The level of residential development activity in Marrickville - South is very low in comparison to the average area assessed nationally by AreaSearch

Marrickville - South averaged approximately 30 new dwelling approvals annually over the past five financial years ending June 2021, totalling 151 homes. As of June 2026, two approvals have been recorded. During this period, population has decreased slightly, yet housing supply has remained adequate relative to demand, indicating a balanced market with good buyer choice. The average construction cost value for new properties is $431,000, which is slightly above the regional average, suggesting focus on quality developments.

This financial year, there have been $680,000 in commercial approvals, reflecting the area's residential nature. When compared to Greater Sydney, Marrickville - South has roughly half the rate of new dwelling approvals per person and ranks among the 12th percentile nationally for areas assessed, resulting in relatively constrained buyer choice. This is lower than the national average, indicating market maturity and possible development constraints. New developments consist of 22.0% detached dwellings and 78.0% townhouses or apartments, promoting denser development that appeals to downsizers, investors, and entry-level buyers. As of June 2021, Marrickville - South had approximately 1239 people per approval, signifying a mature, established area.

According to the latest AreaSearch quarterly estimate, the area is projected to add 1,386 residents by 2041. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth in the future.
