How Much Does It Cost to Run Low-Voltage Wire?

If you’re planning a home renovation, installing a new security system, or upgrading your office network, you might be wondering: how much does it cost to run low-voltage wire? The answer depends on several factors — from wire type and distance to labor costs and project complexity.

This guide breaks down everything you need to know about low-voltage wiring installation costs, including average price ranges, what affects the total cost, and how to plan your project efficiently. Our experienced low voltage contractors in Los Angeles provide affordable wiring solutions for both residential and commercial projects.


What Is Low-Voltage Wiring?

Low-voltage wiring is any electrical wiring that carries 50 volts or less. It’s commonly used for systems like:

  • Security cameras and CCTV systems
  • Doorbells and intercoms
  • Internet and phone networks
  • Audio and video systems
  • Thermostats and smart home devices
  • Landscape lighting

Unlike standard electrical wiring (120V or 240V), low-voltage wiring is safer to install and doesn’t require the same heavy conduit or power regulation. However, it still needs proper planning, quality materials, and professional installation to perform reliably.


Average Cost to Run Low-Voltage Wire

In general, low-voltage wiring costs between $2 and $6 per linear foot, depending on the complexity of the job. Here’s a breakdown of typical pricing:

Project TypeAverage Cost per FootAverage Total Cost
Basic Ethernet or phone wiring$2 – $3$200 – $600 per room
Security camera system wiring$3 – $5$500 – $2,000 total
Home theater or speaker wiring$3 – $6$400 – $1,200 per room
Whole-home smart system$4 – $8$1,500 – $4,000+
Outdoor/landscape lighting wiring$2 – $4$300 – $1,000 total

These prices include materials and labor, but can vary based on location, cable type, and accessibility.


Factors That Affect Low-Voltage Wiring Costs

Every project is unique. Here are the main factors that determine your total cost:

1. Type of Cable Used

Different cables come with different price points:

  • CAT6 Ethernet cables – For high-speed networks ($0.30–$0.50/ft)
  • Coaxial cables (RG6) – For TVs and cameras ($0.20–$0.40/ft)
  • Speaker wire – For audio setups ($0.25–$0.60/ft)
  • Fiber optic cables – For enterprise or long-distance connections ($1–$2/ft)

2. Building Type and Layout

Running wire in new construction is usually cheaper because the walls are open. In finished homes or offices, installers must fish cables through walls and ceilings, increasing labor time and costs.

3. Labor and Installation Fees

Professional low-voltage installers typically charge $50–$100 per hour. Jobs that require extra tools (like wall fishing or trenching for outdoor cables) may cost more.

4. Distance and Number of Connections

Longer runs and more devices mean more wire, connectors, and wall plates — all of which add to the total price.

5. Permits and Code Compliance

In some areas, low-voltage wiring still needs to follow local electrical codes. Professional installers will ensure compliance with California Title 24 and other regional standards if you’re in the state.


DIY vs. Professional Installation

You can run some low-voltage wires yourself if you’re comfortable with basic electrical work. However, professional installation ensures that:

  • Cables are correctly terminated and labeled
  • Signals remain strong with minimal interference
  • Fire safety and code compliance are met
  • The final setup looks clean and organized

Hiring a licensed low-voltage contractor can save you time, prevent costly mistakes, and provide a warranty on your system. Choosing the right wire gauge is essential to avoid voltage drop — learn how to determine the correct low voltage wire size for your setup.


Tips to Save Money on Low-Voltage Wiring

Here are a few ways to reduce costs without sacrificing quality:

  • Bundle installations – Combine multiple systems (Wi-Fi, cameras, and audio) during one project.
  • Use structured cabling – CAT6 or CAT6a cables can serve multiple functions for years.
  • Plan for the future – Add extra conduits or junction boxes for expansion later.
  • Get multiple quotes – Compare prices from at least three licensed installers.

When to Upgrade Your Wiring

If your home or office still uses CAT5 cables, old coaxial lines, or inconsistent wireless connections, it’s time for an upgrade. Modern CAT6 or fiber wiring provides faster speeds, stronger signals, and better compatibility with today’s technology — from streaming devices to smart home hubs.
