Recent residential development output has been above average within Serpentine - Jarrahdale when compared nationally

Serpentine-Jarrahdale averaged approximately 27 new dwelling approvals per year. Over the past five financial years, from FY21 to FY25, a total of 135 homes were approved. In FY26 up until now, there have been 15 approvals.

Each year, around 3.5 new residents arrive per dwelling constructed on average during these five financial years. This high demand relative to supply typically drives price growth and increased buyer competition. New properties are constructed at an average expected cost of $283,000.

Compared to Greater Perth, Serpentine-Jarrahdale has significantly less development activity, approximately 59.0% below the regional average per person. This scarcity of new homes usually strengthens demand and prices for existing properties. Recent building activity consists solely of standalone homes, preserving the area's traditional low-density character with a focus on family homes catering to those seeking space. Currently, there are around 302 people per approval in Serpentine-Jarrahdale, indicating a transitioning market. Population forecasts predict an increase of 367 residents by 2041. Based on current development patterns, new housing supply should meet demand adequately, providing favourable conditions for buyers and potentially facilitating population growth beyond current projections.
