New Construction installation in San Mateo, 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

Much of San Mateo's housing stock dates from the 1940s to 1970s — plaster walls and limited attic access are common, so cable pathways are planned before anything is cut.
Two-story homes on small lots are frequent here, which makes an upstairs access point on wired backhaul the most common fix for weak bedroom coverage.
Detached garages converted to offices and ADUs are a regular request, usually solved with a fiber or conduit run across the yard.

Common home types here: Mid-century single-story, Two-story on small lots, Converted garages and ADUs.

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.
