Is it time to upgrade?

• Electrical service & distributionCurrentLast permitted 2024 (2 years ago). City inspection record: COT - LCEL - Electrical Final approved 2024-11-15. Worth reading the permit itself: it names the service but does not read as an increase in capacity, so this may have been a like-for-like replacement rather than an upgrade. 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. TC-COM-0824-01697 — Electrical Service: Replacement of existing and some Install new overhead warehouse lighting
• Heating, cooling & mechanicalNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2016 build permit is on file (and 1 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. 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 safetyCurrentLast permitted 2016 (10 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. T16BU00536 — SPRINKLER
• 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. 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 digitised. 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.

• Worth confirming

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

Permit history (20)

How to read the status column: Final / Complete / C of O — city records show the permit was finalized. Issued — the work was permitted, but final completion is not confirmed. Applied / In review / Approved / Fees paid — proposed, not completion. Expired — the permit expired without a confirmed final status. Void / Withdrawn / Canceled — not evidence the work was installed. Any other status is shown exactly as the issuing office records it, without a completion reading.

Code enforcement (2)

Code cases and housing-code violations recorded against this parcel, by category. Closed cases stay on the record, and most of these are closed — check the status column. We show the category and the official record number rather than the complaint text, which often names people who have nothing to do with the property.

Record numbers link to the City of Tucson’s official file. Highlighted rows are the ones that imply electrical work or an unpermitted-work finding.

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?

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.
