Why two Sioux City quotes can differ
Electrical
Running power to a detached garage costs $1,000-$3,800 for a standard build and $5,000 or more for a long trench or amperage upgrade (Angi, Trusscore).
Size and finish level
HomeGuide puts a 2-car detached garage at $20,000-$57,600, with the spread driven by how finished it is.
Foundation
A slab is cheapest. A frost-depth foundation in cold states costs more.
Climate in Sioux City: timing your detached garage job
We use NOAA's 1991-2020 climate normals for Sioux City Gateway Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.
May through September is the stretch where pouring concrete runs into the fewest weather problems in Sioux City (5 of 12 months). January, February, March, April, 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.
Sioux City gets about 29 inches of precipitation in a normal year, including roughly 36 inches of snow. The wettest months are May, June and August (4.3 inches in June). Inside the workable window, July and September are the driest, at 3.4 and 2.8 inches. The station averages about 25 days a year at 90°F or above.
Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.

Sioux City labor market for detached garage
Wages are the part of this estimate that changes most from town to town. 5 trades carry the job here, and each is compared with its US median. The weighted result for Sioux City is 0.94 times the national level.
For carpenters (47-2031, weighted 45%) the local median is $24.57 an hour, which is 16% below the national $29.12. The middle half of them earn between $22.02 and $29.52 an hour. BLS counts 350 of them working in the area, 46.7 for every 10,000 jobs (US: 43.1), so the local bench is about average.
Construction laborers (47-2061), 20% of the weighting: a median of $23.38 an hour, 3% above the US median of $22.66. The middle half of them earn between $21.71 and $28.72 an hour. About 560 work in the metro. That is 74.7 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
For cement masons and concrete finishers (47-2051, weighted 15%) the local median is $27.60 an hour, which is in line with the national $27.41. The middle half of them earn between $22.32 and $28.75 an hour. BLS counts 120 of them working in the area, 16.0 for every 10,000 jobs (US: 13.3), so the local bench is deeper than average.
Electricians (47-2111), 10% of the weighting: a median of $35.54 an hour, 17% above the US median of $30.38. The middle half of them earn between $23.43 and $40.83 an hour. About 300 work in the metro. That is 40.0 per 10,000 jobs, compared with 48.7 nationally, so expect fewer local crews to bid.
For roofers (47-2181, weighted 10%) the local median is $22.62 an hour, which is 15% below the national $26.65. The middle half of them earn between $18.46 and $27.56 an hour. BLS counts 90 of them working in the area, 12.0 for every 10,000 jobs (US: 8.7), so the local bench is deeper than average.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($29.52 an hour) instead of the median, the labor line grows by about $1,650. At the 25th percentile ($22.02) it shrinks by about $850. The total moves by 4.0% or 2.1%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 75,010 jobs in the Sioux City area. That makes it the 247th largest of the 300 metros we cover, with 0.05% of US employment.
