Service on record

City records show the 2006 permit was finalized; the permit description states “upgrade to 200 amps” — an increase in capacity as described, not a confirmed installed rating.

Flood and drainage — two different maps

The federal flood map and the local one are not the same map, and they do not always agree. FEMA’s is the insurance map. Pima County’s Regional Flood Control District and the City of Tucson regulate against their own, and that is the one a permit here is judged against.

Pima County RFCD local floodplains, floodways, sheet-flooding and erosion hazard areas, with the City of Tucson’s own mapped flood hazards. This is the map local floodplain regulation uses.

Parcel outlined in yellow. Both maps are drawn live from the agencies’ own map services at the same extent, so you can compare them directly. They are context for planning, not a floodplain determination — for that, ask the floodplain administrator for the jurisdiction shown below.

• FEMA: FEMA flood zone X — minimal flood hazard, not a Special Flood Hazard Area. FIRM panel 04019C2277L, effective 2011-06-16.
• Pima County RFCD: Pima County maps this location inside a special-studies floodplain delineation on Mountain Avenue Wash. County floodplain regulation applies here whatever the FEMA map shows — the two are separate maps with separate rules.
• City of Tucson: The City of Tucson maps a local flood hazard here on Mtn Ave Wash (flood). This is the City's own study, separate from the FEMA map.

Is it time to upgrade?

• Electrical service & panelCurrentLast permitted 2006 (20 years ago). City inspection record: ELECTRIC - FINAL approved 2006-02-22. Contractor of record: WINKLE ELECTRIC. The permit describes an increase in capacity, which is the single best sign the electrical has actually been brought forward. T06EL00204 — upgrade to 200 amps
• Heating & coolingLikely dueLast permitted 2006 (20 years ago). City inspection record: MECHANICAL - FINAL approved 2006-03-15. Contractor of record: AZTEC MECHANICAL MAINTENANCE. 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. Equipment from before about 2010 generally runs R-22, which has not been produced since 2020 — repairs mean reclaimed refrigerant at a price that often exceeds replacing the unit. T06ME00105 — Remove existing cooler and replace with 4ton A/C/120,000BTU Heat/Gas Pack
• Water heaterPermitted — completion not confirmedA 2003 permit specifies this work (the permit description states “REPLACE:GASLINE & WATER HEATER (APA)”), but the available record does not show a final inspection. The permit expired without a confirmed final status. Official status: Expired. T03PL00551 — REPLACE:GASLINE & WATER HEATER (APA)
• RoofNot in this windowNothing in the permit records we read for this parcel that names this system.
• 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

  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

  Solar was permitted here in 2016. 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.

Permit history (18)

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?

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.
