• Electrical service & panelNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2013 addition (house expansion, garages, detached structures, sheds, porches, etc.) 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. That does not tell you the service is original — only that nothing has been permitted here recently. The build year is the better clue, and it is above.
• Heating & coolingNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2013 addition (house expansion, garages, detached structures, sheds, porches, etc.) 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. 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 Tile.
• Plumbing work on recordNot in this windowNothing in the permit records we read for this parcel that names this system. Unremarkable — plenty of buildings never need a permitted plumbing repair.

A found permit means a lot. A missing one means less. This parcel is in the Town of Oro Valley, so we read the town’s own SmartGov permit portal alongside the regional records. Every town record links to its 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.

Most recent permit on record for this parcel: 2013-05-03 (MB1300300).

Permit history (2)

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 issuing office’s official file — the Town of Oro Valley’s portal for town permits. 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.
