Why 200 amp service upgrade comes up in Washington
DC rowhouse renovations often add central air, a heat pump, a modern kitchen, a basement unit and sometimes an EV charger, and many rowhouses still have 60 or 100 amp services. A 200 amp upgrade usually includes a new meter base and service entrance, and Pepco has rules about meter placement on rowhouse fronts and rear walls. Basement units may need their own meter.

200 Amp Service Upgrade in Washington: questions
Do I need a permit for 200 amp service upgrade in Washington?
Usually, yes. Electrical permits in the District are issued by the DC Department of Buildings, and work must be done by a DC-licensed electrician. Historic-district properties may also need review by the Historic Preservation Office. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Washington?
If the work affects the meter or service, the electrician coordinates with Pepco, which owns the meter and service drop.
Do I need 200 amps for an EV charger?
Not always. A load calculation may show that a 100 or 150 amp service can support a charger, especially with a lower charging setting or a load-management device.
How long does a 200 amp upgrade take?
The installation is often one day, but utility scheduling and permits can add days or weeks.
Does the utility charge for a service upgrade?
Some utilities charge fees or require their own work on the service drop. Policies vary, so ask your utility.
Is 400 amps ever needed?
For very large homes or homes with electric heat, pools and multiple EV chargers, a larger service may be justified by the load calculation.
