In Korea, the private security industry, along with the police in charge of public security, plays an important part in maintaining social order and preventing crime. The private security industry is also developing along with economic growth, but the reality is that there are insufficient parts in terms of quality. Among the facility guards who perform most of the security work in Korea, the treatment of apartment security guards is still very poor. In 2020, the Apartment Housing Management Act was revised, and management tasks such as cleaning, separation collection, and assistance in management office work were included in the tasks of apartment security guards, and management tasks were legally added in addition to security tasks because they worked in apartment houses even though they were facility security guards.
 In this study, the main problems of apartment security were the scope of work, short-term contracts, and indirect contracts, and the following improvement measures were suggested.
 First, Article 65-2 of the Apartment Housing Management Act, which applies only to apartment security guards, should be deleted, and since apartment security guards are also facility security guards, the Security Business Act should be applied to focus on the maintenance of order, crime prevention, and risk prevention, and management should be performed by management office staff. Second, in order to prevent power abuse caused by indirect employment, the amendment to the Labor Standards Act, which includes “a person who conducts and supervises considerable work content and performance process even if he is not a party to the labor contract, and a person in a position to have substantial, specific control and influence over working conditions,” should be passed and implemented as soon as possible. Third, in order to prevent short-term contracts, local governments should expand and apply subsidies for maintaining the employment of security guards. Fourth, it is necessary to revitalize the Guards Association, an organization representing the interests of guards, to cope with unreasonable treatment of guards.
 In order for Korea's private security to continue to grow, unreasonable treatment of apartment security guards should be improved.
