History
The community was built by the Tualatin Development Company starting in 1964. Created as a planned community for adults, King City was incorporated in March 1966. Build-out of the original 273 acres finished about 1978. Originally, King City was developed as an age-restricted community governed by the rules of the King City Civic Association (KCCA) in which people under 50 could not live in the city.

The KCCA rules were later changed to conform to the 1988 amendments to the Federal Fair Housing Act, which set the age restriction to 55 or older. Later, the city, which was at first contiguous with the boundaries of KCCA, expanded to include newer, non-age restricted developments. Future expansion to the west is planned for the city, within the limits of the Portland Metropolitan Urban Growth Boundary. In 2024, the City Council passed an annexation on the far West side of the King City Urban Growth Boundary. This annexation was approved by 100% of land owners and increased the City land area by approximately 215 acres.
