Gwinnett County mailed its property assessments last week.

Heads up, Gwinnett: Your property assessments are in the mail.

And it’s quite possible you’ll see an increase in your home’s value.

Stewart Oliver, Gwinnett’s chief appraiser, said about 63 percent of the county’s residential properties will see a change in value on this year’s assessments. The average change in those properties was an increase of about 12 percent.

That’s compared to about 24 percent in 2016.

“It’s not necessarily that it’s changed that much since last year,” Oliver said. “It’s changed that much since we last renewed that value.”

Including both residential and commercial properties, the county mailed about 277,000 assessment notices on Friday. The overall tax digest was up about 7 percent, Oliver said.

Overall property values were up about 9 percent in 2016; 3 percent in 2015; and 10 percent in 2014.

Oliver stressed that the assessments mailed Friday are not tax bills. Those are created later using the property assessment and the 2016 millage rates set by Gwinnett’s Board of Commissioners and school board, as well as individual cities where applicable.

Property assessments can be appealed, however.

Appeals must be filed within 45 days of the date on the notice of assessment and can be completed online at Property owners can also contact the tax assessor's office by calling 770-822-7200 or sending an email to
