Is it time to upgrade?

• Electrical service & distributionNot in this windowNothing in the permit records we read for this parcel that names this system. No permitted service work shows in the record we read. That is not evidence the gear is original or current — only that nothing recent required a permit here. Capacity and condition come from the nameplates and the panel schedule, not from this record. 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 & mechanicalNot in this windowNothing in the permit records we read for this parcel that names this system. 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. Worth confirming from the equipment nameplate rather than the record. Replacing a rooftop unit is also an electrical question: the new unit's minimum circuit ampacity and its disconnect often differ from the old one.
• 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. 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. This parcel is in unincorporated Pima County, whose building permits are issued by Pima County Development Services and are not part of this record — what is shown here comes from the regional records, and is likely incomplete for this address. A records request to the county is the authoritative check. 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

• Worth confirming

  Industrial and warehouse space usually means three-phase motor loads. High-bay LED retrofits and added VFDs both change the load picture.

Solar and energy potential

Roof footprint

≈ 8,252 sq ft (county building-footprint layer; capped at the parcel’s land area — a mapped structure crosses the lot line)

Usable for solar, planning estimate

≈ 5,800 sq ft (~70% after setbacks, rooftop equipment and access paths)

Array that could fit

on the order of 65 kW — roughly 160 panels (low-tilt ballasted rows, 400 W class modules)

Estimated annual production

≈ 110,000 kWh (PVWatts, Tucson sun, low-tilt south)

Energy-charge offset at TEP commercial rates

$9,000–$14,000 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 capacity — mapped saturation areaThis property sits within about half a mile of “I-10 and Valencia Rd”, one of 11 areas TEP has mapped as saturated with distributed generation (customer solar) relative to circuit capacity. On a saturated circuit, new solar or battery systems can trigger supplemental utility review before interconnection is approved — and a large new load such as DC fast charging or process equipment is worth a capacity conversation with TEP before a site plan hardens. The boundary here is approximate, digitized from TEP’s map of the area (PDF, July 2020); TEP’s own interconnection screening is the authority, and circuit status can have changed since the maps were published.

Nothing on record for this parcel or street in Pima County's online permit system. The county's older records were only partially moved online, so this is meaningful for recent decades and weak evidence about anything older — and plenty of work is never permitted 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 out here is split: Trico Electric Cooperative serves much of unincorporated Pima County, Tucson Electric Power serves the rest, and a few areas sit on other systems. The meter release, clearances and point of attachment for an upgrade come from whichever utility serves the meter — check a recent bill or the meter label. See TEP new-service requirements for the TEP side.

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 flood zone shown is FEMA’s 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.
