Infrastructure South Australia (ISA) commissioned the Australian Housing and Urban Research Institute (AHURI) to analyse the impacts of providing equitable access to secure, affordable, and appropriate housing at a population-wide scale. The objective of the project is to develop an effective impact assessment framework based on evidence of the benefits to inform housing policy and investment decisions.

This Final Report presents findings of an evidence review which synthesises the economic, social, and environmental impacts of housing identified through a global scan of literature. The findings from the global scan were categorised in an Impacts Map. This informed the development of a proposed impact assessment framework which captures a range of benefits that have potential to be selectively applied when conducting a cost-benefit analysis (CBA) of a diversity of housing interventions. These monetised, quantified, and qualitative benefits are designed to be utilised in project evaluation processes. This requires an assessment of the proposed project intervention and applying the relevant parameter values. The framework provides guidance on whether the parameter values are to be applied as an individual instance or an annual basis.
