From case studies, we estimated repair costs of long-term dwelling houses and then examined how to manage and maintain the residence effectively. The average repair cost of the target houses is about 16,400yen/month, which would be a rough indication for house maintenance. Subsidy systems become effective incentives to improve the dwelling performance. To maintain and manage houses, long-term plans are important. At the time of periodic inspections and renovation, diagnosis and advice by experts such as architects are needed. Experts such as builders who related with residents continuously in small repairs are important, too.
