Regardless of the changes in our federal government this year, there is one thing we know for sure: we have a new NFPA 72 2016, National Fire Alarm and Signaling Code from the National Fire Protection Association. Does that mean we should have started using the new code on Jan. 1? It depends on whether the legislature in your city or state has formally adopted a more recent building code or if your jurisdiction specifically adopted the new version. For instance, California has always adopted the most recent version of NFPA 72. If you live there, buy the new code now at http://www.nfpa.org.
