• 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 & coolingLikely dueLast permitted 2004 (22 years ago). City inspection record: MECHANICAL - FINAL approved 2004-12-20. Contractor of record: FIRST AIRCONDITIONING SERVICE CO *C. 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. Equipment from before about 2010 generally runs R-22, which has not been produced since 2020 — repairs mean reclaimed refrigerant at a price that often exceeds replacing the unit.

• 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 Asphalt.
• 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. 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

  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.

Recorded sales (2)

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.

Most recent permit on record for this parcel: 2022-04-06 (T22RW01325) — 2 5x5 bellholes in dirt front / blacktop for SWG crews to repair gas leak@5LF.

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.

Code enforcement (1)

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?
