Electrical Service in Udall Park
Udall Park is a registered Tucson neighborhood in Ward 2. Of the homes here with a published build year, the median went up in 1979 — and in electrical terms, the year a house was built tells you most of what you need to know about what is behind its walls.
When Udall Park was built
Highlighted bands are the eras that carry a known electrical issue — pre-1950 knob-and-tube, the 1965–1973 aluminum branch-circuit window, and the 1974–1989 Federal Pacific / Zinsco panel years.

Federal Pacific and Zinsco panels
About 88% of the housing stock here dates to 1974–1989, when Federal Pacific Stab-Lok and Zinsco/Sylvania panels were still being installed. Both have documented failure-to-trip histories, and the failure is in the breaker-to-bus connection itself — so fitting a new breaker does not resolve it, which is why the panel is what gets replaced once you need to add a circuit.

Check your actual address
Neighborhood averages are a starting point, not an answer. Our free Property Electrical Profile reads the county record for one specific parcel — the build year, the assessor’s use and zoning, and the permit history — and tells you what that suggests about the service, the wiring era, and the panel.
