Why Boise costs more than the rest of Idaho
Boise carries roughly a 10% premium over the Idaho statewide figure. Three things drive that gap. Metro wages run above the state average, and labor is about 40% 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, Idaho averages $4,320 to $9,120 installed, against $4,752 to $10,032 inside Boise. Suburbs on the metro fringe usually fall between the two.

Permits in Boise
A residential permit for this work typically runs around $400 in Idaho, and metro jurisdictions like Boise 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 Boise building department before work begins.
Hiring in Boise
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 Idaho.
