Why Las Vegas prices look the way they do

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 Las Vegas the blended ratio comes out at 1.01.
Materials are scaled with BEA's regional price parity for goods. Las Vegas is at 96.3 against 100 for the US, so a materials line of $18,000 nationally becomes $17,300 here (midpoint, 300 sq ft). Permits follow the all-items index of 100.2: $500 to $2,000.

What local crews earn in Las Vegas
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 Vegas the blend is 1.01.
Carpenters (47-2031), 50% of the weighting: a median of $29.99 an hour, in line with the US median of $29.12. The middle half of them earn between $24.25 and $39.81 an hour. About 9,310 work in the metro. That is 81.9 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 $29.26 an hour, 7% above the US median of $27.41. The middle half of them earn between $24.73 and $35.51 an hour. About 2,280 work in the metro. That is 20.1 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 $34.08 an hour, which is 12% above the national $30.38. The middle half of them earn between $23.26 and $46.72 an hour. BLS counts 5,730 of them working in the area, 50.4 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 $28.70 an hour, 6% below the US median of $30.67. The middle half of them earn between $22.78 and $42.13 an hour. About 3,800 work in the metro. That is 33.4 per 10,000 jobs, compared with 30.0 nationally, so the supply of crews looks typical.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $25.13 an hour, which is 11% below the national $28.33. The middle half of them earn between $22.47 and $30.29 an hour. BLS counts 2,340 of them working in the area, 20.6 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 $23.94 an hour, 10% below the US median of $26.65. The middle half of them earn between $23.06 and $30.58 an hour. About 1,350 work in the metro. That is 11.9 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 $6,450 to the midpoint estimate; the 25th percentile takes off about $3,750. That is a swing of roughly 6.6% to 11.3% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
