This Almaden Valley homeowner had a beautiful wood pergola in the backyard - and wanted two ceiling fans mounted to it. Simple enough idea. Getting power there cleanly was the part that took some planning.
We pulled the circuit from the home's SPAN smart panel, which we had installed over a year ago. From there, the wire ran through the crawl space under the house - keeping everything completely hidden until it reached the exterior wall. That's the cleanest route when a crawl space is available. No exposed wiring running along the house, no shortcuts.
Once the wire came through the exterior wall, we transitioned to conduit for the outdoor run. Pergolas are open to the elements, so anything running along the structure needs to be protected. The conduit follows the pergola framing to each fan location - functional and tidy. Both fans are outdoor-rated, which matters a lot when equipment is exposed to moisture and temperature swings year-round.
A couple of things worth knowing if you're thinking about adding fans or lights to a pergola. First, outdoor-rated fixtures are non-negotiable in an exposed setting like this. Second, the wiring method matters - conduit is required for exposed outdoor runs, not just stapled cable. And third, if your home has a crawl space, that's almost always the best path to route a new circuit to the backyard without it being visible.
The SPAN panel we installed previously made this job straightforward on the electrical supply side. Having a smart panel with available capacity meant we could add this circuit without any panel work - just run the wire, install the fans, test everything, and turn them on.
