Over the past five financial years, from FY-21 to FY-25, a total of 118 homes received approval, with an additional 11 approved in FY-26 so far. On average, about 1.7 people moved to the area each year for every dwelling built during these five years.

This balance between supply and demand has contributed to stable market conditions. The average expected construction cost value of new dwellings is $190,000, which is lower than regional levels, suggesting more affordable housing options for buyers.

Compared to the rest of South Australia (SA), Mallala has shown slightly higher development levels, with 14.0% above the regional average per person over the five-year period from FY-21 to FY-25. This has helped maintain good buyer choice while supporting existing property values. Recent building activity consists solely of standalone homes, preserving the area's traditional low-density character and catering to families seeking space. As of now, Mallala has about 189 people per dwelling approval, indicating an expanding market. According to AreaSearch's latest quarterly estimate, Mallala is projected to grow by 615 residents by 2041.
