Rapid urbanization in the Kathmandu Valley, Nepal, has increased the demand for housing, prompting the development of high-rise apartments to address space constraints and population density. This study investigates the factors influencing residents' satisfaction with infrastructure and service management in these apartments. Employing a cross-sectional quantitative design, data were collected from 287 residents across 10 high-rise apartments through structured questionnaires. Principal Component Analysis (PCA) was utilized to identify and categorize key factors affecting satisfaction, supported by reliability and validity tests, including the Kaiser-Meyer-Olkin (KMO) and Bartlett’s Test of Sphericity. Results indicate six latent variables explaining 78.803% of the total variance in satisfaction, highlighting components such as structural stability, water and sanitation systems, fire safety measures, and vertical circulation systems (e.g., lifts and staircases). Satisfaction levels were influenced by the quality of materials, apartment size, and adherence to safety regulations. Demographic data, including age, gender, and education, further shaped residents' perceptions. This research underscores the importance of addressing performance gaps in infrastructure and management services to enhance resident satisfaction and guide future high-rise developments in the region. The findings provide actionable insights for policymakers, developers, and urban planners aiming to improve housing conditions and ensure sustainable urban development in Kathmandu Valley.
