Significant Changes to the 2007 Florida Residential Code Chapters 1 thru 3 First Coast Chapter/BOAF. Learning Objectives.
The attendees will obtain the information on the Florida Specific Code Changes and perhaps more importantly be aware of the base code changes found in the 2006 IRC from the 2003 IRC that Florida does not identify as a change.
Every effort has been made to identify all changes found in the 2007 Florida Building Code-Residential.
However, not all may have been identified, and it is up to the user to become familiar with the code sections that they are using.

Vertical lines in the margins within the body of the code indicate a change from the requirements of the base codes to the 2007
Florida Building Code effective March 1, 2009.
