AreaSearch analysis of residential development drivers sees Dundas Valley recording a relatively average level of approval activity when compared to local markets analysed countrywide

AreaSearch analysis of ABS building approval numbers in Dundas Valley shows approximately 43 dwelling approvals per year over the past five financial years, totalling about 217 homes. As of FY-26, 84 approvals have been recorded. The average population increase per dwelling built between FY-21 and FY-25 was around 0.1 people per year. New construction is keeping pace with or exceeding demand, offering more housing options and potentially driving population growth beyond current expectations.

The average expected construction cost value of new properties is $639,000, indicating developers are targeting the premium market segment. In FY-26, $2.1 million in commercial development approvals have been recorded, suggesting minimal commercial development activity. Compared to Greater Sydney, Dundas Valley records about three-quarters of the building activity per person and ranks among the 68th percentile nationally. New building activity comprises approximately 25.0% detached houses and 75.0% medium and high-density housing, marking a shift from the area's existing housing composition (currently 65.0% houses). This trend may reflect decreasing availability of developable sites and changing lifestyles.

Dundas Valley has around 199 people per dwelling approval, indicating characteristics of a growth area. According to AreaSearch's latest quarterly estimate, the area is projected to gain approximately 1,175 residents by 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting population growth beyond current projections.
