Where the Dubuque price comes from
We price the labor side from BLS wage data for 5 trades: carpenters at 45%, cement masons and concrete finishers at 15%, construction laborers at 20%, electricians at 10%, roofers at 10%. Weighted together, Dubuque wages are 0.99 times the national level. Labor makes up about 51% of the midpoint estimate (50% at national prices).
Materials are scaled with BEA's regional price parity for goods. Dubuque is at 93.7 against 100 for the US, so a materials line of $21,600 nationally becomes $20,200 here (midpoint, 576 sq ft). Permits follow the all-items index of 87.3: $130 to $440.
Data note: 10% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Dubuque. The wage table below marks each row.
Dubuque 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, Dubuque Rgnl Ap (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 Dubuque are May through September: 5 of 12. Outside them, 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.
Dubuque gets about 38 inches of precipitation in a normal year, including roughly 43 inches of snow. The wettest months are May, June and July (5.2 inches in June). Inside the workable window, August and September are the driest, at 4.0 and 3.8 inches. The station averages about 6 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.

What local crews earn in Dubuque
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 Dubuque the blend is 0.99.
Carpenters (47-2031), 45% of the weighting: a median of $28.89 an hour, in line with the US median of $29.12. The middle half of them earn between $23.41 and $30.47 an hour. About 260 work in the metro. That is 44.5 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
For construction laborers (47-2061, weighted 20%) the local median is $23.46 an hour, which is 4% above the national $22.66. The middle half of them earn between $22.37 and $28.85 an hour. BLS counts 500 of them working in the area, 85.5 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 $28.08 an hour, in line with the US median of $27.41. The middle half of them earn between $25.83 and $29.82 an hour. About 110 work in the metro. That is 18.8 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 $29.86 an hour, which is in line with the national $30.38. The middle half of them earn between $22.96 and $38.68 an hour. BLS counts 210 of them working in the area, 35.9 for every 10,000 jobs (US: 48.7), so the local bench is thinner than average.
Roofers (47-2181) carry 10% of the labor weighting. BLS does not publish this trade for the Dubuque metro, so we used the Iowa statewide median: $23.39 an hour against $26.65 for the US. The middle half of them earn between $22.31 and $29.50 an hour.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $530 to the midpoint estimate; the 25th percentile takes off about $1,850. That is a swing of roughly 4.4% to 1.3% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Dubuque has 58,470 jobs in total (BLS, May 2025), ranking 292nd by size among the 300 metros on this site.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 45% | $23.41 | $28.89 | $30.47 | $29.12 | 0.99 | metro |
