@Raphael Schwartz I've been investing in Austin since 2008 and as others have mentioned, it's difficult and expensive to build ADUs in Austin. However, City Council - in a desperate bid to do anything to address affordable housing - has indicated that they want to make it easier to place ADUs in back yard without some of the use restrictions that exist now. I mention this because this means that single family properties that don't necessarily have driveway access to the back yard, but have a back yard large enough to support a small ADU, might be a worthwhile long term play as it would significantly boost rental income on the property. Again, there are all sorts of restrictions about impervious cover, setbacks etc and building costs remain high, so you just need to run the numbers on whether that makes sense to buy a property then invest another $300K in an ADU. Plan on at least $250/sf to build an ADU...if you can find a someone to build it... Other than that, Joe is right that you can't go wrong with most pockets East Austin and South Austin.
