• Electrical service & panelNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2026 adu / casita permit is on file — 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 tell you the service is original — only that nothing has been permitted here recently. The build year is the better clue, and it is above.
• Heating & coolingNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2026 adu / casita permit is on file — 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 Wall and heating as Other. 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 Prepared Roll.
• Plumbing work on recordOn recordLast permitted 1998 (28 years ago). Plumbing permits cover everything from a full re-pipe to a few feet of sewer repair, so this is a record that work happened rather than a statement about the whole system. T98PL02302 — SEWER: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

  Knob-and-tube wiring may still be present in original, un-remodeled areas. It has no ground and is not rated for modern loads or insulation contact. The permit record does not confirm this; an on-site inspection is required.

• Era-based check — high priority

  Original services this age were 30–60 A fuse panels. Nearly every one still in place is undersized for a modern household. The permit record does not confirm this; an on-site inspection is required.

• Era-based check — high priority

  Branch circuits from this era are typically ungrounded two-wire — the reason you see two-prong outlets or ungrounded three-prong replacements. The permit record does not confirm this; an on-site inspection is required.

• Worth confirming

  An ADU or casita was permitted in 2026, 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.

Most recent permit on record for this parcel: 2026-02-11 (TR-ROW-0226-00181) — 03/31/26 (ieb)-- Renew for 30 days as of 3/27/26 new expiration date is 04/26/2026 Dunbar/Spring Neighborhood rain and tree planting: Excavating six street-side stormwater-harvesting basins, stabilizing basin banks with rock (except for the three shallow basins beside Perry Ave which have gradual 3:1 sloping banks and no rock), drilling one 4-inch diameter curb cores in street curb, planting native trees and/or Tucson Basin-native understory vegetation in basin terraces and basin bottoms. Addresses of all work sites: 722 and 730 N. Perry Avenue, 40 and 44 W. University Blvd NOTE 1: All sites were bluestaked, and field inspected by David Marhefka, City of Tucson Department of Transportation and Mobility landscape architect on 12-5-25 and APPROVED to proceed. NOTE 2: this is a resubmittal of application for permit. We have removed the site at 910 N. 10th Ave from this permit application as I was informed by Jonathan Knighton-Wisor that the 910 N 10th Ave site requires archaeological monitoring as it is within the old Court Street Cemetery area. Monitoring ensures compliance with A.R.S. §41-844, a state law that mandates reporting of mortuary features to the Arizona State Museum. NOTE 3: Additionally, this is a resubmittal of application for permit TR-ROW-0126-00037, which was a resubmittal of application for permit number TR-ROW-1225-01543). Only one address is listed on this permit application because this a permit for a neighborhood-wide project – the four addresses of the individual sites within the neighborhood are listed above. See the “Dunbar Spring Neighborhood Planting sites 2026 - polygon map” file for how the sites relate to one another within the neighborhood. This is how we do these community project permits every year - with all neighborhood sites under one neighborhood permit (David Marhefka helps facilitate this). If you have questions please contact the project coordinator, Brad Lancaster, at NeighborhoodForesters@gmail.com or 520-275-8753..

Permit history (6)

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 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?
