Sebastopol's housing stock skews older — 1920s craftsman bungalows, mid-century west-county homes, converted farmhouses, and a healthy population of cabins and ADUs. The electrical patterns are predictable, and most of them have a fix. Here's what we see most in Sebastopol.
Knob-and-tube — yes, it's still out there
Pre-1940s Sebastopol homes still occasionally have active knob-and-tube wiring in attics or behind original plaster. K&T wasn't bad in its day — but it lacks a ground, can't safely carry modern loads, and most insurers will not write coverage with it active. Our standard plan: a phased rewire to copper romex with a new panel.
Cloth-jacketed wiring
1940s–60s Sebastopol homes commonly have cloth-jacket NM cable. The conductors are usually fine; the cloth is brittle. The right approach depends on condition — sometimes a full rewire, sometimes a panel + targeted re-pulls in critical spaces.
Undersized service
60A and 100A services are common in Sebastopol. They're often fine for the as-built load but tap out the moment the homeowner adds AC, a heat pump, or an EV charger. Plan the panel upgrade before the load addition, not after.
ADU and accessory units
Sebastopol has more ADUs and accessory structures per capita than most of Sonoma County. The electrical question always becomes: sub-panel or new service? We size based on the load you're actually planning, not a worst-case spec sheet.
Outdoor, well, and irrigation circuits
Rural Sebastopol properties typically have well pumps, irrigation, gates, and outbuildings. These circuits are older than the rest of the home, often ungrounded, and often misfused. They're worth a once-over during any other work.
