Boulder was first home to Native Americans who had a village nearby. The first non-native settlement was established in 1858 by gold seekers. The Boulder City Town Company was created a year later with lots that had a purchase price of $1,000, which was lowered to bring in more residents. The government was formalized in 1871 when the town was incorporated.

By 1880, Boulder had a population of more than 3,000. Many trainees came to the area after World War II as business people and students, joining veterans attending the University. Prior to this, the population had not grown since the 1920s.
