What local crews earn in Naples
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 Naples the blend is 0.86.
Carpenters (47-2031), 50% of the weighting: a median of $23.74 an hour, 18% below the US median of $29.12. The middle half of them earn between $20.51 and $28.52 an hour. About 1,300 work in the metro. That is 74.8 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 $23.89 an hour, 13% below the US median of $27.41. The middle half of them earn between $22.65 and $27.95 an hour. About 640 work in the metro. That is 36.8 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 $28.86 an hour, which is 5% below the national $30.38. The middle half of them earn between $23.46 and $30.52 an hour. BLS counts 1,110 of them working in the area, 63.8 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 $27.80 an hour, 9% below the US median of $30.67. The middle half of them earn between $23.39 and $30.94 an hour. About 810 work in the metro. That is 46.6 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 $25.40 an hour, which is 10% below the national $28.33. The middle half of them earn between $23.29 and $28.42 an hour. BLS counts 200 of them working in the area, 11.5 for every 10,000 jobs (US: 5.3), so the local bench is deeper than average.
Roofers (47-2181), 10% of the weighting: a median of $23.76 an hour, 11% below the US median of $26.65. The middle half of them earn between $22.00 and $29.30 an hour. About 610 work in the metro. That is 35.1 per 10,000 jobs, compared with 8.7 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $3,150 to the midpoint estimate; the 25th percentile takes off about $2,100. That is a swing of roughly 4.1% to 6.1% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Naples-Marco Island has 173,880 jobs in total (BLS, May 2025), ranking 134th by size among the 300 metros on this site.
