Residential development activity is slightly higher than average within Cheltenham when compared nationally

AreaSearch analysis of ABS building approval numbers in Cheltenham shows approximately 20 new homes approved annually. From financial years FY-21 to FY-25, around 100 homes were approved, with an additional 24 approved so far in FY-26. This results in an average of about 1.5 new residents per year per dwelling constructed over the past five financial years.

The supply and demand balance appears stable, with new dwellings developed at an average expected construction cost value of $320,000. In terms of commercial development, $6.1 million in approvals have been registered this financial year, indicating limited focus on commercial projects compared to residential ones. When comparing Cheltenham's construction rates per person to Greater Adelaide, the area maintains similar market equilibrium consistent with surrounding areas. The current building activity shows 33.0% detached dwellings and 67.0% medium and high-density housing. This shift from the existing housing stock (currently 81.0% houses) indicates decreasing availability of developable sites and reflects changing lifestyles and demand for more diverse, affordable housing options.

The location has approximately 102 people per dwelling approval, indicating a low density market. According to AreaSearch's latest quarterly estimate, Cheltenham is projected to add 409 residents by 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
