BOTTOM LINE UP FRONT (BLUF)
Westover is one of those Arlington neighborhoods where homes sit on slightly larger lots than the surrounding area, with mature trees, detached garages set back from the main house, and a mix of construction from the 1930s through the 1960s. The Westover Village center provides a walkable hub. The residents are heavily federal, professional, and academic. EVs show up in driveways but the original homes were not built with EV charging in mind. The install conversation in Westover combines older home wiring concerns with detached garage layouts and the occasional pedestal install for homes without garages.
This article walks you through what a proper Level 2 EV charger install looks like in Westover. If you want the full technical guide, the Northern Virginia cornerstone article goes deeper. If you want to talk about your specific home, the service page has my direct line.

Westover Home Realities for EV Charging
A typical Westover home was built between 1935 and 1965 on a quarter-acre to half-acre lot. The lots are slightly larger than the surrounding Arlington neighborhoods which leaves room for detached garages, sheds, and the occasional carriage-house style structure. The electrical service in Westover varies. Some homes have been recently renovated and updated to 200 amp service. Others still run on 100 amp or 150 amp service from a panel upgrade done in the 1980s or 1990s. The first step of the EV charger install conversation is always the load calculation.
Detached Garage Conduit Runs
Many Westover homes have detached garages twenty to fifty feet back from the main house. The conduit run from the main service to the garage is buried at code depth in PVC conduit. For runs over fifty feet, we typically install a sub-panel at the garage to reduce conductor sizing and add flexibility. For shorter runs, we run direct conduit. Either approach is clean and code compliant. We coordinate the trenching with any existing landscape during the site visit.
Service Upgrade for Older Westover Homes
If your Westover home still has the 100 amp or older 150 amp service from a previous decade, the load calculation usually shows it cannot safely accept a new 50 amp continuous EV charger circuit. A 200 amp panel upgrade or full service upgrade is the path forward. The upgrade also future-proofs the home for additional electric loads. For Westover homes that already have 200 amp service from a recent renovation, the EV charger install is straightforward.
Cost and Arlington County Permitting
Westover installs without a service upgrade typically run $1,800 to $3,000 for the install labor plus $500 to $900 for the charger. Detached garage conduit runs add $800 to $2,000 depending on distance. Sub-panel installs at the garage add $800 to $1,500. Service upgrades add $3,000 to $8,500 if needed. Arlington County permits and inspections are handled as part of the install. Total timeline from contract to power on is three to six weeks for a straightforward install or six to ten weeks if a service upgrade is included.
Frequently Asked Questions
Can I install in my detached Westover garage?
Yes. We run buried conduit from the main service to the garage. For longer runs, we install a sub-panel at the garage to reduce conductor cost.
Will my Westover home need a service upgrade?
It depends on the existing service size. Older Westover homes with 100 amp or 150 amp service often need an upgrade. Homes already at 200 amp service usually do not.
What if I do not have a garage in Westover?
We install a pedestal-mounted charger at the edge of the driveway with the conduit buried from the house service. The result is weatherproof and code compliant.
Does Arlington County require permits?
Yes. Every new dedicated 240 volt circuit requires a permit and inspection. We handle both as part of the install.
How long does install take in Westover?
Three to six weeks for a straightforward install with a detached garage run. Six to ten weeks if a service upgrade is included.
