Who does the work: Las Cruces 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 Las Cruces the blend is 0.86.
Carpenters (47-2031), 50% of the weighting: a median of $27.42 an hour, 6% below the US median of $29.12. The middle half of them earn between $21.44 and $29.32 an hour. About 250 work in the metro. That is 31.3 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 $21.72 an hour, 21% below the US median of $27.41. The middle half of them earn between $18.53 and $22.66 an hour. About 140 work in the metro. That is 17.5 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 $25.95 an hour, which is 15% below the national $30.38. The middle half of them earn between $21.71 and $29.99 an hour. BLS counts 410 of them working in the area, 51.3 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 $26.23 an hour, 14% below the US median of $30.67. The middle half of them earn between $21.03 and $34.06 an hour. About 180 work in the metro. That is 22.5 per 10,000 jobs, compared with 30.0 nationally, so expect fewer local crews to bid.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $18.26 an hour, which is 36% below the national $28.33. The middle half of them earn between $18.14 and $20.50 an hour. BLS counts 40 of them working in the area, 5.0 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 $18.78 an hour, 30% below the US median of $26.65. The middle half of them earn between $18.08 and $20.94 an hour. About 50 work in the metro. That is 6.3 per 10,000 jobs, compared with 8.7 nationally, so expect fewer local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $1,250 to the midpoint estimate; the 25th percentile takes off about $3,950. That is a swing of roughly 7.7% to 2.4% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Las Cruces has 80,000 jobs in total (BLS, May 2025), ranking 238th by size among the 300 metros on this site.
