Purpose To provide low-cost housing, the Myanmar Government is attempting to use public–private partnership (PPP) to attract private investors. However, there is little information concerning the influencing factors for implementing PPP low-cost housing projects in Myanmar. This paper, therefore, aims to identify and analyse these factors. Design/methodology/approach A total of 51 in-depth interviews were conducted with interviewees involved in various kinds of housing projects implemented through the adoption of PPP or other approaches. The methods of data collection and the analysis are based on grounded theory (GT) methodology. Findings Using the GT method to analyse the interviews, five categories emerged from 50 influencing factors regarding the establishment and implementation of the PPP model for low-cost housing in Myanmar: provision of incentives; obstacles in implementing PPP for all stakeholders; barriers to private sector participation; public sector responsibilities and challenges; and attraction factors and challenges for financial institutions. Among 12 newly found factors, the three most important for PPP low-cost housing in Myanmar are the availability of project funding, the resolution of land-acquisition issues and the development of a sound financing system. Research limitations/implications Our findings strengthen previous studies by identifying factors affecting PPP low-cost housing either specific to Myanmar or common among other countries. Of the 50 factors identified, 38 factors were found in previous studies, but 12 are likely specific to Myanmar. Practical implications Our findings can be used by governments, particularly the Myanmar Government, and financial agencies to understand the low attractiveness of PPP low-cost housing for investors and to develop/improve policies to stimulate PPP low-cost housing, especially in Myanmar. Originality/value Many previous studies have been undertaken to identify factors that influence the implementation of PPP for low-cost housing. However, to the best of the authors’ knowledge, there are no prior studies specific to Myanmar in this context.
