Is it time to upgrade?

• Electrical service & panelFinaled permit foundLast permitted 2020 (6 years ago). The permit describes an increase in capacity, which is the single best sign the electrical has actually been brought forward. T20CM01013 — E - NEW PANEL UPGRADE 400AMP
• Heating & coolingFinaled permit foundA newer 2025 permit for the same system is recorded as “Inspections” — The work was permitted, but final completion is not confirmed. The permit description states “Unit 11 We will run a 20ft section of 1” pipe from the meter up to roof once on roof we will drill a hole through block wall run a 5ft section of 1” pipe to furnace once at furnace we will go into unit and cut a section of drywall drilling a hole up to roof. Once hole is made we will install a 1”x3/4 tee on roof and run a 2ft section of 3/4 pipe to furnace installing a new gas shut off valve and supply line we will then go into unit cut drywall and run a 3/4 pipe down into unit to water heater installing a gas valve and supply line. Once the repair is complete, we will put the unit on test and check for leaks. Once no leaks are found, we will clean up all debris.”. Last permitted 2025 (1 year 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.

• 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

  A finaled 2020 panel/service permit is on record for this parcel, which makes it unlikely the original 100 A equipment is still in place. That is a permit record, not an inspection — verify the installed rating and the panel brand on site before sizing anything new. The permit record does not confirm this; an on-site inspection is required.

• 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.

• Routine

  A trade permit was pulled in 2025. Trade permits cover electrical, plumbing, and mechanical work individually, so some permitted trade work has been done here since.

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. Check them against the rating the permit above describes rather than against the era — the permit is the better evidence, and neither one is an inspection.

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. The brand on the door or the breaker faces. Federal Pacific panels usually read “Federal Pacific Electric” or “FPE”; Zinsco panels read “Zinsco”, or on later stock “Sylvania” or “Sylvania-Zinsco”. Finding a Square D, Eaton, Cutler-Hammer, Siemens or GE panel here is the ordinary result and is not a finding — those are current, supported lines with breakers on the shelf.
9. The conductors landing on the 15 and 20 A breakers. Silver-coloured rather than copper is the 1965–1973 solid-aluminum branch-circuit question, and it is repaired at the terminations, not by replacing the panel. The aluminum feeder between meter and panel, and the aluminum service conductors overhead, are normal on houses of every era and are a different thing entirely.
10. Whether the kitchen counter, bathroom, garage and exterior receptacles have GFCI protection, and whether the test button actually trips them.

Solar potential

The county’s building-footprint layer maps ≈ 3,150 sq ft of roof plan area here across 2 structures. In Tucson a rooftop array produces about 1,645 kWh per installed kW per year (PVWatts), so a typical 6–8 kW home system fits on a fraction of that roof and makes roughly 10,000–13,000 kWh a year. TEP credits exported surplus at its RCP rate — about 5¢/kWh for new applications, locked for 10 years — so sizing to the home’s own use matters more than filling the roof. If solar shows in this property’s permit record, check whether it was permitted and finaled.

Service on record

City records show the 2020 permit was finalized; the permit description states “E - NEW PANEL UPGRADE 400AMP” — an increase in capacity as described, not a confirmed installed rating.

The most recent permitted work on this parcel was in 2025. 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 FEMA map linked above is the 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.
