This study examined the inadequacies of housing availability and delivery associated with traditional land ownership system in different states across the Niger Delta of region, Nigeria. The cross-sectional research design was adopted in the study. The data for this study was elicited from 400 household heads in the study area determined through the use of Taro Yamane’s and Kumar stratum allocation formulas whereas the Kruskal–Wallis test was employed for analysis. Housing availability was found to be inadequate with only 36% affirming that housing units are sufficient, while 52.7% disagreed (WM = 2.99). Accessibility also scored low (WM = 2.90), and population growth was consistently seen as a constraint, with 79% agreeing it reduces availability (WM = 4.16). Infrastructure deficits were critical, with 80.5% strongly agreeing that lack of basic services limits housing expansion (WM = 4.19). Effectiveness of housing development recorded weak results, with most weighted means below 3.0, including project timeliness (WM = 2.90), affordability (WM = 2.86), infrastructure provision (WM = 2.86), and policy support (WM = 2.86). The result revealed no statistically significant differences (at p > .05), indicating uniformity of perceptions across respondents. It is concluded from the findings that land ownership system is a major constraint affecting housing development and delivery. Consequently, holistic policy reforms that enhance affordability, and strengthen infrastructure provision were strongly recommended.
