By reducing bureaucratic hurdles, permitting times, and design costs, PHDC aims to address housing shortages and streamline development. In recent years, jurisdictions in the United States, Canada, and Australia have implemented or piloted PHDC programs. However, despite increasing adoption, scholarly analysis remains limited, with much of the discourse confined to grey literature and anecdotal evidence. This study bridges the knowledge gap through a literature review and analysis of 16 case studies, examining PHDC’s historical origins, contemporary applications, and key challenges. It critically evaluates perceived benefits, such as cost savings and expedited permitting, </a><a href="" target="_blank">against real-world limitations</a>, including low engagement rates, limited design flexibility, and uncertain long-term affordability impacts. Findings indicate that while PHDC offers administrative efficiencies, it has not demonstrated transformational potential in solving housing affordability challenges. Regulatory frictions, market competitiveness, and the lack of financial incentives remain barriers to adoption. This study cautions against overreliance on PHDC and concludes with research and policy recommendations, emphasising broader housing strategies, improved permitting processes, and alignment with market needs to enhance PHDC’s effectiveness.</p>
