Hillside framing at MacDonald Ranch and where cable can go
Building up a slope means stepped pads and split floor levels, and that changes the cable conversation more than it changes the bracket. In a flat-pad house the stud bay behind the TV usually runs clear from bracket height to the outlet. On a stepped hillside lot, the floor framing under a great room can interrupt that bay partway down, and there is no basement anywhere in the valley to drop into as an alternative. So we plan the route before drilling: down the bay where it runs clear, sideways into the next bay where it does not, or a paint-matched raceway where a patch would land mid-feature-wall. Concealment is $99 per TV either way. We keep low-voltage cable a hand's width from the electrical in the cavity, and avoid the attic, because summer heat under a tile roof shortens the life of HDMI. Where a full-motion arm is going in, we leave a service loop long enough for the full extension, since a cable pulled tight at the swing limit fails at the connector. Add 30 to 50 minutes for a concealed run.
