Wifi is great until it isn't. Every San Jose tech-forward homeowner regrets not running these three cables during construction: Cat 6A ethernet to every room, RG-6 quad-shield to media walls, and a dedicated low-voltage chase between every floor.
Cost to run during construction: $400–$800 for a typical 2,500 sq ft home. Cost to retrofit later: $4,000–$8,000 with extensive drywall repair.
Bonus tier: also run a 1.5" conduit from your media closet to your living room TV wall. Cable standards change every 8–10 years — conduit lets you future-proof.
Bay Area smart-home pros on HandyMandyMan handle this kind of low-voltage prep daily. Book before drywall, not after.
