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.

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 04019C2304L, effective 2011-06-16.
• Pima County RFCD: No Pima County regulated local floodplain, floodway, sheet-flooding area or erosion hazard area is mapped at this location. That is the county's map, not a statement about drainage on the site.

Is it time to upgrade?

• Electrical service & panelNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2020 solar pv 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 2020 solar pv 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 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

  Solar was permitted here in 2020. 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.

Recorded sales (2)

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: 2023-08-24 (TC-RES-0823-07579) — ROOF MOUNTED PV SYSTEM 7.22kW DC / 11.00kW AC 19 modules.

Permit history (2)

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.
