The social sustainability transition in the construction sector seeks to improve safety and health of workers, gainful employment and total inclusiveness. However, it is novel in the Nigerian construction industry and a less debated domain within this framework is how employment requirements provide opportunities for the socially disadvantaged such as the poorly educated, youths, immigrants and disabled individuals to be employed in the construction industry. In Nigeria alone, there are over 27 million disabled human species, most of who are living in extreme poverty with poor quality of life. Furthermore, there are evidence of development projects designed and built in developing countries that have failed socially and many mass housing scheme in Nigeria suffices as examples. Drawing on a systematic review of relevant literature, this research qualitatively examines social sustainability practices in the Nigerian construction industry, and highlight strategies for diffusing the approach at each phase of the project life cycle. The outcome of the result will initiate a novel research domain and promote sound academic debate towards improving total inclusiveness in Nigerian and Africa’s built environment. The potential impact of this research is that it will contribute to the knowledge base of the social sustainability concept and provide an alternative solution to the increasing shortage of skilled labour force in the construction industry. Its conclusion surmises that social procurement is a strategic tool for creating employment for the disadvantaged in the construction sector.

The study focused on the connection between the standard of housing and household income in Nigeria's Ado-Ekiti. The population of Ado-Ekiti is expanding and includes a wide range of socioeconomic categories. The study adopted a primary method of data collection, respondents who are landlords or the oldest tenants were selected randomly to give answers to 1500 structural questionnaires distributed in the study area, and a total of 1311 responses were obtained. The study was categorized into three zones: Urban Core, Transitional and Peri-phery. The variables and data were captured with statistical tables. The study found out that 62% of respondents in the Urban Core earn less than the minimum wage as against 9.05 in the Peri-phery. Also, in the Core Area, 37.3%, 40.0%, 34.6%, 32.2%, 32.9% and 47.5% of roof, windows, doors, walls, floors and ceilings respectively were bad. The hypothesis formulated is that there is no significant relationship between housing quality and income level. Using Pearson Product Correlation shows that r-value (0.530) is higher than the r-tabulated r-value (0.195), this indicates that there is a strong correlation between the quality of housing and residents' income levels. The study concluded that income level and fund availability will always affect the realization of good quality housing, the study recommended that strong government intervention in housing the urban poor must be improved; development agencies and private developers should go into funding building maintenance most especially at the urban core.
