ICC just released their preliminary online voting results, and Proposal RB129-16, which attempted to remove the residential sprinkler requirement from the International Residential Code, is shown as DISAPPROVED. Therefore, the requirement to install fire sprinklers all newly constructed homes will remain in the 2018 edition of the IRC.
We were also successful in gaining approval of two changes that incentivize and support sprinkler requirements, Proposals RB89-16 and ADM36-16. However, we came up short of the required 2/3 majority to overturn committee recommendations on Proposals RB51-16 (dealing specifically with stacked duplexes), and RB69-16 (dealing with protection of lightweight floor assemblies).
