How Much Does Rewiring a House Cost in Los Angeles? [2025 Data]

Outdated wiring in your Los Angeles home may need to be replaced to handle modern electrical loads and prevent safety hazards, which often means rewiring your house. This job requires a local licensed electrician and costs an average of $2,509, with most homeowners spending between $773 and $4,304. We recommend arranging for an estimate to learn the cost of your specific wiring project and consider the factors affecting your LA home. 

Rewiring a House Cost Factors in Los Angeles

The cost of rewiring a house depends on several key factors about your home and the type of rewiring needed. Expect to discuss these topics with your electrician as you prepare to get your estimate. 

Home Size

The size of your home is the single most important factor for a full rewiring. The more rooms and circuits, the more wiring needs to be replaced. Start by estimating based on square footage: Complete rewiring costs around $2 to $4 per square foot. 

Materials

While home wiring is standardized, there are several different types, which your electrician will choose for you. Wiring that requires extra protection, like protection against heat and fire damage, will cost more. California electricians may recommend heat-protection materials due to the advanced risk of fire in Los Angeles.

Home Age

Older homes typically need more work to replace outdated variants of wiring, such as aluminum wiring or knob-and-tube wiring in houses that haven’t been upgraded for decades. The older the wiring, the more complete the rewiring project will be. Additional work may be required to bring your home’s wiring system up to current local and state electrical codes.

Accessibility

Home wiring isn’t always convenient to access. Electricians may need to use specialized hooks to reach some wiring, which can add to the labor costs. Depending on the home, cutting into drywall may be required, which will increase your labor and materials costs. 

Repairs and Clean Up

You can expect to spend up to $500 for post-project cleanup, depending on the electrician’s fees. This is often listed as part of the estimate without much fanfare. Contractors usually cover simple site preparation, but homeowners should prepare the area by moving furniture, securing valuables, and minimizing the risk of dust or damage. 

Government Incentives

Certain government programs may be able to offset the high costs of rewiring. Los Angeles has assistance programs like LIHEAP (Low Income Home Energy Assistant Program) that offers programs and rebates to homeowners who qualify for assistance.

Electrician Pro Costs in Los Angeles

Rewiring deals with serious hazardous voltage, so it requires a certified electrician to handle. If you are looking for a labor estimate for the project, there are several important things to keep in mind. 

Licensing and Insurance

Electricians must be licensed and insured to rewiring a house in LA. During the hiring process, verify the local electrician’s certification and insurance, and be sure they have prior experience with replacing home rewiring systems that match yours.  

Hourly Rates and Taxes

Labor costs are especially important for a rewiring project, since it often lasts up to a week. In Los Angeles, hourly electrician rates are $35 to $50 per hour, but rewiring is a more advanced project, often requiring expert or multiple electricians, so you can expect hourly rates to be higher. For a larger project like rewiring, electricians may offer a lump sum price that will cover labor. 

Tipping

Tipping electricians is not expected or required. However, you can choose to tip 10% to 15% for exemplary work to support your local electrical team. 

Permits

Electricians handle acquiring the required electrical permits from the City of Los Angeles, but homeowners will cover the cost, plus the price of electrical inspections. You can expect to pay around $100 to $200 for rewiring permits and an electrical inspection afterward.

Does a New Wiring Increase Home Value?

Rewiring is an important project to complete prior to listing your LA home for sale. A home with old or defective wiring may not sell unless those costs are worked into the buying price. Luckily,  rewiring your home can offer a great return on your investment, especially if you’re replacing knob and tube wiring or other outdated, hazardous components.

An upgraded electrical system improves safety, ensures local code compliance, and supports modern energy-efficient appliances and EV capabilities, which is popular in LA. A complete home rewire improves your home’s function and can be a key factor in successful inspections and home appraisals across Los Angeles.
