Full Project vs. On-Site Work
A straightforward Level 2 job is usually a 2-6 week project, but the physical installation commonly takes 1-2 days per port. The remaining time covers assessment, plans, permits, procurement, inspection, and activation.

How Much Time Should You Allow for Commercial EV Charger Installation Projects?
EV Chargers Phoenix estimates that a straightforward Level 2 commercial EV charger project in Phoenix typically takes two to six weeks from site assessment through activation, even though on-site electrical work often takes only one to two days per port. Permitting, equipment lead time, panel capacity, trenching, and utility coordination shape the schedule. Panel or new-service work can add time, while DC fast charging projects may take two to six months.
Quick Summary
- A standard Level 2 commercial installation typically takes 2-6 weeks total, including permitting and inspection.
- On-site electrical work usually takes 1-2 days per charger, or about 8-16 hours of hands-on labor per standard port.
- Permit review typically adds 1-3 weeks, while equipment procurement can take 1-4 weeks.
- Panel upgrades or new service runs can add 1-4 weeks; DC fast charger projects often take 2-6 months, and June-September monsoon weather can delay trenching or asphalt work.
Commercial Installation Highlights
Capacity, Access, and Permits
Panel headroom for a new 240V or three-phase circuit, the number of ports, conduit distance, trenching through asphalt or concrete, permit jurisdiction, and equipment availability can all move the completion date.
Plan Larger Rollouts in Phases
Installations with four or more ports typically take 4-8 weeks total once permitting, procurement, and phased electrical work are included. A service upgrade can extend the schedule, while phasing can bring the first ports online before the remaining work is complete.
What to Inspect Before Scheduling Work
Panel-to-Parking Conduit Route
The electrical panel, parking spaces, and proposed conduit path, including any asphalt or concrete that requires trenching. This distance and surface work can add days to installation.
Level 2 and DC Fast Charging Infrastructure
Compare a Level 2 site using available panel capacity with a DC fast charging site that needs higher-voltage equipment, a dedicated transformer, and civil work. The infrastructure difference explains the much longer DC timeline.
Final Testing and Commissioning Checks
Load testing, ground-fault verification, and network connectivity checks before final inspection. Commissioning confirms that the mounted equipment is ready to energize.
Phase-by-Phase Snapshot
Planning and Site Assessment
Allow 3-10 days to review parking layout, panel location, existing service size, ADA-accessible placement, parking counts, and load calculations. Larger multi-port or DC projects may also need a utility feasibility review.
Permits and Code Review
Most Phoenix-area permit reviews take 1-3 weeks. Commercial plans must address the applicable electrical permit and inspection requirements, NEC Article 625, grounding under NEC 250, UL 2594, and UL 2202 where applicable.
Procurement and Electrical Upgrades
Equipment procurement typically takes 1-4 weeks. If the panel is at or near capacity, an upgrade generally adds 1-2 weeks before dedicated circuits, overcurrent protection, grounding, and surge protection can be completed.
Testing and Commissioning
Allow 1-2 days for load testing, ground-fault verification, connectivity checks, defect troubleshooting, and preparation for final inspection. Activation follows once the installation passes inspection.
Commercial Installation Timeline
| Phase | Typical Duration | What Happens |
|---|---|---|
| Site assessment and design | 3-10 days | Review parking layout, panel location, service size, charger placement, and load calculations. |
| Permitting and code review | 1-3 weeks | Submit electrical plans for the applicable Phoenix-area jurisdiction and resolve review comments. |
| Equipment procurement | 1-4 weeks | Secure chargers, switchgear, and other required electrical equipment. |
| Electrical or panel upgrades | 1-2 weeks | Add capacity before circuit and conduit work; a new service run can add 1-4 weeks. |
| Installation and mounting | 1-2 days per port | Install conduit, cable, grounding, protection, mounting hardware, and charging equipment. |
| Testing and commissioning | 1-2 days | Verify load, ground-fault protection, connectivity, and final inspection readiness. |
What the Timeline Means
The full timeline starts with the site walk and ends when the charger passes final inspection and energizes; it is not a count of continuous labor hours. At the simplest end, a single small-business Level 2 charger with adequate panel capacity may require only 2-4 hours of on-site electrical work, while commercial multi-port work generally takes one to two full working days per port.
What Changes the Installation Schedule
Existing capacity determines whether the site needs a dedicated 240V circuit, three-phase service, a panel upgrade, or a transformer. Port count, the distance to parking, trenching through asphalt or concrete, and charger or switchgear lead times also affect the sequence. Phoenix, Scottsdale, and Tempe have different review timelines, while monsoon weather between June and September can interrupt outdoor civil work. For DC fast charging, higher-voltage equipment, dedicated transformers, and civil work can extend the on-site build to 1-3 weeks and the complete project to 2-6 months.
Common Follow-Up Questions
Cost is a common follow-up: Phoenix-area Level 2 installations typically run $6,000 to $15,000 per port including labor, permits, and equipment, while the broader national range is $2,500 to $15,000 per unit depending on trenching and panel work. Shared trenching and panel work can place additional ports between $3,500 and $10,000 each, while DC fast charging starts around $50,000 per port once transformer and utility upgrades are included. A commercial panel upgrade generally ranges from $3,000 to $12,000 depending on the amperage increase and service-entrance work. Most commercial chargers last around a decade with proper care; outdoor equipment in Phoenix benefits from a NEMA 4-rated enclosure, regular cleaning, connector inspection, and firmware updates. Eligible commercial properties may also qualify for the Section 30C Alternative Fuel Vehicle Refueling Property Credit, subject to current federal eligibility rules.
