About each permit
Weighing and Measuring Device Registration
The county's Device and Point-of-Sale System Registration page says that 'Any device used to weigh or measure products or services for direct sale must be an approved type and annually registered with the County Department of Weights and Measures', naming gasoline pumps, grocery and deli counter scales and other devices. A deli, coffee shop or store selling by weight, or an auto-repair shop with fuel-dispensing meters, therefore registers each device; a business that sells nothing by weight or measure has no device to register. Under Ordinance Code §5.124.010 the permit expires December 31 and must be renewed by March 1. The figures are from §5.124.020 as amended by Ordinance 4896 (19 November 2024), which is in force; Business and Professions Code §12240 is the state authority for county device registration fees.
Point-of-Sale System Registration
The county's Device and Point-of-Sale System Registration page says that 'retail establishments that use point-of-sale (POS) systems, as defined by California law, must be registered and are routinely tested for pricing accuracy'. Ordinance Code §5.144.020 requires an annual point-of-sale system registration permit from the Agricultural Commissioner/Sealer of Weights and Measures, expiring December 31 and renewed by March 1, and §5.144.040 sets the fee by the number of checkout registers at the location: $220 for one to three, $390 for four to nine and $490 for ten or more. The same three amounts appear on the county's Weights and Measures fee sheet. Section 5.144.040 also sets a $150 reinspection fee and a 50% late fee for payment more than 60 days after the invoice. Under §5.144.050 the retailer posts the county's consumer notice at each checkout register.
