Cal. Welf. & Inst. Code § 4725

(a) “Access” means the right to inspect, review, and obtain an accurate copy of any record obtained in the course of providing services under this division. A service agency may make a reasonable charge in an amount not to exceed the actual cost of reproducing the record, unless the imposition of the cost would prohibit the exercise of the right to obtain a copy. No charge may be made to search for or retrieve any record.

(b) “Record” means any item of information directly relating to a person with developmental disabilities or to one who is believed to have a developmental disability which is maintained by a service agency, whether recorded by handwriting, print, tapes, film, microfilm, or other means.
