Kisumu: The National Construction Authority (NCA) has shut down two non-compliant construction sites in Seme Sub-County, Kisumu, as part of an ongoing quality assurance crackdown. The move follows growing concern over unsafe building practices and aims to ensure that all construction projects adhere to required safety standards and regulatory guidelines. The closure orders were issued yesterday after inspections revealed that the sites lacked basic approvals, documentation, and professional oversight. According to Kenya News Agency, the exercise comes amid heightened national scrutiny in the construction sector after a multistory building collapsed in Nairobi's South C area, triggering renewed enforcement across the country. Speaking during the operation, NCA Central Nyanza Regional Coordinator Architect Festus Mariera said the authority, working in collaboration with the Kisumu County Government, had inspected several ongoing projects in the area, with most found to be in breach of the law. 'We sampled a n umber of sites in Seme Sub-County and we had a challenging day because most of the projects were not compliant. Two of them have been issued with stoppage orders,' Mariera said. He highlighted common violations, including failure to obtain statutory approvals, absence of registered contractors, and lack of qualified professionals supervising the works. Mariera emphasized that construction should be led by a registered professional, typically an architect for building works or an engineer for civil projects, to guide the developer through approvals, documentation, and engagement of licensed contractors. He warned that contractors undertaking projects without valid NCA practice licenses were operating illegally, noting that some recent building collapses in the country involved contractors whose licenses had expired years earlier. 'If a contractor's practice license is not current, then legally they are not a contractor. Undertaking works under such circumstances is a violation of the law,' he warned. The NCA official added that contractors found working on undocumented or unregistered projects risk deregistration and prosecution under the National Construction Authority Act and the NCA Regulations of 2014, which are currently under review to tighten enforcement. Mariera also cautioned developers who engage unregistered contractors, stating they too face arrest and prosecution. 'Construction can only be undertaken by registered contractors or, for projects valued below Sh5million, by NCA-accredited site supervisors. Anything outside that is illegal,' he said. He further explained that the crackdown would continue, with more sites expected to be closed down to enhance compliance with building regulations. The authority can halt construction on several grounds, including lack of a site signboard, absence of perimeter fencing, failure to observe occupational safety and health requirements, use of unaccredited workers, engagement of unregistered contractors, and lack of an NCA compliance certificate. 'A site may ev en have a compliance certificate and still be stopped if we find safety breaches on the ground, such as failure to use protective gear or install safety netting,' he said. 'All construction projects, whether residential or commercial, must be registered with the NCA. Compliance is not optional, and the law will eventually catch up with offenders,' he added.
