Abstract
In this study, the following was revealed on the public rental housing complex (PRHC) in Osaka Prefecture. 1. The number of the PRHC that doesn't meet the criteria installation rate of parking, 2. The number of the PRHC with a surplus in the parking lot, 3. Guidance situation of municipalities in the redevelopment. As a result, 87.3% of the PRHC that were built in 1965-1974 doesn't meet the installation criteria, and in addition, there is a surplus of parking lot on 90.0% of them. When the municipality applied the criteria of the current situation to redevelopment of the PRHC that doesn't meet the criteria despite the surplus of parking lot, the wasted space would be generated. Therefore the current parking installation criteria must be revised by placing the guidance for the redevelopment, to not generate a useless space.
