How Long Does EV Charger Installation Actually Take?
Most homeowners expect EV charger installation to be a same-day job. In reality, on-site work is usually 2 to 4 hours, but the full process including permit and inspection takes 5 to 10 business days in Henderson. Here is exactly what happens during each stage and what can slow it down.
The Quick Answer
| Stage | Typical Time |
|-------|-------------|
| Initial site assessment | 30 to 60 minutes |
| Permit application processing | 1 to 3 business days |
| Actual installation on-site | 2 to 4 hours |
| City of Henderson inspection | 1 to 3 business days to schedule |
| Total from first call to energized charger | 5 to 10 business days |
Rush jobs: If you need a charger installed urgently (say you just picked up a new EV and have no charging at home), we can sometimes compress the timeline to 3 to 5 business days by paying expedited permit fees.
Stage 1: Site Assessment (30 to 60 Minutes)
Every good install starts with an electrician visiting your home. Skipping this step is how people end up with surprise charges or botched installs.
What happens during the assessment:
- Electrician inspects your electrical panel, noting brand, amperage, available breaker space
- Checks existing load (dryer, AC, range, pool pump) to calculate available headroom
- Walks the conduit route from panel to where you want the charger mounted
- Measures the actual run distance (matters for wire gauge)
- Looks at mounting surface and considers any HOA aesthetic requirements
- Discusses which charger you want (Tesla Wall Connector, NEMA 14-50, ChargePoint, etc.)
Henderson note: Site assessments are free from us. Some contractors charge $75 to $150 for this. Always ask before scheduling.
What can slow this down:
- Locked gates or pets (let the tech in promptly)
- Panels behind furniture or storage (clear the area before the visit)
- Detached garages or complex routes (longer walk-throughs)
Stage 2: Quote and Acceptance (Same Day to 2 Business Days)
After the site visit, the electrician puts together a fixed-price quote. Good quotes include:
- Charger make, model, amperage
- Breaker size
- Wire gauge and length
- Conduit run details
- Permit fee (itemized)
- Labor total
- Any panel work required
- Warranty terms
Henderson average response time: Our team returns quotes within 24 hours. Some contractors take 3 to 5 business days, which slows the whole timeline. Ask upfront about turnaround.
Stage 3: Permit Application (1 to 3 Business Days)
Every EV charger installation in Henderson requires a City of Henderson electrical permit. The permit verifies the installation meets code before and after the work happens.
What happens during permit application:
- Electrician submits the application online or in person
- Includes a one-line diagram showing panel, breaker, wire, and charger specs
- Pays the permit fee ($75 to $150)
- Henderson processes the permit (1 to 3 business days typical)
Typical permit issue timing:
- Simple NEMA 14-50 or Wall Connector install: 1 to 2 business days
- Installs requiring a panel upgrade: 3 to 5 business days (city reviews load calcs)
- Rush permits: same-day to next-day, costs extra $50 to $125
Why it takes this long: The City of Henderson Building and Fire Safety department reviews residential permits in order received. Digital submissions process faster than walk-ins. In summer, when everyone is upgrading AC and pools, backlogs can stretch to 5 business days.
Stage 4: Scheduling and Parts (1 to 5 Business Days)
Once the permit is approved, we schedule the install. This depends on:
- Electrician availability (we book 3 to 10 business days out in peak season)
- Charger availability (Tesla Wall Connector sometimes has 1 to 2 week shipping; we keep common units in stock)
- Your availability (someone needs to be home for the install)

Stage 5: The Actual Installation (2 to 4 Hours)
This is the only step most homeowners see. It is also the fastest part of the whole process.
Typical Installation Breakdown
Basic NEMA 14-50 or Wall Connector in attached garage:
- Setup and safety check: 15 minutes
- Panel work (breaker install, connections): 30 to 45 minutes
- Conduit run and wire pulling: 45 to 90 minutes
- Mount charger and make final connections: 30 to 45 minutes
- Testing and commissioning: 15 to 30 minutes
- Total: 2 to 3.5 hours
Installations that take longer:
- Long conduit runs (50+ feet): add 30 to 90 minutes
- Finishing drywall or stucco patches: add 30 to 60 minutes
- Detached garage, outbuilding, or underground trenching: add 2 to 6 hours
- Panel upgrade (200A or subpanel): add 3 to 8 hours
- Rocky or compacted soil for trenching: adds 1 to 3 hours
Anthem specific: Gated community coordination with security adds 15 to 30 minutes up front. Not a big deal once we have done a few installs in a neighborhood.
MacDonald Ranch specific: Larger lots and often detached structures mean 4 to 6 hour installs are normal. We plan accordingly.
What to Expect During the Install
- We turn off power to the panel for 10 to 30 minutes during breaker install
- You might want to unplug electronics before we start (computers, TVs, servers)
- We place drop cloths and protective mats in the work area
- The electrician will ask where you want the charger mounted (exact height, position)
- Expect some dust from anchor-drilling (we clean up after)
Stage 6: Inspection (1 to 3 Business Days)
After the install, the City of Henderson sends an inspector to verify the work meets code. You do not need to be home for most inspections.
Typical inspection timeline:
- We schedule the inspection the same day as the install
- City of Henderson typically inspects within 1 to 3 business days
- Summer months can stretch to 3 to 5 business days (AC and pool rush)
What the inspector checks:
- Breaker size matches circuit and charger
- Wire gauge correct for amperage
- GFCI protection where required (NEC 2020/2023)
- Grounding and bonding proper
- Panel workmanship (no loose connections, proper torque)
- Conduit routing code-compliant
- Charger rated for location (indoor vs outdoor)
If the inspection fails: About 1 in 30 installs we do fail first inspection, usually for a minor issue like a label missing on the panel. We fix it within 24 hours and reschedule. Another 1 to 3 business days.
Once the inspection passes, your charger is permitted to use at full capacity.
How to Speed Up the Timeline
Book in the off-season. November through March is slower for Henderson electricians. Same-week availability is common.
Choose a popular charger. Tesla Wall Connector, NEMA 14-50, ChargePoint Home Flex are all in stock with most Henderson electricians. Rare brands mean shipping delays.
Choose a simple install location. A charger next to the panel is 2 hours. A charger 80 feet away through a finished ceiling is 6 hours.
Pay for expedited permits. Rush permit service in Henderson costs $50 to $125 extra and cuts 2 to 3 business days off the front end.
Have HOA paperwork ready. If your HOA requires architectural approval, submit the paperwork the day you accept the quote. Do not wait.
Clear the install area. Moving stuff out of the way before the electrician arrives saves 30 to 60 minutes.
What Slows It Down (Things Beyond Your Control)
- Panel upgrade required: Adds 1 to 3 weeks due to NV Energy coordination
- Summer permit backlog: July and August permits take 3 to 5 business days
- Material shortages: Aluminum wire, specific breaker brands, proprietary chargers
- HOA architectural review: Some HOAs take 2 to 4 weeks to respond
- Weather delays: Monsoon storms (July through September) push outdoor work
The Charge Station Pro and Harder Installs
Ford F-150 Lightning owners installing the Charge Station Pro at 80 amps should plan for 6 to 10 business days total. 80A installs trigger closer load calculation review at the permit stage.
Tesla Powerwall combined with EV charger install: 10 to 20 business days because of the battery and transfer switch coordination.
Frequently Asked Questions
Can you install an EV charger in one day?
The actual installation work is almost always one day (2 to 4 hours on site). What takes longer is the permit processing and inspection, which are controlled by the City of Henderson, not us. The full process is typically 5 to 10 business days from first call.
Can I install an EV charger without a permit to save time?
No, and do not try. Insurance companies deny claims for fires caused by unpermitted electrical work. Home buyers and inspectors flag unpermitted work at resale. The permit fee ($75 to $150) is trivial compared to the liability.
What is the fastest you can install a charger in Henderson?
Rush service with expedited permits can get a simple NEMA 14-50 done in 3 to 5 business days. Nothing faster than that is feasible without skipping inspection, which we will not do.
Do I need to be home during the whole install?
No. You need to let the electrician in, be available for a final walkthrough, and sign off on the work. That usually means being home at the start and end, but you can run errands in between. You do not need to be home for the inspection.
How long does a panel upgrade add to the timeline?
2 to 3 weeks typically. NV Energy has to coordinate a meter disconnect and reconnect, which takes 5 to 10 business days on its own. The actual upgrade work is 6 to 10 hours. Add permit and inspection time.
Will the install shut off my power?
Only for the 10 to 30 minutes when we are working inside the panel. Most of the install (pulling wire, mounting charger) happens with power on. We give you 5 minutes warning before cutting power so you can save work or unplug electronics.
