Should I buy a townhome with ADU?

[April Causapin]

Hi! I'm a single professional looking to buy a place in this crazy market. I've looked at a lot of homes with ADU potential. A lot needed work and that's what made me hesitant to purchase them. Interestingly enough, I recently came across a new townhome with ADU (basically a bedroom with a walk-in closet, bathroom (stand alone shower) and a wet bar. I've never seen one set up like that before. It piqued my interest because it would be nice to house hack without the renter entering your actual home. Right now for the plan, the builder will create a separate entrance from the home for the "ADU" on the first floor. The townhouse is a trilevel home. I'm looking into having an extra income while owning my own place and eventually being able to rent the "ADU" and the upstairs area of 2 bed and 2 baths in the future. The "ADU" bedroom is 10'-9" x 10'-10". Asking price is 575k, 8k for ADU conversion of the bedroom downstairs and another 10-11k for solar panels if I decide not to lease it. I live in california by the way. Is this a sound investment or place to purchase? I'm not sure if I can legally rent the ADU as well since there's no actual kitchen. Do I need to provide access to my own kitchen and washer/dryer and garage? Thanks in advace for any advice I may receive from this post.
