Tempe's local amendment package applies to the adopted codes, and the City's green-building guidance confirms Solar Ready provisions in the IECC. The same guidance describes EV-ready provisions as being pursued rather than confirming them as a universal adopted requirement; verify the ordinance and project-specific amendments with Building Safety.

Tempe has a substantial commercial base tied to Arizona State University and its research and innovation ecosystem, the Novus Innovation Corridor, technology and professional offices, biotech and advanced services, multifamily, retail, hospitality, and corridor redevelopment. These sectors create varied MEP, energy, tenant-improvement, and site-engineering demand.

Tempe Engineering FAQs

Which code edition applies to a Tempe commercial project?
Tempe's official notice adopts the 2024 ICC codes and 2023 NEC effective July 1, 2026, while allowing 2018 or 2024 submittals during the transition through December 31, 2026. Confirm the permitted path and filing date with Building Safety before design is locked.
Who provides electric, water, and sewer service in Tempe?
SRP is the electric utility, and the City of Tempe provides municipal water and wastewater in its service area. Service territory, capacity, meter, transformer, interconnection, and connection requirements must be confirmed for the individual parcel.
What site conditions should a Tempe project investigate?
Peak heat, solar gain, and monsoon dust affect building systems; drainage, floodplain and wash exposure, soils, and utility corridors affect site design. Check FEMA maps, City criteria, and the project geotechnical report rather than applying a citywide assumption.

Commercial applicants submit construction documents through the City's permitting and plan-review process, then proceed through code review, permit issuance, inspections, and closeout. The applicable code path and any project-specific submittal requirements should be confirmed with Building Safety before filing; an online portal name, review SLA, and self-certification eligibility were not verified.
