Permit Office (AHJ)
City of Tucson Planning & Development Services Department (PDSD)
Pima County · Arizona
MEP, structural, civil, and energy-compliance engineering for Tucson projects — permitted through City of Tucson Planning & Development Services Department (PDSD) and designed to the city's adopted codes and amendments.
Coordinated mechanical, electrical, and plumbing design — engineered as one system, stamped by licensed professionals, and documented for fast permit approval.
Structural systems designed to the loads your state actually imposes — gravity, seismic, wind, and snow — with drawings built to get approved the first time.
Site engineering that clears local review — grading, drainage, and utilities designed to each jurisdiction's published standards from day one.
Energy compliance handled as engineering, not paperwork — documentation matched to the exact code edition your permitting jurisdiction enforces.
Tucson is unusual for the Tucson-Pima County Outdoor Lighting Code, one of the strictest dark-sky ordinances in the country, which limits exterior lumens, shielding, and color temperature to protect nearby astronomical observatories. The city also enforces water-harvesting and commercial rainwater/greywater provisions that shape site and plumbing design beyond the base IPC.
Tucson's construction market is anchored by the University of Arizona, Raytheon/RTX defense and aerospace manufacturing, Davis-Monthan Air Force Base, healthcare, and a growing logistics and semiconductor-adjacent industrial base along the I-10 corridor. Demand for lab, cleanroom, and advanced-manufacturing space keeps MEP and structural work steady.
Reviewed 2026-09-11. Code editions and local requirements can change; confirm the current requirements with the authority having jurisdiction before design.
Plan review runs through Tucson's online permitting portal (TDC Online / Accela), and PDSD publishes review-cycle timelines by project type with a paid expedited option for eligible commercial work. Larger sites often need concurrent review of zoning, engineering, and building packages, so early pre-submittal meetings with PDSD help sequence the reviews and avoid resubmittal loops.
