How Long Does a Level 2 EV Charger Installation Take?
The Short Answer
A straightforward Level 2 charger installation — panel in the garage, short wire run, no upgrade needed — takes 2–4 hours of physical work on the day of install. Add 1–5 business days for permit issuance beforehand and another 1–5 days to schedule the inspector afterward. If a panel upgrade or subpanel is required, plan for a separate full-day job before the charger goes in. Total elapsed time from first call to approved installation: 1–3 weeks is typical.
The physical installation itself is fast. The timeline most homeowners experience is dominated by permit scheduling and, in some cases, a panel upgrade — not the hands-on work of running wire and mounting the charger.
The hands-on install is typically 2–4 hours. Add permit issuance time (1–5 business days) and inspection scheduling (1–5 business days after the job is done). A simple garage installation with the panel nearby can go from permit approval to final sign-off in a single week. Complex runs or panel upgrades add time.
Installation Time Breakdown by Scenario
| Scenario | Physical Install Time | Notes |
|---|---|---|
| Panel in garage, short run (<20 ft) | 2–3 hours | Most common; straightforward |
| Panel in basement/utility room, run to garage | 3–5 hours | Conduit through wall or attic |
| Long wire run (50–100+ ft) | 4–6 hours | May require voltage-drop calc, larger wire |
| Panel upgrade required | Additional full day | Scheduled separately before charger install |
| Subpanel installation added | Additional 4–6 hours | Can sometimes be done same day |
The Full Timeline (Start to Finish)
- Day 1: Electrician visits for a site assessment and quote (30–60 min)
- Days 2–7: Permit application submitted and approved by AHJ
- Install day: Circuit run, breaker installed, charger mounted, wired, and tested (2–6 hours)
- Days after install: Inspector visit scheduled and conducted
- Final: Approved permit paperwork handed to homeowner
What Slows an Installation Down
- Panel at capacity — requires load-shedding device or full panel upgrade
- Long wire runs through finished walls or multiple floors
- Older homes with aluminum wiring or outdated panels
- Local AHJ backlogs extending permit or inspection wait times
- HOA approval process running in parallel
What Speeds an Installation Up
- Electrical panel located in or adjacent to the garage
- Conduit already roughed in (new construction or prior prep)
- 200 A service panel with available capacity
- Jurisdiction with same-day or next-day permit issuance
- Experienced EVITP-certified installer who knows the inspection checklist cold
Plan for One Week, Be Pleasantly Surprised
Set your mental expectation at 1–2 weeks from first call to inspector sign-off. Many installs wrap in 5–7 days total. Expecting the average prevents frustration if your local permitting office is slow.

Frequently Asked Questions
Can an electrician install a Level 2 charger in one day?
The physical installation absolutely happens in one day — often in under half a day. The multi-day timeline comes from permit processing and inspection scheduling, which happen before and after the install day itself.
Does the install take longer if I don't have a 200-amp panel?
Yes. A 100 A panel may not have capacity for a 40–60 A EV circuit without a panel upgrade or a load-management device. The upgrade itself is a separate job (typically a full day) that must be completed and inspected before the charger install proceeds.
Do I need to be home during the installation?
You or a trusted adult should be present, particularly at the start (to walk the electrician through the panel location and desired charger placement) and at the end (to test the charger and sign off on the work). For the inspection, you or the electrician can be present — confirm with your local AHJ who is required.
