Campbell-Grant Northeast: permit history and electrical signals

Campbell-Grant Northeast by the numbers

Among the 12 neighborhoods in this hub, Campbell-Grant Northeast ranks 5th for permit activity per home since 2022, 4th for panel and service upgrades per home (2.3 per 100 homes with a build year), and 1st 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.

Highlighted bands are the eras that carry a known wiring or panel issue in Tucson housing.

Knob-and-tube and ungrounded circuits

About 24% of the homes with a published build year here predate 1950. In original, un-remodeled areas that can still mean knob-and-tube wiring — no ground, not rated for modern loads, and not safe in contact with blown-in insulation. It is also why so many houses in this part of town still have two-prong outlets, or three-prong outlets with nothing behind the ground pin. Both are fixable, and neither is an emergency on its own. That is the 7th-largest share of the 12 neighborhoods in this hub.

Post-war services and ungrounded circuits

About 60% 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 4th-largest share of the 12 neighborhoods in this hub.
