2009 New Jersey Uniform Construction Code (NJAC 5.23-3)


On September 7, 2010, a New Jersey Department of Community Affairs final rule adopting new state building codes was published in the New Jersey Register (42 N.J.R. 2043a) and became effective. This was nearly one year to the day after DCA initially proposed the rule (41 NJR 3140a) in September 2009.

The energy subcode of the New Jersey Uniform Construction Code (NJAC 5.23-3) has been amended to incorporate the 2009 IECC and ASHRAE Standard 90.1-2007 (in lieu of Chapter 5 of the IECC). There will be a six-month transition period during which builders may use the new construction codes edition or the previous one. The implementation of duct testing requirements will be delayed until January 2013.

This rule had been set to become effective on February 1, 2010, but on January 20, newly-inaugurated Gov. Chris Christie signed Executive Order 1, freezing the implementation of all proposed rules for 90 days pending review by the new administration. Further delays stalled the update from the previous state energy code based on the 2006 IECC and Standard 90.1-2004.
