The problem of rebuilding superannuated condominiums has become a serious issue not only for large cities but for local cities as well. Local cities face many issues such as decline of a central district and financial slip. In a sense, solution to these problems would be more difficult for local cities than for large cities. This paper takes up local city of Kanazawa as a model case and study possibilities of the universal support system for rebuilding superannuated condominiums. Kanazawa is a typical local core city trying to preserve historical scenery. By combining the existent rebuilding support system and an urgent type interest supply system, we made the trial calculation that the economical burden on elderly people with small income can be mitigated. We came to conclude that giving public financial support to rebuilding project is a required policy not only to see an increase in property tax revenues but to maintain city scenery and to protect its leading industry for such local city as Kanazawa where historical scene is an important tourist attraction.
