Why 200 amp service upgrade comes up in Baltimore
Baltimore rowhouse renovations often include central air, a modern kitchen, a basement apartment or an EV charger, and many rowhouses still have 60 or 100 amp services. A 200 amp upgrade usually includes a new meter base, and BGE has rules about meter placement on rowhouse fronts and rear walls. Historic districts such as Fells Point and Mount Vernon review visible exterior changes.
Permits come from the Department of Housing and Community Development, and BGE schedules the disconnect and reconnect. Rowhouse basements are often tight, so the new panel location should leave proper working clearance.
- Many Baltimore rowhomes have 60 or 100 amp services that cannot support central air, a modern kitchen and a basement apartment together.
- Older homes may have 60 or 100 amp services, so a load calculation decides whether a 40 or 48 amp charger fits.
- Permits in Baltimore
- Baltimore City and Baltimore County are separate jurisdictions. In the city, electrical permits are issued by the Department of Housing and Community Development; the county has its own permits office. Maryland electricians are licensed by the state or locally.

200 Amp Service Upgrade in Baltimore: questions
Do I need a permit for 200 amp service upgrade in Baltimore?
Usually, yes. Baltimore City and Baltimore County are separate jurisdictions. In the city, electrical permits are issued by the Department of Housing and Community Development; the county has its own permits office. Maryland electricians are licensed by the state or locally. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Baltimore?
If the work affects the meter or service, the electrician coordinates with BGE, 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.
