Where the Idaho Falls price comes from
Labor is 49% of the midpoint bill here, against 50% nationally. The mix of trades behind this job is carpenters (45%), cement masons and concrete finishers (15%), construction laborers (20%), electricians (10%), roofers (10%). We weight each trade's local median wage by that share and compare it with the national median. In Idaho Falls the blended ratio comes out at 0.92.
Materials are scaled with BEA's regional price parity for goods. Idaho Falls is at 96.2 against 100 for the US, so a materials line of $21,600 nationally becomes $20,800 here (midpoint, 576 sq ft). Permits follow the all-items index of 94.4: $140 to $470.
What local crews earn in Idaho Falls
The labor line is built from BLS wage data, one trade at a time. This job draws on 5 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 Idaho Falls the blend is 0.92.
Carpenters (47-2031), 45% of the weighting: a median of $25.07 an hour, 14% below the US median of $29.12. The middle half of them earn between $21.83 and $31.11 an hour. About 750 work in the metro. That is 91.6 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
For construction laborers (47-2061, weighted 20%) the local median is $22.05 an hour, which is in line with the national $22.66. The middle half of them earn between $18.83 and $26.56 an hour. BLS counts 970 of them working in the area, 118.5 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
Cement masons and concrete finishers (47-2051), 15% of the weighting: a median of $25.28 an hour, 8% below the US median of $27.41. The middle half of them earn between $22.44 and $28.69 an hour. About 250 work in the metro. That is 30.5 per 10,000 jobs, compared with 13.3 nationally, which suggests plenty of local crews to bid.
For electricians (47-2111, weighted 10%) the local median is $31.42 an hour, which is 3% above the national $30.38. The middle half of them earn between $23.27 and $40.07 an hour. BLS counts 540 of them working in the area, 66.0 for every 10,000 jobs (US: 48.7), so the local bench is deeper than average.
Roofers (47-2181), 10% of the weighting: a median of $26.77 an hour, in line with the US median of $26.65. The middle half of them earn between $19.28 and $29.65 an hour. About 130 work in the metro. That is 15.9 per 10,000 jobs, compared with 8.7 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $2,000 to the midpoint estimate; the 25th percentile takes off about $1,100. That is a swing of roughly 2.6% to 4.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Idaho Falls has 81,840 jobs in total (BLS, May 2025), ranking 233rd by size among the 300 metros on this site.

Idaho Falls weather and the detached garage calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Idaho Falls Fanning Fld (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For pouring concrete, the comfortable months in Idaho Falls are June through September: 4 of 12. Outside them, January, February, March, April, May, October, November and December have an average overnight low of 40°F or below.
The 40°F line is a deliberately cautious stand-in. The American Concrete Institute's cold-weather guide (ACI 306R-16) defines cold-weather concreting around an average daily air temperature below 40°F, which is colder than our test of an average overnight low at or below 40°F, so we flag a few extra shoulder months. In cold weather crews may need heated enclosures, insulating blankets or accelerated mixes, and those measures can raise a quote.
Idaho Falls gets about 10 inches of precipitation in a normal year. The wettest months are April, May and June (1.6 inches in May). Inside the workable window, July and August are the driest, at 0.5 and 0.6 inches. The station averages about 26 days a year at 90°F or above.
We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.
