Most of housing and industrial mixed land use areas are convenient and easy to live, but the environment of these areas is not so good. Therefore, at these areas, it is necessary to be in good conditions for coexisting with residence and factory. In this paper I consider and evaluate local laws to be in good conditions for coexisting with residence and factory. I picked up some local laws treated with the coexistence. They are the law on the requlation of facilities to worsen their living environment in Amagasaki City, the law on the prevention of environmental pollution in Higashi-Osaka City and the law on the self-control of environmental pollution in Sumida Ward.
