Building Energy Code

The Rhode Island Building Code Standards Committee adopts, promulgates and administers the state building code. Compliance is determined through the building permit and inspection process by local building code officials and the State Building Commission. The local code official enforces the state building code. The State Building Commissioner enforces the code for all state buildings and buildings built on state-owned property.

2018 IECC and ASHRAE 90.1-2016 are the current standard for building codes in the State. The code was voted and appoved with minor amendments on a public hearing on February 1, 2022.


HB 5986, signed in May 2009, directed the Rhode Island State Building Commission to update the state building code to include the 2009 IECC and ASHRAE 90.1-2007 and to develop a plan to achieve compliance in 90 percent of new and renovated building space by February 2017. The new codes went before the State Legislature's Legislative Oversight Committee for final approval in early 2010. After a period for training of code officials and other stakeholders, the 2009 edition of the State Energy Conservation Code took effect July 1, 2010.
