Occupational Therapy Assistant Salary in California 2026,
$81,770 Median | BLS Data by City

California occupational therapy assistants earn a median $81,770 a year, $39.31 an hour, per BLS OEWS May 2025, with the middle half between $76,350 and $96,720 and a full range of $65,680 to $104,990. That is 13.1% above the $72,300 national median.

San Francisco-Oakland-Fremont at $97,860, then Modesto at $96,210, San Jose-Sunnyvale-Santa Clara at $95,370, Bakersfield-Delano at $95,190 and Sacramento-Roseville-Folsom at $95,180. The Central Valley entries are the notable ones: Modesto and Bakersfield-Delano nearly match Bay Area rates because skilled nursing demand there is high and the local supply of licensed OTAs is thin.

The California Board of Occupational Therapy, within the Department of Consumer Affairs. Licensure requires graduation from an ACOTE-accredited occupational therapy assistant programme, NBCOT certification and Board application, and the Board sets the supervision requirements for practice. It also issues separate advanced practice approvals for hand therapy and physical agent modalities, which are legal scope expansions rather than voluntary certificates.

California's income tax is progressive to 13.3% and all wages carry a 1.3% State Disability Insurance contribution with no cap in 2026; at an $81,770 median an OTA sits in the middle brackets. The more useful comparison is geographic: the same salary goes considerably further in Modesto at $96,210 or Bakersfield-Delano at $95,190 than in San Francisco-Oakland-Fremont at $97,860.

They are California-specific authorisations issued by the Board of Occupational Therapy allowing an OTA to perform defined advanced techniques — hand therapy and physical agent modalities — that are otherwise outside the assistant scope of practice. Because they expand what you may legally do rather than merely signalling competence, they change what an employer can schedule you for. That makes them the clearest single route from the $81,770 median toward the $96,720 seventy-fifth percentile.

Because supply is the binding constraint, not cost of living. Modesto at $96,210 and Bakersfield-Delano at $95,190 have substantial skilled nursing and post-acute sectors serving ageing populations, and very few accredited OTA programmes nearby producing graduates. Employers there bid against the Bay Area for a small licensed pool. The result is a near-identical nominal wage in a market where housing costs a fraction of San Francisco-Oakland-Fremont's — which makes the Central Valley the best real-income market for OTAs in California.

The state sample is small at about 3,840 assistants, so percentile values move between vintages more than in a large occupation and the metro rows are thin. The figures also assume full-time work, while a substantial share of California OTA employment is per-diem or per-visit in skilled nursing and home health, where annual earnings track caseload volume. And skilled nursing productivity expectations — treatment minute targets — are a real feature of the work that the wage figure cannot show.

Board approvals, setting and geography, roughly equally. The advanced practice approvals for hand therapy and physical agent modalities expand legal scope and therefore schedulability. Setting matters next: home health pays per visit and rewards efficiency, skilled nursing pays productivity-linked rates, and school-adjacent and paediatric work pays on different structures again. And geography works unusually here — the Central Valley markets at $96,210 and $95,190 deliver close to Bay Area nominal pay against far lower living costs.
