Why San Francisco prices look the way they do
Labor is 60% of the midpoint bill here, against 52% nationally. The mix of trades behind this job is plumbers, pipefitters and steamfitters (40%), construction laborers (40%), operating engineers and other construction equipment operators (20%). We weight each trade's local median wage by that share and compare it with the national median. In San Francisco the blended ratio comes out at 1.52.
Materials are scaled with BEA's regional price parity for goods. San Francisco is at 108.5 against 100 for the US, so a materials line of $3,350 nationally becomes $3,650 here (midpoint, 4,000 sq ft of lawn). Permits follow the all-items index of 115.6: $0 to $0.
San Francisco weather and the sprinkler system calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, San Francisco Dwtn (in the city). They are 30-year averages, so any one year can run hotter, colder or wetter.
Weather is not a serious constraint for digging, grading and setting material in the ground in San Francisco: no month in the averages is cold enough (an average overnight low at or below freezing (32°F)) or hot enough (an average daytime high of 90°F or more) to rule it out, so the workable window is all year.
San Francisco gets about 23 inches of precipitation in a normal year. The wettest months are January, February and December (4.8 inches in December). The station averages about 3 days a year at 90°F or above.
We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.

Backflow and permits
Backflow preventers and plumbing permits are local rules; check with your water utility.
What local crews earn in San Francisco
The labor line is built from BLS wage data, one trade at a time. This job draws on 3 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 Francisco the blend is 1.52.
Plumbers, pipefitters and steamfitters (47-2152), 40% of the weighting: a median of $37.44 an hour, 22% above the US median of $30.67. The middle half of them earn between $30.12 and $58.54 an hour. About 5,660 work in the metro. That is 23.8 per 10,000 jobs, compared with 30.0 nationally, so expect fewer local crews to bid.
For construction laborers (47-2061, weighted 40%) the local median is $34.91 an hour, which is 54% above the national $22.66. The middle half of them earn between $28.03 and $40.50 an hour. BLS counts 11,620 of them working in the area, 48.9 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
Operating engineers and other construction equipment operators (47-2073), 20% of the weighting: a median of $59.97 an hour, 108% above the US median of $28.78. The middle half of them earn between $38.08 and $64.34 an hour. About 4,080 work in the metro. That is 17.2 per 10,000 jobs, compared with 30.7 nationally, so expect fewer local crews to bid.
A quick sensitivity check: moving the lead trade (plumbers, pipefitters and steamfitters) from the median to the 75th percentile wage adds about $1,000 to the midpoint estimate; the 25th percentile takes off about $350. That is a swing of roughly 3.8% to 10.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
San Francisco-Oakland-Fremont has 2,373,920 jobs in total (BLS, May 2025), ranking 12th by size among the 300 metros on this site.
