When a general contractor calls us before framing inspection instead of after drywall, the job goes faster and costs less to fix. Low Voltage Components (LVC) is a licensed C7 low-voltage contractor based in Escondido, serving custom home builders throughout North County — Rancho Santa Fe, Del Mar, Encinitas, Carlsbad, Poway, San Marcos and Fairbanks Ranch. We handle network, audio, video, security and automation rough-in on new builds, and getting low voltage pre-wire new construction San Diego projects right starts before insulation goes in, not after. This is the same checklist we hand builders and their electricians on day one.
Why Pre-Wire Coordination Makes or Breaks a Smart Home Build
Most callbacks we get on remodels trace back to one thing: nobody planned the low-voltage scope before the walls closed. A homeowner decides months after move-in they want a wired camera over the garage, and now someone’s fishing cable through a finished ceiling.
Pre-wire is cheap. Retrofitting is not. A run of Cat6 costs pennies a foot when the wall is open; the same run after drywall means patching, repainting, and a compromise on where the camera ends up. Builders who loop us in at the framing walk avoid that entirely.
What “Low-Voltage Pre-Wire” Actually Covers
Low-voltage pre-wire is every cable that isn’t 120V power: structured network cabling (Cat6/Cat6A), speaker wire, coax for TV locations, camera runs, and control wiring for shades, thermostats and lighting keypads. All of it terminates at a central distribution point — usually a rack in a garage, closet, or utility room — rather than daisy-chaining room to room.
On a typical custom home in our North County service area, that means home runs from every TV, access point, camera and keypad back to that central point — nothing shared, nothing looped.
The Room-by-Room Pre-Wire Checklist
Hand this list to your electrician with the plan set. It’s the minimum we ask builders to confirm before rough-in:
- Living/media room: two Cat6A runs behind the TV, plus speaker wire if theater or in-ceiling audio is planned.
- Kitchen and great room: one Cat6A run for a ceiling-mounted access point, plus in-ceiling speaker pre-wire if whole-home audio is in scope.
- Primary suite and bedrooms: one Cat6A drop per room, plus control wiring at shade locations.
- Home office: two Cat6A runs minimum — video calls and a wired workstation both want a dedicated line.
- Exterior and entry points: Cat6A to every camera location and the front door, plus a conduit stub to the garage for future expansion.
- Central rack location: a dedicated spot with power, ventilation and a data board — not a random shelf.
Mark every location on the electrical plan before rough-in — don’t leave it to whoever’s holding the cable spool that day.
Coordinating With Your Electrician: What Code Requires
Low-voltage and line-voltage wiring can share a job site, but not a raceway or stud bay without separation. NEC Article 800, governing communications circuits, requires at least 2 inches of separation from electric light, power, and non-power-limited fire alarm conductors, and prohibits combining communications and Class 1 power conductors in the same cable. That’s why we walk the framing with the electrician instead of guessing at their schedule — crossing that line means a re-pull, and re-pulls after insulation get expensive fast.
It’s also why builders bring in a licensed, dedicated crew instead of asking the electrician to add cable runs as a side task. A new construction low voltage contractor San Diego builders already trust knows these separation rules cold and shows up during framing, not after rough-in is signed off.
Cable Specs Worth Putting in the Contract
Not all “structured wiring” is equal, and the spec matters more than most builders realize until a homeowner wants gigabit speeds two years later. Cat6A outperforms standard Cat6 at longer runs and higher speeds, and it’s the grade we default to on every new build — nobody has ever asked us to downgrade cable already run inside a wall.
The ANSI/TIA-570 Residential Telecommunications Infrastructure Standard lays out grades for this decision — its Grade 2 spec calls for two Category 6A (or higher) runs plus one coax run at each outlet, close to our default on North County custom homes. Structured wiring San Diego new construction projects that follow this baseline rarely need a rewire before the next major renovation.
The Pre-Wire Mistakes That Cost Builders Money Later
We see the same mistakes repeat across job sites, and all of them cost less to avoid than to fix:
- Skipping the central rack location. Cables get pulled to a closet with no power or ventilation, and equipment ends up crammed somewhere it shouldn’t be.
- Sharing cable runs between devices. Daisy-chaining instead of home-running means one bad connection takes down multiple devices.
- Under-wiring rooms that get repurposed. A “flex room” with zero data drops becomes a home office with a hotspot in the corner.
- No conduit stubs for future expansion. Adding a camera later means fishing wire through finished walls instead of an empty sleeve.
Every one of these shows up on remodel calls where the homeowner is unhappy — and the original builder’s name is still on the house.
How to Choose a Low-Voltage Contractor for the Pre-Wire Scope
Not every subcontractor who does low voltage pre-wire new construction San Diego jobs treats it the same way. Ask three questions before signing one on: Are they licensed for low-voltage work in California (a C7 license)? Do they home-run every device to a central point instead of looping? And will someone show up at framing, not just final trim?
The Custom Electronic Design & Installation Association (CEDIA), the trade association for home technology professionals, recommends confirming rack locations and pathway conduit with the integrator before walls close — the step that gets skipped when pre-wire is treated as an afterthought instead of its own trade. Our crews are on-site at framing on every project, which is how we’ve built our working relationships with builders across North County.

Frequently Asked Questions
When should low-voltage pre-wire happen in the build schedule?
After framing is complete and inspected, but before insulation goes in — that’s the window where cable is easiest to run and still visible enough to verify against the plan set.
How much does low-voltage pre-wire add to a new construction budget?
It varies by square footage and how many rooms get data, camera and audio drops. Pricing for low voltage pre-wire new construction San Diego projects runs a fraction of the same scope done as a retrofit — we provide a written quote once we’ve reviewed your plan set and walked the site.
Do you work directly with our electrician and GC?
Yes. We coordinate with your electrician on separation and timing, and with your GC on scheduling — that coordination is part of the scope, not an extra.
Do you serve custom home builds outside Escondido?
Yes — see our service areas for the North County communities we work in, and our FAQs for more on how we scope new construction projects.
