Is it time to upgrade?

• Electrical service & distributionPermitted — completion not confirmedA 2024 permit specifies this work (the permit description states “(1) Main Breaker And Meter Assembly Bussing Burning Up on 400 amp 6 meter pack 1ph 120/240 Replace Meter Assembly And 2/100 amp Main breaker for apartment 1290 - Like-for-like replacement.”), but the available record does not show a final inspection. The work was permitted, but final completion is not confirmed. Official status: Inspections. TC-COM-1024-01964 — (1) Main Breaker And Meter Assembly Bussing Burning Up on 400 amp 6 meter pack 1ph 120/240 Replace Meter Assembly And 2/100 amp Main breaker for apartment 1290 - Like-for-like replacement.
• Heating, cooling & mechanicalLikely dueLast permitted 1999 (27 years ago). The assessor records cooling as WARMED AND COOLED AIR and heating as Forced Air. Packaged rooftop units work harder in Tucson than almost anywhere, so 12 to 15 years is a realistic service life rather than the 15 to 20 the industry quotes. Equipment from before about 2010 generally runs R-22, which has not been produced since 2020 — repairs mean reclaimed refrigerant at a price that often exceeds replacing the unit.

• Fire alarm & life safetyNot in this windowNothing in the permit records we read for this parcel that names this system. Any alarm or sprinkler work here predates this feed. For an occupied commercial building that is worth confirming from the panel and the inspection tags rather than assuming.
• RoofNot in this windowNothing in the permit records we read for this parcel that names this system. The assessor records the roof as Composition Shingle. Roof age matters electrically too: it sets what can be penetrated for new rooftop units, conduit, or solar.

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 — high priority

  Distribution gear this age is frequently past the point where the manufacturer still supports it. Breakers and fusible switches for obsolete lines can carry long lead times, which turns an outage into a shutdown. The permit record does not confirm this; an on-site inspection is required.

• Worth looking at

  There are 6 open code enforcement cases on this parcel. An open case can hold up a permit, and if it touches unpermitted work the electrical scope usually has to be brought up to code as part of resolving it.

• Worth confirming

  Multifamily property. House panels, unit meters, and common-area loads are usually metered and maintained separately — worth confirming which side of the meter a problem falls on before scheduling work.

• 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.

• Worth confirming

  There is an electrical reconnect permit from 2025. The service was disconnected at some point and brought back — usually after a vacancy, a utility disconnect, or work that required the power off. Worth knowing what prompted it.

• Routine

  A trade permit was pulled in 2022. 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

≈ 338,429 sq ft (county building-footprint layer, 87 structures)

Usable for solar, planning estimate

≈ 236,900 sq ft (~70% after setbacks, rooftop equipment and access paths)

Array that could fit

on the order of 2,610 kW — roughly 6,530 panels (low-tilt ballasted rows, 400 W class modules)

Estimated annual production

≈ 4,290,000 kWh (PVWatts, Tucson sun, low-tilt south)

Energy-charge offset at TEP commercial rates

$343,000–$558,000 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, “El Con Mall - Reid Park Area”, is about 3 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.

Service on record

A 2024 permit was issued; completion is not confirmed in the available record; the permit description states “(1) Main Breaker And Meter Assembly Bussing Burning Up on 400 amp 6 meter pack 1ph 120/240 Replace Meter Assembly And 2/100 amp Main breaker for apartment 1290 - Like-for-like replacement.”.

The building area, cooling and heating above come 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.
