Service on record

City records show the 2025 permit was finalized; the permit description states “upgrade from 100 to 200 amp service” — an increase in capacity as described, not a confirmed installed rating.

Is it time to upgrade?

• Electrical service & panelCurrentLast permitted 2025 (1 year ago). City inspection record: COT - RSEL - Electrical Final approved 2025-05-23. The permit describes an increase in capacity, which is the single best sign the electrical has actually been brought forward. TC-RES-0425-02141 — upgrade from 100 to 200 amp service
• Heating & coolingNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2025 historic preservation zone/historic landmark permit is on file (and 2 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 Evaporative 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 Built Up.
• 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

  GFCI protection was not required at all kitchen counter receptacles until the 1996 code. Expect gaps in kitchens, garages, and exterior outlets. The permit record does not confirm this; an on-site inspection is required.

• Worth confirming

  Solar was permitted here in 2025. That means there is an existing interconnection, and the main breaker and busbar rating already carry a PV backfeed — so anything else you add (an EV charger, a heat pump) has to be checked against what is left under the 120% rule, not against the service size alone.

• Era-based check

  Panels and breakers from this era are near the end of their service life even where the original installation was sound. The permit record does not confirm this; an on-site inspection is required.

Most recent permit on record for this parcel: 2026-03-23 (TR-ROW-0326-00337) — Sidewalk Repair, Repouring Concrete.

Permit history (12)

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.
