A screening report for electrical planning, assembled from public-record indicators. It is not an official record and every figure in it should be verified against the issuing agency before it is relied on.

• Electrical service & distributionNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2026 special events fire permit - vendor permit is on file (and 2 more like it) — work like this is often folded into a larger permit without being named, so open that record and check its scope before concluding anything. No permitted service or distribution work shows in the record we read. Gear of this era is generally still supported, but spare capacity drifts with every tenant improvement — worth a load check against the panel schedule before adding major equipment. Separately from replacement: NFPA 70E expects the arc-flash study to be reviewed at least every five years, or after any change to the service.
• Heating, cooling & mechanicalPermitted — completion not confirmedA 2023 permit specifies this work (the permit description states “Replacing 24 like for like HVAC package units on roof”), but the available record does not show a final inspection. The work was permitted, but final completion is not confirmed. Official status: Issued. TC-COM-1123-02648 — Replacing 24 like for like HVAC package units on roof
• Fire alarm & life safetyFinaled permit foundA newer 2023 permit for the same system is recorded as “Expired” — The permit expired without a confirmed final status. The permit description states “Minor adjustments to existing in rack sprinklers to accommodate new racking layout.”. Last permitted 2021 (5 years ago). Panels and devices age out on their own schedule, and the code moves underneath them — a system that was compliant when installed is not automatically compliant now. T21FC00479 — FIRE ALARM UPGRADE
• RoofPermitted — completion not confirmedA 2026 permit specifies this work (the permit description states “Main Roof: Leave the existing roofing system in place. Temporarily, by section, move over and stockpile the rock ballast, then install a new loose-laid TPO membrane with heat-welded seams. After each section of TPO installation, replace the rock ballast over the new membrane. The contractor’s canopy and garden center roofs are mechanically attached TPO systems (unlike the main ballasted roof) and currently have two layers of membrane. In these areas, both existing membrane layers will be removed and replaced with a new TPO membrane. The existing insulation may remain in place, provided it is confirmed to be dry.”), but the available record does not show a final inspection. The work was permitted, but final completion is not confirmed. Official status: Issued. TC-COM-0726-01044 — Main Roof: Leave the existing roofing system in place. Temporarily, by section, move over and stockpile the rock ballast, then install a new loose-laid TPO membrane with heat-welded seams. After each section of TPO installation, replace the rock ballast over the new membrane. The contractor’s canopy and garden center roofs are mechanically attached TPO systems (unlike the main ballasted roof) and currently have two layers of membrane. In these areas, both existing membrane layers will be removed and replaced with a new TPO membrane. The existing insulation may remain in place, provided it is confirmed to be dry.

A found permit means a lot. A missing one means less. We read the City of Tucson’s own permit file, not a recent extract of it — back to about 2006, and into the 1990s on properties with that much history. Microfiche before then was never fully digitized. Every record links to the city’s official file. A blank line does not say nothing was done: work gets done without permits all the time. The only way to know what is actually installed is to look at it.

What that usually means electrically

• Era-based check

  Gear in this age range is usually still supported but is due for infrared scanning and torque verification if that has not been done recently. The permit record does not confirm this; an on-site inspection is required.

• Era-based check

  NFPA 70E expects arc-flash studies to be reviewed at least every five years, or after any change to the service. Buildings this age often have labeling that no longer matches the installed gear. The permit record does not confirm this; an on-site inspection is required.

• Routine

  A trade permit was pulled in 2017. Trade permits cover electrical, plumbing, and mechanical work individually, so some permitted trade work has been done here since.

Solar and energy potential

Roof footprint

≈ 208,703 sq ft (county building-footprint layer)

Usable for solar, planning estimate

≈ 146,100 sq ft (~70% after setbacks, rooftop equipment and access paths)

Array that could fit

on the order of 1,610 kW — roughly 4,030 panels (low-tilt ballasted rows, 400 W class modules)

Estimated annual production

≈ 2,650,000 kWh (PVWatts, Tucson sun, low-tilt south)

Energy-charge offset at TEP commercial rates

$212,000–$345,000 a year (8–13¢/kWh energy + power-supply charges, by season and rate class)

Planning-level arithmetic on the roof area above — not a shading study, a structural review or a design. The offset assumes the building uses the power as it is generated; TEP pays far less (its export rate is about 5¢/kWh) for surplus sent to the grid, so the load profile decides the real value. The 30% federal credit (§48E) still applies to commercial systems placed in service by the end of 2027 — projects that began construction by July 4, 2026 have longer; confirm timing with a tax adviser.

TEP grid capacityThis parcel is not inside any of the 11 areas TEP has mapped as saturated with distributed generation (the nearest, “I-10 and Valencia Rd”, is about 5.6 miles away — TEP’s map set, July 2020). New generation still goes through TEP’s interconnection screens, and a heavy new load still merits a utility capacity check — the maps only mark where that review is most likely to bite.

The building area above comes from the Pima County Assessor’s record, as we read it on 28 Jan 2026. Each other row names its own source.

The most recent permitted work on this parcel was in 2026. That says the parcel was worked on under permit, not what the work covered — a roof, a pool or a changeout tells you nothing about the electrical service. Work done without a permit leaves no trace here at all.

This is an inference from public records — the year a structure was built, how it is classified, and what has been permitted. It is not an inspection, and nothing here confirms what is actually installed at this address. The only way to know is to look in the panel. See an error in this public-record report?

Utility and upgrade pathElectric service here is Tucson Electric Power (TEP). A service or panel upgrade needs a TEP meter release and has to meet TEP’s service requirements — meter height and location, clearances, and the point of attachment. See TEP new-service requirements and the TEP standards notes.

The contractor’s read is a plain-English brief of the record above, written by AI — what it shows across electrical, mechanical and the building itself, what is missing for the era, and what to verify on site.

What the flood note is not. The FEMA map linked above is the National Flood Hazard Layer — the federal insurance map. Local floodplain mapping is not reproduced here; use the authority’s own map, linked above. Nothing here is a floodplain determination, an elevation certificate, or a substitute for one. A parcel can straddle a boundary, and a Letter of Map Amendment can remove a structure the map still covers. For a determination, ask the floodplain administrator for the jurisdiction named above; for a design that has to satisfy one, that is work we do.
