Is it time to upgrade?

• Electrical service & panelFinaled permit foundLast permitted 2009 (17 years ago). The permit describes an increase in capacity, which is the single best sign the electrical has actually been brought forward. T09EL01919 — UPGRADE: ELECTRIC TO 3O A 240V CIRCUIT TO WATER HEATER
• Heating & coolingNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2017 addition / alteration 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 WARMED AND COOLED AIR 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 heaterLikely dueLast permitted 2009 (17 years ago). T09EL01919 — UPGRADE: ELECTRIC TO 3O A 240V CIRCUIT TO WATER HEATER
• RoofNot in this windowNothing in the permit records we read for this parcel that names this system. The assessor records the roof as Composition Shingle.
• Plumbing work on recordOn recordLast permitted 2011 (15 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. T11PL00643 — PLUMBING:REPLACE WATER LINES TO MH PARK

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 digitized. 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

  A finaled 2009 panel/service permit is on record for this parcel, which makes it unlikely the original 60–100 A equipment is still in place. That is a permit record, not an inspection — verify the installed rating and the panel brand on site before sizing anything new. The permit record does not confirm this; an on-site inspection is required.

• Worth looking at

  There is an open code enforcement case on this parcel. An open case can hold up a permit, and if it touches unpermitted work the electrical scope usually has to be brought up to code as part of resolving it.

• Worth confirming

  Bonding and grounding are the common finding on older units — the frame must be bonded, and the neutral and ground have to stay separated downstream of the service disconnect at the pedestal.

• Worth confirming

  There is an electrical reconnect permit from 2025. The service was disconnected at some point and brought back — usually after a vacancy, a utility disconnect, or work that required the power off. Worth knowing what prompted it.

• Worth confirming

  A pool or spa was permitted in 2003. Pool equipment brings its own bonding grid, GFCI requirements, and usually a subpanel — and the bonding rules have tightened since, so older installations are worth verifying.

• Routine

  Adding an EV charger, a mini-split, or a casita usually means looking at the pedestal service and feeder capacity rather than the panel inside the home.

• Routine

  A trade permit was pulled in 2017. Trade permits cover electrical, plumbing, and mechanical work individually, so some permitted trade work has been done here since.

What to check at the panel

Everything above is read off public records. These are the things only someone standing at the panel can settle, and they take about a minute. Check them against the rating the permit above describes rather than against the era — the permit is the better evidence, and neither one is an inspection.

1. The rating on the main breaker at the service pedestal, not the panel inside the home — the pedestal is the service.
2. The condition of the feeder running from the pedestal to the home, and its rating. Undersizing and corrosion show up here first.
3. Whether the frame is bonded, and whether neutral and ground are separated downstream of the pedestal disconnect. This is the most common finding on older units.
4. Whether the water heater, dryer and range are gas or electric — no public record carries fuel type, and it is the single biggest variable in what the service can still take.

Service on record

City records show the 2009 permit was finalized; the permit description states “UPGRADE: ELECTRIC TO 3O A 240V CIRCUIT TO WATER HEATER” — an increase in capacity as described, not a confirmed installed rating.

The living area, cooling and heating above come from the Pima County Assessor’s record, as we read it on 28 Jan 2026. Each other row names its own source.

The most recent permitted work on this parcel was in 2026. That says the parcel was worked on under permit, not what the work covered — a roof, a pool or a changeout tells you nothing about the electrical service. Work done without a permit leaves no trace here at all.

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.

The contractor’s read is a plain-English brief of the record above, written by AI — what it shows across electrical, mechanical and the building itself, what is missing for the era, and what to verify on site.

What the flood note is not. The FEMA map linked above is the National Flood Hazard Layer — the federal insurance map. Local floodplain mapping is not reproduced here; use the authority’s own map, linked above. Nothing here is a floodplain determination, an elevation certificate, or a substitute for one. A parcel can straddle a boundary, and a Letter of Map Amendment can remove a structure the map still covers. For a determination, ask the floodplain administrator for the jurisdiction named above; for a design that has to satisfy one, that is work we do.
