Fresno weather and the home addition calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Fresno Yosemite Intl Ap (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.

What local crews earn in Fresno
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 Fresno the blend is 1.06.
Carpenters (47-2031), 50% of the weighting: a median of $30.52 an hour, 5% above the US median of $29.12. The middle half of them earn between $23.62 and $39.23 an hour. About 1,790 work in the metro. That is 37.5 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $27.70 an hour, in line with the US median of $27.41. The middle half of them earn between $22.89 and $35.00 an hour. About 980 work in the metro. That is 20.5 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 $34.48 an hour, which is 13% above the national $30.38. The middle half of them earn between $27.48 and $45.69 an hour. BLS counts 1,980 of them working in the area, 41.5 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 $30.96 an hour, in line with the US median of $30.67. The middle half of them earn between $24.66 and $44.86 an hour. About 970 work in the metro. That is 20.3 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 $29.94 an hour, which is 6% above the national $28.33. The middle half of them earn between $24.50 and $46.01 an hour. BLS counts 800 of them working in the area, 16.8 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 $30.00 an hour, 13% above the US median of $26.65. The middle half of them earn between $28.20 and $31.06 an hour. About 640 work in the metro. That is 13.4 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 $5,700 to the midpoint estimate; the 25th percentile takes off about $4,550. That is a swing of roughly 7.5% to 9.4% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Fresno has 476,890 jobs in total (BLS, May 2025), ranking 53rd by size among the 300 metros on this site.
