The failure of the 'Housing Diversity Code' to deliver housing diversity

This article explores the policy failure of the NSW 'Low Rise Housing Diversity Code' (implemented through State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (Codes SEPP)). The Code came into full effect (across all NSW LGAs) on the 1st of July 2020 following a number of deferral periods since its formal adoption in 2018. The Code was intended to address Sydney's 'missing middle', notably medium density housing to address affordability and the relative imbalance in available housing typologies between polarised market choices; the detached suburban house on a remote (greenfields) lot, and the apartment in a high density metropolitan centre. The policy ultimately failed to deliver the intended diversity it had seemingly promised. This article explores technical, legislative, political and economic factors contributing to the Code's limited application, as well as actions that further curtailed housing diversity, counter to the Code's intent.
