Why Does Running Power to a Detached Garage Feel So Complicated?

Totally get where you're coming from. I used to dream up all these “what if” scenarios too - like, what if I suddenly become a master woodworker with a dozen power tools? Never happened. Now I just run what I need and get creative later if something changes. Saves money, saves sanity... and my garage isn’t a maze of empty boxes anymore. Sometimes less really is more.

Funny, I’ve seen folks wire up their garages for every tool under the sun, only to end up using a single outlet for years. Had a client once who wanted 220V everywhere “just in case” - cost him a fortune and he barely plugged in a shop vac. I get wanting to future-proof, but sometimes it’s just overkill. Curious, did you ever regret not adding more circuits later on? Or did it all work out?

You nailed it - people get carried away with “just in case” wiring. I’ve seen garages with subpanels that could run a small factory, but the only thing plugged in is a battery charger. It’s easy to get swept up in the idea of future-proofing, but unless you’re planning on running heavy equipment or multiple high-draw tools at once, it’s usually unnecessary.

I always tell clients to think about what they’ll realistically use in the next five years. Sure, adding a couple of extra circuits is smart, but wiring for every possible scenario? That’s money better spent elsewhere. Retrofitting later isn’t as bad as people think, especially if you leave a little slack in your conduit or plan for expansion.

Personally, I’ve never regretted not going overboard. A well-placed 20A circuit and maybe a 240V outlet for a compressor or EV charger covers 99% of what most folks need. Anything more tends to just gather dust... or cobwebs.

That’s exactly what I’ve been thinking - sometimes it feels like folks are prepping for a full-on workshop when all they want is a place to charge a drill and maybe run a shop vac. I get wanting to be prepared, but isn’t there a point where the cost just outweighs the “what if” factor? Curious if anyone’s actually had to go back and add more circuits later - was it really that much of a hassle, or did it turn out easier than expected?

Honestly, I used to think the same - just keep it simple, right? But after adding solar panels to my garage roof, I realized a little extra planning up front can save a ton of headaches. Running another circuit later meant tearing up some landscaping I’d just finished... not fun. Sometimes a bit of “overkill” is actually future-proofing, especially if you ever want to plug in an EV or add more tools down the line.
