The Office of Weights and Measures primary purpose is to ensure that "equity prevails" in the marketplace. The inspector is a "third party" to virtually any transaction you make based upon our inspection activities. We are responsible for ensuring the accuracy of each meter and scale that determines a charge to the consumer. We ensure that all packaged products contain the correct stated net weight or measure, and that you are charged the advertised or shelf price to assure agreement with the price determined by scanners at the checkout area.

If you have a general question about Weights and Measures, please call (510) 268-7343.

If you believe you have received short weight, measure or been overcharged, please call (510) 268-7343.
