South Dakota labor market for detached garage
South Dakota's labor line is priced from 5 trades, each compared with its US median wage. After weighting by each trade's share of the work, the state comes out at 0.86 times the national level.
Carpenters (47-2031), 45% of the weighting: a median of $23.14 an hour, 21% below the US median of $29.12. The middle half of them earn between $20.29 and $28.87 an hour. About 4,560 work in the state. That is 99.7 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 $21.98 an hour, which is 3% below the national $22.66. The middle half of them earn between $18.42 and $23.14 an hour. BLS counts 1,780 of them working in the state, 38.9 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
Cement masons and concrete finishers (47-2051), 15% of the weighting: a median of $22.67 an hour, 17% below the US median of $27.41. The middle half of them earn between $19.37 and $27.58 an hour. About 2,550 work in the state. That is 55.8 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 $29.51 an hour, which is in line with the national $30.38. The middle half of them earn between $23.87 and $34.83 an hour. BLS counts 2,980 of them working in the state, 65.2 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 $22.94 an hour, 14% below the US median of $26.65. The middle half of them earn between $18.04 and $27.53 an hour. About 400 work in the state. That is 8.7 per 10,000 jobs, compared with 8.7 nationally, so the supply of crews looks typical.
A crew paid at the 75th percentile for carpenters ($28.87 an hour) would add about $1,900 to the statewide midpoint; one at the 25th percentile ($20.29) would take off about $950. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 457,380 jobs across South Dakota (May 2025), which is 0.3% of US employment.

Detached garage cost by metro in South Dakota
1 of the 2 metros sit above the statewide midpoint of $39,500, and the top-to-bottom gap is 1%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.
| Metro | Range (576 sq ft) | Midpoint | vs. state |
|---|---|---|---|
| Sioux Falls, SD | $26,500 – $53,200 | $39,900 | +1% |
| Rapid City, SD | $26,300 – $52,800 | $39,500 | level |
Why two South Dakota quotes can differ
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.
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).
Other South Dakota jobs that often go with detached garage
Each project weights the trades differently, so South Dakota's wage level does not push every price by the same amount. Compared with the US midpoint, garage door is −7% and home addition −13%.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Concrete slab | 400 sq ft | $2,250 – $4,800 | −8% |
| Garage door | 1 door | $640 – $3,450 | −7% |
| Concrete driveway | 600 sq ft | $3,300 – $8,300 | −10% |
| Home addition | 300 sq ft | $33,000 – $66,900 | −13% |
When South Dakota weather lets you build
Weather decides when pouring concrete can happen, and South Dakota is not uniform. The table uses NOAA's 1991-2020 climate normals from the weather station nearest each metro we cover, and counts the months that are neither cold nor hot enough to complicate the job.
Every South Dakota metro on the list has 5 comfortable months, though rainfall ranges from 20 inches a year in Rapid City to 28 in Sioux Falls.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| Sioux Falls | 9 | 85 | 28 | 5: May through September |
| Rapid City | 16 | 84 | 20 | 5: May through September |
