Mountain Park was incorporated in 1927. When it was incorporated, it did not have any people designated as residents. Circa 1945, the community had 241 people registered as voters who originated from different places in the United States, while 12 people lived in the community full time.
By 2021 there was a movement for Mountain Park to disincorporate so it could be merged into a larger city.
