This study aims to assess existing laws and ordinances in Korea, focusing on police cooperation, crime prevention support, and community security activities. It proposes effective improvement plans to enhance legal frameworks. Traditional crime prevention highlighted punishment and deterrence. However, attention has shifted to Crime Prevention Through Environmental Design(CPTED), focusing on proactive crime prevention by enhancing the environment. In pursuit of these improvements, several crucial steps are necessary. Firstly, it is vital to establish a dedicated foundational law tailored specifically to CPTED, delineating basic guidelines for crime prevention-related ordinances and regulations. Secondly, central and local governments must enact explicit laws mandating police involvement in crime prevention policies and projects across all regions, as police participation in CPTED projects is mandatory in only twelve metropolitan municipalities. Thirdly, while traditional CPTED-related laws prioritized strengthening physical environments and crime-prone areas according to first-generation principles, the significance of community engagement now surpassed mere surveillance and access control, credited to advancements like surveillance cameras, Lastly, in the implementation of crime prevention facilities, central and local governments must expand support targets, prioritizing comprehensive financial assistance for crime-vulnerable households and addressing multifaced issues through the enactment of fundamental laws or ordinances. This study holds significant implications, providing a foundation for suggesting diverse strategies in CPTED development thereby fortifying crime prevention strategies.
