Where the Sacramento price comes from
Labor is 69% 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 Sacramento the blended ratio comes out at 1.16.
Materials are scaled with BEA's regional price parity for goods. Sacramento is at 105.2 against 100 for the US, so a materials line of $18,000 nationally becomes $18,900 here (midpoint, 300 sq ft). Permits follow the all-items index of 106.7: $530 to $2,150.

Who does the work: Sacramento 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 Sacramento the blend is 1.16.
Carpenters (47-2031), 50% of the weighting: a median of $35.79 an hour, 23% above the US median of $29.12. The middle half of them earn between $27.45 and $40.70 an hour. About 9,730 work in the metro. That is 90.0 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 $28.96 an hour, 6% above the US median of $27.41. The middle half of them earn between $23.14 and $37.93 an hour. About 2,580 work in the metro. That is 23.9 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 $35.98 an hour, which is 18% above the national $30.38. The middle half of them earn between $25.35 and $47.18 an hour. BLS counts 6,340 of them working in the area, 58.7 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 $31.35 an hour, in line with the US median of $30.67. The middle half of them earn between $27.08 and $41.03 an hour. About 3,120 work in the metro. That is 28.9 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 $30.55 an hour, which is 8% above the national $28.33. The middle half of them earn between $25.00 and $37.36 an hour. BLS counts 2,500 of them working in the area, 23.1 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 $30.44 an hour, 14% above the US median of $26.65. The middle half of them earn between $28.59 and $35.89 an hour. About 1,800 work in the metro. That is 16.7 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 $3,200 to the midpoint estimate; the 25th percentile takes off about $5,500. That is a swing of roughly 8.5% to 5.0% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
