Service on record

A 2024 permit was issued; completion is not confirmed in the available record; the permit description states “upgrade electric service 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 2024 permit specifies this work (the permit description states “upgrade electric service 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. TC-RES-0724-04402 — upgrade electric service to 200 amps
• Heating & coolingLikely dueA newer 2024 permit for the same system is recorded as “Issued” — The work was permitted, but final completion is not confirmed. The permit description states “There is no HVAC System at this address. We are to perform a Manual J load calculation to determine the correct sizing for the unit to be installed. Install Heat Pump RTU 4 ton”. Last permitted 2001 (25 years ago). 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.
• 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

  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

  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.

• 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.

Most recent permit on record for this parcel: 2025-07-25 (TC-SOL-0725-01004) — Installation of a 9.42 kW (AC) PV System.

Permit history (6)

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.
