Service on record

City records show the 2003 permit was finalized; the permit description states “UPGRADE:ELECTRIC 100AMP TO 200AMP (APA)” — an increase in capacity as described, not a confirmed installed rating.

Is it time to upgrade?

• Electrical service & panelCurrentLast permitted 2003 (23 years ago). City inspection record: ELECTRIC - FINAL approved 2003-09-10. Contractor of record: DESERT HILLS ELECTRIC INC,*C. The permit describes an increase in capacity, which is the single best sign the electrical has actually been brought forward. T03EL01619 — UPGRADE:ELECTRIC 100AMP TO 200AMP (APA)
• 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.
• 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 — high priority

  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 — high priority

  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.

The most recent permitted work on this parcel was in 2017 — recent enough that a modern service and grounding were required at the time. 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.
