Service on record

City records show the 2016 permit was finalized; the permit description states “200A SERVICE UPGRADE (VH)” — an increase in capacity as described, not a confirmed installed rating.

Is it time to upgrade?

• Electrical service & panelCurrentLast permitted 2016 (10 years ago). City inspection record: ELECTRIC - FINAL approved 2016-06-17. Contractor of record: BUDDY HEILIG AND SONS ELECTRICAL INC. The permit describes an increase in capacity, which is the single best sign the electrical has actually been brought forward. T16EL00116 — 200A SERVICE UPGRADE (VH)
• Heating & coolingNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2023 neighborhood preservation zone (npz) 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. The assessor records cooling as Refrigeration and heating as Forced Air. 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. The assessor records the roof as Built Up.
• 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. 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

  This is the aluminum branch-circuit window (roughly 1965–1973). Solid aluminum on 15/20 A circuits is a recognized fire hazard at the terminations and needs approved repair — COPALUM or AlumiConn, not a wire nut. The permit record does not confirm this; an on-site inspection is required.

• Era-based check — high priority

  Federal Pacific (Stab-Lok) and Zinsco/Sylvania panels were sold through this period. Stab-Lok breakers have a documented history of failing to trip internally; Zinsco breakers can weld to the bus so the handle moves without breaking the circuit. In both cases a replacement breaker does not resolve it — the panel itself is what gets replaced. The permit record does not confirm this; an on-site inspection is required.

• Era-based check

  100 A was typical. Adding an EV charger, heat pump, or casita usually forces a service upgrade first. The permit record does not confirm this; an on-site inspection is required.

• Worth confirming

  An ADU or casita was permitted in 2023, which means load has already been added to this property. Whether there is headroom left for anything more depends on how that was fed — a subpanel off the existing service, or its own.

Recorded sales (1)

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.

Most recent permit on record for this parcel: 2025-02-27 (TC-RES-0225-01088) — VOID: OS - Duplicate/Same scope of work as existing application permit TC-RES-0225-01069. Please resubmit your site plan with the complete address including unit number to your existing permit, or withdraw existing permit before moving forward with a new application. Repair: replace 200 amp riser conduit.

Permit history (8)

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?

Utility and upgrade pathElectric service here is Tucson Electric Power (TEP). A service or panel upgrade needs a TEP meter release and has to meet TEP’s service requirements — meter height and location, clearances, and the point of attachment. See TEP new-service requirements and the TEP standards notes.
