Effective July 1, 2017, there is a 60 day renewal window. A person wishing to renew a Permit to Carry Weapons
must apply within 30 days before the permit expires, or within 30 days after the permit expires, otherwise the higher NEW
permit fee must be charged. Please note that while a permit can be renewed within 30 days after it expires, a person
whose permit has expired should not go armed in a fashion that requires a permit until a person has renewed their permit.
A person who holds (or held) a permit issued on or after 1/1/2011 is not required to complete another
training course to renew or obtain a new permit to carry weapons, however, please note that even though re-training is
not required, completing another training course.
