Arizona – Commercial IgCC Green Construction Code
City of Scottsdale
City of Phoenix
Kayenta Township (Tribal Community)

The first model code focused on new and existing commercial buildings addressing affordable green building design and performance. The IgCC provides the building industry with language that both broadens and strengthens building codes in a way that will accelerate the construction of high performance, green buildings. It provides a vehicle for jurisdictions to regulate green for the design and performance of new and renovated buildings in a manner that is integrated with existing codes, allowing buildings to reap the rewards of improved design and construction practices. Includes ANSI/ASHRAE/USGBC/IES Standard 189.1-2014 for the Design of High Performance Green Buildings Except Low-Rise Residential Buildings as an alternative path of compliance.
The current adoption of the IgCC addresses the following topics:
- General Scope/Compliance – Jurisdictional Requirements and Project Electives (Chapter 1)
- Site/Land Development (Chapter 5)
- Water Conservation (Chapter 6)
- Energy Conservation (Chapter 7)
- Indoor-Air and Environmental Quality (Chapter 8)
- Materials and Resources Conservation (Chapter 9)
- Construction and Plans for Operation (Chapter 10)
It is important to note that the 2018 IgCC does not apply to the following structures or building uses as identified in the wording of the code in sub-section 101.3.2(2.2)
- Single-family dwellings
- Multi-family dwelling of three stories or fewer above grade
- Manufactured houses (mobile homes)
- Manufactured houses (modular)
- Building projects that use none of the following:
- Electricity
- Fossil fuels
- Water
- New buildings and their systems
- New portions of buildings and their systems
- New systems and equipment in existing buildings, and relocated existing buildings and temporary structures as specified by the code
The intent of the IgCC is to establish green construction minimum regulations for all new construction other than single-family residential that addresses buildings, systems and theirs sites while utilizing prescriptive and performance-based options for compliance.
