Below is what we find when we walk into a Georgetown home for an EV charger consultation, what makes the work different here than in Bethesda or Capitol Hill, what drives the cost, and how install day actually goes.

What this guide covers

This page walks through the realities of installing a Level 2 EV charger in Georgetown — the housing-stock and panel-capacity constraints, where chargers can physically mount on a federally-reviewed historic exterior, the Old Georgetown Act review process for visible work (which is NOT HPRB — Georgetown is its own thing), Pepco coordination patterns, and what to expect on install day. If you're past the research phase and want a quote, call (703) 997-0026 or email info@ajlongelectric.com.

When Georgetown homeowners call us about EV charger installation

Most EV charger calls fall into one of these patterns:

  • The car just arrived and the Level 1 cord can't keep up. The mobile cord that ships with most EVs is Level 1 (120V) — overnight charging adds 30–40 miles. A Level 2 (240V) install adds 25–35 miles per hour, 5–10× faster, and converts an overnight session into a full charge.
  • The garage is in the rear alley and we need to route a 240V circuit there. Common pattern in N Street, P Street, Volta Place, Q Street rowhouses. The conduit run from a basement panel to a rear-alley garage is often 50–80 feet — through brick, around stairs, across a basement ceiling.
  • There's no garage, the car parks on the street, and the question is whether a façade-mounted charger is even possible. Any exterior-visible electrical work in Georgetown triggers Old Georgetown Board review. We'll tell you on the walk-through which scenarios are likely approved and which aren't.
  • The panel can't handle a 40-amp circuit. A 100-amp panel in a 1900-built rowhouse that's already powering modern HVAC, a kitchen renovation, and a tankless water heater rarely has 40 amps of headroom for a Level 2 charger. Service upgrade comes first; charger second.
  • Condo board or HOA pre-approval. A few converted-rowhouse condo buildings in Georgetown require board sign-off before tapping common electrical for a new dedicated circuit.

What makes EV charger installation in Georgetown different

Three things separate Georgetown EV charger work from almost anywhere else in the DMV:

Where the charger physically mounts

Mounting location matters more in Georgetown than in suburban installs because the exterior is federally protected. Three scenarios cover most jobs:

Alley-garage mount. The cleanest install: charger on the interior or exterior wall of a rear-alley garage, 240V circuit running from the basement panel through the rear of the rowhouse. Exterior visibility is limited to the alley. OGB still reviews any work visible from a public right-of-way, but alley-side installs are generally the easiest path to approval.

For homes without alley garages, a charger mounted on the front or side of the building means the unit, the conduit, and any weatherhead are all visible from the public right-of-way and trigger Old Georgetown Board review. Approval is possible but constrained: paintable conduit matching the brick, mounting heights OGB will accept, exterior box finishes specified by the review. Add 4–8 weeks of review on top of the standard permit timeline. Curbside-charging in the public right-of-way is a separate DDOT permitting question and not a private-property install we currently do.

DC permits: DOB, plus OGB/CFA review for Georgetown specifically

DC's residential electrical permitting is now handled by the Department of Buildings (DOB) — renamed from DCRA in October 2022. DOB issues the standard electrical permit for any new dedicated circuit, including the 240V circuit a Level 2 charger requires. Permit issuance is typically same-day to two business days for an interior-only scope.

For any exterior-visible work, Georgetown's federal historic designation under the Old Georgetown Act of 1950 kicks in. The Old Georgetown Board (OGB) reviews the application and makes recommendations to the U.S. Commission of Fine Arts (CFA), which gives final approval. This is the part most contractors get wrong: they assume HPRB (which handles every other DC historic district) applies. It doesn't. Georgetown sits on its own federal review track, the timelines are longer, and the design standards are stricter.

Practically: a charger mounted inside an alley garage or in a basement, with conduit not visible from any public right-of-way, doesn't require OGB review. A façade-mounted charger, an exterior conduit run, or any visible weatherhead does. We pull the DOB permit on every job and submit the OGB application when the scope requires it. After 30 years of work across Northern Virginia, DC, and Maryland, we've done enough Georgetown installs to know what gets approved on the first review and what needs revision.

The 240V circuit run through a brick rowhouse

  • Brick exterior walls have no cavity space. Running conduit along the interior of an exterior brick wall usually means surface-mounted EMT, rigid conduit along a baseboard or chase, or routing through an interior wall instead. We walk the route with the homeowner before drilling.
  • 240V runs are long. A typical run from the basement panel to a rear-alley garage is 50–80 feet. Wire gauge matters at that distance — we default to #6 copper THHN, sized for voltage drop, not the bare minimum a shorter run would allow.
  • Pepco service drops vary by block. Some blocks have rear-alley service; some are fed from a front-facing transformer. When the install requires a service upgrade first, Pepco's disconnect window has a 2–4 week lead time — we handle the scheduling.

What drives the cost of an EV charger install in Georgetown

We don't post a fixed install price on this page because every Georgetown job is different — different panel, different mount location, different review path. Call for an on-site quote. Here's what shifts the number up or down:

  • Distance from panel to charger location. A 20-foot run from the panel to an adjacent basement wall is a different job than an 80-foot run through brick, around stairs, and out to a rear-alley garage. Material costs and labor hours scale with the run length.
  • Existing panel capacity. An NEC Article 220 load calculation determines whether your existing service can absorb a 40-amp continuous load. If the math puts you over, a panel upgrade or full service upgrade comes first and the EV-charger install rolls into the larger scope.
  • OGB / CFA review for exterior-visible work. Interior-only installs don't trigger historic review. Façade-mounted chargers, exterior conduit, or new weatherheads do — adding 4–8 weeks of review timeline plus the application/review fees that vary by scope.
  • Charger model and amperage. A 40-amp Tesla Wall Connector, a 48-amp ChargePoint Home Flex, a 50-amp Grizzl-E, a Wallbox Pulsar Plus, an Emporia Vue, or an Eaton charger all have different mounting hardware, breaker requirements, and wire-gauge implications. We install all major brands.
  • Hardwired vs. plug-in (NEMA 14-50). Hardwired installs allow the highest amperage and remove the failure point of a high-current outlet, but cost slightly more. Plug-in installs to a NEMA 14-50 receptacle are faster and let you take the charger when you move. Both are code-compliant when done right.
  • Pepco coordination for service-upgrade-first scope. If your panel needs to come out before the charger goes in, Pepco's coordinated disconnect adds roughly half a day plus a 2–4 week scheduling lead time.

What happens on install day

A typical interior-only Georgetown EV charger install is a one-day, 4–8 hour job. Installs involving a service upgrade or OGB-reviewed exterior work span 1.5–2 days on-site, after permitting wraps up.

  1. Site walk and load calc confirmation. We confirm the route, the mount location, and the panel capacity numbers we ran during the quote. Drop cloths down, materials staged.
  2. Circuit installation. Pull the new 240V circuit from the panel to the charger location — #6 copper THHN by default on a 50-amp breaker, sized for voltage drop and ampacity. Conduit routed along the agreed path. New double-pole breaker landed in the panel.
  3. Charger mount and termination. Charger mounted to the agreed surface; conductors terminated to manufacturer torque specs; cover plates back on.
  4. Energize, test, document. Energize the new circuit, run a charging-session test with the homeowner's vehicle (or an EVSE tester if the car isn't on-site), verify amperage and voltage under load. DOB inspection follows within a few days.
  5. Cleanup and walk-through. Conduit ends sealed, work area broom-clean, charger app paired to the homeowner's phone, panel directory updated.

Frequently Asked Questions

Do I need Old Georgetown Board approval for an EV charger?

Only if some part of the install is visible from a public right-of-way. A charger mounted inside an alley garage with conduit hidden in interior chases or basement ceiling space typically doesn't trigger OGB review. A façade-mounted charger, exterior surface conduit on the front or street-facing side of the building, or a new exterior weatherhead does — and that adds 4–8 weeks of review on top of the standard DOB permit timeline. We assess this on the on-site walk and tell you upfront which scenario applies.

Can my existing 100-amp panel handle a Level 2 EV charger?

Maybe — depends on what else is on the panel. We run an NEC Article 220 load calculation summing your existing continuous loads (HVAC, water heater, range, dryer, kitchen circuits) against the panel's rated capacity. A 40-amp continuous load needs real headroom; in many 1900-built rowhouses with original 100A service already at 85% capacity, the math doesn't work. The fix is a panel upgrade to 200A first, then the charger. Load calc is included in every quote.

How long does the install take from start to finish?

Interior-only scope: 2–4 weeks from quote to completed install (mostly DOB permitting and Pepco scheduling), with a 4–8 hour install day. Scope involving OGB/CFA review: 8–14 weeks. Scope involving a panel or service upgrade first: add 2–4 weeks. Install day is short; the calendar time is the permitting and review cycle.

Which EV charger brands do you install?

All major Level 2 brands: Tesla Wall Connector, ChargePoint Home Flex, Wallbox Pulsar Plus, Grizzl-E, Emporia Vue, Eaton. We don't sell chargers — you buy the unit and we install it. We can recommend based on your panel capacity, install location, and hardwired vs plug-in preference.

Hardwired or plug-in (NEMA 14-50)?

Hardwired is the cleaner long-term install: no high-current receptacle as a failure point, full charger amperage available, and the unit becomes part of the building. Plug-in to a NEMA 14-50 outlet installs faster, is portable if you move, and is code-compliant when the receptacle and circuit are sized correctly. Most Georgetown installs we do are hardwired — but we're happy with either approach.

Will Pepco need to disconnect my power, and how long is the outage?

For most interior-only EV charger installs, no — we land the new breaker in your existing panel and the rest of the house stays energized. We briefly de-energize the panel during the connection, but it's 30 minutes to an hour, not a full-day outage. If the scope includes a service upgrade first, Pepco coordinates a temporary disconnect for that step — expect a 4–6 hour outage. We arrange Pepco scheduling on your behalf.
