How much does smart home wiring cost in Virginia?

Smart home wiring has no standard price, in Virginia or anywhere else, because the job can be anything from one cable to a thermostat to dozens of network, camera and speaker runs plus new outlets and switch boxes. What you pay is set by how many runs there are, whether the walls are open or finished, how much line-voltage electrical work comes with the cable, and whether a permit is needed. Get itemised written quotes and compare them run by run.

This page explains what drives the price and how to read a quote. The work itself is for licensed pros.

What drives the cost

Open walls or finished walls. This is usually the biggest factor. During new construction or a gut remodel, a cable run is a short job across open framing. In a finished house, each run means fishing cable through walls, attics and crawlspaces, cutting access holes and patching drywall afterwards. Ask whether patching and painting are in the quote or left to you.

The number and length of runs. Quotes are often built per run or per drop (one cable from the central location to one wall plate or device). A two-storey house with the central wiring spot in the basement means longer runs to upstairs rooms than a one-level house.

Cable type. Network cable, coax, speaker wire, thermostat cable and camera cable are priced differently, and higher-grade network cable costs more per foot. A low-voltage firm will tell you which it proposes and why.

Line-voltage work. Smart devices still need house power. New outlets for cameras, access points and a central network closet, a neutral at switch boxes for smart switches, and power for a doorbell transformer are electrical work. These items can add as much as the cable itself, and they bring a permit.

The central wiring location. An enclosure or wall panel where every cable ends, with labelled terminations and a nearby outlet, adds materials and time.

Devices and setup. Some quotes include the smart switches, cameras or speakers and their setup; others are wiring only. Make sure both quotes you compare include the same things.

Workarounds that can lower the bill

Some smart devices are designed to avoid new wiring. For a smart thermostat with no C wire, ecobee sells a Power Extender Kit for homes with at least four wires at the thermostat, as an alternative to running a new wire.^[9] For switch boxes without a neutral, Leviton sells no-neutral smart dimmers and switches for older homes, which work through its Wi-Fi bridge.^[10] Ask the electrician whether a device choice like that removes a line item before you pay to open a wall.

Permits and what they cost

Virginia's Uniform Statewide Building Code says a permit is required before work on electric wiring begins,^[1] but no permit is needed for wiring and equipment that operates at less than 50 volts, is for broadband communications systems, or is for monitoring or automation systems in dwelling units,^[1] unless it runs in a plenum, goes through fire-rated or smoke-protected construction, or is part of a fire alarm, fire detection or access control system.^[1] The code also says replacing a switch, dimmer or control switch in a house is ordinary repair that needs no permit application.^[1]

Localities apply the same rule. Prince William County lists installing low-voltage wiring under 50 volts, such as a door bell or security system, as work that needs no permit, while installing a new electrical circuit, fixture or receptacle does.^[2]

So a cable-only job may carry no permit fee at all, while one that adds circuits, outlets or fixtures will. Fees vary by locality. As one example, Montgomery County's fee schedule, effective June 2018, charges $0.03 per square foot of gross building area, with a $45 minimum, for an electrical trade permit,^[3] plus a 2% state levy and a 2% technology fee (minimum $10).^[3] Ask your own county or city for its current schedule, and ask each bidder whether the permit is included.

Who you are paying, and what their licence covers

Virginia licenses low-voltage cabling as electronic/communication service contracting (ESC), covering computer cabling, sound systems, data and network installation, television and cable TV wiring and other systems that operate at 50 volts or less.^[5] An electrical contractor's licence also covers it, and the Board requires a master tradesman licence for an electrical contractor.^[4]

The licence class should fit the size of the job. A Class C contractor licence covers a single job worth over $1,000 but less than $30,000,^[4] and a Class B licence covers single jobs of $30,000 or more but less than $150,000.^[4] A whole-house package can cross that line.

Security work is licensed separately: a business that installs alarms or security cameras for a homeowner needs a private security services licence from the Virginia Department of Criminal Justice Services.^[8][6][7]

What to ask for in a written quote

A good quote lists every cable run by room and purpose, the cable type for each, the central wiring location and what is in it, each new outlet, switch box or circuit, who pulls the permit and whether its fee is included, drywall repair, labelling and the as-built documentation you receive.

When to call a licensed pro

Call before the walls close if you are building or remodelling, because that is the cheapest time to wire; see whether to prewire during a remodel. In a finished house, call when a device needs power or a neutral where there is none, when a smart switch will not fit or work in an old box, or when you want cameras and access points wired rather than battery-powered. Get at least two itemised quotes and check each contractor's licence. For what the job covers, read what prewiring for smart devices involves.
