Is it time to upgrade?
- Electrical service & distributionNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2023 fire construction 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. That does not mean the gear is original — only that nothing has been permitted here recently. Where it matters is capacity: obsolete distribution lines carry breaker and fusible-switch lead times that turn an outage into a shutdown, and that is worth knowing before a new tenant or a new rooftop unit. 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. Worth knowing: a 2023 fire construction 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 2023 (3 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. TF-FCP-1223-01400 — Replace obsolete EST2 panel with new EST4. 1 Panel 1 annunciator
- 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
A pool or spa was permitted in 2023. 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.
- Routine
Office and medical tenant improvements are usually limited by available panel spaces and branch circuit capacity, not by the service itself.

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.
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.
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 14029050B — 20 permits on file from 2006 to 2023 (5 row, 4 spklr, 3 zoning verification letter, 3 pool / spa) — 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 2026-08-16; 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.
