Is it time to upgrade?

• 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 & 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 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

  60–100 A was standard. That is enough for a mid-century house, not for a modern kitchen, HVAC, and an EV. The permit record does not confirm this; an on-site inspection is required.

• Era-based check — high priority

  Federal Pacific (Stab-Lok) and Zinsco/Sylvania panels were sold through this period. Stab-Lok breakers have a documented history of failing to trip internally; Zinsco breakers can weld to the bus so the handle moves without breaking the circuit. In both cases a replacement breaker does not resolve it — the panel itself is what gets replaced. The permit record does not confirm this; an on-site inspection is required.

• Era-based check

  Grounded branch circuits did not become the norm until the early 1960s — much of the original wiring here is likely ungrounded. The permit record does not confirm this; an on-site inspection is required.

• Era-based check

  Cloth-jacketed NM cable is common in this era. The jacket embrittles with age and heat, particularly in Tucson attics. The permit record does not confirm this; an on-site inspection is required.

Recorded sales (1)

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: 2025-01-04 (TC-RES-0125-00044) — The gas line had a small leak so a new gas line was installed by a licensed plumber. We need the permit to get the gas turned back on. When the plumber tried to apply for the permit they were informed there were other items (from 2020) that required inspection/permits. I was not the home owner at that time, I purchased the home at the end of 2023. I went to your office down town and they weren't able to tell me how to correct the previous code violations. They also couldn't tell me what exactly the violations were so I'm not aware how to correct the items below. -Electrical Panel -HVAC Unit I'm looking to have an inspection completed so I know how to correct all items so I can get my gas turned back on. I currently don't have access to heat or hot water in my home..

Permit history (7)

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 (3)

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.
