The repair time of buildings due to earthquakes is one of critical factors to determine the recovery time and the recovery point in the business continuity plan. The repair time of buildings which were damaged in 1995 Hyogoken Nanbu earthquake is investigated. In order to estimate the repair time of buildings, the statistical relations with respect to the repair time are examined by using the total floor area, the structural type, the building use and the seismic intensity. As a result, the regression curves which are considered into both the total floor area and the building use are proposed to calculate the repair time of buildings. The seismic repair time curve is evaluated through the uncertainty of these regression curves as well as the variance of the seismic fragility curves. The probable maximum repair time of buildings can be obtained in the same definition of probable maximum loss (PML).
