In 1931, during the Great Depression, the federal government enacted the Davis-Bacon Act to help workers on federal construction projects. The Davis-Bacon Act, also known as the federal prevailing wage law, sets minimum wages that must be paid to workers on federal construction projects based on local “prevailing” wages. The law was designed to help curb the displacement of families by employers who were recruiting lower-wage workers from outside local areas. Many states, including California, adopted “Little Davis-Bacon” laws applying similar requirements on state and local construction projects.

California’s current prevailing wage law requires that contractors on state and local public works projects pay their employees the general prevailing rate of per diem wages based on the classification or type of work performed by the employee in the locality where the project is located, as well as to hire apprentices enrolled in state-approved apprentice programs and to make monetary contributions for apprenticeship training.
