If you park in the driveway or under a carport, the charger has to meet the car somewhere outside. There are three ways to do it: mount it on the house wall that faces the parking spot, mount it on the carport structure, or set a freestanding pedestal next to the space. The right one depends on how far the car sits from the house, what the carport is made of, and whether power has to cross a lawn or a driveway to get there.
This guide covers each option, what trenching and underground conduit involve, the South Florida wrinkles (rock, pavers, sprinklers, water), and what to ask before anyone starts digging. It is part of our Florida Home EV Charging Guide.
Option 1: the house wall
When the car parks within cable reach of the house, a wall mount is almost always the simplest. The circuit runs from the panel along or through the house, and there is no trench. Measure the cable path from the wall to the charge port with the car parked where it really parks, not where it would ideally park. Tesla's Wall Connector ships with a 24 ft cable, and other brands differ. Keep the cable out of the path to the front door, and remember a second car may park in front of the first.
Option 2: the carport
Carports come in two kinds. A carport built as part of the house, with block walls or heavy wood posts, often has a wall or column that makes a good mounting surface, out of the worst rain and sun. A lightweight aluminum carport added later usually does not: thin posts and sheet roofing are not built to carry a charger, a cable hanging off it, and conduit. Tesla says its unit can go on any flat, vertical surface capable of supporting its weight, including a pedestal (Tesla installation considerations). If the carport post is not that surface, a pedestal beside it is the usual answer.
Option 3: a pedestal
A pedestal is a post, usually metal, set in a concrete footing or bolted to a slab, with the charger mounted on it and the conduit coming up from underground inside or beside it. It lets you put the charger exactly where the cars are.
Placement in words: for a two-car driveway with both cars nose-in, a single pedestal centered at the head of the driveway, between the two spaces, can often reach both ports. For a single space along the side of the house, the pedestal goes at the front corner on the charge-port side. In either case, set it back from the edge where cars turn, and add a wheel stop or bollard if a bumper could reach it.
Getting power to a pedestal: trenching and conduit
Underground wiring is governed by NEC 300.5 in the 2020 NEC, which Florida uses through the Florida Building Code 8th Edition. As summarized by EC&M for the 2020 NEC: cables and raceways underground need a minimum cover set by Table 300.5, conductors in underground raceways must be listed for wet locations, direct-buried conductors that emerge from grade need protection from physical damage up to at least 8 ft above ground, and backfill must not damage the raceway or cables.
The required depth is not one number. Table 300.5 gives different minimum cover depending on the wiring method (PVC conduit, metal conduit or direct-burial cable) and the location (open yard, under concrete, under a residential driveway). Cover is measured from the top of the conduit to finished grade, not from the bottom of the trench. Your electrician chooses the method and the depth together, and some building departments want to see the open trench before it is backfilled, so ask yours.
For EV circuits we generally run conductors in conduit rather than direct-burial cable. Conduit protects the wire, lets it be pulled out and replaced later, and makes it easier to upsize for a second charger without digging again.
South Florida wrinkles
Call 811 first
Florida law requires an excavator to notify the one-call system not less than 2 full business days before digging (F.S. 556.105), through Sunshine 811. That locates the lines utilities own. Private lines, such as irrigation, landscape lighting, a pool feed or a line to a shed, are generally yours to find, so tell your electrician what you know about them.
Rock and water
Some lots hit rock before reaching the depth a trench needs, and a high water table can fill a trench quickly in the rainy season. Both change how the trench is dug and can change the wiring method. That is a site-visit question, not a guess over the phone.
Crossing a driveway
- Pavers can usually be lifted, trenched under and relaid.
- Poured concrete means saw-cutting a strip and patching it, or boring underneath.
- Boring passes a conduit under the slab without cutting it, where soil conditions allow.
- Going around the driveway along the lawn is sometimes longer but simpler.
Sprinklers and sun
Aim irrigation heads away from the pedestal and the plug. A pedestal in full afternoon sun runs hot; check the charger's rated operating range (the Wallbox Pulsar Plus, for example, is rated to 104 F per its datasheet). See Florida heat and EV charging.
Low driveways
If the driveway floods in storms or king tides, the charger height and the pedestal's location need more thought. See EV chargers in flood zones.
HVHZ
In Broward and Miami-Dade, ask the building department whether the pedestal's footing or anchorage needs product approval or engineering. We raise it at permit time.
Choosing the charger for an outdoor spot
Outdoor and pedestal chargers take rain, sun and, near the coast, salt. Look for an outdoor rating (the Wallbox Pulsar Plus and Emporia Classic list NEMA 4; Tesla's Wall Connector is Type 3R) and read outdoor chargers in rain and salt air for what those ratings mean. A hardwired unit avoids an outdoor receptacle entirely.
| House wall | Carport | Pedestal | |
|---|---|---|---|
| Trench needed | No | Sometimes | Usually |
| Weather exposure | Depends on overhang | Partly sheltered | Fully exposed unless covered |
| Best when | Car parks close to the house | Carport has a solid wall or column | Cars park away from the house |
| Main cost drivers | Distance to the panel | Mounting surface, route to the panel | Trench length, what it crosses, footing |

What to ask before digging
- Where exactly will the pedestal or unit sit, and can the cable reach both cars?
- What wiring method and depth will the trench use, and why?
- How will the trench cross the driveway or walkway?
- Who calls 811, and what private lines are in the path?
- Will the building department inspect the open trench?
- Will the conduit be sized for a second charger later?
- How is the pedestal anchored, and is anything needed for the HVHZ?
Questions homeowners ask
Can I run an extension cord to the driveway instead?
Not as a permanent setup. A cord across a driveway gets run over, tripped on and soaked in afternoon storms, and an EV draws a heavy current for hours at a time, which is not what a household extension cord is made for. Check what your charger's manual says about cords. If the car cannot reach an outlet, the answer is a properly installed circuit.
How deep does the trench need to be?
It depends on the wiring method and where the trench runs, under the NEC 300.5 rules summarized above (EC&M summary). Your electrician should tell you the method and depth, and the inspector checks it.
Can the pedestal go on the lawn?
Yes, on a proper footing. Keep it out of the mower's path and the sprinkler spray, and put it where the cable does not lie across grass the car will drive onto.
Will my HOA or condo allow a pedestal?
Many HOAs control exterior changes through their governing documents. Condo owners have specific rights under Florida law. See Florida HOA EV charger rules and condo EV charger installation.
Parking outside and want to charge at home?
KRW Electric (license EC13012832) installs home chargers on walls, carports and pedestals across Miami-Dade, Broward and Palm Beach, and handles the permit and inspection. See our EV charger installation page, then send us photos of the driveway and the panel or call (305) 359-7312.
