Protecting LA Tenants from Power Surges: A Guide for Property Managers
It usually starts with a simple call from a tenant, “My microwave just stopped working,” or “The lights in the hallway keep flickering.” What looks like a minor inconvenience might actually signal a deeper issue: a power surge that traveled through your building’s electrical system.
Power surges are one of the most common and costly electrical problems in Los Angeles. They happen in an instant, often without warning, and they don’t just affect electronics, they can damage appliances, weaken wiring, and shorten the lifespan of panels and breakers. In multi-unit properties, that means multiple tenants can experience damage at the same time, creating disputes, insurance claims, and safety concerns.
With Los Angeles’s aging infrastructure and frequent grid fluctuations, property managers are seeing an increase in surge-related issues. High temperatures, heavy summer demand, and even maintenance work by LADWP can cause voltage spikes that ripple through entire neighborhoods.
Fortunately, these risks are preventable. By investing in professional surge protection and maintaining your property’s grounding system, you can safeguard your tenants, reduce liability, and protect your building’s electrical integrity for years to come.
What Causes Power Surges in Los Angeles Properties
Power surges occur when voltage levels suddenly spike beyond the standard 120 volts that most household and commercial systems are designed to handle. Even a brief spike lasting less than a second can overload sensitive electronics and cause cumulative damage to wiring and breakers. In Los Angeles, these events happen more often than many property managers realize.
Grid Instability During Peak Demand
During heatwaves, Los Angeles’s electrical grid operates near maximum capacity. When demand spikes from thousands of air conditioning units running simultaneously, even small fluctuations in supply can send voltage surges through utility lines. When power is restored after a rolling blackout or transformer maintenance, that surge often hits first at commercial properties and apartment complexes.
Equipment and Appliance Cycling
Large equipment like HVAC compressors, elevators, and refrigeration systems draw high amounts of current when they start up. That surge can send voltage fluctuations through shared circuits, especially in older buildings where load distribution isn’t balanced. Over time, these small, repetitive surges weaken wiring insulation and shorten the lifespan of connected devices.
Transformer or Utility Faults
Power surges also occur when transformers malfunction or when LADWP or Southern California Edison perform maintenance nearby. These brief but powerful spikes can affect entire blocks of properties. Because underground cables carry electricity directly from transformer vaults to service panels, surges can reach tenants’ units within milliseconds.
Construction and Nearby Work
In a dense city like Los Angeles, commercial and residential construction is constant. Nearby excavation or utility work can disrupt underground electrical lines or grounding systems, introducing temporary surges that travel through multiple properties.
Lightning and Environmental Causes
Although lightning is rare in Southern California, even distant strikes can cause momentary voltage spikes across the grid. Static discharge, poor grounding, or water intrusion into exterior panels can also contribute to smaller, localized surges.
Each of these causes is unpredictable, but the damage they cause is not. Proper surge protection acts as a barrier between your property’s electrical infrastructure and the grid, ensuring tenants and systems stay safe when the next surge occurs.
(For reference, see the LADWP Power Quality Guidelines and NFPA Power Surge Safety Information for official recommendations.)
The Real Cost of Ignoring Surge Protection
When property managers think about electrical maintenance, surge protection rarely makes the top of the list. Yet failing to address it can lead to some of the most expensive and disruptive problems a building can face. Surges don’t just damage tenant electronics, they quietly degrade your entire electrical infrastructure over time.
Damage That Goes Beyond Tenant Appliances
Every power surge, no matter how small, leaves a mark. The first signs are usually minor: LED lights that flicker, outlets that feel warm, or equipment that suddenly stops working. Inside your system, however, surges are slowly weakening insulation, stressing circuit boards, and reducing the life expectancy of your panels and breakers.
Over time, these repetitive events can lead to permanent wiring damage or even electrical fires. That’s why NFPA and LADBS both emphasize surge protection as part of a comprehensive electrical safety strategy for multi-unit properties.
Tenant Claims and Liability
When surges destroy appliances, computers, or security equipment, tenants often expect property managers or owners to cover the cost of replacement. Even if the building isn’t directly responsible, these disputes can create frustration and erode tenant trust.
For commercial tenants, the stakes are higher. A single surge can disable POS systems, damage inventory freezers, or corrupt business data, all leading to lost income. Without documented surge protection measures, insurance carriers may question whether the property owner took reasonable steps to prevent the incident.
Insurance and Legal Risks
Many property insurance policies require evidence of surge protection or electrical maintenance as part of coverage verification. If a claim is filed after surge-related damage, insurers may reduce or deny coverage if protection wasn’t installed.
This is especially important in Los Angeles, where high summer demand and frequent grid switching make surges inevitable. Having a professionally installed surge protection system gives you not only real safety but also clear documentation that your property meets modern standards for risk prevention.
The Cost of Downtime
Even minor outages can create significant disruptions for tenants. For apartment residents, that might mean losing air conditioning or internet access. For businesses, downtime means lost customers and revenue. Surge protection helps prevent these interruptions by shielding systems from the sudden voltage spikes that cause tripped breakers, burnt wiring, and equipment failure.
The reality is simple: paying for surge protection today costs far less than paying for repairs, lost equipment, and frustrated tenants later.
How Surge Protection Systems Work
A surge protector acts like a safety valve for your electrical system. When voltage spikes above safe levels, the protector diverts that excess energy safely into the ground before it reaches your building’s circuits and devices.
Whole-Building vs. Plug-In Protection
Many property managers are familiar with plug-in surge strips used for computers or entertainment systems, but these offer only limited protection. They defend a few outlets, not the building as a whole.
Whole-building surge protectors, installed at the main electrical panel, shield every circuit in the property. When installed correctly, they protect not only tenant outlets but also shared systems like lighting, HVAC, elevators, and building security.
The best approach is layered protection: a primary surge device at the service entrance, and localized protectors for high-value tenant equipment.
Integration With Electrical Panels
At RG Electric, our licensed electricians install surge protection directly at your property’s main service panel or sub-panels. These units monitor incoming voltage from the grid and activate automatically when a surge is detected. The device redirects excess energy to the grounding system, where it dissipates harmlessly.
Proper installation is critical. Surge protectors must be rated for the building’s service amperage, panel type, and grounding condition. A poorly installed or undersized device can leave parts of your system exposed. That’s why surge protection should always be handled by a licensed Los Angeles electrician familiar with LADBS and NEC standards.
Protecting Shared Systems
Surge protection benefits go beyond individual tenant spaces. It safeguards shared electrical systems like gate motors, parking lot lighting, elevators, and fire alarms, equipment that’s both expensive and essential. By preventing voltage spikes from reaching these systems, you avoid costly breakdowns that can affect every resident or business in your property.
How It Pays for Itself
The average surge protection installation costs a fraction of a single insurance deductible or equipment replacement. Over time, it extends the life of panels, breakers, and wiring, reducing long-term maintenance costs and improving energy stability across your property.

Practical Steps Property Managers Can Take Right Now
Even before installing surge protection, there are several simple steps Los Angeles property managers can take to reduce risk and prepare their buildings for a safer, more stable electrical system.
1. Schedule a Professional Surge Inspection
If your building has never had its panels checked for surge protection, start with an inspection. A licensed electrician can verify whether devices are installed, test grounding continuity, and identify weak points in your system.
At RG Electric, we perform these inspections quickly, with minimal tenant disruption, and provide a clear written report outlining any needed improvements.
2. Educate Tenants on Safe Electrical Use
Tenants play an important role in surge prevention. Encourage them to unplug sensitive electronics during storms, use quality surge strips for computers and entertainment systems, and avoid overloading outlets with adapters or daisy-chained cords.
Including these reminders in tenant welcome packets or newsletters shows you’re proactive about electrical safety and helps prevent unnecessary damage from everyday usage.
3. Combine Surge Protection With Seasonal Maintenance
Surge protection works best when paired with regular electrical maintenance. Fall and spring inspections are ideal times to test breakers, confirm proper grounding, and inspect outdoor panels for corrosion or moisture intrusion.
Combining these services saves time and reduces the chance of downtime during peak energy seasons. You can learn more about preventive maintenance on our Commercial Electrical Services in Los Angeles page.
4. Keep Documentation for Insurance and Compliance
Maintaining a record of surge protection installations, inspection dates, and maintenance reports is essential. This documentation proves to LADBS inspectors, insurance carriers, and tenants that your property complies with current safety standards.
RG Electric provides digital and printed documentation after every installation, making it easy to reference when needed.
5. Plan for Future Expansion
If your property is planning upgrades such as EV charger installations or new HVAC equipment, now is the time to verify that your surge protection system can handle increased load. As demand grows, so does the importance of layered protection. RG Electric can integrate surge protection into larger projects to ensure long-term reliability and compliance.
