Ethernet, Wi-Fi & Smart Home Wiring in Bellevue, WA

Bellevue homes run the full range: 1950s-to-70s ramblers and split-levels in Lake Hills, Crossroads and Eastgate, hillside houses in Somerset and Newport spread over several levels, larger new and rebuilt homes in West Bellevue, and downtown condos and offices. Each needs a different network plan, so we design around the house instead of selling one kit.

Our Bellevue work leans toward whole-home Ethernet, wired Wi-Fi with UniFi access points, home theater wiring and smart lighting — often planned alongside a remodel or new build, when getting the wiring right the first time saves opening walls later.

Hillside homes in Somerset and Newport are the classic Bellevue Wi-Fi problem. The internet comes in on one level, and the bedrooms and office are two floors and a lot of framing away. Mesh nodes talking to each other over the air through those floors lose speed with every hop. The dependable fix is a wired access point on each level, each fed by its own Cat6 run back to one central spot. Our comparison of mesh and wired access points goes into why.

New and rebuilt homes, common in West Bellevue and Bridle Trails, are the best time to wire. With the walls open, a drop costs far less than fishing one later, and it's the moment to decide where the network rack lives, which rooms get TV and access-point drops, and whether any run is long enough to need Cat6A. Our guide to how many Ethernet drops a new home needs is a good starting list.

The mid-century ramblers in Lake Hills and Eastgate are usually straightforward retrofits: with an attic or crawlspace to work from, most drops need only the hole where the jack goes. Downtown condos are the opposite. There's no attic, some walls are concrete, and the building has rules about what can change, so in-unit work is usually about better access-point placement and making good use of whatever wiring is already there.

Ethernet, access points and camera cabling inside a house don't need a permit in Washington. Electrical work does: new circuits, EV chargers and panel changes are permitted and inspected through whichever office has electrical jurisdiction — the city or Washington L&I — and we handle the permit and meet the inspector. Bellevue is Puget Sound Energy territory, so a panel upgrade that changes the service is scheduled with PSE.
