Electrical Infrastructure Upgrades for Apartment Properties
As an apartment owner or property manager in the Greater Sacramento area, you are likely aware that the electrical infrastructure of your buildings is under more pressure than ever before. In the 1970s and 80s, an apartment unit only needed to power a few lights, a refrigerator, and perhaps a small television. Today, your tenants are running high-powered gaming computers, multiple air conditioning units, electric vehicle chargers, and a suite of high-end kitchen appliances.
At TNT Electric, we specialize in Multi-Family Panel Upgrades. We help property owners transition from dangerous, obsolete electrical systems to modern, high-capacity infrastructure that meets California’s stringent safety codes and satisfies the increasingly picky demands of insurance providers.
The “Insurance Crisis” and Obsolete Panels
The number one driver for panel upgrades in Sacramento today isn’t just safety—it’s insurability. Many insurance carriers are now conducting “underwriting inspections” and flatly refusing to renew policies for buildings equipped with specific brands of electrical panels that have been deemed fire hazards.
The “Big Three” Hazardous Panels
If your complex was built between 1950 and 1990, there is a high probability you have one of these three brands. If you do, your building is at risk.
- Federal Pacific Electric (FPE) Stab-Lok:
These are notorious in the industry. Testing has shown that FPE breakers often fail to trip when a short circuit or overload occurs. This results in the wire melting and catching fire while the breaker remains in the “on” position.
- Zinsco / Sylvania-Zinsco:
These panels have a design flaw where the circuit breaker’s connection to the bus bar loosens over time, creating “arcing.” This causes the breaker to literally fuse to the bus bar, making it impossible to shut off the power in an emergency. - Challenger:
Often found in 1980s builds, these panels were discovered to have issues with overheating at the connection points, leading to a high rate of internal fires.
Why this matters for your bottom line: Beyond the risk of fire, having these panels can triple your insurance premiums or result in a total loss of coverage. Our Commercial Service Work team can provide a full audit of your complex to identify these hazards before they become a crisis.
The Benefits of Upgrading Your Multi-Family Infrastructure
Upgrading a 100-unit complex is a significant investment, but the Return on Investment (ROI) is multi-faceted.
Increased Property Value and "Saleability"
When it comes time to sell your multi-family asset, an outdated electrical system is a massive “red flag” for buyers during the due diligence phase. It often leads to heavy “credit” requests or buyers walking away entirely. A modern electrical system is a massive selling point that proves the building has been well-maintained.
Reduced Maintenance Overhead
Old panels are prone to “nuisance tripping.” This leads to constant Apartment Service Calls where your maintenance staff or an electrician has to reset breakers. Over time, these small service fees add up. Modern Eaton or Square D panels are designed for the high-demand loads of the 21st century.
Tenant Retention and Satisfaction
Nothing frustrates a tenant more than not being able to run their microwave and hair dryer at the same time. By upgrading to 100-amp or 125-amp service per unit, you provide the “power overhead” that modern tenants expect.
EV Readiness
California is leading the charge in Electric Vehicle adoption. To install EV chargers at your complex, you must have a robust main distribution board. Our Warehouse & Commercial Lighting experts often coordinate with our panel team to ensure your main service can handle the future addition of charging stations.
The TNT Electric Process: Minimal Tenant Disruption
We understand that the biggest fear property managers have is the logistical nightmare of a power shut-off. At TNT Electric, we have refined a “Multi-Unit Strike Protocol” that ensures the job gets done with surgical precision.
Phase 1: The Site Audit and Permitting
We don’t just guess. We conduct a unit-by-unit audit to determine wire gauge compatibility and current load. We then handle the entire permitting process with the City of Sacramento or Sacramento County.
Phase 2: Utility Coordination
One of the hardest parts of a panel upgrade is coordinating with the utility company. We handle all communication with SMUD or PG&E to schedule the “Disconnect / Reconnect” window. We strive to keep power outages limited to a single workday (usually between 8:00 AM and 4:30 PM).
Phase 3: The Install
Our teams work in pairs. While one team works on the Tenant Improvement style internal wiring, the other is at the main service board. This “parallel processing” allows us to finish units in record time.
Phase 4: Inspection and Safety Certification
Once the new panels are in, we coordinate with the local building inspector. We don’t leave the site until the stickers are signed and the power is safely restored to your tenants.

Multi-Family Upgrades FAQs
How much does it cost to upgrade an apartment panel?
Costs vary based on the number of units and the state of the existing wiring. However, when doing “bulk” upgrades, the price per unit drops significantly compared to a single-family home. We provide comprehensive bids that include all permits and utility fees.
Do I have to upgrade the wiring inside the walls too?
Not always. In many cases, we can “piggyback” the existing copper wiring onto a new, safe panel. If your building has aluminum wiring (common in the 60s and 70s), we use specialized Al/Cu connectors to ensure a safe transition.
How long does the power have to be off?
For a standard unit panel replacement, we typically have the power back on within 4 to 6 hours. For a Main Distribution Board (MDB) upgrade, it may take a full day.
Can this be done one unit at a time?
Yes. Many of our clients choose to upgrade panels during Tenant Improvement buildouts or when a unit becomes vacant.
Do you handle Federal Pacific, Zinsco, or Challenger panel replacements?
Yes. These are three of the most common hazardous panel brands we replace. If your complex was built between 1950 and 1990, we can audit your panels to determine if you have one of these brands.
Will upgrading my panels lower my insurance premiums?
In many cases, yes. Insurance carriers increasingly flag these panel brands during underwriting inspections. A documented upgrade can help you retain coverage or qualify for better rates — we provide documentation you can share with your insurer.
Do you coordinate with SMUD or PG&E for the utility disconnect?
Yes. We handle all communication and scheduling with the utility company for the disconnect/reconnect window, so you don’t have to manage that coordination yourself.
Do you work with property management companies overseeing multiple properties?
Yes. We regularly work with property managers and HOAs to schedule and complete panel upgrades across multiple buildings or complexes.
