Outdoor, driveway, and detached garage charging
Charging outside is completely normal. It just changes the job from a short indoor run into a wiring project with dirt involved.
Weather rating comes first
An outdoor charger needs an enclosure rated for wet locations, typically NEMA 4 or better, along with in-use weatherproof covers on any receptacle, and UV-stable conduit and fittings. Mount it where snow slides off a roof onto nothing, and where the cable is not lying in a puddle or across a walkway.
Long runs and voltage drop
Distance costs money twice: more wire and thicker wire. Past roughly 75 to 100 feet an electrician often steps up a conductor size to keep voltage drop within a few percent, so a 120-foot run can cost noticeably more per foot than a 30-foot one.
Trenching to a detached garage
Reaching a detached structure usually means a trench at code-required depth, either direct burial cable or conductors in conduit, and often a small subpanel with its own disconnect at the far end. Soft lawn is cheap to dig. Concrete, pavers, mature tree roots, and rock are what blow up a quote — and any digging requires a utility locate call first.
Cheaper alternatives worth considering
Mount the charger on the house wall nearest the parking spot and let a 25-foot cable cover the rest. Or charge nose-in rather than backed in. Relocating the unit by ten feet sometimes removes an entire trench from the job.
Security and cable management
A driveway unit is in public view. Look for a locking holster or a charger that requires app or RFID authorization, keep the cable off the ground on a hook or retractor, and give the area a light so you are not fumbling at the connector in the dark.
Ready for a real number?
An estimate is a planning range. A licensed electrician can look at your panel, your run, and your permit rules and give you a firm price.
