Weights & Measures
Recently, the Napa County Department of Weights & Measures has updated our fee structure. Many of the fees administered for Weights and Measures device registration are set by legislation within the California Business and Professions Code (CA B&P), which establishes a maximum amount that can be charged. We spent some time updating our fees and ordinances, including our Price Verification Program which began in 2007 and is now seeing its first fee increase. This has been a very successful program to monitor and maintain pricing accuracy for the consumers and businesses of Napa Valley.
In July, our office will be sending out invoices for device and point of sale system registration which will encompass a six month period, including July through December. This is a result of our efforts to go to a calendar year billing cycle beginning in January 2020. The change is an effort to align with other department registrations, permits, and fees, in addition to aligning with our inspection work which is based on a calendar year.
If you have any questions, please contact the Napa County Weights & Measures Department.
The Napa County Department of Weights and Measures is divided into several programs to:
- Ensure the accuracy of commercial weighing and measuring devices
- Verify the price, quantity and labeling of packaged and bulk commodities
- Verify quality, advertising and labeling standards for various petroleum products
- Enforce Weighmaster laws to assure accuracy of information on Weighmaster certificates.
