Where the Iowa City 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 Iowa City the blended ratio comes out at 0.91.
On the materials line, the BEA goods price index for the Iowa City metro is 93.7 (US = 100). The midpoint materials bill for 576 sq ft comes to $20,200, compared with $21,600 at national prices. Permit and inspection fees are scaled by the broader index (91.5) and land at $140 to $460.
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 Iowa City. The wage table below marks each row.
Why two Iowa City quotes can differ
Garage apartments
A garage with living space is a different project: HomeGuide puts them at $80,000-$300,000.
Permits
You need a permit for a detached garage: $150-$500 on average, with separate electrical or plumbing permits if those are involved.
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).

Iowa 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 Iowa City is 0.91 times the national level.
For carpenters (47-2031, weighted 45%) the local median is $23.89 an hour, which is 18% below the national $29.12. The middle half of them earn between $21.98 and $29.70 an hour. BLS counts 360 of them working in the area, 38.4 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 $23.05 an hour, in line with the US median of $22.66. The middle half of them earn between $21.87 and $28.74 an hour. About 800 work in the metro. That is 85.3 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.
For cement masons and concrete finishers (47-2051, weighted 15%) the local median is $27.95 an hour, which is in line with the national $27.41. The middle half of them earn between $24.95 and $29.32 an hour. BLS counts 80 of them working in the area, 8.5 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.
Electricians (47-2111), 10% of the weighting: a median of $28.61 an hour, 6% below the US median of $30.38. The middle half of them earn between $21.93 and $34.19 an hour. About 370 work in the metro. That is 39.5 per 10,000 jobs, compared with 48.7 nationally, so expect fewer local crews to bid.
Roofers (47-2181) carry 10% of the labor weighting. BLS does not publish this trade for the Iowa City 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.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($29.70 an hour) instead of the median, the labor line grows by about $1,950. At the 25th percentile ($21.98) it shrinks by about $640. The total moves by 4.8% or 1.6%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 93,760 jobs in the Iowa City area. That makes it the 214th largest of the 300 metros we cover, with 0.06% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 45% | $21.98 | $23.89 | $29.70 | $29.12 | 0.82 | metro |

Climate in Iowa City: timing your detached garage job
We use NOAA's 1991-2020 climate normals for Iowa City Muni Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.
May through October is the stretch where pouring concrete runs into the fewest weather problems in Iowa City (6 of 12 months). January, February, March, April, 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.
Iowa City gets about 36 inches of precipitation in a normal year. The wettest months are May, June and August (5.3 inches in June). Inside the workable window, September and October are the driest, at 3.2 and 3.0 inches. The station averages about 19 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.
