors, and first-time purchasers. The estimated count of 411 people in the area per dwelling approval reflects its quiet, low activity development environment. Population forecasts indicate Mount Kuring-Gai will gain 241 residents through to 2041, according to AreaSearch's latest quarterly estimate. Construction is maintaining a reasonable pace with projected growth, although buyers could encounter growing competition as population increases.
