Service on record

City records show the 2023 permit was finalized; the permit description states “WO T69869. TEP WORKING ON EXISTING POLE IN ROW (RED CIRCLE), EXTENDING SECONDARY WIRE (GREEN LINE), AND INSTALLING POLE IN CUSTOMERS PROPERTY (YELLOW CIRCLE) TO ASSIST WITH SERVICE UPGRADE” — an increase in capacity as described, not a confirmed installed rating.

Is it time to upgrade?

• Electrical service & distributionCurrentA newer 2023 permit for the same system is recorded as “Issued” — The work was permitted, but final completion is not confirmed. The permit description states “Upgrade electrical service to 400amps”. Last permitted 2023 (3 years ago). City inspection record: TRSP - ROW - Final/Close-Out approved 2023-07-31. Applicant on the permit: Desert Barricades LLC. The permit describes an increase in capacity, which is the single best sign the electrical has actually been brought forward. 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. TR-UTL-0323-01079 — WO T69869. TEP WORKING ON EXISTING POLE IN ROW (RED CIRCLE), EXTENDING SECONDARY WIRE (GREEN LINE), AND INSTALLING POLE IN CUSTOMERS PROPERTY (YELLOW CIRCLE) TO ASSIST WITH SERVICE UPGRADE
• 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. 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

• Worth confirming

  A pool or spa was permitted in 2021. Pool equipment brings its own bonding grid, GFCI requirements, and usually a subpanel — and the bonding rules have tightened since, so older installations are worth verifying.

• Era-based check

  A capacity and condition review is the usual starting point before any tenant improvement or added load. The permit record does not confirm this; an on-site inspection is required.

Most recent permit on record for this parcel: 2023-06-13 (TC-COM-0623-01489) — Upgrade electrical service to 400amps.

Permit history (13)

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 (4)

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.
