Where to put the chargers in a parking lot
Put them as close to the electrical service as the site allows, then move them only as far as the accessible route and vehicle protection force you to. Three constraints intersect at the pedestal and they pull against each other: distance from the power, because conduit and the trench that carries it are the single largest line item on most lot projects; the accessible route and the space geometry, which are code and are not negotiable after the fact; and survivability, meaning vehicle strike, snow storage, plow paths and drainage. The visible spot by the front door is usually the most expensive spot on the property, because it is normally the furthest from the switchgear and the most disruptive to reach. Sometimes paying for it is still the right call, and the test for that is whether the charger is doing a marketing job or an amenity job.

Start at the service, not at the front door
Almost every dollar of variance between two otherwise identical charger installs is the distance between the power source and the pedestal, and what the route crosses to get there.
The accessible route is a location decision, not a sign
Accessibility constrains where the pedestal can physically stand, and it is far cheaper to honour at design stage than to retrofit after the concrete is poured.
Cable length is a hard limit people discover late
The NEC caps the usable length of an EVSE output cable at 25 feet unless the equipment has a cable management system, and that single number decides how many spaces one port can plausibly serve.
Survivability: what will hit it, freeze it or flood it
A pedestal in a parking lot lives in a hostile place, and most of what goes wrong after year one is mechanical rather than electrical.
When the expensive spot by the door is the right one
Visibility is worth paying for when the charger's job is to be seen, and worth nothing when its job is to charge cars belonging to people who already live or work there.
Ranking a candidate location in ten minutes
Walk the lot with this list and the shortlist usually collapses to two options, both of which an electrician can price.
Should EV chargers go in the best parking spaces?
Only if the charger's job is to be seen. For an amenity serving residents, employees or guests who already know the ports are there, prime placement buys nothing and costs the longest conduit run on the site. For a retail or hotel property using charging to attract people who have not arrived yet, visibility is the point and the run is part of the advertising budget. A directional sign at the entrance splits the difference for a fraction of the cost.
How far can an EV charger be from the electrical panel?
There is no code limit on distance, only on voltage drop and conductor sizing, and both of those are solved with money. The NEC's commonly cited guidance — three percent drop on the branch circuit, five percent overall — is an informational note rather than an enforceable rule, but designers work to it. Practically, past a few hundred feet it is often cheaper to set a sub-panel near the pedestal group than to upsize a long homerun.
Do EV chargers in a parking lot need bollards?
Usually, and the requirement comes from two places rather than one. The NEC requires equipment likely to be exposed to physical damage to be guarded well enough to prevent it, and the equipment's own listing and installation instructions frequently specify protection. What that means at your site is set by your authority having jurisdiction and by the manufacturer. Ask both before the footings go in, because retrofitting bollards means cutting new concrete.
How many parking spaces can one charging port serve?
Two, in almost every workable layout. The NEC caps EVSE cable at 25 feet of usable length unless the unit has a cable management system, and that length has to reach an inlet that might be on any corner of the car. A pedestal centred between two stalls serves both. Stretching it to three produces a cable draped across a stall, which is a trip hazard and a short cable life.
Where should chargers go in a lot that gets snow?
Out of the snow-storage corners, which is where a plow operator pushes accumulation, and away from the low point the lot drains to. Both are decided by people who already know the answer: the snow contractor and whoever holds the grading plan. Mark the pedestals with something taller than the equipment so they are visible above a windrow, and put the requirement in the snow contract rather than assuming it.
Can we add more chargers later in the same place?
Yes, and the way to make that cheap is to pull spare conduit while the first trench is open. The excavation and restoration are the expensive parts; the marginal cost of extra ducts in an open trench is small. Size the pad, the feeder and the conduit for the port count you expect in five years, and populate the ports you need now.

Price two locations instead of arguing about one
The estimate takes the distance from your service, the surface the route crosses and the port count, and gives you a range for each candidate spot. Running it twice is the cheapest way to find out what the front-door location really costs.
