Heinze Contracting LLC.

The permits on record run from 2025 into 2026, filed in Spokane, Greenacres and Shoreline, all residential electrical work. That lines up with what the business lists as its services: service upgrades, circuit rewiring and hot tub electrical installation. The state lists Ryan Heinze and Katherine Heinze as principals since 2025. Heinze Contracting is based in Otis Orchards and works within roughly a 25-mile reach, which covers Spokane Valley and the city of Spokane without stretching far. This is a small residential outfit that takes most of its work through referrals and repeat customers. It fits a homeowner replacing an undersized panel to carry a heat pump, range or EV charger, adding a dedicated circuit for a backyard spa, or re-feeding circuits in an older house. Large commercial electrical contracting is outside what the record shows, and so is the kind of quick online booking bigger shops advertise. Spokane's housing runs from early-1900s homes on the South Hill and in the older neighborhoods to postwar ranches and newer subdivisions in the Valley. Older houses often still have small services, aging panels and circuits that were extended piecemeal over the decades, so a panel upgrade can turn up wiring that needs attention too. Newer homes usually have capacity but may need a fresh circuit for a hot tub or shop. Before work starts, ask what the electrician expects to find behind the panel and how the permit and inspection will be handled.
