Copper Wire Theft: Why It’s Rising in Southern California and How to Protect Your Property

The recent increase in copper wire theft has led to widespread outages and safety concerns across Southern California communities. AT&T reported 2,200 incidents in California in 2024, a sharp rise from 71 in 2021, according to CNN. Last year, more than 37,000 streetlight repair requests were made in Los Angeles, largely due to copper wire theft. One major crime site, the Sixth Street Bridge, has lost seven miles (38,000 feet) of copper wire over several years, totaling $2.5 million in damage. 

 

Why are thieves targeting copper, and what does this mean for your property? Below, we’ll discuss the rise of copper wire theft in California, where thieves are stealing copper wire, and what you can do to protect your home or business. 

Why Copper Wire Theft Is a Growing Problem

The primary reason copper wire theft has increased over the past few years is the consistent rise in copper prices. According to Fidelity, several growth industries—including electric vehicles, AI, data centers, and renewable energy—require massive amounts of copper. With demand high and copper deficits projected in 2026, the price has jumped to more than $13,000 per tonne in recent months. 

 

In October 2025, Governor Newsom signed legislation in response to copper wire theft and vandalism. AB 476 is designed to strengthen theft prevention, hold the scrap metal industry accountable with greater penalties and reporting requirements, and protect infrastructure. However, since enforcing these new regulations takes time, criminals have continued to strike successfully. 

How Copper Wire Theft Impacts Homes and Businesses

Copper wire theft is costly and poses safety risks for homeowners and businesses. A significant number of power outages in Los Angeles have been caused by copper wire theft, resulting in dark streets and safety concerns for residents. These crimes have also disrupted schools and essential services.

 

CNN reported more than 15,000 attacks nationwide on domestic communication networks from June 2024 to June 2025. With phone lines and internet connections down and emergency services disconnected, businesses and residents are increasingly vulnerable. 

 

For homeowners, stolen copper may require not only replacing wire but also rebuilding entire systems, such as a damaged HVAC or irrigation system. This can total up to $10,000, depending on specific factors. Likewise, individual businesses have reported major losses, with some exceeding $100,000 in a single incident. Copper wire theft has left some buildings without power for extended periods.

 

Perhaps the most vulnerable properties, construction sites for new homes and home remodeling projects, are often targeted, with theft incidents creating additional expenses and delaying project timelines. This has been particularly evident on rebuilding sites affected by the 2025 Palisades and Eaton wildfires, according to a detective interviewed by CNN. 

How Thieves Steal Copper Wire in Residential Areas

Knowing how thieves operate can help you better protect your property. Criminals have developed sophisticated methods to target homes and businesses across Southern California. 

 

Copper theft, along with many other forms of criminal activity, typically occurs at night or on weekends, when suspicious activity is less noticeable. Copper used in residential properties includes wiring for air conditioners, outdoor electrical panels, and exterior light fixtures. Thieves may use bolt cutters or other tools to access the wires, then later burn off the insulation, leaving the bare copper wire for sale. 

 

Along with residential properties, construction sites are especially vulnerable. Any exposed wiring during a renovation project can attract thieves, particularly on unmonitored properties.

How to Prevent Copper Wire Theft on Your Property

Even with copper theft incidents so prevalent, there are effective steps you can take to protect your property from copper thieves. A layered security approach that combines multiple strategies provides the best protection. Here are our top strategies:

 

• Motion-sensor lights: Motion-detecting security lights are known to deter criminals. Install these devices around your most vulnerable outdoor areas.
• Surveillance cameras with local alarm monitoring: A security camera system is not enough to deter property threats. While it’s important to capture suspicious activity, adding a fast-response local monitoring team can ensure law enforcement is dispatched to the property immediately upon threat detection. Night Shield, Post Alarm’s proprietary service, uses AI technology to detect potential threats and alert live video monitoring agents for immediate verification and response. 
• Temporary security for construction sites: Thieves targeting construction sites put valuable building and home materials at risk. From temporary construction monitoring and Patrol response to prewiring and permanent system installation, Post Alarm helps to secure your property and keep rebuilding projects on track.
• Protection for your outdoor systems: Worried about your copper-filled outdoor systems? Use locked cages, enclosures, or fencing for air conditioning units, HVAC systems, or electrical panels. Make sure to secure all tools and ladders when not in use. 
• Community support: You can enhance safety in your community by participating in neighborhood watch programs or simply sharing information about suspicious activity with your neighbors. If you have a neighborhood patrol service, report any suspicious activity to your local agent, as well.
