Built 1916 — pre-1950 knob-and-tube era · no permits on record for this parcel

Is it time to upgrade?

  • 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 1916 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. 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. This parcel is in unincorporated Pima County, whose building permits are issued by Pima County Development Services and are not part of this record — what is shown here comes from the regional records, and is likely incomplete for this address. A records request to the county is the authoritative check. 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.

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.

With those in hand you can run the numbers yourself. The load calculator does the NEC 220.82 optional-method calculation — the same method a permit application uses — and shows its work.

What these jobs cost here

The public record for this parcel is too thin to price it honestly — only build year is known for this parcel — not enough to price it as anything but a city average. Rather than show you a number that is really just a Pima County average wearing this address, the calculator will ask you the four or five things that actually decide it and price it properly.

Flood and drainage

The federal flood map and the local one are not the same map, and they do not always agree. FEMA’s is the insurance map; Pima County Regional Flood Control District regulates against its own, and that is the one a permit here is judged against.

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

Nothing on record for this parcel or street in Pima County's online permit system. The county's older records were only partially moved online, so this is meaningful for recent decades and weak evidence about anything older — and plenty of work is never permitted 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 in this area is largely Trico Electric Cooperative; parts are Tucson Electric Power. That matters for an upgrade: the meter release, the required clearances and the point of attachment come from whichever utility serves the meter, and Trico’s process is its own. Check a recent bill or the label on the meter — and see TEP new-service requirements for the TEP side.

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.

How this report was built

This is a reading of public records for parcel 40123011A — no City of Tucson permits on file (City records reach back to the mid-1990s) — assembled from the Pima County parcel file and the City of Tucson’s published permit layers together with the City’s own migrated permit archive, whose records reach back to the mid-1990s. Some records were still not read for this snapshot: City permit records before the mid-1990s were never fully digitized, and this parcel is in unincorporated Pima County, whose own permits (the county’s Accela portal) were also not read. The construction year, living area on this page come from our saved copy of the Assessor’s own published data file (dated 2026-01-28). The sewer connection file and the flood map were not read for this snapshot. Absence of a permit here is NOT evidence work was never permitted — it may predate the digitized record or sit in a system this snapshot did not read. Public records snapshot taken 2026-08-22.

The verdicts are inferences from what was permitted and when, and from the era the building went up; they are not an inspection, and nothing here confirms what is installed. Written and maintained by Arizona Electrical Solutions, LLC, a licensed Tucson contractor (ROC 276948 CR-11 electrical, ROC 326401 CR-39 HVAC, ROC 329360 KB-1, ROC 312437 KA).
