Cal. Pub. Cont. Code § 2502

If a charter provision, initiative, or ordinance of a charter city prohibits the governing board’s consideration of a project labor agreement that includes all the taxpayer protection provisions of Section 2500 for a project to be awarded by the city, or prohibits the governing board from considering whether to allocate funds to a city-funded project covered by such an agreement, then state funding or financial assistance shall not be used to support that project. This section shall not be applicable until January 1, 2015, for charter cities in which a charter provision, initiative, or ordinance in effect prior to November 1, 2011, would disqualify a project from receiving state funding or financial assistance.
