Permit authority Adopted codes Local amendments Utilities Climate Market context

Local Engineering Context

Authority Having Jurisdiction: City of Phoenix Planning & Development Department (SHAPE PHX)
Building Code: 2018 IBC / 2017 NEC with Phoenix amendments
Energy Code: 2018 IECC with Phoenix amendments
Local Market: The APS/SRP territory boundary runs through the Phoenix metro — the serving utility affects rate structures, demand charges, and interconnection timelines, so we confirm the utility at schematic design.
Climate & Engineering Conditions: ASHRAE climate zone 2B; high cooling loads translate to large electrical service demands; solar PV penetration is high, and EV charging is increasingly required on new commercial construction.
