Where the San Diego price comes from
The wage side of the estimate leans on insulation workers, floor, ceiling and wall, who do 80% of the hours on a typical job. Their local median is $23.48 an hour. Add the other trades involved and the blended wage index for San Diego is 1.04 (US = 1.00), which puts labor at 35% of the total. BLS does not publish this trade for the metro, so we used the California statewide median.
Materials are scaled with BEA's regional price parity for goods. San Diego is at 108.0 against 100 for the US, so a materials line of $1,600 nationally becomes $1,750 here (midpoint, 1,000 sq ft). Permits follow the all-items index of 111.9: $0 to $0.
Data note: 80% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in San Diego. The wage table below marks each row.

Who does the work: San Diego trade wages
The labor line is built from BLS wage data, one trade at a time. This job draws on 2 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 San Diego the blend is 1.04.
Insulation workers, floor, ceiling and wall (47-2131) carry 80% of the labor weighting. BLS does not publish this trade for the San Diego metro, so we used the California statewide median: $23.48 an hour against $23.62 for the US. The middle half of them earn between $21.78 and $35.41 an hour.
For construction laborers (47-2061, weighted 20%) the local median is $27.49 an hour, which is 21% above the national $22.66. The middle half of them earn between $23.31 and $34.32 an hour. BLS counts 8,850 of them working in the area, 57.5 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
A quick sensitivity check: moving the lead trade (insulation workers, floor, ceiling and wall) from the median to the 75th percentile wage adds about $360 to the midpoint estimate; the 25th percentile takes off about $50. That is a swing of roughly 1.9% to 13.7% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
San Diego-Chula Vista-Carlsbad has 1,538,060 jobs in total (BLS, May 2025), ranking 18th by size among the 300 metros on this site.
