Gwinnett County wants residents to know that commercial property value assessment notices mailed on March 25 should be disregarded because of an error by the vendor.

Corrected notices were sent out Wednesday. Because of the error, the last day to appeal commercial assessment values will be May 23.

Commercial property owners who want to view the assessment notice before receiving it by mail should visit. http://www.gwinnettcounty.com/TRRPWeb/EntryPoint.do.
