Contact our Department

Due to significant public health concerns from the COVID-19 coronavirus and the need to meet social distancing requirements, the Department of Agriculture/Weights and Measures' offices are currently operating under modified schedules. 

All three of our offices are staffed and have partially re-opened to serve our customers. However, customers are strongly encouraged to call ahead and make appointments for any necessary services. 

Please see the July 2020 Department of Agriculture / Weights and Measures Update for more information on current office hours.
