As of 2022, Washington, D.C. ranked third in the nation for EV ownership per capita, with more than 2,300 registered plug-in vehicles. The metro area also placed among the top five nationwide for EV readiness, thanks to growing infrastructure and local incentives. This upward trend means more homeowners in historic neighborhoods are exploring what it takes to charge at home. Many D.C. homes built in the early to mid-20th century still run on 60- to 100-amp service. That was plenty of power for a simpler time, but today's homes demand more, especially if you're adding an EV charger into the mix.
Level 2 EV chargers, the most practical option for overnight charging, typically require a dedicated 240-volt circuit and draw significantly more power than a standard outlet. In most historic homes, installing one without first upgrading your electrical panel is neither feasible nor safe.
To prepare for EV charger installation, many homeowners need what's known as a "heavy-up," a service panel upgrade that increases your home's electrical capacity. Moving from 100 amps to 200 amps gives your system the headroom it needs to safely power your vehicle along with the rest of your household.
In D.C., heavy-ups must comply with city-specific electrical codes, and homes in historic districts often face additional permitting steps, which makes experience and local knowledge essential. Working with an electrician who understands both the process and how to avoid disrupting the character of an older property is the key to a smooth installation.
If you're considering EV ownership, the best first step is a professional electrical assessment. A licensed electrician will evaluate your current panel, wiring, and household usage to determine what kind of upgrades, if any, are needed.

Once a heavy-up is complete, we'll help you choose the right EV charger, determine the best location for installation, and ensure all work is code-compliant and efficient.
EV ownership is exciting, but planning for your charging needs at home is just as important as choosing the right vehicle. In older D.C. homes, a smart installation starts with understanding your home's limits and how to upgrade responsibly.
