We're working on planning for one right now—doing it to provide extra income from our property. We're simply converting a 2-car garage, adding no extra square footage. Estimates we've received range from $125K-$150K. These are from companies that do the whole project from design and permitting all the way through to your occupancy cert. These prices also include all finishes and appliances (cabinets, vanity, shower enclosure, stove, hood, fridge, W&D, mini-split, tankless hot water heater, etc.), basically providing a rent-ready space.
There seems to be some specific issues that come up for permitting an ADU (i.e. DWP Encroachment) and getting it approved so I'd recommend using someone with specific ADU experience. A lot of builders are jumping on the bandwagon because so many people want them right now as the City of LA is favorable to them to increase housing inventory.

YouTube has a lot of video walk-throughs and advice for garage conversions to get a feel for layouts, looks, and process. I'm pleasantly surprised how spacious and nice of a space a garage can be turned into.
Wow, those are definitely some good resources, I am going to check these out! Thank you!
