This paper describes a case-study of serviceability performance of a base-isolated building on a basis of long-term seismic monitoring data. Investigation on the seismic response emphasizes on the influence of building asymmetricity on the characteristics of seismic response and the long-term building response characteristics for over three years between 2010 and 2012 under various amplitudes of earthquakes. The building is an asymmetric base-isolated L-shaped structure consisting of seven-story and fourteen-story building with vertical void. Vibration monitoring system was installed on the building and seismic responses were recorded including the strongest shaking (PGA 0.80–1.40m/s²) experienced during the March 11, 2011 Great East-Japan Earthquake
