Recent residential development output has been above average within Klemzig when compared nationally

Based on AreaSearch analysis of ABS building approval numbers allocated from statistical area data, Klemzig has seen around 39 new homes approved each year. Over the past five financial years, between FY-21 and FY-25, approximately 197 homes were approved, with an additional 25 so far in FY-26. On average, about 2.2 people have moved to the area per new home constructed over these five years, indicating healthy demand which supports property values.

New homes are being built at an average expected construction cost value of $379,000, suggesting developers target the premium market segment with higher-end properties. This financial year has seen $7.3 million in commercial approvals registered, reflecting Klemzig's primarily residential nature. Compared to Greater Adelaide, Klemzig has around two-thirds the rate of new dwelling approvals per person and ranks among the 69th percentile nationally when assessed areas are considered.

Recent construction comprises 90.0% detached dwellings and 10.0% townhouses or apartments, preserving the area's suburban nature with an emphasis on detached housing attracting space-seeking buyers. Interestingly, developers are building more traditional houses than the current mix suggests (68.0% at Census), indicating continued strong demand for family homes despite density pressures. The location has approximately 192 people per dwelling approval, suggesting an expanding market. Population forecasts indicate Klemzig will gain 521 residents through to 2041, based on the latest AreaSearch quarterly estimate. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
