Having installed these in many different spaces (not really an active business these days just do it for family and friends or myself), one of the biggest problems is garages are being designed so much smaller these days. Often I was limited by what others have said here getting in and out of your vehicle and around the front and back of it. If it’s not built yet, you can have the builder plan for some extra space for those kind of things and still park vehicles in there that you can move out when you wanna work on something.If already planned out or built and you’re going to be using any of that to park a car, that has to be considered. If you have a third bay or one you’re never going to park in, you have a lot more latitude on depth and location of cabinets. Not a real problem for selling it later on or anything like that or even if you change your mind because these cabinets that mount on the wall come off in literally minutes and are completely relocatable or sellable. They do not even have backs inside if you get the Slide Lok and a few other brands. No real need to heavily fortify the wall behind them if it is regular construction 2 x 4 or 2 x 6. It is amazing how much weight you can hang on a wall when it is attached to studs in three or four places inside. All the forces are sheer forces up and down very little rotational force away from the wall unless you load extreme weight in the very deep cabinets. A number of my 2 foot deep cabinets are full of heavy steel jackstands and other items and it is no problem.
Also, be sure to locate electric and water lines so you don’t put a screw into one of them as they pass them through a stud. I know that from experience once or twice and had to pay for repairs. I plumbed in Airlines behind the walls and put connection ports all the way around the perimeter. Stuck one in the middle of the ceiling and put a roll down air cable on it that reaches the whole shop. I don’t think I’ve ever used one of those that I plumbed into the wall since I built it because the one hanging from the ceiling is so much easier to grab and go with. Same is true with electrical receptacles there all the way around, but I still use the big real hanging from the ceiling 80% of the time
Sorry if I went on and on, some thing I enjoyed doing on the side for years and it is nice to have everything behind doors. Allows for a lot cleaner storage of products and parts. Everything off the floor I can clean it out with a leaf blower or garden hose and no sweat.
