How to Install a Ceiling Fan Without Existing Wiring – A Step-by-Step Guide

Installing a new ceiling fan can help improve airflow and comfort in a room. But what if there is no existing wiring or ceiling light fixture already in place? Running new wiring may seem complicated, but with proper planning and safety precautions, you can install a ceiling fan without existing wiring.

In this comprehensive guide, I’ll walk through the complete process of installing a new ceiling fan in a location without any existing wiring or fixture.

Planning Your Ceiling Fan Installation

Before getting started, take time to plan the fan installation project:

  • Choose the location – Pick a spot with adequate structural support for the fan weight. Avoid installation directly below existing cables or ductwork.

  • Check attic access – Ensure you have ready access to the attic space above the installation location. This makes running new wiring much simpler.

  • Inspect power source – Verify there is an accessible power source like a light switch or outlet box to tap into for the new wiring.

  • Choose mount type – Decide if you want a flush mount or downrod style ceiling fan for the space.

  • Get needed supplies – Make a list of all required materials and tools for installation before starting work.

Safety Tips for Wiring a New Ceiling Fan

  • Turn off power at the main breaker before doing any electrical work.
  • Have a helper assist you with the installation.
  • Use a fiberglass ladder when working with electrical wiring.
  • Confirm power is off by testing wires with a non-contact voltage tester.
  • Follow all local building codes and permit requirements.
  • Use exact replacement wires and parts. Never substitute.

Electrical Permits

Installing new wiring for a ceiling fan generally requires obtaining an electrical permit from your local building department. Requirements vary by location, but typically involve:

  • Filling out an application with project details.
  • Providing diagram of planned electrical work.
  • Paying a permit fee.
  • Scheduling inspections before, during, and after installation.

What You’ll Need


  • Voltage tester
  • Hammer drill
  • Fish tape
  • Wire strippers
  • Screwdrivers


  • 14/3 or 12/3 NM cable
  • Ceiling fan-rated electrical box
  • Cable clamps or staples
  • Wire nuts
  • 1-gang box (if adding switch)

Step-by-Step Installation

Follow these steps to install wiring and mount a new ceiling fan:

1. Turn Off Power

Shut off power at the main breaker panel before beginning any electrical work. Use a non-contact voltage tester to confirm power is off.

2. Install New Electrical Box

  • Mark exact fan location on ceiling.
  • Drill holes for electrical box supports aligned with ceiling joists.
  • Mount sturdy fan-rated metal electrical box between joists.

3. Run New Wiring

  • Route cables from power source through attic and over to fan box.
  • Secure cable every 4.5 ft with clamps or staples.
  • Leave 12-18 inches of extra cable at fan box.

4. Connect Wires

  • Strip sheathing and connect white (neutral), black (hot), ground, and extra for fan/light control if adding switch.
  • Attach wires securely with wire nuts.

5. Mount Ceiling Fan

  • Attach ceiling fan mounting bracket to box.
  • Lift fan into place and connect wires per fan manual instructions.
  • Attach fan blades and light kit.

6. Install Wall Switch (Optional)

  • Fish 14/2 cable from light switch box to ceiling box.
  • Connect wires to provide independent fan/light control.
  • Install 1-gang box and wall switch.

7. Complete the Job

  • Do drywall patching and repainting if needed.
  • Have work inspected by building department.
  • Turn power back on and test fan operation.

Finding an Existing Power Source

Locating an existing power source is needed to tie into when adding a new ceiling fan circuit. Potential options include:

  • Light switch – Turn off power and remove switch. You can tap into the hot and neutral wires inside the switch box.

  • Outlet – Remove outlet cover and tap into the hot and neutral wires. Be sure to turn off the circuit breaker first.

  • Junction box – Often found in attics and can be used to splice into existing wiring.

Always use caution when working with live electrical wires. Turn off power and verify it’s off with a voltage tester before doing any work.

Removing the Existing Light Switch or Outlet

Once you’ve turned off power to the circuit at the breaker, you can remove the existing switch or outlet:

  • Unscrew and remove cover plate.
  • Unscrew and detach the switch or outlet.
  • Carefully disconnect all wires from the device.
  • Remove existing switch/outlet mounting screws.
  • Set aside wires and old switch/outlet for reinstallation later.

Fishing the New Wiring

To route the new wiring from the power source up to the ceiling fan box, you’ll need to “fish” the cables up through the wall cavity:

  • Feed fish tape up from switch box through top plate into attic space above.
  • Attach NM electrical cable to end of fish tape.
  • Pull fish tape back through wall, dragging new cable along with it.
  • Leave plenty of extra cable at both boxes.

Wiring the Ceiling Fan

Follow the ceiling fan manual for manufacturer-specific wiring instructions. But in general:

  • Connect the white (neutral) wires together with a wire nut.
  • Connect the black (hot) wire to the black and blue fan wires.
  • Connect the grounding wires (green or bare) together.
  • Install included pull chain extensions for fan and light controls.

Control Options for New Ceiling Fan

You have a few options for controlling power to your new ceiling fan and light:

Pull Chains

The most basic option are pull chain switches directly on the fan. This lets you turn the fan and light on and off manually. No new wall switch is required.

1-Switch Wiring

Run a 14/2 cable from an existing light switch to the ceiling box. This allows turning the fan and light on and off together.

2-Switch Wiring

Run a 14/3 cable from a new 2-gang box to the ceiling box. Connect the red wire to the fan and black to the light. Install two separate switches for independent fan/light controls.

Installing a New Wall Switch

If you opted to add a wall switch, install it once all wiring is completed:

  • Install new 1-gang electrical box if more control is desired.
  • Secure the new switch inside the electrical box.
  • Connect the hot source and switch leg wires to the switch.
  • Attach the cover plate.

Finishing Touches

To complete the new ceiling fan installation project:

  • Patch drywall holes from electrical boxes and fishing cable.
  • Paint repaired drywall to match existing.
  • Have final electrical inspection done by building department.
  • Turn power back on at the breaker and test fan operation.
  • Attach fan blades and light fixtures.

Reasons to Call An Electrician

While the process of installing a ceiling fan without existing wiring is very doable for some homeowners, it’s best to call a professional electrician if:

  • You don’t feel completely comfortable working with electrical.
  • Local codes require certified electricians for new wiring.
  • Accessing the installation area is difficult.
  • The ceiling or attic space lacks needed mounting points.
  • Complications arise with knocking out drywall or accessing wires.

Cost to Install a Ceiling Fan Without Existing Wiring

On average, expect to pay $150 to $300 for electrical work and labor to wire and install a new ceiling fan without existing wiring. The exact cost depends on:

  • Complexity of running new wiring to point of installation
  • Accessibility of ceiling space for routing wires
  • Type of mounting box required
  • Adding a switch for separate fan/light controls
  • Labor rates in your geographic area

Hiring an experienced and licensed electrician ensures the work is done properly and safely. They have the knowledge to overcome potential electrical challenges and wire the fan correctly.


The ability to install ceiling fans in rooms without existing wiring or fixtures opens up many new possibilities. By taking the proper safety steps and following electrical code requirements, the process of running new wires and adding a ceiling fan can be manageable as a DIY project. But for many homeowners, calling a professional electrician is the best way to guarantee safe and legal installation.
