Why St. George costs more than the rest of Utah
St. George carries roughly a 4% premium over the Utah statewide figure. Three things drive that gap. Metro wages run above the state average, and labor is about 50% of this bill. Permitting and inspection are slower and more expensive inside city limits. And site access is tighter, which means smaller equipment, more hand work, and sometimes street permits for deliveries.
Statewide, Utah averages $5.94 to $11.88 per sq ft, against $6.18 to $12.36 inside St. George. Suburbs on the metro fringe usually fall between the two.
