Is it time to upgrade?

  • Electrical service & distributionGetting onLast permitted 1997 (29 years ago). Contractor of record: GAMBLE ELECTRIC INC ,. 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. T97EL00121 — ELEC NEW SERVICE
  • Heating, cooling & mechanicalNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2026 fire operational 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. 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 2018 (8 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. T18FC00247 — Relocate 3 uprights & 31 pendants
  • 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 — 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.

  • 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.

  • Worth confirming

    A pool or spa was permitted in 2022. 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.

  • Worth confirming

    There is an electrical reconnect permit from 2017. 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.

Recorded sales are the sales the Pima County Assessor has on file from affidavits of property value — not every transfer, not listings, and not a valuation. Parties are never shown here. A sale with no permitted electrical work since is worth knowing before the next sale or a remodel.

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 (5)

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.

This is an inference from public records — the year a structure was built, how it is classified, and what has been permitted.

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.

How this report was built

This is a reading of public records for parcel 11516023B — 62 permits on file from 1997 to 2026 (17 combo, 7 spklr, 5 fireoper, 4 fire operational) and 5 code enforcement cases — assembled from the Pima County parcel file, the City of Tucson’s Property Research Online file (permits back to about 2006, further on some parcels), and the City’s GIS permit and code-enforcement layers (2022 onward). Public records last checked 2026-08-17; the record is re-read at least weekly. Each permit and code case links to its official file. The verdicts are inferences from what was permitted and when, and from the era the building went up; they are not an inspection, and nothing here confirms what is installed. A permit that is present is strong evidence; a permit that is absent is weak evidence — plenty of work is never permitted, and older county records were only partly moved online.
