Cal. Gov. Code § 7296.4
As used in Section 7292, "a sufficient number of qualified bilingual persons in public contact positions" is the number required to provide the same level of services to non-English-speaking persons as is available to English-speaking persons seeking these services. However, where the statewide or local office or facility of the state employs the equivalent of 25 or fewer regular, full-time employees, it shall constitute compliance with the requirements of this chapter if a sufficient number of qualified bilingual persons are employed in public contact positions, or as qualified interpreters to assist those in those positions, to provide the same level of services to non-English-speaking persons as is available to English-speaking persons seeking the services from the office or facility.
