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 2026 solar pv 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 & mechanicalCurrentA newer 2024 permit for the same system is recorded as “Issued” — The work was permitted, but final completion is not confirmed. The permit description states “in the classroom building we are expanding four classrooms as well as replacing and adding new HAVC rooftop units. in the child care building we are adding three new ADA restrooms.”. Last permitted 2023 (3 years ago). City inspection record: COT - LCEL - Electrical Final approved 2024-11-20. 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. TC-COM-0623-01545 — in the classroom building we are expanding four classrooms as well as replacing and adding new HAVC rooftop units. in the child care building we are adding three new ADA restrooms.
• Fire alarm & life safetyCurrentLast permitted 2021 (5 years ago). Panels and devices age out on their own schedule, and the code moves underneath them — a system that was compliant when installed is not automatically compliant now. T21FC00316 — Installation of Buckeye Fire Suppression System
• 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

  Gear in this age range is usually still supported but is due for infrared scanning and torque verification if that has not been done recently. 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 2026. 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.

Most recent permit on record for this parcel: 2026-02-11 (TC-COM-0226-00201) — Installation of New Solis: S6-GC30K-LV-US PERMANENTLY DERATED TO 10.00KW / NEW Meter Socket/ New DG disconnect switch (existing solar system).

Permit history (33)

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 (1)

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.

Record numbers link to the City of Tucson’s official file. 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?
