What is behind the Fargo number

Labor is 68% 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 Fargo the blended ratio comes out at 1.00.

Materials are scaled with BEA's regional price parity for goods. Fargo is at 95.7 against 100 for the US, so a materials line of $18,000 nationally becomes $17,200 here (midpoint, 300 sq ft). Permits follow the all-items index of 90.9: $450 to $1,800.

The best months for home addition in Fargo

Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Fargo Hector Intl Ap (5 miles from the city center). 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 Fargo are May through October: 6 of 12. Outside them, January, February, March, April, November and December have an average overnight low at or below freezing (32°F).

In January, February, March, April, November 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 172 days a year with a low at or below 32°F at this station.

Fargo gets about 24 inches of precipitation in a normal year, including roughly 51 inches of snow. The wettest months are May, June and July (4.3 inches in June). Inside the workable window, August and October are the driest, at 2.6 and 2.2 inches. The station averages about 11 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.

Who does the work: Fargo trade wages

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 Fargo the blend is 1.00.

Carpenters (47-2031), 50% of the weighting: a median of $28.34 an hour, in line with the US median of $29.12. The middle half of them earn between $23.34 and $31.06 an hour. About 880 work in the metro. That is 59.2 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 $27.51 an hour, in line with the US median of $27.41. The middle half of them earn between $24.11 and $30.18 an hour. About 520 work in the metro. That is 35.0 per 10,000 jobs, compared with 13.3 nationally, which suggests plenty of local crews to bid.

For electricians (47-2111, weighted 10%) the local median is $36.99 an hour, which is 22% above the national $30.38. The middle half of them earn between $27.64 and $39.69 an hour. BLS counts 920 of them working in the area, 61.9 for every 10,000 jobs (US: 48.7), so the local bench is deeper than average.

Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $30.46 an hour, in line with the US median of $30.67. The middle half of them earn between $23.88 and $37.98 an hour. About 670 work in the metro. That is 45.1 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 $23.05 an hour, which is 19% below the national $28.33. The middle half of them earn between $21.07 and $26.67 an hour. BLS counts 70 of them working in the area, 4.7 for every 10,000 jobs (US: 5.3), so the local bench is about average.

Roofers (47-2181), 10% of the weighting: a median of $29.62 an hour, 11% above the US median of $26.65. The middle half of them earn between $23.08 and $34.68 an hour. About 130 work in the metro. That is 8.7 per 10,000 jobs, compared with 8.7 nationally, so the supply of crews looks typical.

A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $1,800 to the midpoint estimate; the 25th percentile takes off about $3,300. That is a swing of roughly 5.8% to 3.2% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Fargo has 148,660 jobs in total (BLS, May 2025), ranking 156th by size among the 300 metros on this site.

Why two Fargo quotes can differ

  • 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.

Where these numbers come from

Base prices are national ranges from the sources below. We scale labor by local BLS wages, materials by BEA goods prices and permits by the BEA all-items price level. Full method on the methodology page.

Note on derived figures: Materials = 32% of the installed price, from Cost to Renovate's mid-range 'Structural' category split (56% labor, 32% materials, 11% permits and design). It is a category average rather than an addition-specific figure.
