Legal Aspects of Urban Planning Enforcement in Nigerian Cities: Case Study of Kaduna Metropolitan Area

Rapid urbanisation in Nigerian cities has generated acute challenges for planning authorities in enforcing physical development regulations, managing illegal construction, and maintaining functional urban infrastructure. Kaduna Metropolitan Area, in North West Nigeria, has experienced significant unplanned urban sprawl, with widespread construction without planning permits, non-compliance with building setback requirements, and encroachment on public rights of way. This study examines the legal framework and enforcement practice governing urban planning in Kaduna Metropolitan Area, focusing on the Kaduna State Urban and Regional Planning Development Authority Law and its implementation. A professional practitioner research design was employed, incorporating interviews with KASUPDA enforcement officers, town planning lawyers, and property developers, alongside field observations of enforcement actions in selected wards. Secondary data was sourced from KASUPDA administrative records, World Bank Nigeria urban development reports, and academic urban governance literature from 2019 to 2024. Findings reveal that enforcement actions are inconsistently applied and frequently influenced by informal payments, undermining the authority of the regulatory framework. Statutory provisions for demolition and stop-work orders are rarely enforced against politically connected developments. Recommendations include establishing an independent planning enforcement oversight board, mandatory electronic permit tracking systems, and community-based planning watch committees. This research provides professional guidance for urban planning law and governance practitioners in North West Nigeria. Keywords: urban planning, enforcement, Kaduna, KASUPDA, building regulation.
