Why Denver costs more than the rest of Colorado
Denver carries roughly a 14% premium over the Colorado 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, Colorado averages $6.18 to $12.36 per sq ft, against $7.05 to $14.09 inside Denver. Suburbs on the metro fringe usually fall between the two.

Permits in Denver
A residential permit for this work typically runs around $550 in Colorado, and metro jurisdictions like Denver usually sit at the upper end of that range with longer review times. Permit cost is rarely included in a contractor quote, so add it separately. Confirm scope with the Denver building department before work begins.
Hiring in Denver
Get three written, itemised quotes from licensed and insured contractors, and make sure each specifies the same dimensions and the same grade of material. In a metro market, the cheapest bid often reflects a thinner specification or a crew travelling in from outside the area rather than a genuine saving. Ask for local references and check that the licence is current in Colorado.
