5 Signs Your Apartment Building Needs an Electrical Panel Upgrade

Short answer: An apartment building likely needs an electrical panel upgrade when breakers trip repeatedly, the electrical system can't keep up with modern tenant demand, the panels are decades old or from a discontinued manufacturer, you're seeing signs of overheating, or you're planning renovations or added loads like EV charging. Any one of these is worth a professional evaluation — together, they usually mean it's time.

For owners and property managers of multifamily buildings in Fort Wayne, Indianapolis, and across Indiana, the electrical panel is easy to ignore until it becomes a problem. Here are the five signs that mean you shouldn't wait.

1. Breakers trip over and over

An occasional tripped breaker is normal. A breaker that trips repeatedly is telling you the circuit is overloaded or something is wrong. In older apartment buildings, this often comes down to electrical systems designed for the appliances of decades ago now running today's microwaves, air conditioners, gaming setups, and space heaters. When tenants are constantly resetting breakers, the system has outgrown its capacity.

2. The building's electrical capacity can't keep up

Apartments built years ago were often wired with lower service capacity than modern living requires. If tenants can't run a window AC and a microwave at the same time, or units feel "starved" for power, the service and distribution equipment may simply be undersized for current demand. Upgrading the panels — and sometimes the service — brings the building in line with how people actually live now.

3. The panels are old or from a discontinued manufacturer

Panel age matters. Equipment that's several decades old is often at or past its service life, and certain older panel and breaker brands have well-documented reliability and safety concerns that have led professionals to recommend replacement. If your building still has original panels from its construction era, an electrician should evaluate whether they're a candidate for upgrade.

4. Signs of heat, corrosion, or damage

Warm or hot panel covers, a burning or "fishy" smell near electrical equipment, discoloration, buzzing, rust, or corrosion are all red flags. These are signs of loose connections, moisture intrusion, or failing components — conditions that raise fire risk. In a multifamily building, that risk is multiplied across every unit and every tenant.

5. You're renovating or adding new loads

Any time you're remodeling units, adding in-unit laundry, upgrading HVAC, or introducing EV charging for residents, the existing panels may not have the capacity or the available breaker spaces to support it. A panel upgrade is often the foundation that makes the rest of a modernization project possible — and it's far cheaper to plan for up front than to retrofit later.

What does an apartment panel upgrade involve?

The scope depends on the building, but it generally includes evaluating the existing service and load, replacing outdated panels, ensuring capacity for current and planned demand, and bringing the work up to current code with a permit and inspection. For multi-building or multi-unit properties, a good contractor will phase the work to minimize disruption to occupied units.

Frequently asked questions

How do I know if it's the panel or just one bad circuit? That's exactly what a professional load evaluation determines. Sometimes it's a single overloaded circuit; sometimes the whole panel is undersized or aging. An electrician can tell you which.

Can panel upgrades be done without displacing tenants? In most cases, yes — with planning. Work can often be scheduled and phased so individual units have only brief, coordinated outages rather than long displacements.

Is a permit required? Yes. Panel and service upgrades require a permit and inspection in Indiana. A licensed contractor handles this for you.
