In post-war Japan, rapid changes in lifestyles due to the separation of jobs and housing, motorization, and other factors have led to urban development prioritizing economic activities. As a result, the uniform townscape has led to the loss of the region's unique culture and given negative impacts on resident consciousness, such as weakening of place attachment. Against this backdrop, the importance of architectural conservation has been recognized. On the other hand, it is known that the architectural conservation described above is extremely hard due to the trait of urban development. Architecture built after the 20th century has such a trend firmly because those have not been subject to Cultural property Administration in Japan. However, the method to avoid conflicting between architectural conservation and economy has not been systematized. In this study, we focus on the optimal policy for architectural conservation. Primarily, we consider the trade-off relationship between costs and revenues. Based on both a theoretical model and actual data survey, we clarify the essential characteristics of how the owner tends to renovate their buildings. The actual data used in this study were chosen based on two rules: 1) Subject sites are municipalities that have their own architectural conservation regulations, rules, guidelines, and more. 2) Subject properties are buildings that were conserved by the regulations and more.
