Is it time to upgrade?

  • Electrical service & distributionCurrentLast permitted 2016 (10 years ago). City inspection record: ELECTRIC - FINAL approved 2016-05-12. Contractor of record: CASCADE ELECTRIC INC *APA*. The permit describes an increase in capacity, which is the single best sign the electrical has actually been brought forward. Separately from replacement: NFPA 70E expects the arc-flash study to be reviewed at least every five years, or after any change to the service. T16CM02985 — UPGRADE UP TO 200AMP
  • Heating, cooling & mechanicalNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2023 right-of-way (row) permit is on file (and 1 more like it) — work like this is often folded into a larger permit without being named, so open that record and check its scope before concluding anything. Packaged rooftop units work 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. Worth confirming from the equipment nameplate rather than the record. Replacing a rooftop unit is also an electrical question: the new unit's minimum circuit ampacity and its disconnect often differ from the old one.
  • Fire alarm & life safetyNot in this windowNothing in the permit records we read for this parcel that names this system. Any alarm or sprinkler work here predates this feed. For an occupied commercial building that is worth confirming from the panel and the inspection tags rather than assuming.
  • RoofNot in this windowNothing in the permit records we read for this parcel that names this system. Roof age matters electrically too: it sets what can be penetrated for new rooftop units, conduit, or solar.

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

    Distribution gear this age is frequently past the point where the manufacturer still supports it. Breakers and fusible switches for obsolete lines can carry long lead times, which turns an outage into a shutdown. The permit record does not confirm this; an on-site inspection is required.

  • Worth confirming

    Multifamily property. House panels, unit meters, and common-area loads are usually metered and maintained separately — worth confirming which side of the meter a problem falls on before scheduling work.

  • Era-based check

    NFPA 70E expects arc-flash studies to be reviewed at least every five years, or after any change to the service. Buildings this age often have labeling that no longer matches the installed gear. The permit record does not confirm this; an on-site inspection is required.

Recorded sales are the sales the Pima County Assessor has on file from affidavits of property value — not every transfer, not listings, and not a valuation. Parties are never shown here. A sale with no permitted electrical work since is worth knowing before the next sale or a remodel.

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.

Code enforcement (25)

Code cases and housing-code violations recorded against this parcel, by category. Closed cases stay on the record, and most of these are closed — check the status column. We show the category and the official record number rather than the complaint text, which often names people who have nothing to do with the property.

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 13621683A — 169 permits on file from 1998 to 2026 (99 commercial building, 36 combo, 19 residential building - one or two family, 6 row) and 25 code enforcement cases — assembled from the Pima County parcel file, the City of Tucson’s Property Research Online file (permits back to about 2006, further on some parcels), and the City’s GIS permit and code-enforcement layers (2022 onward). Public records last checked 2026-08-16; 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.
