Installing EV Chargers During Your Garage Remodel

Every few months, we get a call from a homeowner who just finished a beautiful garage remodel—new flooring, fresh drywall, extra storage, the works. And then they realize they forgot to run the wiring for an EV charger. The drywall is up, the concrete is sealed, and now they’re looking at cutting into brand new surfaces or running an ugly extension cord across the floor. It’s a gut punch, and honestly, it’s one of the most common oversights we see.

If you’re planning a garage remodel in 2026, the timing for adding an EV charger has never been better. Most new homes in the Bay Area are already being built with EV-ready panels, but older garages—especially in neighborhoods like the ones around Lake Merritt or the older tracts near San Leandro—often need significant electrical upgrades. The good news is that doing this work during a remodel saves you money, time, and a lot of headaches. The bad news is that if you don’t plan for it, you’ll be kicking yourself later.

Key Takeaways:

• Adding a Level 2 EV charger during a garage remodel can cut installation costs by 30–50% compared to retrofitting later.
• The biggest mistake is assuming your current electrical panel can handle the load—most 100-amp panels in older San Leandro homes will need an upgrade.
• Running conduit and wiring before drywall goes up is the single most cost-effective move you can make.
• Not every charger is right for every home; you need to match the charger to your driving habits, panel capacity, and local permit requirements.

The Real Cost of Waiting

Let’s talk numbers, because this is where most people get tripped up. A typical retrofit installation of a Level 2 EV charger in an existing garage—where you’re fishing wires through finished walls, cutting drywall, patching, and painting—runs anywhere from $1,200 to $2,500 in the San Francisco Bay Area. That’s just for the electrical work, not counting the charger itself or potential panel upgrades.

Now compare that to doing it during a remodel. If the walls are open and the electrician is already running new circuits for lights, outlets, or a subpanel, adding a dedicated 50-amp circuit for an EV charger might cost you an extra $200 to $500. The labor is already there. The conduit and wire are already on site. You’re paying for materials and maybe an hour of extra labor.

We’ve had customers tell us they wished they’d just spent the extra $300 during the remodel instead of paying $1,800 later. One guy in the San Leandro hills had to have his drywall cut open in three places to run the wire. He was not happy.

What Most People Get Wrong About Their Electrical Panel

This is the part that catches everyone off guard. You look at your panel, see a couple of empty breaker slots, and think you’re good. But a 100-amp panel in a house built in the 1950s or 60s—which is a lot of the housing stock around San Leandro—is already running close to its limit. You’ve got the kitchen, the HVAC, the water heater, maybe a pool pump or a workshop. Adding a 50-amp continuous load for an EV charger can push it over the edge.

The solution isn’t always a full panel upgrade. Sometimes we can install a load management device that automatically throttles the charger when other appliances are running. Or we can add a subpanel in the garage if the main panel has the physical space but not the capacity. But you need an electrician to do a load calculation, not just guess.

During a remodel, this is the time to upgrade to a 200-amp panel if you need it. The electrician is already pulling permits, the drywall is open, and the cost of a panel upgrade is partially offset by the fact that you’re not paying for a separate service call later. In San Leandro, permit fees for electrical work are relatively straightforward, but you still need them—especially if you’re adding a new circuit for a high-load device.

Panel Upgrades vs. Load Sharing

If a full panel upgrade feels like overkill, load sharing devices like the DCC-10 or the NeoCharge Smart Splitter can let you share a circuit between your EV charger and another appliance, like a dryer or water heater. These are great for homes where you don’t drive every day and can charge overnight. But they’re not perfect. You can’t run both appliances at the same time, and some homeowners forget to switch back, waking up to a cold shower and a dead car.

We’ve seen both work well, but the cleanest solution—especially if you’re already remodeling—is to just upgrade the panel. You’ll thank yourself later when you add solar, a heat pump, or a second EV.

Choosing the Right Charger for Your Garage

The market is flooded with Level 2 chargers, and honestly, most of them do the same thing. But there are real differences that matter depending on your situation.

Hardwired vs. Plug-In

Hardwired chargers are permanently connected to the electrical system. They’re cleaner, more reliable, and often required by code in some jurisdictions. Plug-in chargers use a NEMA 14-50 outlet, which is the same outlet used for electric ranges. Plug-in is easier to swap out later, but the outlet itself can be a failure point. We’ve seen outlets melt under continuous high-load charging, especially cheap ones.

For a garage remodel, we usually recommend hardwiring. It’s one less thing to worry about, and it looks cleaner on the wall.

Smart Chargers vs. Dumb Chargers

Smart chargers let you schedule charging, monitor energy usage, and sometimes integrate with your home energy management system. They’re great if you have time-of-use rates from PG&E and want to charge only during off-peak hours. Dumb chargers just work—plug in, charge, done.

Here’s the trade-off: smart chargers cost more upfront and sometimes have connectivity issues. Dumb chargers are cheaper and bulletproof. If you’re the type of person who sets a timer on your phone, a dumb charger is fine. If you want to geek out on energy data, go smart.

Charger Power Levels

Most Level 2 chargers offer 30 to 48 amps. A 48-amp charger on a 60-amp circuit will charge most EVs from empty to full in about 6 to 8 hours. A 30-amp charger on a 40-amp circuit takes closer to 10 to 12 hours. For most people, 30 amps is plenty if you charge overnight. But if you have a long commute or a larger battery (like a Tesla Model S or a Ford F-150 Lightning), the extra speed might matter.

We usually tell people to install a 50-amp circuit with a 40-amp charger. That gives you a good balance of speed and cost, and it leaves room for future upgrades.

Permits, Codes, and the San Leandro Reality

This is the part nobody likes, but it’s unavoidable. In San Leandro, any new circuit for an EV charger requires a permit. The city inspects the work to make sure it meets the current California Electrical Code, which includes things like GFCI protection for outdoor or garage outlets, proper conduit sizing, and clearance around the charger.

Some homeowners try to skip the permit to save money. Don’t. If you ever sell the house, unpermitted work can kill a deal. And if something goes wrong—like a fire—your insurance might not cover it. We’ve seen it happen.

During a remodel, the permit process is already underway, so adding the charger is just a line item on the same permit. It’s cheap insurance.

Where to Put the Charger in Your Garage

This sounds simple, but we see it messed up all the time. People install the charger on the wall closest to the panel, then realize their car has to park diagonally to reach it. Or they put it on the back wall and have to run the cable over the hood every time.

Think about how your car actually parks in the garage. Is the charge port on the front, rear, or side? Most Teslas have the port on the driver’s side rear. Most Chevy Bolts have it on the front driver’s side. Nissan Leafs have it on the front center. Measure where the port will be when the car is parked, then mount the charger within easy reach.

Also, consider the cable length. Most chargers come with a 20- to 25-foot cable. That’s usually enough, but if you have a three-car garage or park at an odd angle, you might need a longer cable or a different mounting location.

Future-Proofing for Two EVs

If you think you might add a second EV in the next few years, run conduit for two circuits now. The conduit is cheap, and running it during the remodel costs almost nothing. Later, you just pull the wire and install the second charger. Without the conduit, you’re cutting drywall again.

Common Mistakes We See

• Forgetting about the panel location. If the panel is in the basement on the opposite side of the house, the wire run can get expensive. During the remodel, you might consider moving the subpanel into the garage.
• Using the wrong outlet. A standard 120V outlet won’t cut it for Level 2 charging. You need a dedicated 240V circuit.
• Not accounting for the charger’s physical size. Some chargers are bulky. Make sure you have enough wall space and that the charger doesn’t interfere with cabinets, shelving, or the garage door opener.
• Skipping the permit. We already covered this, but it bears repeating.
• Assuming you can just use an extension cord. You can’t. Extension cords aren’t rated for continuous high-load charging and are a fire hazard.

When a Professional Is Worth Every Penny

Some homeowners are handy and want to DIY the electrical work. We get it—labor is expensive. But here’s the thing: EV charger installation involves high voltage, continuous load, and specific code requirements. One mistake can fry your car’s charging port or start a fire. In San Leandro, the inspection process is thorough, and if you fail, you’re on the hook for fixing it.

We’ve seen DIY jobs where the wire gauge was too small, the breaker was mismatched, or the ground was missing. Every single one of those had to be ripped out and redone by a licensed electrician. The cost of the DIY attempt plus the redo was more than just hiring a pro from the start.

If you’re confident in your skills and you’ve done electrical work before, go ahead. But if you’re unsure, hire someone. It’s not worth the risk.

The Bottom Line on Timing

If you’re remodeling your garage, add the EV charger now. The incremental cost is small, the convenience is huge, and the resale value of a home with an EV-ready garage is higher—especially in the Bay Area, where electric vehicle adoption is already above 20% in some neighborhoods.

At Modern Green Constructions in San Leandro, CA, we’ve done enough of these to know that the people who plan ahead are the ones who sleep easy. The ones who don’t are the ones calling us six months later, asking if we can cut into their new drywall without ruining the paint job. We can, but it’s never as clean as doing it right the first time.

The table above tells the story. The remodel install is the cheapest, fastest, and cleanest option by a wide margin.

Final Thoughts

Adding an EV charger to your garage remodel isn’t complicated. It just takes a little forethought. Talk to your electrician early, decide on the charger type, and make sure the permit covers the work. It’s one of those rare home improvement decisions where the smart choice is also the cheaper choice.

If you’re in the San Leandro area and planning a garage remodel, we’ve seen enough garages to know what works and what doesn’t. Drop us a line if you want to talk through the specifics of your setup. Otherwise, just don’t forget to run that conduit before the drywall goes up.
