• Electrical service & panelNot in this windowNothing in the permit records we read for this parcel that names this system. Nothing permitted on the service shows in the record we read. For a home built in 1922 that leaves the original service era in play — the panel makes and wiring methods of that era are exactly what the era check above flags, and only a look at the panel settles it.
• Heating & coolingNot in this windowNothing in the permit records we read for this parcel that names this system. The assessor records cooling as WARMED AND COOLED AIR 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 Composition Shingle.
• 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 digitized. 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.

• Worth confirming

  A pool or spa was permitted in 2024. Pool equipment brings its own bonding grid, GFCI requirements, and usually a subpanel — and the bonding rules have tightened since, so older installations are worth verifying.

What to check at the panel

Everything above is read off public records. These are the things only someone standing at the panel can settle, and they take about a minute.

1. The number stamped on the main breaker handle — 100, 125, 150, 175 or 200. That is the service rating, and no record on this page confirms it.
2. The busbar rating printed on the panel label. It is a different number from the main breaker, and it is the one that decides how much solar a panel can take under the 120% rule.
3. The manufacturer and catalog number on the label inside the door.
4. How many full-size spaces are left, how many positions the label permits a tandem breaker in, and the tandem limit the label states. A full panel is a different job from a full service.
5. The conductor material at the main lugs, and whether the terminations look clean and tight.
6. Whether there is a separate meter-main outside as well as the panel indoors — that changes where a disconnect and any new feeder would land.
7. Whether the water heater, dryer and range are gas or electric. No public record carries fuel type, and it is the single biggest variable in a load calculation — it can move the calculated load on the same house by more than 40 A.
8. Whether any knob-and-tube is still live where it is visible — in the attic, the basement or a crawlspace — and whether insulation has been laid over it.
9. Whether receptacles are two-prong, and whether any three-prong replacements have an actual ground behind them. A $10 tester answers this at every outlet.
10. Whether the kitchen counter, bathroom, garage and exterior receptacles have GFCI protection, and whether the test button actually trips them.

The living area, cooling and heating above come from the Pima County Assessor’s record, as we read it on 28 Jan 2026. Each other row names its own source.

The most recent permitted work on this parcel was in 2026. That says the parcel was worked on under permit, not what the work covered — a roof, a pool or a changeout tells you nothing about the electrical service. Work done without a permit leaves no trace here at all.

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.

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.

What the flood note is not. The flood zone shown is FEMA’s National Flood Hazard Layer — the federal insurance map. Local floodplain mapping is not reproduced here; use the authority’s own map, linked above. Nothing here is a floodplain determination, an elevation certificate, or a substitute for one. A parcel can straddle a boundary, and a Letter of Map Amendment can remove a structure the map still covers. For a determination, ask the floodplain administrator for the jurisdiction named above; for a design that has to satisfy one, that is work we do.
