Abstract
This study is about HPOZ –Historical Preservation Overlay Zone- and its influence on the residents in the Mar Vista Tract which was subdivided in 1948 and designated HPOZ in 2003. After HPOZ designation, the HPOZ board (consisting of four members) with support from Los Angeles City became the driving forth behind its conservation. Through the HPOZ movement, the community became well developed and the residents started to take an active interest in Mar Vista. This case study provides ideas as to how to sustain Japanese suburban housing developments and to increase good quality housing stocks.
