Blenman-Elm: permit history and electrical signals
City of Tucson neighborhood in Ward 6 — north: All lots located on the North side of Elm Street between Tucson Boulevard and Campbell Avenue and including those lots both on the cul-de-sac named Potter Place and in the development known as Potter Park, both of which are accessed from the north side of Elm Street at Wilson Ave., east: Country Club Rd, south: Speedway Blvd, west: Campbell Ave/Tucson Blvd. What the public record says about how old the houses are, what has been permitted since 2022, and what that usually means electrically — measured from the City’s own GIS layers, not estimated.
Blenman-Elm by the numbers
Among the 12 neighborhoods in this hub, Blenman-Elm ranks 11th for permit activity per home since 2022, 10th for panel and service upgrades per home (1.3 per 100 homes with a build year), and 6th 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.
When Blenman-Elm was built
Highlighted bands are the eras that carry a known wiring or panel issue in Tucson housing.
Knob-and-tube and ungrounded circuits
About 53% 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 3rd-largest share of the 12 neighborhoods in this hub.
Post-war services and ungrounded circuits
About 28% 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 10th-largest share of the 12 neighborhoods in this hub.

What we do with this in Blenman-Elm
In Blenman-Elm the record since 2022 shows 19 permitted panel or service upgrades since 2022 (10th of 12 per home), 14 HVAC changeouts, 24 remodels or additions, 8 solar installs across 1,432 homes with a build year — pre-war and post-war housing where the panel, the service and the branch wiring are usually the first questions.
