Reasonable to turn a garage into a STR to house hack in Austin?

[Robert Johnson]

I'm exploring the idea of buying a single-family home in South Austin and turning the garage into a self-contained living space that I would live in and rent out the main house. The idea would be to use that space as a STR after I moved out. I'm curious if there are experienced investors in Austin that can tell me how complicated the process would be to do this in terms of permits, zoning, etc. Also, any general ideas about this strategy in general.
