Is there a wall they can run a conduit on to the garage? If not they'd have to trench and bury the conduit underground. Can get pricey especially if concrete is in the way.
I don't see any, but this is a good idea. I think the installer would either go outside from the bathroom or in to the ceiling and out to the patio and then in to the garage. I'm not sure how he would get from the patio to the garage...maybe through the wall I guess?
Going through the walls isn't too difficult. You can't run conduit in air however, it has to be attached to a structure. If your garage is fully detached your options are reuse existing wiring if you indeed have 2 circuits in the garage (count breakers for the garage on the panel) and live with 12-16A/240V charging, pull new wires through the existing conduit if there's one and install a subpanel in the garage, or trentch to bury a new conduit + possibly subpanel.
My garage is considered 'attached', but it's attached to a small patio. Unfortunately, the panel box is in the downstairs bathroom, but at least it's downstairs! They really weren't thinking much about this in 1990, were they? It's also a 100a panel box so there's some headroom there for a 40a dedicated circuit for the 32a Chargepoint charger.
I'm dealing with a Tesla-recommended contractor (Chamberlin) who specializes in more difficult installations in condos and townhomes, and he's highly-rated (down in Long Beach). I have another contractor coming out to bid tomorrow (A&G) and is also highly-rated. I used HomeAdvisor to find contractors to allow self-selection out of what might be too tricky for some looking for a more straightforward installation.
As mentioned, I've gotten some wildly different opinions, from 'impossible' to crazy expensive bids, to much more reasonable contractors willing to tackle this job seriously (without price-gouging). I'm no electrician but I'm a pretty good skeptic.
Thanks for the feedback and advice!
