When building, you have more control of the design, layout, materials, and overall use of the ADU. 4.

I also just go to Newest Posts.I have to agree the traditional forum layout is probably the best way.

And you can apply this to just about anything; granite counter tops, odd layouts, bedroom and bath counts, etc. 

I know they will depend largely on the layout of the house, the existing plumbing, amongst other things.

Look for houses/townhouses with a "roommate" layout -- at least one bathroom per bedroom -- so shared areas are only kitchen, laundry and dr/lr.  2/2.5s are pretty easy to come by for relatively decent prices in Atlanta, or 3/2.5 (sometimes 3 full bath) townhomes are also plentiful. 

If someone is going to trust me with tens of thousands of dollars, I need to lay out a very strong case in my business plan!

I toured a 12 unit property where the numbers looked good, I liked the location and layout, but I found out that the whole thing was constructed with 2x4's.

.-100 HVAC units vs 10-100 roofs vs 10-100 layouts vs 101 size door and few size window instead of hundreds.   1 property bill instead of hundreds. 

It’s a small (just shy of 700 sq ft) 2bd/1ba that has layout that leaves a lot to be desired.

City doesn’t know the layout so there’s no need to get any permits They already think that a bonus room is the second bedroom.
