2002–2021: Foundation and amateur era Kowloon City District Sports Association was established in 2002. The football team was formed as part of a widespread initiative by the
Hong Kong Football Association to involve district councils in the local football league system. For the first two decades of its existence, the club functioned as an amateur team, primarily competing in the
Hong Kong Third Division League. During this period, the club served mainly as a recreational outlet for local players and focused on community engagement rather than professional competition.
2021–2024: The "EnGenius" era and rapid rise A turning point came in the 2021–22 season when the club secured sponsorship from EnGenius and rebranded as
EnGenius Kowloon City (). The injection of resources allowed the club to recruit experienced former professional players. In the 2021–22
Hong Kong Second Division League, the team sat at the top of the table before the season was prematurely cancelled due to the
COVID-19 pandemic. Recognizing their ambition and performance, the HKFA accepted Kowloon City's application for promotion to the
Hong Kong First Division League for the 2022–23 season. In their debut season in the second tier, they finished as runners-up, narrowly missing out on the title. The following season (2023–24), Kowloon City dominated the First Division, clinching the championship and earning a historic promotion to the
Hong Kong Premier League.
2024–Present: Professionalisation The 2024–25 season marked Kowloon City's debut in the top flight of Hong Kong football. The club transitioned to a professional setup, removing the "EnGenius" sponsor name from the club title to return to its roots as
Kowloon City. They made significant signings, bringing in foreign talents from Brazil and South Korea, as well as experienced local players to compete at the highest level. ==Stadium==
