Weights and Measures Division
Proposed changes to the County Ordinance Code
The Division of Weights and Measures protects consumers and businesses by promoting fairness and equity in the marketplace with the enforcement of the California Business and Professions Code and other
County laws and regulations. Areas of enforcement by the Division are:
County Weights and Measure Inspectors inspect and test weighing and measuring devices for accuracy and correctness. There are approximately 20,000 commercially used devices in San Joaquin County.
- Inspections are conducted annually on commercially used scales such as used at deli counters, flea markets, certified farmers markets, grocery stores, pharmacies, and recycling facilities. Additional scales tested are vehicle scales, livestock, and warehouse and shipping scales.
- Inspections are also conducted annually on commercially used measuring devices such as motor fuel, LPG, and water dispensers, taxi meters, odometers on ambulances and tow trucks, wire and fabric meters. Additional measuring devices tested are water, electric, and gas meters used to sub-meter to tenants at mobile home parks, apartments, and marinas.
Petroleum products sold in the county are tested to ensure minimum quality standards. Advertising price signs and labeling at gas stations, and the labeling of petroleum products sold are checked to comply with
State regulations to ensure uniformity and fairness.
County Inspectors regulate and perform audits on state-licensed weighmasters to ensure the commodity transactions based on quantities certified on a weighmaster certificate are accurate and recorded correctly. Visit the Division of Measurement Standards
site for more information.
Packages are checked to assure labeling requirement and the stated weight, measure, or count is correct. Inspectors also enforce the
Fair Packaging and Labeling Act to prevent misleading or deceptive packing or advertising. Price verifications are also conducted on scanners and point of sale systems to verify regularly-priced and sale items are correctly shelf priced. The Division also regulates firewood sales and responds to complaints. Please visit our firewood brochure
