As EV adoption accelerates in New Jersey, condo and HOA boards across Hudson County and beyond are facing a growing challenge: individual residents want EV chargers, but the building lacks the infrastructure to support them. The answer — increasingly — is building-wide shared EV charging infrastructure: a planned, professionally designed system that serves multiple residents from shared electrical capacity, with individual billing for each user.
Here is how shared EV charging works in NJ condo buildings, what it costs, how the permits work, and how we approach the design process for buildings of all sizes.
Why Shared Charging Instead of Individual Installs?
When every resident with an EV installs their own dedicated 240V circuit from the building's electrical room to their parking space, you end up with multiple high-amperage circuits all competing for the same limited shared electrical service. Buildings with 100–200 amp shared service in their garage often run out of electrical capacity after just 3–5 individual charger installations. The seventh resident who wants a charger gets told there is no room — and the building faces a full service upgrade anyway.
A planned shared charging system solves this by designing the infrastructure for the building's total needs upfront, using load-managed charging stations that share available electrical capacity intelligently across all chargers. Instead of each charger getting a dedicated maximum-amperage circuit, a load management controller monitors the building's total draw and distributes available amps across all connected vehicles — giving each car what it needs without exceeding the building's service capacity.
How Individual Billing Works in a Shared System
This is the most common question from HOA boards: if the electricity comes through a shared building account, how do we bill each resident for what they actually use?
Modern commercial-grade Level 2 chargers designed for multi-family buildings — products like the ChargePoint CPF50, Enel X JuiceBox for Business, or Blink IQ 200 — include built-in RFID or app-based authentication and metering. Each resident gets an RFID card or app account. The charger logs every session with the resident's ID, kilowatt-hours consumed, and session duration. The building management company (or a third-party billing platform) generates monthly statements for each resident based on their actual usage at a pre-agreed per-kWh rate.
The billing platform also handles the building's wholesale electricity cost recovery — the building pays PSE&G for the electricity, residents pay the building (or directly to the billing platform) for what they charge. Some platforms handle collections automatically via ACH or credit card.
The Permit Process for Multi-Family EV Charging in NJ
Shared EV charging systems in NJ condo or HOA buildings require:
- Commercial electrical permit (not residential) — multi-family charging infrastructure is classified as commercial electrical work in most NJ municipalities
- NJ electrical inspection with a licensed commercial electrical inspector
- PSE&G or JCPL utility coordination — the utility must approve any significant load additions to the building's service, and may require a new service agreement or meter configuration
- AHJ (Authority Having Jurisdiction) review — in some municipalities, the local fire marshal reviews the installation plan for battery or charging infrastructure in enclosed parking garages
The permit process for a building-wide system is more complex than a single residential installation, typically taking 6–12 weeks from permit application to final inspection. Experienced contractors who specialize in multi-family EV charging — which we do — manage this process with the building's management company from start to finish.
What Does Building-Wide EV Charging Infrastructure Cost?
Costs vary significantly based on the building's existing electrical capacity, parking structure type, and number of charging spaces. For planning purposes:
- 4–6 space system (small building or initial phase): $8,000–$18,000
- 10–20 space system (mid-size condo building): $20,000–$50,000
- 50+ space system (large building or campus): $60,000–$150,000+
These ranges include the charging station hardware, load management controller, conduit runs through the parking structure, panel and service upgrades if required, permit fees, and installation labor.
The good news: commercial EV charging installations qualify for the Alternative Fuel Vehicle Refueling Property Credit (Section 30C) — a 30% federal tax credit on charging infrastructure costs for multi-unit properties. This applies to the condo association as a property owner, and can meaningfully offset the capital cost of the infrastructure. Additionally, the NJ BPU has administered commercial EV charging incentive programs that have historically provided additional rebates for multi-family installations.
A Phased Approach for Buildings Starting Small
Many buildings we work with are not ready to install 20 charging stations on day one. We recommend a phased approach: design the full system upfront (conduit runs, service capacity, billing infrastructure) but only install charging stations for current residents with EVs. Pre-running conduit to all parking spaces during Phase 1 is far cheaper than retrofitting it later — the conduit cost is relatively small, but the disruption and re-permitting of adding conduit later is significant.
This gives current EV owners the chargers they need now, positions the building for the next 10–15 years of EV adoption growth, and avoids the "we can only do 3 more chargers" conversation in three years.
