Business License

We Welcome Your Business to the City of Ontario!

A business license is required prior to commencing business in the City. 

A new application is also required when changing locations or a change of ownership occurs. You can submit your application using an online application. Please see the Getting Started section for more information.

The City's Business Licensing staff is also available to provide you with assistance or answer any questions you may have about obtaining or renewing a business license. We thank you for choosing the City of Ontario and hope that you will be successful in your business endeavors.

The City of Ontario has an agreement with Hinderliter de Llamas and Associates (HdL) to help with business license processing, collections, and compliance.
