Service on record

City records show the 2003 permit was finalized; the permit description states “UPGRADE:ELECTRIC TO 200AMP” — an increase in capacity as described, not a confirmed installed rating.

Is it time to upgrade?

• Electrical service & panelCurrentLast permitted 2003 (23 years ago). City inspection record: PERMIT FINALED approved 2003-08-25. Contractor of record: BERT S ELECTRIC AND PLUMBING CO;*C. The permit describes an increase in capacity, which is the single best sign the electrical has actually been brought forward. T03EL01662 — UPGRADE:ELECTRIC TO 200AMP
• Heating & coolingNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2023 addition / alteration 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 Asphalt.
• Plumbing work on recordOn recordLast permitted 2023 (3 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. TC-RES-1023-08753 — Installation of new Private water service line from the Meter to 10' outside of the house (house Connection) part of Rodeo addition phase 2 TW project. The water line will be a 1-inch pex, buried at 14 inches. 12awg tracer wire will be taped to the pex every ten ft. from the new meter to the tie-in point. The new 5/8 meter will have a 1-inch meter valve installed on the customer's side.

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

  This is the aluminum branch-circuit window (roughly 1965–1973). Solid aluminum on 15/20 A circuits is a recognized fire hazard at the terminations and needs approved repair — COPALUM or AlumiConn, not a wire nut. 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

  100 A was typical. Adding an EV charger, heat pump, or casita usually forces a service upgrade first. The permit record does not confirm this; an on-site inspection is required.

Permit history (5)

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?

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.
