How to Rewire Your Home without Hiring an Electrician


Rewiring a home can be a daunting task, but with proper planning and precautions, it is possible for a homeowner to rewire their house themselves and avoid the high costs of hiring an electrician. In this comprehensive guide, I will walk through the entire process of rewiring a home safely and legally without professional help.

Reasons to Rewire Your Home

There are several reasons you may want to rewire your home:

Dangers of Home Electrical Work

While DIY electrical work can save money, there are risks involved. Electrical dangers include:

Safety should be the number one priority when planning a DIY rewiring project. Proper precautions will allow you to rewire safely.

Rewiring Project Overview

Rewiring a whole house is a complex project that can generally be broken down into several key steps:

  1. Create a plan - Map out a detailed plan for running wiring to each room and location. Calculate electrical loads and circuit needs.

  2. Get permits - Obtain the necessary permits and schedule inspections before starting.

  3. Turn off power - Shut off electricity at the main breaker before touching any wires. Verify power is off.

  4. Remove old wiring - Take down outdated wiring but leave switches, outlets and devices in place.

  5. Install new wires - Run new wires through walls and ceilings to each location according to code.

  6. Connect wires - Carefully connect the new wires to existing outlets, switches and fixtures.

  7. Inspect and test - Have an inspector confirm work meets local codes and carefully test each circuit.

  8. Finish up - Add faceplates, covers and trim to complete the job. Turn power back on and test each circuit thoroughly.

Proper tools, safety precautions and attention to detail during each step is crucial for a successful rewiring project.

Making a Rewiring Plan

Careful planning is the most important part of any major home wiring project. Rushing in without a plan leads to frustration, mistakes and wasted time and money.

Here are key elements to include in your home rewiring plan:

Take time making a detailed plan before purchasing materials or starting work. This will save hiccups down the road.

Purchasing Materials

Once a plan is made, you can determine what materials will be required. Typical materials and hardware needed for rewiring a house include:

Take inventory before starting and purchase supplies and hardware in advance to avoid delay. Ensure everything is UL rated and up to local code.

Safety Gear Needed

Because electricity can injure or kill if mishandled, personal safety is paramount when DIYing electrical work. You should obtain and use the following safety gear:

Personal safety should be your top priority. Don't skimp on proper safety gear - it can save your life.

Obtaining Electrical Permits

Most jurisdictions require homeowners obtain an electrical permit before rewiring a home, even when doing the work themselves.

Electrical permits are important for several reasons:

Follow these steps when obtaining a rewiring electrical permit:

Getting a permit takes time so build this into your project schedule. It ensures your new wiring job meets local codes.

Turning Off Power

The most dangerous part of any electrical work is live wires. Accidental contact with live wires can injure or kill.

Follow these steps to fully disconnect power before starting a rewiring project:

Working on live wires should never be attempted. Verify power is completely off before touching any wiring to avoid fatal shocks.

Removing Old Wiring

With power disconnected, you can start removing outdated wiring. Follow these safe practices when taking out old wiring:

Work methodically and labeled wires as you remove them. Take photos of complicated junctions before disconnecting anything. The old wiring will provide a map for running new circuits.

Running New Wiring

Once old wiring is removed, the real work begins - running new wires for rewiring the entire house. Follow these tips when running new wires:

Take it slowly and be careful pulling wires. Leaving plenty of extra length is better than wires coming up short.

Connecting New Wires

Once new wires are run from the panel to all locations, it is time to start connecting switches, outlets and fixtures.

Use the following process when connecting wires:

Double check all connections are tight and correct. Bad connections can lead to shorts, fires and shocks down the road.

Inspections and Testing

With all new wiring installed and connected, your rewiring project is nearly complete. Next comes the final but very important steps of inspections and testing.


Schedule required inspections through your local building department based on the permit requirements. Typical inspections include:

Only upon passing required inspections can your new wiring be approved for use. The inspectors are there to catch any mistakes and ensure your safety.

Testing Circuits

Thoroughly test each circuit prior to closing up walls and ceilings.

Follow this process when testing circuits:

Take the time to methodically test each circuit. Catching flaws now prevents issues down the road after drywall is up.

Completing the Project

Once all inspections are passed and circuit testing is complete without issues, you're ready to wrap up the project.

With all these steps complete, you can turn everything back on and enjoy your newly rewired home! Take pride in the money you saved doing this major electrical project safely yourself.


While rewiring an entire home is challenging, this guide has provided you the key planning steps, safety advice and installation best practices to complete a successful DIY rewiring project without hiring an electrician.

Pay close attention to safety, research local codes thoroughly, take the job slow, double check all your connections, and call for inspections at the right times. With diligence and care, you can safely rewire your home and gain invaluable skills in the process.
