Totally agree—future-proofing is key. I’ve lost count of how many times I’ve had to go back and upsize a feed because someone wanted to add a welder or EV charger later on. It’s not just about outlets and lights anymore. Even if it feels like you’re going overboard, it’s way cheaper and less hassle than digging up your yard again. And honestly, heavier wire isn’t that much more to buy upfront. Just makes sense.
I get where you’re coming from, but I’ve seen folks go a little too far with future-proofing and end up spending way more than they needed. Not everyone’s going to want to run a welder or install an EV charger down the line. Sometimes, people just want a few lights, a garage door opener, and maybe a fridge out there. In those cases, running heavier wire and putting in a big panel can be overkill, especially if budgets are tight.
There’s also the code side—oversizing can sometimes cause confusion or even issues with inspectors if it’s not justified. I usually recommend talking through what’s realistic for the next 5-10 years instead of planning for every possible scenario. Sure, digging up the yard again isn’t fun, but sometimes it’s better than overspending upfront on something you might never use. Just my two cents from being on both sides of these jobs...

That’s kinda where I landed too. I got all hyped up reading about “future-proofing” and almost went wild with a 100A subpanel for my tiny garage. Ended up just running enough for lights, outlets, and the opener. If I ever need more, I’ll deal with it then… but right now, my wallet’s happier.
I get where you’re coming from. There’s always that temptation to go all-in and “future-proof” everything, especially when you see all those YouTube garage tours with 240V outlets everywhere and enough power to run a machine shop. But honestly, most of us just need some lights, a few outlets, and the opener like you said. Unless you’re planning to weld or run a kiln out there, it’s probably not worth the cost or hassle up front.
I did something similar a few years back—dug a trench, ran 12/2 UF cable for a couple circuits, and called it good. At the time, I was convinced I’d regret not going bigger, but so far, it’s handled everything I’ve thrown at it. And if I do ever decide to get serious about woodworking or buy a big air compressor, well... I’ll cross that bridge (and maybe dig that trench) when I get there.
One thing I will say: I kind of wish I had added a conduit instead of direct-bury cable. It would’ve made upgrades way easier down the line. Live and learn, right? But yeah, sometimes it’s better to keep things simple and avoid over-engineering for “someday” scenarios that might never happen.
Also, the cost difference can be wild. When I priced out heavy-gauge wire and a subpanel, my budget laughed at me. Keeping it basic just made sense. And honestly, I think a lot of the “future-proofing” advice out there is based on edge cases or people with way more ambitious plans than most of us have.
All that said, I totally get the urge to go big. There’s something satisfying about knowing you’ll never have to touch that project again. But for most garages? Lights, outlets, opener, and call it a day. Your wallet (and your back) will thank you.
- Totally agree on the conduit vs. direct-bury cable—future-you will always thank past-you for that one.
- Most folks don’t realize how much overkill is out there. Unless you’re running a full-on workshop, 20A circuits and a few outlets are usually plenty.
- I’ve seen people spend thousands prepping for “someday” tools that never show up.
- If you ever do need more juice, it’s not the end of the world to upgrade later (just a bit of dirt and sweat).
- One tip: always label your circuits clearly. Saves a ton of head-scratching down the road when you forget what’s what.
- And yeah, your wallet will definitely appreciate keeping it simple... unless you’re secretly planning to open a Tesla charging station in there.
