Code Changes Around the Nation

Tennessee

According to Wendy Smith, marketing & public relations manager for the Town of Farragut, the state anticipates the adoption of all the I-Codes late summer. While Tennessee municipalities have seven years to adopt the most recently published edition of the code, two jurisdictions decided they didn’t want to wait.

Farragut and Knoxville, two sizable communities located slightly northwest of the Great Smoky Mountains, boast a combined population of nearly 200,000. Farragut decided to adopt the 2018 IBC in mid-April, and the Board of Mayor and Aldermen also approved adoption of the 2018 International Residential, Mechanical, Plumbing, Fuel Gas, Energy Conservation, Property Maintenance, Swimming Pool and Spa, and Existing Building Codes for later this year.

All of the aforementioned codes went into effect in Farragut on August 5. Knoxville has already adopted the 2018 suite of I-codes.

Flagstaff, Ariz.

In mid-June, the Flagstaff City Council adopted a host of 2018 I-codes, including the IRC and IECC. The city had been operating under the 2009 IECC (with weakening amendments) since 2013.

Within the IRC, they adopted the Appendices on tiny houses and solar-ready provisions for detached one- and two-family dwellings and townhouses. The City also set the maximum flow rate on water closets to 1.3 gpf, 1 pint per flush for urinals, and an effective flush volume of 1.28 gpf for dual-flush water closets. The City also added electric vehicle (EV) charging infrastructure requirements for commercial, multi-family and single-family buildings in the city.

Illinois

HB 2652 passed through the General Assembly in mid-May, was sent to the Governor in mid-June and signed into law in late July. The legislation allows for electric vehicle and solar ready appendices to be adopted in the building code, if approved by the Capital Development Board.8 Prior to HB 2652, published supplements to the code were prohibited.

Indiana

In early July, the Indiana Fire Prevention and Building Safety Commission issued a Notice of Intent to adopt the 2018 IRC with statewide amendments. This draws a very lengthy process to a close, though the state is notoriously slow in updating their energy code. The amendments, which include an ACH rate of 5 (instead of the model code’s 3), will make this code less efficient than its namesake. The new code went into effect August 1.
