Why Washington prices look the way they do
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 Washington the blended ratio comes out at 1.03.
Materials are scaled with BEA's regional price parity for goods. Washington is at 104.8 against 100 for the US, so a materials line of $21,600 nationally becomes $22,600 here (midpoint, 576 sq ft). Permits follow the all-items index of 108.9: $160 to $540.
Washington 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, Washington Reagan 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 Washington are April through June and August through November: 7 of 12. Outside them, January, February, March and December have an average overnight low of 40°F or below, and July has 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, crews often start early, wet the base and plan for faster set times.
Washington gets about 42 inches of precipitation in a normal year, including roughly 14 inches of snow. The wettest months are May, June and July (4.3 inches in July). Inside the workable window, April and November are the driest, at 3.2 and 2.9 inches. The station averages about 40 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.

What local crews earn in Washington
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 Washington the blend is 1.03.
Carpenters (47-2031), 45% of the weighting: a median of $29.23 an hour, in line with the US median of $29.12. The middle half of them earn between $26.62 and $35.56 an hour. About 13,280 work in the metro. That is 42.3 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 $22.80 an hour, which is in line with the national $22.66. The middle half of them earn between $20.07 and $27.05 an hour. BLS counts 17,710 of them working in the area, 56.5 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 $28.05 an hour, in line with the US median of $27.41. The middle half of them earn between $23.42 and $30.30 an hour. About 2,810 work in the metro. That is 9.0 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 $36.50 an hour, which is 20% above the national $30.38. The middle half of them earn between $28.40 and $49.65 an hour. BLS counts 16,580 of them working in the area, 52.9 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 $28.05 an hour, 5% above the US median of $26.65. The middle half of them earn between $23.82 and $35.51 an hour. About 1,940 work in the metro. That is 6.2 per 10,000 jobs, compared with 8.7 nationally, so expect fewer local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $2,100 to the midpoint estimate; the 25th percentile takes off about $870. That is a swing of roughly 1.9% to 4.7% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Washington-Arlington-Alexandria has 3,136,190 jobs in total (BLS, May 2025), ranking 6th by size among the 300 metros on this site.
