What are the key due diligence steps required before purchasing land for multi-unit residential development in Adelaide?

Before purchasing Adelaide land for multi-unit residential development, key due diligence steps include a thorough planning assessment via PlanSA's Planning and Design Code to confirm zone allowances, maximum building height, setbacks, and car parking requirements. Investigate existing infrastructure capacity, particularly stormwater, sewerage, and utilities, for potential upgrade costs. Conduct a detailed site analysis for contamination, soil stability, and bushfire risk. Engage a surveyor for boundary confirmation and a services engineer for preliminary advice. Financial viability modelling must incorporate all development contributions, consultant fees, and construction costs, ensuring a robust feasibility program.
