Public–private partnerships (PPPs) are being viewed as the next best alternative procurement option in the construction sector, particularly in developing countries such as Tanzania. This preliminary study aims to investigate the following aspects of PPP (PPPH) housing project delivery: (1) cost and affordability; (2) the influence of sustainability factors; and (3) the associated benefits which, despite the plethora of PPP-related studies, few have specifically examined. To achieve these objectives, a questionnaire survey was conducted with 28 stakeholders from Tanzania. Frequency analysis and one-sample t-tests were used to rank and identify the significant factors and outcomes of HPPP adoption. The most critical cost and affordability factors were that PPP procurement: (1) is economical compared to traditional methods; (2) offers value for money; and (3) can facilitate affordable housing supply outcomes. The major sustainability factors were beginning sustainability assessment from the feasibility stage and considering sustainability in project viability evaluation. Encouraging private sector innovation and management skills, risk sharing and value for money were found to be among HPPP delivery benefits. These findings provide insights for PPP policy and practitioners in understanding the significant factors in PPPH delivery.
