In an effort to proactively inform customers, and give them time to prepare for important building code changes announced by the Department of Land Use, the Code Official will allow a three (3) month transition period for implementation of these codes from the date of adoption to May 31, 2015.  During this transition period, the County will accept projects designed to either the old codes or the new codes.  Submittals are not allowed to mix and match code provisions, and must identify which code edition is used for the design of the project.

All projects submitted on or after June 1, 2015 will be reviewed using the new regulations.  To receive additional extension between June 1, 2015 and August 31, 2015, the contractor or design professional must request the extension in writing and demonstrate the hardship for transitioning to the 2015 codes.
