Business License Information and Form

Hamilton Municipal Code 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 Finance Office.  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 Clerk’s Office 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.


You must contact the Finance Office 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 change above will result in the need to complete an updated license application.  This is no fee for information changes or transfer of ownership.
