Commercial EV charging installation cost in Johns Creek.

The right level follows how long vehicles sit, not how impressive the charger looks. Workplaces and multifamily buildings are usually best served by Level 1 and Level 2, because cars park for hours and slow power is enough. Public-facing sites are where Level 2 and DC fast charging make sense, since drivers want to leave. Getting this wrong is expensive in both directions: too little power strands drivers, and too much power buys electrical work you never use.

There is also a quieter option worth pricing. Instead of a pedestal at every stall, you can install 120/240-volt receptacles and use portable Level 1 or Level 2 units that live in the vehicles. That lowers overall project cost, adds flexibility, and makes replacement simple when a unit fails. Public and retail sites carry a second cost line: turnover only helps you if drivers can pay, so networking and access control belong in that budget from the start.

Hardware has a published range. Everything else is set by your building and your utility, so ask for each line separately instead of one bundled number.

The charger is the easy part of the estimate because it has a price list. The site is the part that decides your budget. Two conditions matter most: how far the stalls sit from incoming electricity, and whether the existing service has room. Distance means trench, conduit, wire, and putting the surface back. No room means panel work or a service upgrade, and the utility has to be in that conversation early, because upgrades and metering changes carry both cost and lead time. Ask for the route on paper. A quote that names the path from the service to the stalls is a quote someone actually walked.

Plan the layout for the count you expect in five years, not the count you are buying today. Pulling conduit once for future stalls is far cheaper than opening the same pavement twice. Networked units also need a reliable wireless connection at the stall, and outdoor equipment has to tolerate weather, so both belong in the site walk rather than the punch list.

One more lever worth pricing: receptacles and portable units instead of a pedestal at every stall. For fleet and staff parking, that trims project cost and turns a failed charger into a swap rather than a service call.

Same chargers, same count, very different invoices. Before you compare bids, work out which column your property sits in, because that difference is what the bid spread is really measuring.

A serious scope starts before hardware. Settle the project scope, budget, funding mechanism, and timeline. Decide the number and type of units you need now and the number you expect later, because that second figure sizes the conduit and the panel. Confirm proximity to incoming electricity, whether metering has to change, where a wireless signal reaches, and how the stalls will be signed and secured. Then assess permitting and inspection requirements, since inspection sequencing often controls the finish date more than the electrical work does.

Pick the contractor with the same care. Federal guidance points site hosts to a certified electrical contractor. In Georgia, EVITP certification is not a blanket state mandate, but it is frequently required on federally funded, utility-program, and public-agency projects, so ask about it early if you expect to use program money. Some organizations, especially public agencies and larger property groups, also have to issue a formal solicitation, which adds weeks before anyone picks up a shovel.

Check incentives in the right order, too. Programs are applied for before construction, not after. Federal 30C charging support is history for property placed in service after June 30, 2026, so build the budget around state, local, and utility programs rather than a federal credit.

Two choices set your cost after the ribbon cutting, and neither one shows up on the equipment quote. The first is who owns the hardware. The second is how you meter, network, and price it. Ownership determines who pays for a failed unit in year four. Networking determines whether you can see utilization, collect payment, and separate charging load from the rest of the building's electricity. It also decides whether you can prove utilization to a lender, a tenant, or a board a year from now. And if you plan to recover cost from drivers, the payment path has to exist before the first session, not after the first complaint.

Phase the project so the expensive part happens once. Trenching, conduit, and panel capacity should be sized for the stall count you expect at the end, even if you energize only a fraction of it now. Adding ports to conduit you already own is a small job. Reopening a lot is not.

Then price the years, not just the install. Plan on up to $400 per charger per year for maintenance, and note that annual extended warranties for DC fast chargers can run over $800 per charger. Level 1 and Level 2 units often carry a fixed-term warranty at lower cost, but once that term ends, repairs land on you.

Energy is its own line. Demand charges are typically driven by the highest 15-minute average use recorded in a billing period, and DC fast charging is far more likely to trigger them than Level 1 or Level 2. Ask whether a time-of-use rate makes overnight charging cheaper, then match your access hours to it.

Finally, write the service expectations into the contract. A maintenance agreement should state a response time, a repair time, and an uptime requirement, because a charger that is down is a stall you cannot rent, staff, or count on.

Bids are only comparable when they break out the same way. Ask every bidder for these five lines, and the cheap-looking quote usually explains itself.
