Service on record

A 2025 permit was issued; completion is not confirmed in the available record; the permit description states “Upgrading main electrical panel from 100 amps to 200 amps.” — an increase in capacity as described, not a confirmed installed rating.

Is it time to upgrade?

• Electrical service & panelPermitted — completion not confirmedA 2025 permit specifies this work (the permit description states “Upgrading main electrical panel from 100 amps to 200 amps.”), but the available record does not show a final inspection. The work was permitted, but final completion is not confirmed. Official status: Inspections. City inspection record: COT - RSEL - Electrical Final approved 2026-03-09. TC-RES-1025-05113 — Upgrading main electrical panel from 100 amps to 200 amps.
• Heating & coolingNot in this windowNothing in the permit records we read for this parcel that names this system. 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.
• RoofPermitted — completion not confirmedA 2025 permit specifies this work (the permit description states “Re-roof with a darker color”), but the available record does not show a final inspection. The permit expired without a confirmed final status. Official status: Expired. TC-RES-0125-00540 — Re-roof with a darker color
• 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.

Most recent permit on record for this parcel: 2025-10-20 (TC-RES-1025-05113) — Upgrading main electrical panel from 100 amps to 200 amps..

Permit history (8)

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?

Utility and upgrade pathElectric service here is Tucson Electric Power (TEP). A service or panel upgrade needs a TEP meter release and has to meet TEP’s service requirements — meter height and location, clearances, and the point of attachment. See TEP new-service requirements and the TEP standards notes.
