NEC in Effect - 4/1/2017

The 2017 edition of the National Electrical Code® (NEC®) was issued by the NFPA Standards Council on August 4, 2016. The effective date, which is the date that it replaces the prior (2014 edition) in the NFPA family of codes and standards, was August 24, 2013. As of that date, the 2017 NEC became officially available for adoption by federal, state, county, and municipal governmental entities.

As of January 1, 2017, the 2017 NEC is in effect in one state, the 2014 NEC is in effect in 35 states, the 2011 NEC is in effect in five states and the 2008 NEC is in effect in six states. If you have a question on the status of NEC adoption in any state, please contact your NFPA Regional Electrical Code Specialist for that region of the U.S.

NEC adoption process in progress

As of January 1, 2017 the 2017 NEC is effective in one state (Massachusetts) and 25 other states have completed or are in the process of updating the statute or administrative rule through which the NEC is adopted to reference the 2017 edition. There are five states currently in the process of adopting the 2014 NEC.

This table provides the current status of NEC adoption in those states having a statewide adoption that impacts construction, trade licensing or both. For those states there is a hyperlink to the board or agency responsible for promulgating the NEC.
