What is behind the Huntsville number
Labor is 46% 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 Huntsville the blended ratio comes out at 0.82.
Materials are scaled with BEA's regional price parity for goods. Huntsville is at 96.4 against 100 for the US, so a materials line of $21,600 nationally becomes $20,800 here (midpoint, 576 sq ft). Permits follow the all-items index of 93.1: $140 to $470.
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 Huntsville. The wage table below marks each row.
Planning more than one job in Huntsville?
Jobs that often go together with detached garage are priced below at their usual sizes, using the same Huntsville wage and price inputs. Compared with national midpoints, garage door comes out highest (−7%) and concrete driveway lowest (−14%); the gap comes from the trades each job uses.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Concrete slab | 400 sq ft | $2,200 – $4,700 | −10% |
| Garage door | 1 door | $640 – $3,450 | −7% |
| Concrete driveway | 600 sq ft | $3,200 – $7,900 | −14% |
| Home addition | 300 sq ft | $33,200 – $67,300 | −13% |
Huntsville 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, Huntsville Intl 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 Huntsville are March through June and September through November: 7 of 12. Outside them, January, February and December have an average overnight low of 40°F or below, and July and August have an average daytime high of 90°F or more.
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.
Heat matters for concrete as well. With average highs of 90°F or more in July and August, crews often start early, wet the base and plan for faster set times.
Huntsville gets about 54 inches of precipitation in a normal year, including roughly 2 inches of snow. The wettest months are February, March and December (5.9 inches in December). Inside the workable window, September and October are the driest, at 3.5 and 3.6 inches. The station averages about 62 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.
| Month | Avg high °F | Avg low °F | Precip (in) | For this job |
|---|---|---|---|---|
| Jan | 52 | 33 | 5.0 | Cold |
| Feb | 57 | 36 | 5.1 | Cold |

What local crews earn in Huntsville
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 Huntsville the blend is 0.82.
Carpenters (47-2031), 45% of the weighting: a median of $23.54 an hour, 19% below the US median of $29.12. The middle half of them earn between $20.69 and $28.06 an hour. About 430 work in the metro. That is 16.1 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 $18.03 an hour, which is 20% below the national $22.66. The middle half of them earn between $14.00 and $21.95 an hour. BLS counts 1,670 of them working in the area, 62.6 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 $22.67 an hour, 17% below the US median of $27.41. The middle half of them earn between $18.52 and $28.12 an hour. About 220 work in the metro. That is 8.3 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 $28.13 an hour, which is 7% below the national $30.38. The middle half of them earn between $22.75 and $32.00 an hour. BLS counts 1,030 of them working in the area, 38.6 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 Huntsville metro, so we used the Alabama statewide median: $21.96 an hour against $26.65 for the US. The middle half of them earn between $20.36 and $25.64 an hour.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $1,500 to the midpoint estimate; the 25th percentile takes off about $950. That is a swing of roughly 2.4% to 3.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Huntsville has 266,650 jobs in total (BLS, May 2025), ranking 99th by size among the 300 metros on this site.
