What is behind the Beaumont number
We price the labor side from BLS wage data for 6 trades: carpenters at 50%, cement masons and concrete finishers at 10%, electricians at 10%, plumbers, pipefitters and steamfitters at 10%, drywall and ceiling tile installers at 10%, roofers at 10%. Weighted together, Beaumont wages are 0.92 times the national level. Labor makes up about 66% of the midpoint estimate (67% at national prices).
Materials are scaled with BEA's regional price parity for goods. Beaumont 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 90.0: $450 to $1,800.
Data note: 20% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Beaumont. The wage table below marks each row.

Who does the work: Beaumont 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 Beaumont the blend is 0.92.
Carpenters (47-2031), 50% of the weighting: a median of $28.02 an hour, 4% below the US median of $29.12. The middle half of them earn between $22.76 and $30.06 an hour. About 1,000 work in the metro. That is 61.3 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 $23.23 an hour, 15% below the US median of $27.41. The middle half of them earn between $21.17 and $28.90 an hour. About 250 work in the metro. That is 15.3 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 $29.51 an hour, which is in line with the national $30.38. The middle half of them earn between $28.04 and $36.10 an hour. BLS counts 2,000 of them working in the area, 122.5 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 $29.92 an hour, in line with the US median of $30.67. The middle half of them earn between $25.13 and $38.96 an hour. About 1,250 work in the metro. That is 76.6 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 Beaumont metro, so we used the Texas statewide median: $22.88 an hour against $28.33 for the US. The middle half of them earn between $19.28 and $28.09 an hour.
Roofers (47-2181) carry 10% of the labor weighting. BLS does not publish this trade for the Beaumont metro, so we used the Texas statewide median: $22.13 an hour against $26.65 for the US. The middle half of them earn between $18.00 and $25.78 an hour.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $1,350 to the midpoint estimate; the 25th percentile takes off about $3,450. That is a swing of roughly 6.5% to 2.5% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Beaumont-Port Arthur has 163,220 jobs in total (BLS, May 2025), ranking 144th by size among the 300 metros on this site.
