Not all people have high standards, or the skills, or the knowledge. 

Somewhere between $3,000 - $5,000 is pretty standard.

I can't imagine one of these fitting into a standard house, unless it was a ranch with a near direct shot to the bathroom.

The most pressing, and i cant seem to find a true answer from the the building department OR the utility companies is if I need to have separate meters (Electrical, gas, water) for my ADU and main home. 

Obviously if the difference between a standard LTR and a STR/MidTerm is that different, I would highly consider it, but I'd have to study up on all the extra variables of what an STR entails.

Hi all, Recently my SF rental property had some pipes freeze and burst, causing a considerable amount of water damage to the house.

The HOA covers all water, flood and building insurance, internet, bug spraying etc. and it's $1562 a month.

For water maybe some sort of large reservoir and have water trucked in?

I saw a lot of potential even though there was much deferred maintenance, poor mgt. and significant water damage in one unit requiring complete rehab.

You need some descent reserves to be a larger landlord, because you don't get a choice when the AC unit goes out, or the hot water heater floods the upstairs unit that then floods the downstairs unit.
