Lab Technician Salary in California 2026,
$59,510 Median | BLS Data by City

The published California figure is $59,510 a year, or $28.61 an hour, per BLS OEWS May 2025 — 1.5% below the national median of $60,390 — across a band from $44,070 at the 10th percentile to $88,900 at the 90th. The row is SOC 19-4031, Chemical Technicians, which covers industrial, environmental and research laboratory work and is broader than the lab technician title.

San Francisco-Oakland-Fremont at $71,470, then San Jose-Sunnyvale-Santa Clara $67,140, Vallejo $62,470, Sacramento-Roseville-Folsom $60,870 and Oxnard-Thousand Oaks-Ventura $58,580. The Bay Area lead of roughly thirteen thousand dollars over the southern metro reflects biotech and semiconductor laboratory work, which pays above environmental and agricultural testing.

No, and confusing the two is the most common error on this topic. This page covers SOC 19-4031, Chemical Technicians, who work in industrial, environmental and research laboratories and require no California licence. Clinical laboratory personnel — the people who run patient specimens — fall under SOC 29-2012 and are licensed by the California Department of Public Health's Laboratory Field Services, whose requirements are among the strictest in the United States. Different occupation, different regulator, different pay.

Not on this wage row. Chemical technicians working in industrial, environmental and research laboratories are unlicensed in California; employers screen on degree, instrumentation experience and quality-system familiarity instead. The picture changes completely for clinical work: anyone testing patient specimens in California needs a CDPH Laboratory Field Services licence, and the state does not recognise several credentials that other states accept, which is a well-known friction for technicians relocating here.

Because supply is ample and the employer mix is broad. A location quotient of 1.01 says the state employs technicians at almost exactly the national rate, and California's public university and community college systems produce a steady stream of science graduates who take technician roles. The occupation also spans employers with very different economics — a biotech process laboratory in the Bay Area and an agricultural testing laboratory in the Central Valley are in the same category — and the lower-paying half of that mix is large in this state.

Because 'lab technician' is a description of a workplace, not an occupation, and the wage data splits it in a way most job postings do not. SOC 19-4031 covers chemical technicians in industry and research; clinical laboratory work is elsewhere; biological technicians are elsewhere again. In California the split has a regulatory consequence too, since one branch is unlicensed and the other requires a CDPH licence with strict education and training requirements. Anyone using this page to benchmark an offer needs to establish which branch the offer belongs to first.

The category is genuinely heterogeneous and the median hides it. Environmental compliance testing, agricultural and food laboratories, semiconductor materials work and biotech process development all sit inside this row with quite different pay structures, and the $44,070 to $88,900 band is the visible consequence. A second issue is contract employment: a substantial share of California laboratory technician work — particularly in biotech — is staffed through agencies on fixed-term contracts, and those arrangements are captured unevenly by a wage survey.

Sector first. Biotech and semiconductor laboratories in the Bay Area pay above environmental and agricultural testing, which is most of the distance from the $49,810 twenty-fifth percentile to the $73,680 seventy-fifth. Then instrumentation depth — technicians who own a chromatography, spectrometry or sequencing platform and can troubleshoot it are scarcer than generalists. Then quality-system responsibility, since GMP, GLP and California's own environmental testing accreditation requirements make documented compliance a paid skill. And then supervision, which is what the $88,900 ninetieth percentile describes.
