CA Gov't Code Section 4535.2

(a)

The maximum preference and incentive a bidder may be awarded pursuant to this chapter and any other provision of law shall be 15 percent. However, in no case shall the maximum preference and incentive cost under this chapter exceed fifty thousand dollars ($50,000) for any bid, nor shall the combined cost of preferences and incentives granted pursuant to this chapter and any other provision of law exceed one hundred thousand dollars($100,000). In those cases where the 15-percent cumulated preference and incentive cost would exceed the one hundred thousand dollar ($100,000) maximum preference and incentive cost limit, the one hundred thousand dollar ($100,000) maximum preference and incentive cost limit shall apply.

(b)

Notwithstanding the provisions of this chapter, small business bidders qualified in accordance with Section 14838 shall have precedence over nonsmall business bidders in that the application of any bidder preference for which nonsmall business bidders may be eligible, including the preference contained in this chapter, shall not result in the denial of the award to a small business bidder. This subdivision shall apply to those cases where the small business bidder is the lowest responsible bidder, as well as to those cases where the small business bidder is eligible for award as the result of application of the 5-percent small business bidder preference and incentive.
