Why two Michigan 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).
Detached garage cost by metro in Michigan
4 of the 10 metros sit above the statewide midpoint of $43,800, and the top-to-bottom gap is 13%. 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 |
|---|---|---|---|
| Detroit, MI | $30,800 – $61,800 | $46,300 | +6% |
| Flint, MI | $29,600 – $59,400 | $44,500 | +1% |

| Kalamazoo, MI | $28,300 – $56,900 | $42,600 | −3% |
| Traverse City, MI | $27,900 – $56,000 | $41,900 | −4% |

When Michigan weather lets you build
Weather decides when pouring concrete can happen, and Michigan 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.
Detroit has the longest comfortable season of the metros we cover in Michigan at 6 months (May through October); Flint has the shortest at 5 (May through September). Rainfall runs from 29 inches a year in Traverse City to 42 inches in Niles.
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 |
|---|---|---|---|---|
| Detroit | 20 | 84 | 30 | 6: May through October |
| Grand Rapids | 17 | 82 | 40 | 5: May through September |

Michigan labor market for detached garage
Michigan'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 1.05 times the national level.
Carpenters (47-2031), 45% of the weighting: a median of $29.66 an hour, in line with the US median of $29.12. The middle half of them earn between $23.80 and $35.09 an hour. About 18,590 work in the state. That is 42.2 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 $23.84 an hour, which is 5% above the national $22.66. The middle half of them earn between $21.52 and $29.68 an hour. BLS counts 28,490 of them working in the state, 64.7 for every 10,000 jobs (US: 70.5), so the local bench is about average.
Cement masons and concrete finishers (47-2051), 15% of the weighting: a median of $28.78 an hour, 5% above the US median of $27.41. The middle half of them earn between $23.31 and $31.00 an hour. About 6,350 work in the state. That is 14.4 per 10,000 jobs, compared with 13.3 nationally, so the supply of crews looks typical.
For electricians (47-2111, weighted 10%) the local median is $36.67 an hour, which is 21% above the national $30.38. The middle half of them earn between $24.21 and $44.38 an hour. BLS counts 23,530 of them working in the state, 53.4 for every 10,000 jobs (US: 48.7), so the local bench is about average.
Roofers (47-2181), 10% of the weighting: a median of $28.62 an hour, 7% above the US median of $26.65. The middle half of them earn between $23.02 and $37.56 an hour. About 3,090 work in the state. That is 7.0 per 10,000 jobs, compared with 8.7 nationally, so expect fewer local crews to bid.
A crew paid at the 75th percentile for carpenters ($35.09 an hour) would add about $1,800 to the statewide midpoint; one at the 25th percentile ($23.80) would take off about $1,950. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 4,403,730 jobs across Michigan (May 2025), which is 2.8% of US employment.
