Sterile Processing Technician Salary in California 2026,
$61,370 Median | BLS Data by City

California sterile processing technicians earn a median $61,370 a year, $29.50 an hour, per BLS OEWS May 2025, with the middle half between $49,650 and $77,660 and a full range of $43,680 to $85,240. That is 28.7% above the $47,700 national median — the largest state premium for this role anywhere in the country.

Vallejo at $82,610, then San Francisco-Oakland-Fremont at $82,140, Santa Cruz-Watsonville at $81,370, San Jose-Sunnyvale-Santa Clara at $81,090 and Sacramento-Roseville-Folsom at $79,490. All five are Northern California markets and all five sit above the state 75th percentile of $77,660 — a concentration of high pay that has more to do with hospital labour agreements than with geography.

No. California issues no licence, registration or examination for the role, so hospitals may train into it. What employers require in practice is the Healthcare Sterile Processing Association's Certified Registered Central Service Technician credential, or the CBSPD equivalent, usually within a set period after hire — and in the large California hospital systems that credential typically attaches to a defined pay step.

California's income tax is progressive to 13.3% at the top, but a technician at the $61,370 median sits in the lower-middle brackets, so the burden is moderate. All wages carry a 1.3% State Disability Insurance contribution with no cap in 2026. The larger California cost at this income is housing — the metros paying $82,610 and $82,140 are among the most expensive in the country.

Union representation in the large Northern California hospital systems, principally. Sterile processing is covered by the same labour agreements as other hospital service classifications in much of the state, which sets scales and step increases well above what a non-union market produces. That is why Vallejo, San Francisco-Oakland-Fremont, Santa Cruz-Watsonville and San Jose-Sunnyvale-Santa Clara all cluster above eighty thousand dollars while the national median for the occupation sits at $47,700.

Two labour markets inside one state. The bottom — $43,680 at the tenth percentile, $49,650 at the twenty-fifth — is uncertified and non-union work, much of it in ambulatory surgical centres and smaller inland facilities. The top is unionised Northern California hospital employment, where the five published metros all sit above the state 75th percentile of $77,660. There is very little in between, which is why the median of $61,370 sits at an unusually large distance from both ends.

SOC 31-9093 is Medical Equipment Preparers, a close but not exact match, and it includes equipment preparation roles beyond surgical instrument processing. The $43,680 tenth percentile reflects uncertified trainee work, which California permits. And the metro figures should be read against California housing: a technician earning $82,140 in San Francisco-Oakland-Fremont is not better off than one earning considerably less in a low-cost state, once rent is accounted for.

Shift, specialty and contract. Hospital sterile processing runs around the clock, and evening, night and weekend differentials are standard and contractually defined in the unionised systems. Specialty instrumentation — orthopaedic and spine trays, robotic instruments, flexible endoscope reprocessing — attaches to higher competency grades. And where a labour agreement covers the department, step increases and differentials are set rather than negotiated individually, which is what pushes the top of the California band to $85,240.
