New Construction installation in San Francisco, CA
Prewire is the cheapest technology decision in a build. While walls are open, cable costs a fraction of what a retrofit does, so the goal is to place more pathways than you think you need — Ethernet drops, ceiling locations for access points, camera runs and a central panel.

Local considerations
- Narrow three- and four-level homes are the norm, and vertical coverage is the hard part — one access point per level, wired where a chase exists, is the usual answer.
- Plaster and lath with wire mesh blocks Wi-Fi far more than drywall, which is why mesh systems often underperform here.
- Garage-level utility rooms make good rack locations and give a straightforward cable path up through the building.
Common home types here: Multi-level Victorians and Edwardians, Condos and flats, Garage-level offices.
What a good prewire includes
- Two Ethernet drops at each office, TV and desk location
- Ceiling drops for access points on every floor
- PoE camera runs at entries, driveway and approaches
- Speaker and AV pathways, plus conduit for future upgrades
- A ventilated, powered panel or rack location central to the home
How much does low-voltage prewire cost for a new home?
Prewire is priced per location — Ethernet jacks, access point drops, camera drops, TV and speaker locations — and it costs a fraction of retrofit work because the walls are open. The biggest cost risk is not the prewire itself but a location you skip and have to add after drywall.
