San Jose, CA, Passed in November 2002
Prompted by the recent slaying of a transgender teen in Newark, CA, the San Jose City Council voted unanimously to add transgender people to the list of groups protected under the city's anti-discrimination policy. Councilman Ken Yeager proposed changing San Jose's harassment policy after learning about the beating death of Gwen Araujo. Members of the Bay Area Municipal Elections Committee, a gay and lesbian political advocacy group that Yeager co-founded in 1984, approached Yeager and Mayor Ron Gonzales about the amendment, which will add protections for gender identity. The law applies only to public employment.

Statewide, Signed August 2003
AB 196
Discrimination. Existing law prohibits various types of discrimination and harassment based on sex, as defined, in housing and employment. This bill would expand the prohibition on sexual discrimination and harassment by including gender, as defined, in the definition of sex. The bill would permit employers to require employees to comply with reasonable workplace appearance, grooming, and dress standards consistent with state and federal law, provided that employees are allowed to appear or dress consistently with their gender identity.
