Bands overlap on purpose, since a good standard job can cost as much as a light premium one. Below are the three bands for the default size, then a grid from 1-car (12x20), 240 sq ft to 3-car (900 sq ft).
Basic
$29,700 to $41,700
Basic shell: slab, framing, siding, a roll-up door
Standard
$38,700 to $50,700
Finished exterior, insulated, electrical and a nicer door

Why two Maryland 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).
Related projects, priced for Maryland
Each project weights the trades differently, so Maryland's wage level does not push every price by the same amount. Compared with the US midpoint, garage door is +4% and concrete driveway −2%.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Concrete slab | 400 sq ft | $2,450 – $5,200 | level |
| Garage door | 1 door | $730 – $3,850 | +4% |
| Concrete driveway | 600 sq ft | $3,600 – $9,000 | −2% |
| Home addition | 300 sq ft | $39,100 – $79,300 | +3% |
What carpenters and the other trades earn in Maryland
Maryland'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 1.03 times the national level.
Carpenters (47-2031), 45% of the weighting: a median of $30.27 an hour, 4% above the US median of $29.12. The middle half of them earn between $25.11 and $36.93 an hour. About 9,770 work in the state. That is 35.4 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.
For construction laborers (47-2061, weighted 20%) the local median is $22.58 an hour, which is in line with the national $22.66. The middle half of them earn between $18.98 and $26.70 an hour. BLS counts 20,920 of them working in the state, 75.7 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 $24.98 an hour, 9% below the US median of $27.41. The middle half of them earn between $22.75 and $28.44 an hour. About 2,540 work in the state. That is 9.2 per 10,000 jobs, compared with 13.3 nationally, so expect fewer local crews to bid.
For electricians (47-2111, weighted 10%) the local median is $35.33 an hour, which is 16% above the national $30.38. The middle half of them earn between $27.73 and $46.16 an hour. BLS counts 13,690 of them working in the state, 49.5 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 $28.89 an hour, 8% above the US median of $26.65. The middle half of them earn between $23.20 and $36.08 an hour. About 2,050 work in the state. That is 7.4 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 ($36.93 an hour) would add about $2,200 to the statewide midpoint; one at the 25th percentile ($25.11) would take off about $1,700. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 2,763,030 jobs across Maryland (May 2025), which is 1.8% of US employment.

Maryland metro-by-metro prices
0 of the 3 metros sit above the statewide midpoint of $44,700, and the top-to-bottom gap is 7%. 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 |
|---|---|---|---|
| Baltimore, MD | $29,300 – $58,900 | $44,100 | −1% |
| Lexington Park, MD | $28,900 – $58,100 | $43,500 | −3% |
| Hagerstown, MD | $27,500 – $55,200 | $41,300 | −8% |
Weather windows across Maryland
Weather decides when pouring concrete can happen, and Maryland 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.
Lexington Park has the longest comfortable season of the metros we cover in Maryland at 8 months (April through November); Hagerstown has the shortest at 7 (April through October). Rainfall runs from 44 inches a year in Hagerstown to 45 inches in Lexington Park.
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 |
|---|---|---|---|---|
| Baltimore | 30 | 90 | 44 | 7: April through June and August through November |
| Hagerstown | 22 | 86 | 44 | 7: April through October |
| Lexington Park | 30 | 87 | 45 | 8: April through November |
