If you mean health coverage benefits, I don't know if California has any statutes mandating benefits for same sex relationships, but it's possible. Check the state statutes for that (if a legal spouse can be of the same sex).
If there is such legislation, then insured plans must comply. In the absence of such legislation, if a plan is fully insured then the carrier would determine if it would allow domestic partners to be eligible. If the plan is self-funded, then it can do what it wants relative to eligibility of domestic partners, common-law spouses, etc.
This may be more information than you need, but if you are writing domestic partners into a plan, there are many other areas that need to be addressed such as COBRA (rules do not require domestic partners to be offered COBRA, but a plan can do so), FMLA and dependents of the domestic partner.
