California layers its own certified-payroll regime on top of any federal requirements: records go to the state electronically, not just to the awarding body. The items below link to the statute and the state agency page they come from.
California Labor Code § 1776 requires each contractor and subcontractor on public works to keep accurate payroll records — name, address, social security number, work classification, straight-time and overtime hours each day and week, and actual per diem wages paid — verified by a written declaration made under penalty of perjury.

Under 29 CFR 5.5(a)(3)(ii), contractors must submit certified payrolls weekly for each week in which covered work is performed. The payroll needs only an individually identifying number for each worker — for example, the last four digits of the worker's Social Security number — and each submission carries a signed Statement of Compliance. Optional Form WH-347 satisfies the requirement.
