Pre-Wire for New Construction

One trip at rough-in. No fishing through finished walls later.

Cat6A drops to every workstation and TV, speaker cabling to ceiling positions, smart-switch boxes with neutrals, PoE camera pulls, EV-ready conduit per Title 24, networking closet patch panel — all during framing, while the walls are still open.

What This Is

The 30 cables you wish were already there.

During rough framing, before insulation and drywall, every cable you might want for the next decade can be pulled at essentially the same labor as one cable. Cat6A to future TVs, 4K cameras, AP locations; CL2 / CL3 speaker wire to ceiling positions; neutrals at every switch box; PoE conduit to the doorbell; EV-ready conduit per Title 24. We come in twice — rough-in to pull and label, trim to terminate and commission.

Three years post-move-in is when homeowners discover what they should have pre-wired. Retrofit then runs 3-6x rough-in labor plus drywall patching. The line items worth front-loading: extra Cat6 drops per room, conduit chases between floors, networking closet with cable tray, EV-ready beyond minimum, speaker conduits to roomes that "might" become a media room.

Scope

What is included in a pre-wire scope.

Structured cabling, speaker pulls, smart-switch boxes, camera drops, networking closet, EV-ready — single bid, sequenced with the GC.

Cat6A Structured Cabling

Drops to every TV, every desk, every Wi-Fi AP location, every PoE camera position. Terminated at one end on a 24-port patch panel in the networking closet.

Speaker Cabling

CL2 / CL3-rated 14/2 or 14/4 to ceiling speaker locations — living rooms, primary bedroom, patio, kitchen. Pull plans coordinated with the AV scope.

Smart-Switch Boxes

Neutral wire to every switch box, single-gang or multi-gang depending on future controls plan. Pre-wired so Lutron Caseta / RadioRA install at trim is a one-for-one swap.

Doorbell + Camera Drops

PoE Cat6 to front-door doorbell location; Cat6 to each future camera position (front, back, garage, side gates). Outdoor pulls in conduit where required.

Networking Closet

24-port patch panel, dedicated 20A circuit, UPS slot, wall-mount or 12U rack. Cable trays / chases so future additions are pull-and-terminate.

CALGreen Title 24 EV-Ready

Dedicated 208/240V conduit from panel to garage / driveway, 40A reservation in load calc, future-charger box stubbed and labeled. Inspection-ready.

FAQ

Pre-wire questions, straight answers.

Prewiring installs planned cables and pathways while construction provides access to their routes. Open framing can reduce cable fishing and finish repair compared with the same work in closed walls, but the savings depend on the building and scope. More drops still require cable, supports, identification, termination and testing; five cables and fifty are not the same amount of work.

Use a coordinated endpoint and route schedule for desks, televisions, access points, cameras, speakers, entry devices and the equipment area. Identify cable types, mounting provisions, power responsibilities, labels, service slack, reserved pathways and tests. Coordinate EV charging infrastructure separately under the project’s applicable electrical and CALGreen requirements; a low-voltage cable plan does not establish EV compliance.

Coordinate route and mounting decisions with framing, electrical work and other trades before concealment. Define the rough-in inspection and documentation point, then schedule final terminations and testing around the actual finish sequence. The required visits and responsibilities should be written into the project schedule; do not assume every project fits a fixed two-visit installation.

There is no single count for every room. Leviton’s residential installer tip recommends at least two twisted-pair data cables, using at least Category 6, and two coaxial cables per cabled location. This is manufacturer planning guidance, not a universal code requirement or a maximum. Set the locations, cable category and count from the approved device plan, with ceiling access points, cameras and entry equipment planned separately. Additional cables have material, termination and testing costs.

The applicable requirement depends on occupancy, project type, permit code edition and local amendments. California’s 2025 CALGreen residential measures, effective January 1, 2026, describe EV infrastructure for new one- and two-family dwellings and townhouses within Section 4.106.4.1’s attached-private-garage scope: a listed raceway and reserved capacity and spaces for a minimum 40-ampere 208/240-volt branch circuit, with an exception when the qualifying circuit is installed initially. Multifamily and nonresidential projects follow different provisions; ADU and other exceptions require review. Confirm the approved project requirements rather than applying this residential example universally.

Cost depends on the approved endpoint count, route access, cable specification, pathways, mounting, equipment area, terminations and tests. Request an itemized project proposal with optional future provisions priced separately. Open framing can reduce access and restoration work, but extra cable is not free and no fixed retrofit cost multiple applies to every home.

Frequently asked project questions

Work through the difficult decisions.

Explore the causes, choices and practical next steps behind common project questions.

What should be settled before smart-home prewiring is covered by drywall?

Approve the concealed installation details before drywall: supported and protected cable, coordinated mounting points, service slack, labels and the agreed interim tests. Buying the final electronics can wait when these provisions are complete.

Is empty conduit enough to make new construction future-ready?

A usable future conduit needs accessible endpoints, an identified cable or connector envelope, suitable bends and pull points, and an accessible pull string or tape. Its size alone does not prove that a future cable can be installed.

Read the full guide: Empty Conduit Is Only Useful if a Future Cable Can Actually Be Pulled ↗
How can I verify new Cat6 wiring was installed properly?

Choose the acceptance test and its boundary before installation. A wire-map result, an application qualification and a category certification establish different things; require a labeled report that states which result was delivered.

Where should new-construction network equipment go?

Choose an accessible location sized for the actual equipment, power, ventilation, and service route. Plan wireless access-point locations separately; a convenient cable cabinet is not necessarily a good Wi-Fi location.
