Glendale’s housing stock reflects decades of steady growth, and that shows up in our service calls. In Rossmoyne, a hillside neighborhood established in the 1920s with Colonial, Spanish Revival, and Tudor homes, we regularly find original knob-and-tube wiring and undersized subpanels that were never designed for modern kitchens or window AC units. Verdugo Woodlands, tucked against the Verdugo Mountains, has a similar mix of vintage homes on larger lots, while Adams Hill’s mid-century housing tends to need service upgrades to support EV chargers and added circuits. Glendale is one of the few cities in this area with its own municipal electric utility — Glendale Water & Power — rather than Southern California Edison, so service connections and meter clearances run through GWP directly. Electrical permits go through the City of Glendale Community Development Department’s Building & Safety Permit Services Center, and any new service or upgrade also requires GWP clearance before the permit is finalized. Hot, dry summers in the foothill neighborhoods put steady strain on older air conditioning circuits, which is a common trigger for panel calls.
