How inspections work

Inspections usually include identification of device type, verification of device certification (seal), field testing with known standards, and issuance of a report or tag. If a device fails, the inspector will note corrective actions and may set deadlines for repair or replacement. Reinspections often incur fees set by the county.

  • Scheduling: contact the county sealer to book an inspection and confirm any prep requirements.
  • During inspection: inspector checks calibration, seals, and accuracy against standards.
  • After inspection: you receive a report; failed devices may be tagged out until corrected.
Keep maintenance and calibration records available before inspection to speed the process.

Common violations and typical penalties

  • Unsealed or uncertified commercial scales — remedy and possible fines or repair orders.
  • Inaccurate fuel dispensers — may result in corrective orders and civil penalties.
  • Tampered or altered measuring devices — potential seizure and stronger enforcement actions.

Action steps

  • Contact the Stanislaus County sealer to schedule testing and confirm fees and preparation.
  • Pay any required inspection or reinspection fees as directed by county procedures.
