Business License Information and Form

Hamilton Municipal Code (Chapter 5.04 Business Licenses) requires businesses operating within the Hamilton City limits, except for those specifically exempt by state law, to obtain a Hamilton City Business License. 

To obtain a City Business License, application must be made to the Public Works Department.  Applications are subject to approval by various city or county inspectors depending on the nature of your business.  Upon approval, the City Finance Office will collect the license fee and issue a license.  The license must be posted for the public to see.

The license is good for one year from January to December.   Courtesy renewal notices are mailed to business owners prior to the expiration date on license.  Licenses may be renewed in person at the City's Public Works Department, located at 920 New York Avenure, or by mail within 30 days to avoid a penalty.   Failure to obtain a Business License will result in the issuance of a citation which will result in a fine. Click Here to download the current City of Hamilton Business License Registration Form.

You must contact the Public Works Department if any change occurs. 

 Changes may include, but not limited to:

  •     Change of physical address
  •     Change of mailing address
  •     Change of ownership
  •     Change in nature of business
 Any of the above changes will result in the need to complete an updated license application. 

There is no fee for information changes or transfer of ownership.
