Assessment of Housing Conditions in Informal Settlements: A Case Study of Ajegunle, Lagos State

Informal settlements remain a persistent urban challenge in Nigerian cities, characterized by substandard housing, inadequate infrastructure, and social vulnerability. This study assesses housing conditions in Ajegunle, one of Lagos State's most densely populated informal communities, with a focus on structural quality, access to basic services, and residents' tenure security. Using a descriptive research design, data were collected through a systematic random sampling of 250 households, supplemented by key informant interviews with community leaders and Lagos State officials. Housing quality was evaluated using a structured scoring index covering roofing materials, wall construction, floor type, ventilation, and sanitation access. Findings are anticipated to indicate widespread deficiencies in sanitation infrastructure, overcrowding, and insecure land tenure, consistent with broader patterns documented in recent Nigerian urban studies. The study also examines the role of community-based organizations in informal upgrading efforts and their interaction with state-level housing policies. By mapping the spatial distribution of housing deprivation within Ajegunle, this research provides evidence for targeted intervention areas and prioritization frameworks. The study concludes with policy recommendations aimed at in-situ upgrading, regularization of land titles, and integration of slum improvement programs into the Lagos Metropolitan Development and Governance Project framework. This research contributes practical documentation to ongoing debates on housing rights and informal urbanization in Nigerian coastal cities.
