Abstract
Municipal infrastructure assets in Ethiopia face significant risks due to inadequate maintenance and management practices. A multilevel regression model will be applied to assess the impact of various factors on infrastructure asset performance at both local government (level 1) and national policy level (level 2). The multilevel regression analysis revealed that investment in maintenance and regular inspections significantly reduced the risk of failure by 30%. This study highlights the importance of integrating local governance with national policies for effective municipal infrastructure asset management. Local governments should prioritise investment in routine maintenance and inspection programmes, while national authorities must provide consistent funding and regulatory oversight.
