San Joaquin County has adopted the Uniform Public Construction Cost Accounting Act (UPCCAA) and invites all interested California licensed contractors to submit their company for inclusion on the County’s Informal Bidding Contractors List for each respective calendar year.

Per California Public Contract Code 22032, any Public Works Project that is estimated to be below $175,000 is subject to the Informal Bidding Procedures set forth by the State of California Uniform Construction Cost Accounting Commission. All trade categories are subject to Informal Bidding Procedures. Contractors that are interested in being on the Informal Bidding Contractors List are required to have a current license and are subject to verification through the Contractors State License Board.
