Evaluation of Accessibility in Commercial Buildings for Persons with Disabilities in Lagos Island

The right of persons with disabilities to access public and commercial built environments is enshrined in Nigerian disability legislation and international conventions, yet enforcement and compliance in Lagos commercial districts remain poorly documented. This study evaluates the accessibility provisions of commercial buildings along selected streets in Lagos Island, assessing compliance with the Nigerian Universal Design Code and COREN accessibility guidelines. Physical audits were conducted on fifty commercial buildings using a structured accessibility checklist covering entrance ramp provision, door width, corridor clear width, lift provision, accessible toilet facilities, tactile ground surface indicators, and signage legibility. Interviews were conducted with twenty persons with physical or visual disabilities who regularly navigate the district. Findings reveal that only twelve percent of assessed buildings provided full ramp access to their main entrances. Accessible toilet facilities were entirely absent in seventy-eight percent of buildings. Door widths fell below the 900 mm minimum in forty-four percent of main entrances. None of the fifty buildings provided any form of tactile or audible navigation guidance. Persons with disabilities interviewed reported systematic exclusion from commercial activities, heavy reliance on informal assistance from bystanders, and significant safety risks from traffic on unprovided pedestrian routes. The study concludes that accessibility non-compliance in Lagos Island commercial buildings is pervasive and unremedied, and recommends mandatory accessibility audits as a condition of building renewal permits, with the Lagos State Building Control Agency tasked as the enforcement authority.
