Corbett: permit history and electrical signals

Corbett by the numbers

Among the 12 neighborhoods in this hub, Corbett ranks 3rd for permit activity per home since 2022, 8th for panel and service upgrades per home (1.7 per 100 homes with a build year), and 4th for the share of pre-1974 housing.

Counts are City of Tucson GIS permit layers 85 (residential), 81 (commercial) and 102 (code enforcement) inside the neighborhood boundary, issued or opened on or after 1 January 2022 — the window those layers cover. Older permits exist in the City’s Property Research Online file and show up in the per-address report. Build years are the assessor’s published values, which stop at 2009. “Per 100 homes” divides by homes with a published build year; the comparison figure uses the same measure summed over the City’s 140 registered neighborhoods, not every parcel in the city.

Post-war services and ungrounded circuits

About 79% went up between 1950 and 1964 — Tucson's post-war boom. Services from those years were 60 to 100 amps, often a fuse panel since swapped for breakers without the service itself ever being enlarged. Grounded branch circuits did not become the norm until the early 1960s, and the cloth jacket on that era's cable embrittles in a Tucson attic. That is the 3rd-largest share of the 12 neighborhoods in this hub.
