Between 1946 and 1948, J. Gordon and Mary Schneidler subdivided and sold more than a dozen lots in a five-acre subdivision in Clyde Hill. Like many US housing projects following World War II, each deed of sale included an exclusionary racial covenant: "This property shall not be resold, leased, rented or occupied except to or by persons of the Aryan race."

In response to the community's desire to control land use development such as lot size and commercial zoning, Clyde Hill was officially incorporated as a Town on March 31, 1953. On November 10, 1998, the Council voted to organize Clyde Hill as a non-charter Code City.

In 1953 area residents voted to become an incorporated Town by a vote of 145 to 117. Ken Day defeated Don Clark for the first Clyde Hill Mayors position, 91 to 58. All initial councilmembers were elected on write-in votes.

The 1975 mayoral election between incumbent Liberino "Lib" Tufarolo and challenger Miles Nelson ended in a tie with 576 votes for each candidate. Per state law, the winner was decided through a coin flip, which brought national media attention. Nelson won the seat as he called heads.
