Other Minnesota jobs that often go with home addition
Each project weights the trades differently, so Minnesota's wage level does not push every price by the same amount. Compared with the US midpoint, roof replacement is +21% and kitchen remodel +4%.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Kitchen remodel | 120 sq ft | $19,200 – $32,700 | +4% |

Minnesota seasons and home addition
Weather decides when digging and ground work can happen, and Minnesota 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.
Minneapolis has the longest comfortable season of the metros we cover in Minnesota at 7 months (April through October); St. Cloud has the shortest at 6 (May through October). Rainfall runs from 28 inches a year in St. Cloud to 35 inches in Rochester.
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 |
|---|---|---|---|---|
| Minneapolis | 8 | 83 | 34 | 7: April through October |
| Duluth | 2 | 78 | 31 | 6: May through October |
| Rochester | 7 | 80 | 35 | 7: April through October |
| St. Cloud | 3 | 82 | 28 | 6: May through October |
Wages behind the Minnesota number
Minnesota's labor line is priced from 6 trades, each compared with its US median wage. After weighting by each trade's share of the work, the state comes out at 1.16 times the national level.
Carpenters (47-2031), 50% of the weighting: a median of $31.22 an hour, 7% above the US median of $29.12. The middle half of them earn between $26.56 and $40.58 an hour. About 14,930 work in the state. That is 50.6 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $32.13 an hour, 17% above the US median of $27.41. The middle half of them earn between $28.81 and $38.21 an hour. About 3,070 work in the state. That is 10.4 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 $37.58 an hour, which is 24% above the national $30.38. The middle half of them earn between $28.09 and $48.76 an hour. BLS counts 14,350 of them working in the state, 48.6 for every 10,000 jobs (US: 48.7), so the local bench is about average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $45.39 an hour, 48% above the US median of $30.67. The middle half of them earn between $29.40 and $52.29 an hour. About 10,720 work in the state. That is 36.3 per 10,000 jobs, compared with 30.0 nationally, which suggests plenty of local crews to bid.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $29.46 an hour, which is 4% above the national $28.33. The middle half of them earn between $27.86 and $37.31 an hour. BLS counts 1,050 of them working in the state, 3.6 for every 10,000 jobs (US: 5.3), so the local bench is thinner than average.
Roofers (47-2181), 10% of the weighting: a median of $35.81 an hour, 34% above the US median of $26.65. The middle half of them earn between $26.76 and $44.05 an hour. About 1,890 work in the state. That is 6.4 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 ($40.58 an hour) would add about $6,150 to the statewide midpoint; one at the 25th percentile ($26.56) would take off about $3,050. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 2,949,820 jobs across Minnesota (May 2025), which is 1.9% of US employment.

Home addition cost by metro in Minnesota
1 of the 4 metros sit above the statewide midpoint of $63,800, and the top-to-bottom gap is 12%. 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 (300 sq ft) | Midpoint | vs. state |
|---|---|---|---|
| Minneapolis, MN | $45,300 – $91,700 | $68,500 | +7% |
| Rochester, MN | $40,600 – $82,200 | $61,400 | −4% |
| St. Cloud, MN | $40,600 – $82,100 | $61,300 | −4% |
| Duluth, MN | $40,500 – $81,800 | $61,100 | −4% |
Why two Minnesota quotes can differ
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).
Plumbing and fixtures
Adding a bathroom or kitchen drives the price up the most.
Permits
Construction permits run $500-$2,000, or $5-$21 per $1,000 of project cost (HomeGuide).
Foundation
A foundation, framing, roofing and matching exterior finishes all have to be built before the interior work starts.
Basic, standard or premium: Minnesota prices
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 bump-out (100 sq ft) to large suite (600 sq ft).
Basic
$42,200 to $59,500
Bump-out or simple room without plumbing
Standard
$55,200 to $72,500
Standard room addition with HVAC and electrical
Premium
$68,100 to $85,400
Large addition with bath or kitchen and a new foundation
| Size | Basic | Standard | Premium |
|---|---|---|---|
| bump-out (100 sq ft) | $14,400 – $20,600 | $19,000 – $25,200 | $23,600 – $29,800 |
| 20x20 room (400 sq ft) | $56,100 – $79,000 | $73,300 – $96,100 | $90,400 – $113,000 |
| large suite (600 sq ft) | $83,900 – $118,000 | $109,500 – $143,500 | $135,000 – $169,000 |
