Totally get where you’re coming from—what starts as “just a quick job” always seems to snowball into a full-on electrical deep dive. Those voltage drop charts have a way of making your brain hurt after a while. I’ve seen plenty of folks go all-in with outlets every two feet, subpanels, the works, and then realize they only ever use half of it. Nothing wrong with planning ahead, but honestly, most garages don’t need to be wired like a small factory.
Recycled conduit is a smart move—saves money and keeps stuff out of the landfill. I do like the idea of leaving things open for tweaks down the line. One trick I’ve picked up: run an extra pull string in your conduit if you can, even if you think you’ll never need it. Trust me, future-you will thank past-you when you want to add something later.
Simple setups are underrated. As long as it’s safe and meets code, you’re usually better off keeping it straightforward unless you know for sure you’ll need more juice down the road.
I get the appeal of keeping it simple, but I’ve actually regretted not going a little bigger on my last garage project. Ended up adding a mini split and a 240V outlet for tools a year later, which meant tearing into finished walls—total pain. Sometimes “overkill” just means you’re ready for whatever comes up. Not saying everyone needs a subpanel, but leaving room for upgrades can save a lot of hassle down the line.
I get where you’re coming from, but honestly, I’ve seen way too many people go overboard “just in case” and end up wasting money on stuff they never use. Not everyone’s gonna need a subpanel or a 240V line, especially if you’re just parking cars and storing some junk. I usually stick with what I know I’ll need for the next couple years, and if things change, yeah, it’s a pain to upgrade, but at least I’m not out a bunch of cash up front.
Last place I flipped, the previous owner had wired it for every possible scenario—EV charger, welder, even a hot tub hookup. None of it ever got used. Sometimes simple really is better, unless you’re dead sure you’ll need the extra juice. Just my two cents.

I know exactly what you mean. I once helped my brother-in-law with his garage and he insisted on running a 100A subpanel “just in case” he wanted to get into welding or buy an electric car. Fast forward five years, and the fanciest thing he’s plugged in is a mini fridge and a shop vac. Meanwhile, he gripes about how much the wire and panel cost him.
That said, I’ve also seen the opposite. My neighbor only ran a single 15A circuit for lights and a couple outlets, then ended up kicking himself when he bought a table saw and couldn’t run it without tripping the breaker every time. He had to dig up the trench again to upgrade, which was a nightmare.
I guess it’s a bit of a gamble either way. I lean toward running a little extra capacity—maybe not full-on “future-proof everything,” but enough headroom that you’re not stuck if you want to add a freezer or some heavier tools down the line. Overkill isn’t always the answer, but being too conservative can bite you too.
I hear you on the overkill vs. underkill thing. When I ran power to my own detached garage, I was determined not to break the bank but also didn’t want to regret it later. Here’s what I did: figured out what I actually needed—lights, a couple outlets, and maybe a small air compressor. I ran a 30A circuit, which was plenty for my setup and left a little wiggle room. Didn’t bother with a subpanel or anything fancy.
My neighbor went all-in with a 60A subpanel “just in case” he wanted to put in a kiln or something. Two years later, he’s still just charging his drill batteries and using the space for storage. Meanwhile, he spent three times what I did.
Honestly, unless you’re dead set on heavy equipment or an EV charger soon, I’d say plan for what you’ll actually use in the next few years. If you do end up needing more juice down the line, yeah, it’s a hassle, but at least you didn’t overspend upfront. Sometimes “future-proofing” just means paying for stuff you never use.
