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 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. 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 A — Special Flood Hazard Area (1% annual chance flood); floodplain rules and elevation requirements typically apply to new exterior equipment and structures. FIRM panel 04019C1693L, effective 2011-06-16.
• Pima County RFCD: Pima County maps this location inside a special-studies floodplain delineation. County floodplain regulation applies here whatever the FEMA map shows — the two are separate maps with separate rules.
• Base flood elevation: the county maps 9 BFE contours near this parcel, 2366–2375 ft NAVD88. Those are contour lines near the property, not an elevation certified for this site.
• City of Tucson: its flood-hazard mapping covers City limits only and does not apply to this parcel. The jurisdiction above is the one to ask.

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 2024 electrical / mechanical 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 2024 electrical / mechanical 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. 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.
• 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. This parcel is in unincorporated Pima County, so we read the county’s own permit system — including its historical permits, which reach back into the 1990s where they exist. Every record links to the county’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 2024. 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 (11)

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 issuing office’s official file — Pima County’s portal for county permits, the City of Tucson’s for city records. 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 out here is split: Trico Electric Cooperative serves much of unincorporated Pima County, Tucson Electric Power serves the rest, and a few areas sit on other systems. The meter release, clearances and point of attachment for an upgrade come from whichever utility serves the meter — check a recent bill or the meter label. See TEP new-service requirements for the TEP side.
