Where the Bloomington price comes from
Labor is 69% of the midpoint bill here, against 67% nationally. The mix of trades behind this job is carpenters (50%), cement masons and concrete finishers (10%), electricians (10%), plumbers, pipefitters and steamfitters (10%), drywall and ceiling tile installers (10%), roofers (10%). We weight each trade's local median wage by that share and compare it with the national median. In Bloomington the blended ratio comes out at 1.05.
Materials are scaled with BEA's regional price parity for goods. Bloomington is at 94.3 against 100 for the US, so a materials line of $18,000 nationally becomes $17,000 here (midpoint, 300 sq ft). Permits follow the all-items index of 95.1: $480 to $1,900.
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 Bloomington. The wage table below marks each row.
Why two Bloomington quotes can differ
Permits
Construction permits run $500-$2,000, or $5-$21 per $1,000 of project cost (HomeGuide).

Type of addition
A new room is $125-$250 per sq ft; a bump-out $85-$200; an attic conversion $50-$150; a garage conversion $50-$200 (HomeGuide).
What local crews earn in Bloomington
The labor line is built from BLS wage data, one trade at a time. This job draws on 6 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 Bloomington the blend is 1.05.
Carpenters (47-2031), 50% of the weighting: a median of $29.50 an hour, in line with the US median of $29.12. The middle half of them earn between $23.82 and $35.36 an hour. About 270 work in the metro. That is 36.9 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $31.50 an hour, 15% above the US median of $27.41. The middle half of them earn between $25.64 and $32.33 an hour. About 80 work in the metro. That is 10.9 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 $31.57 an hour, which is 4% above the national $30.38. The middle half of them earn between $24.25 and $44.46 an hour. BLS counts 210 of them working in the area, 28.7 for every 10,000 jobs (US: 48.7), so the local bench is thinner than average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $46.63 an hour, 52% above the US median of $30.67. The middle half of them earn between $30.76 and $47.47 an hour. About 320 work in the metro. That is 43.7 per 10,000 jobs, compared with 30.0 nationally, which suggests plenty of local crews to bid.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the Bloomington metro, so we used the Indiana statewide median: $23.95 an hour against $28.33 for the US. The middle half of them earn between $22.04 and $30.49 an hour.
Roofers (47-2181), 10% of the weighting: a median of $23.81 an hour, 11% below the US median of $26.65. The middle half of them earn between $20.69 and $29.40 an hour. About 90 work in the metro. That is 12.3 per 10,000 jobs, compared with 8.7 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $3,850 to the midpoint estimate; the 25th percentile takes off about $3,750. That is a swing of roughly 6.4% to 6.6% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Bloomington has 73,240 jobs in total (BLS, May 2025), ranking 251st by size among the 300 metros on this site.

Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Bloomington Indiana Univ (in the city). They are 30-year averages, so any one year can run hotter, colder or wetter.
For digging, grading and setting material in the ground, the comfortable months in Bloomington are April through November: 8 of 12. Outside them, January, February, March and December have an average overnight low at or below freezing (32°F).
In January, February, March and December the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 108 days a year with a low at or below 32°F at this station.
Bloomington gets about 49 inches of precipitation in a normal year, including roughly 18 inches of snow. The wettest months are April, May and June (5.4 inches in June). Inside the workable window, August and September are the driest, at 3.4 and 3.8 inches. The station averages about 21 days a year at 90°F or above.
