• Electrical service & panelNot in this windowNothing in the permit records we read for this parcel that names this system. 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 & coolingPermitted — completion not confirmedA 2022 permit specifies this work (the permit description states “NEW ELECTRICAL OUTLETS AND SUBPANEL, NEW MINI SPLIT T22DV03832”), but the available record does not show a final inspection. The work was permitted, but final completion is not confirmed. Official status: Issued. City inspection record: COT - RSEL - Electrical Final approved 2023-01-05. The assessor records cooling as Refrigeration and heating as Forced Air. T22CM07442 — NEW ELECTRICAL OUTLETS AND SUBPANEL, NEW MINI SPLIT T22DV03832
• 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 recordPermitted — completion not confirmedA 2017 permit specifies this work (the permit description states “SEWER REHABILITATION - NO EXCAVATION NOTE: 700 N CAMPBELL AVE WAS REQUESTED - THAT IS NOT A VALID ADDRESS”), but the available record does not show a final inspection. The permit expired without a confirmed final status. Official status: Expired. T17RW05075 — SEWER REHABILITATION - NO EXCAVATION NOTE: 700 N CAMPBELL AVE WAS REQUESTED - THAT IS NOT A VALID ADDRESS

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

  Knob-and-tube wiring may still be present in original, un-remodeled areas. It has no ground and is not rated for modern loads or insulation contact. The permit record does not confirm this; an on-site inspection is required.

• Era-based check — high priority

  Original services this age were 30–60 A fuse panels. Nearly every one still in place is undersized for a modern household. The permit record does not confirm this; an on-site inspection is required.

• Era-based check — high priority

  Branch circuits from this era are typically ungrounded two-wire — the reason you see two-prong outlets or ungrounded three-prong replacements. The permit record does not confirm this; an on-site inspection is required.

• Worth confirming

  The assessor records a pool on this parcel. Equipment bonding, the equipotential bonding grid and GFCI protection on the pump and light circuits are the usual findings on pool equipment — the pool-bonding rules in NEC Article 680 were expanded in the 2008 cycle, so a pool built before that is worth an on-site check.

Permit history (9)

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 (6)

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.
