Is it time to upgrade?

  • Electrical service & distributionNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2025 electrical / mechanical permit is on file (and 2 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. That does not mean the gear is original — only that nothing has been permitted here recently. Where it matters is capacity: obsolete distribution lines carry breaker and fusible-switch lead times that turn an outage into a shutdown, and that is worth knowing before a new tenant or a new rooftop unit. 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.
  • Heating, cooling & mechanicalNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2025 electrical / mechanical permit is on file (and 2 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. The assessor records cooling as Refrigeration and heating as Forced Air. 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. The assessor records the roof as Built Up. 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. 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

  • 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.

  • 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.

  • Worth confirming

    Solar was permitted here in 2025. That means there is an existing interconnection, and the main breaker and busbar rating already carry a PV backfeed — so anything else you add (an EV charger, a heat pump) has to be checked against what is left under the 120% rule, not against the service size alone.

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.

Showing the 31 most recent county records — this parcel has more. The full set is on Pima County’s permit portal (search the parcel number).

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 21334153A — 31 permits on file from 1990 to 2026 (11 historical, 5 right of way, 4 addition / alteration, 4 electrical / mechanical) — 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 2026-08-16; 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.
