What is behind the Spokane number

The wage side of the estimate leans on insulation workers, floor, ceiling and wall, who do 80% of the hours on a typical job. Their local median is $29.66 an hour. Add the other trades involved and the blended wage index for Spokane is 1.22 (US = 1.00), which puts labor at 40% of the total.

Materials are scaled with BEA's regional price parity for goods. Spokane is at 105.0 against 100 for the US, so a materials line of $1,600 nationally becomes $1,700 here (midpoint, 1,000 sq ft). Permits follow the all-items index of 100.3: $0 to $0.

What local crews earn in Spokane

The labor line is built from BLS wage data, one trade at a time. This job draws on 2 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Spokane the blend is 1.22.

For insulation workers, floor, ceiling and wall (47-2131, weighted 80%) the local median is $29.66 an hour, which is 26% above the national $23.62. The middle half of them earn between $24.79 and $39.39 an hour. BLS counts 150 of them working in the area, 5.9 for every 10,000 jobs (US: 2.9), so the local bench is deeper than average.

For construction laborers (47-2061, weighted 20%) the local median is $24.53 an hour, which is 8% above the national $22.66. The middle half of them earn between $21.24 and $31.37 an hour. BLS counts 1,700 of them working in the area, 66.5 for every 10,000 jobs (US: 70.5), so the local bench is about average.

A quick sensitivity check: moving the lead trade (insulation workers, floor, ceiling and wall) from the median to the 75th percentile wage adds about $300 to the midpoint estimate; the 25th percentile takes off about $150. That is a swing of roughly 5.3% to 10.7% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Spokane-Spokane Valley has 255,820 jobs in total (BLS, May 2025), ranking 101st by size among the 300 metros on this site.
