Summary
Chandler has no separate green-building ordinance; its energy-efficiency mandate is the 2024 International Energy Conservation Code, adopted by reference in Chapter 29 with local tweaks: including a locally raised maximum Energy Rating Index of 57 (up from the model code's 51) for homes in Climate Zone 2, and a RESNET third-party testing option for compliance.
The City Council of Chandler adopts by reference the International Energy Conservation Code, 2024 edition, ("IECC") ... Table R406.5 "Maximum Energy Rating Index" is hereby amended by replacing energy rating index of "51" with "57" in the climate zone 2.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 79).
Full Breakdown
12. 5 (Maximum Energy Rating Index) by "replacing energy rating index of '51' with '57' in the climate zone 2". Chandler sits in Climate Zone 2, so this locally loosens the baseline index homes must meet compared to the unamended model code. 6). 15 adds a duct-leakage test exception when ducts and air handlers sit entirely within the building's thermal envelope, avoiding a costly test requirement for compact HVAC layouts. 5) were deleted outright rather than adopted. 16.
Violations & Fines
Constructing or altering a building without meeting the adopted IECC energy standards, or without the required duct/envelope testing where no RESNET exception applies, is enforceable the same as any other Chapter 29 code violation: a Class 1 misdemeanor under Section 29-1.3(B) with fines up to $2,500 for an individual ($20,000 for an entity), up to six months imprisonment, and each day of noncompliance a separate offense.
