• Electrical service & panelPermitted — completion not confirmedA 2006 permit specifies this work (the permit description states “ELEC: UPGRADE TO 200 AMP (APA)”), but the available record does not show a final inspection. The permit expired without a confirmed final status. Official status: Expired. City inspection record: last recorded inspection 2006-05-11; no approved final is shown. T06EL00860 — ELEC: UPGRADE TO 200 AMP (APA)
• Heating & coolingNot in this windowNothing in the permit records we read for this parcel that names this system. The assessor records cooling as Refrigeration and heating as Forced Air. Cooling equipment works 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.
• Water heaterNot in this windowNothing in the permit records we read for this parcel that names this system. Water heaters are frequently swapped without a permit, so this line is especially weak evidence either way.
• RoofNot in this windowNothing in the permit records we read for this parcel that names this system. The assessor records the roof as Prepared Roll.
• Plumbing work on recordOn recordLast permitted 2006 (20 years ago). Plumbing permits cover everything from a full re-pipe to a few feet of sewer repair, so this is a record that work happened rather than a statement about the whole system. T06PL00808 — INSTALL: NEW SEWER LINE

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

  Federal Pacific Stab-Lok and Zinsco/Sylvania panels were still being installed into the 1980s. Both have documented failure-to-trip histories, by different routes: Stab-Lok breakers fail internally — the trip mechanism jams or sits out of calibration — while Zinsco breakers can weld to the bus, so the handle moves but the circuit stays live. Neither is fixed by a replacement breaker, which is why the panel is what gets replaced. The permit record does not confirm this; an on-site inspection is required.

• Era-based check

  100–150 A was typical. Workable for the original house, tight once you add EV charging or electric heat. The permit record does not confirm this; an on-site inspection is required.

Recorded sales (4)

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.

Permit history (10)

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. See an error in this public-record report?
