1. Why add EV charging to your property
Electric vehicles are becoming a normal part of everyday parking. For residential communities, on-site charging is an amenity residents look for when choosing where to live. For workplaces and businesses, chargers can attract visitors, support employees and prepare fleets for electrification.
Planning early also matters for the electrical side: the cheapest time to add capacity, conduit and pads is before parking lots are repaved or new buildings are finished.
2. Charger types compared
Commercial chargers fall into two main groups. The right choice depends on how long vehicles stay parked and how much power your site can deliver.
| Feature | Level 2 (AC) | DC Fast Charging |
|---|---|---|
| Typical supply | 208V or 240V single-phase | 480V three-phase |
| Typical power | About 7 to 19 kW per port | About 50 to 350 kW per unit |
| Best for | Apartments, workplaces, hotels, long-stay parking | Retail, travel corridors, fleets needing quick turnaround |
| Electrical impact | Moderate, often fits existing or upgraded service | High, often needs a new service or transformer work with the utility |
| Installed cost | Lower | Much higher |
Rule of thumb: if drivers park for several hours (overnight at home, a work shift), Level 2 is usually the most cost-effective option. DC fast charging makes sense where turnaround time is the priority.
3. How many chargers you need
Start with how many drivers will use the site, how long they stay, and how that will grow. Many properties install a first phase of chargers and, at the same time, run conduit and size equipment for future spaces. Building "EV-ready" spaces now avoids tearing up pavement again later.
- Count parking spaces and expected EV drivers today and in five years.
- Check local zoning or redevelopment requirements for EV-ready or EV-installed spaces.
- Decide which spaces are assigned, shared or accessible, and plan for ADA-compliant access.
4. Understanding electrical capacity
The electrical service is the backbone of every EV project. Before anything is installed, a load calculation determines how much capacity is available and whether the site needs an upgrade.
What we evaluate
- Existing service size, meters and panels
- Current building load and peak demand
- Distance from the electrical room to the parking area
- Whether a new service, meter bank or panel is the better path
- Load management options that let more chargers share the same capacity
When a new service is needed, the project is coordinated with the local utility, which sets its own timelines for design and energizing new meters. Starting that conversation early keeps the schedule realistic.
5. Site work & layout
Most of an EV project happens before a charger is ever mounted. Typical site work includes:
- Trenching and underground conduit from the electrical source to each charger location.
- Concrete pads and bases for pedestal chargers and electrical equipment.
- Pedestals and protective bollards to keep chargers safe from vehicles and snow removal.
- Feeders and branch circuits from the meter and panel to every station.
Good layouts keep cable runs short, keep chargers reachable from more than one space where possible, and leave room to add stations later.
6. Permits & inspections
EV charging installations in New Jersey require electrical permits through the local construction office, and the work must pass inspection before it is put into service. A licensed electrical contractor prepares the permit documents, coordinates inspections, and works with the utility on any service changes.
Astro Group Electric handles permits and inspections as part of the job, so property owners and general contractors don't have to chase paperwork.
7. Costs & incentives
Project cost depends mainly on the charger type, the number of ports, how far power must travel, and whether the electrical service needs an upgrade. Trenching distance and concrete work often matter as much as the price of the chargers.
| Cost driver | Why it matters |
|---|---|
| Charger hardware | Level 2 units cost far less than DC fast chargers. |
| Electrical capacity | A new service or transformer work can be the largest single cost. |
| Distance & trenching | Longer runs mean more conduit, wire and restoration. |
| Civil work | Concrete pads, bollards and paving repair. |
| Software & network | Ongoing fees for networked chargers. |
State and utility programs in New Jersey may help offset part of the cost for qualifying projects. Program rules and funding change, so ask us to review what currently applies to your property when we prepare your quote.
8. Networked vs. non-networked chargers
Networked chargers connect to software that lets you control access, set pricing, see usage and manage load across many stations. Non-networked chargers are simpler and have no ongoing software fees, but offer less control. Most multifamily and commercial owners choose networked stations so they can bill drivers and manage demand.
9. Your planning checklist
- Define who will charge, how long they park, and expected growth
- Choose Level 2, DC fast charging, or a mix
- Get a site assessment and load calculation
- Plan the layout, trench routes and future-ready spaces
- Coordinate with the utility on any service upgrade
- Pull permits and schedule inspections
- Install, test and commission the stations
