The current 2016 Codes govern the construction of all building projects that have an application date of January 1, 2017 or later.  However, if your project or application was in progress before the January 1, 2017 date, the earlier 2013 Codes will still be in effect during your construction inspections and/or the plan check process. You must keep the permit current and show progress on your project. A permit is good for two years from the date of issuance and may be renewed for an additional year.  The reactivation of an expired permit will require a review for update to the new codes, depending on the progress of the construction.
