The cost of a commercial EV charger installation is set mostly by the site, not the charger: how far the chargers are from power, whether the existing panel and service have capacity to spare, what the conduit has to cross, and whether the utility has to get involved. Two properties buying the same Level 2 chargers can end up with very different installed prices for those reasons alone.
That is why we do not publish a number, and why any quote given without walking the site is a guess. What we can do is explain every factor that moves the price, so that an owner, property manager or condo board can read a proposal, compare two of them fairly and make the decisions that keep the job under control.
1. Charger level and count
The Department of Energy's Alternative Fuels Data Center describes Level 2 charging as 240 volts in homes and 208 volts in typical commercial settings, and DC fast charging as equipment fed from three-phase power. That split drives everything else:
- Level 2 is the normal choice for workplaces, multifamily buildings, hotels and retail, where cars park for hours. Each port needs its own circuit, but the circuits are modest.
- DC fast charging needs far larger feeders, usually its own service equipment and often a new or larger utility transformer. It suits fleets and quick-turn locations, and it is a service project more than a charger project.
The number of ports matters in two ways. More ports mean more circuits and more wire, but the cost per port usually falls, because trenching, a new panel and the permit are shared across all of them.
2. Distance and what lies in between
This is often the single biggest variable. Every foot between the electric room and the parking spaces is conduit, wire and labor, and the surface the run crosses changes the method:
Surface lots
Crossing asphalt or concrete means saw-cutting and trenching, or directional boring under drive aisles, and then restoring the surface. Landscaping, irrigation and existing underground utilities all have to be located first. Pedestals also need bases, and exposed chargers usually need bollards or wheel stops.
Parking garages
Garages avoid trenching but bring their own work. Conduit usually runs exposed on ceilings and walls, penetrations through fire-rated walls have to be sealed properly, and coring through a post-tensioned slab needs scanning first so a tendon is not cut. Deep garages also tend to be where the mobile signal is weakest, which matters for networked chargers.
Wall-mounted in front of the building
When the electric room backs onto the parking, the run can be very short. That is the cheapest layout, and it is worth checking before settling on the spaces that look most convenient.
3. Panel and service capacity
Before anything is priced, someone has to answer whether the building has capacity to spare. That means a load calculation from the actual service rating and demand, not a guess from the panel label. The possible answers are:
- Spare capacity and spare spaces: the simplest case. The chargers feed from an existing panel or a new subpanel.
- Capacity, but no room in the panel: a new panel or a tap on the service, still a moderate job.
- No capacity: a service upgrade, which brings switchgear, utility coordination and a much longer schedule. Our commercial service and switchgear page and the post on when a business outgrows its service cover what that involves.
4. Load management instead of a bigger service
Chargers rarely all draw full power at once, and load management systems take advantage of that by sharing a fixed amount of capacity across many ports, or by lowering charging when the building's own demand peaks. Designed properly, that can let a property add many more ports than its spare capacity would otherwise allow, and avoid a service upgrade altogether.
The trade-off is slower charging at busy times, which suits overnight residential and all-day workplace parking and suits a fast-turnover retail lot less well. It is a design decision to make before the quote, because it changes the size of every feeder.
5. Utility work
If the project needs a new service, a separate meter or a larger transformer, the utility's schedule and requirements become part of the job. Most of South Florida is served by FPL, but some cities run their own electric utility (Homestead is one example), and the process differs. Utility work is the part of an EV project that no contractor controls, so it should be identified early, not discovered after the chargers are ordered.
6. Networked or non-networked chargers
Non-networked chargers simply deliver power. Networked chargers connect to software that can bill drivers, restrict access, report usage and share load. The hardware and ongoing software subscriptions are the owner's choice, but the electrical side changes too: networked chargers need a reliable data connection, either cellular signal where they are mounted or a hard-wired connection through low-voltage data cabling. In a garage, that can add a run of its own.
7. Permits, plans and inspections
Commercial charger installations are permitted work. Larger projects usually need drawings and a load calculation for plan review, and the permit comes from whichever building department has jurisdiction, which in Miami-Dade and Broward is often the city rather than the county. Plan review time is part of the schedule, and a clear submittal the first time is the easiest way to protect it.
8. Condominium rules
In a condo, the association's rules shape the project as much as the wiring does. Under section 718.113(8), Florida Statutes, a declaration cannot prohibit a unit owner from installing a charger within their own limited common element or exclusively designated parking area, and the owner gets an implied easement across the common elements to run the power. The owner pays for installation, operation, maintenance, repair and eventual removal, and the electricity must be separately metered or metered by an embedded meter and paid by the owner. The association may require the owner to follow bona fide safety requirements and reasonable architectural standards, use a licensed and registered firm familiar with the installation, and provide, within 14 days of approval, a certificate of insurance that names the association on the owner's policy for claims related to the charger.
For a high-rise, metering is what drives the price of an individual install: if the circuit comes from the owner's own meter, it may have to run many floors and a long way through the building, while an embedded meter at the parking space can shorten the run considerably. That is why many associations look at a building-wide approach instead, with shared infrastructure, a metered or networked system and a policy for who pays. Our page for property managers and condo associations and our commercial and multifamily EV charging page go into the options.
9. Climate and location
Outdoor equipment near the coast needs enclosures and hardware that stand up to salt air, and ground-level chargers in low-lying lots or garages should not sit where water collects. Equipment rated for the location costs a little more up front and a lot less than replacing corroded pedestals.
10. Building in the next phase now
The cheapest time to prepare for more chargers is while the trench is open. Running extra empty conduit to future spaces, sizing the new panel for the next phase and leaving room in the electric room costs a fraction of opening the parking lot again later. Ask for the future-ready option to be priced separately so the decision is clear.
A note on incentives
Incentives change often, so check them before relying on them. One example: the IRS says the federal alternative fuel vehicle refueling property credit applies to qualified property placed in service through June 30, 2026, so it no longer covers new installations. Utility programs come and go as well. Ask your tax adviser and your utility what applies today.
What to send for a useful quote
- The number of ports you want now and later, and Level 2 or DC fast.
- A site plan or aerial with the preferred spaces marked.
- Photos of the main service equipment and the nearest panel, with labels readable.
- Whether you want networked chargers, and who will pay for the electricity.
- For condos, the association's EV policy and any unit-owner requests already received.
KRW Electric (EC13012832) prices commercial charging from a site visit, because that is the only honest way to do it. For a single charger at home, see our EV charger installation page. For a workplace, multifamily building, hotel or retail lot, send us the details or call (305) 359-7312 and we will walk the site across Miami-Dade, Broward or Palm Beach.
