Tempe, AZ · Licensed Professional Engineering
Coordinated mechanical, electrical, and plumbing design — engineered as one system, stamped by licensed professionals, and documented for fast permit approval.
An MEP engineer in Tempe designs the systems that make a commercial building work — HVAC, electrical power and lighting, and plumbing — and seals the drawings the City of Tempe requires for a permit. Apex Grid Engineering's licensed PEs deliver that design as one coordinated system for Tempe projects: load calculations and equipment selection, power distribution and one-line diagrams, lighting and controls, and plumbing and gas piping, documented to the code edition your filing date actually falls under. Tempe design starts with 2B peak cooling, solar gain, and high-ambient equipment performance — equipment is selected and derated for desert design days, not nameplate conditions — and monsoon dust calls for maintainable outside-air filtration and protected intakes. We confirm SRP service conditions and demand-sensitive rate assumptions early, while City water and wastewater capacity and meter requirements remain parcel-specific. Because Tempe is mid-transition — the 2024 ICC codes and 2023 NEC took effect July 1, 2026, with 2018 or 2024 submittals allowed through December 31, 2026 — we lock one code path and coordinate it consistently across HVAC, electrical, plumbing, and the energy documentation, including the Solar Ready provisions in the City's adopted package. The workload is as varied as the market: research and laboratory space around Arizona State University and the Novus Innovation Corridor, technology and professional offices, biotech, multifamily, retail and hospitality build-outs, and corridor redevelopment.
Code adoptions and local amendments change on multi-year cycles. The state source verification date is 2026-07-28; we verify the governing editions with City of Tempe Community Development Department, Development Services / Building Safety at project kickoff.
Commercial applicants submit construction documents to Building Safety, then proceed through code review, permit issuance, inspections, and closeout. The decisive early step in Tempe is the code edition: the City's transition allows 2018 or 2024 submittals through December 31, 2026, so the governing edition and any project-specific submittal requirements are confirmed with Building Safety before filing, and the design is built to that single path from the start.
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.
The City of Tempe provides municipal water and wastewater service within its service area. Confirm SRP capacity, service voltage, transformer and distributed-generation requirements, plus City meter, capacity, and sewer-connection requirements, for the actual parcel before design is fixed.
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.
Reviewed 2026-09-11. Code editions and local requirements can change; confirm the current requirements with the authority having jurisdiction before design.
