Abstract
In this paper, we attempt to understand the actual condition of the adaptation by elderly people and people with disabilities who live in privately rented housing of the public housing subsidy. The candidates for investigation are users of the public housing subsidy system. The subsidy has a fixed ceiling. The limit of the subsidy has been changed several times since the subsidy program started. In addition, the maximum amount of the subsidy varies, depending on the income of the user. The renovation cost incurred to provide the housing is influenced by the subsidy cap. Bathroom and squat toilets account for a large percentage of the renovation cost. As the modification requires old fixtures to be replaced with new ones, the cost tends to be high. Many of the house renovations include the installation of handrails in hallways and along staircases. These costs are relatively low in comparison with the replacement of fixtures.
