Survey of Housing Conditions in Informal Settlements of Port Harcourt, Rivers State

This study surveys housing conditions in selected informal settlements in Port Harcourt, Rivers State, South South Nigeria, providing a systematic assessment of physical housing quality, basic service availability, and occupant characteristics in an environment that has received limited systematic attention from estate management researchers. Port Harcourt's waterfront communities and peri-urban informal settlements house a significant proportion of the city's population but are subject to periodic demolition threats and receive minimal planned infrastructure investment. The study employs physical housing condition surveys and structured household interviews across four settlements: Okrika, Diobu, Rumuobiakani, and Waterfront, covering 200 residential units selected through systematic random sampling. Assessment parameters include structural integrity, ventilation, sanitation provision, water access, occupancy density, and tenure security. Findings reveal that over 60 percent of surveyed dwellings use wood or mud brick construction with poor weatherproofing. Access to piped water is negligible, with shared boreholes or vendor purchases as primary water sources. Latrine-to-household ratios are severely overcrowded, averaging one facility per eight households. Overcrowding is widespread, with average occupancy of 3.8 persons per bedroom. Tenure insecurity is a dominant concern, particularly in waterfront communities subject to government clearance notices. The study recommends developing an in-situ upgrading policy for identified informal settlements rather than demolition, incorporating co-design of improvements with existing residents.
