In this paper, we tried to analyze the characteristic of optimum long-term building repair plan. As a result, the suitable repair plan in each time point can be called 'Maximum-repair' that restores the performance to the first level or 'Non-repair' that does not repair at all . The decision depends on the balance of the repair cost and the expected income increase. The suitable repair plan has strong relation to the building degradation tendency and generally speaking, it has robustness against other factors.
