Supply isn't changing, but demand is now increasing even more than it was before. 

The LP investor goes through the website, supplies documents and gets verified or not.

It has a lifespan, like anything else.Looks like a lead supply line too. 

@Henry ClarkThank you for reaching out with the HUGE amount of info and direction you have supplied.

You do not want to try and manage projects yourself and supply materials especially if you have little to no experience.

This area of Austin is short on supply and homes sell very quickly.

It has 4 tenants: an MMA gym, art studio, beauty supply shop and recently moved in hair saloon (currently renovating still).

@Justin G.Thanks Justin, just read your bio and I’m actually majoring in finance and supply chain as well.

I supply appliances to my tenants.

Very hard to tell from your photo, but assuming that is not the drop to your property but one of LADWP's supply lines (there would be an utility easement on your property) then yes it may be impossible to have a 2 story ADU as there are clearance issues, both lateral and height wise.
