Holladay is part of the Salt Lake City, Utah Metropolitan Statistical Area. The population was 26,472 at the 2010 census, a significant increase from 14,561 in 2000. The city was incorporated on November 29, 1999 as Holladay-Cottonwood, and the name was shortened to Holladay on December 14 of that year. It was reported in the 1990 census as the Holladay-Cottonwood CDP.
Holladay is the oldest continuously inhabited settlement in Utah, since Salt Lake City was abandoned for a time in 1857 when Johnston’s Army occupied the city.
Holladay is known for large estate homes on 1+ acres lots with some of the wooded grounds and most foliage in all of Salt Lake County.
In the 1960s the Cottonwood Mall was constructed in Holladay, it being Utah’s first enclosed shopping mall. The mall was closed down in 2007 after a plan to turn the mall into a European-style outdoor shopping village was announced.
