Is it time to upgrade?

  • Electrical service & panelCurrentLast permitted this year (2026). The permit describes an increase in capacity, which is the single best sign the electrical has actually been brought forward. P26BP02118 — Electrical Equipment — panel upgrade 200 amps
  • 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, so we read the county’s own permit system — including its historical permits, which reach back into the 1990s where they exist. Every record links to the county’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

  • Worth confirming

    This reads as a manufactured or mobile home. The electrical questions are different from a stick-built house: the service and meter usually sit on a separate pedestal, and the feeder from that pedestal to the home is where undersizing and corrosion show up first.

  • Worth confirming

    Bonding and grounding are the common finding on older units — the frame must be bonded, and the neutral and ground have to stay separated downstream of the service disconnect at the pedestal.

  • Routine

    Adding an EV charger, a mini-split, or a casita usually means looking at the pedestal service and feeder capacity rather than the panel inside the home.

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 issuing office’s official file — Pima County’s portal for county permits, the City of Tucson’s for city records. 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. See an error in this public-record report?

How this report was built

This is a reading of public records for parcel 212382370 — 10 permits on file from 1988 to 2026 (8 historical, 1 electrical / mechanical, 1 other structures) — assembled from the Pima County parcel file, the City of Tucson GIS layers, and Pima County’s Accela permit portal (searched by parcel and by address, because the county’s parcel links break on older records). Public records last checked 2026-08-17; the record is re-read at least weekly. Each permit and code case links to its official file. 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. A permit that is present is strong evidence; a permit that is absent is weak evidence — plenty of work is never permitted, and older county records were only partly moved online.

The interactive version of this report can also read the plan sheets behind a City of Tucson permit and write a contractor’s brief of the whole record — those buttons appear once the page finishes loading.
