What is behind the Tulsa number
Labor is 64% 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 Tulsa the blended ratio comes out at 0.83.
Materials are scaled with BEA's regional price parity for goods. Tulsa is at 93.8 against 100 for the US, so a materials line of $18,000 nationally becomes $16,900 here (midpoint, 300 sq ft). Permits follow the all-items index of 89.2: $450 to $1,800.
Tulsa weather and the home addition calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Tulsa 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 Tulsa are March through June and September through November: 7 of 12. Outside them, January, February and December have an average overnight low at or below freezing (32°F), and July and August have an average daytime high of 90°F or more.
In January, February 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 72 days a year with a low at or below 32°F at this station.
Tulsa gets about 41 inches of precipitation in a normal year, including roughly 9 inches of snow. The wettest months are April, May and June (5.7 inches in May). Inside the workable window, March and November are the driest, at 3.1 and 2.7 inches. The station averages about 74 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 Tulsa
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 Tulsa the blend is 0.83.
Carpenters (47-2031), 50% of the weighting: a median of $22.51 an hour, 23% below the US median of $29.12. The middle half of them earn between $20.30 and $25.03 an hour. About 1,320 work in the metro. That is 28.8 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $22.19 an hour, 19% below the US median of $27.41. The middle half of them earn between $19.29 and $23.28 an hour. About 1,140 work in the metro. That is 24.9 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 $29.94 an hour, which is in line with the national $30.38. The middle half of them earn between $23.40 and $37.18 an hour. BLS counts 2,750 of them working in the area, 59.9 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 $28.58 an hour, 7% below the US median of $30.67. The middle half of them earn between $21.89 and $35.72 an hour. About 1,950 work in the metro. That is 42.5 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 $22.15 an hour, which is 22% below the national $28.33. The middle half of them earn between $22.15 and $23.42 an hour. BLS counts 110 of them working in the area, 2.4 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 $23.72 an hour, 11% below the US median of $26.65. The middle half of them earn between $18.60 and $39.29 an hour. About 350 work in the metro. That is 7.6 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 $1,650 to the midpoint estimate; the 25th percentile takes off about $1,450. That is a swing of roughly 2.9% to 3.3% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Tulsa has 458,730 jobs in total (BLS, May 2025), ranking 54th by size among the 300 metros on this site.
