Hello Michael,I own a company that specialized in building ADU's in Los Angeles and while I can't speak to the demand in your particular zip code what I do know is that each ADU we've built has created an ROI for our homeowners.

Hope no fire hazards or code issues or noise issues or electric shock etc. by doing this project.

can you provide a zip code of an area in Tucson that you are interested in?

Not sure about Georgia, but in Washington we have a revised code that addresses this.

Does the tax code say this directly or is this inferred from the mechanics of the bonus depreciation calculation?

Here you would sell to someone that can run their business form the home or the garage/workshop if that’s allowed by local code. 

The only way to answer that in general (whether house hacking in today's market is still a good option) or for a particular property, is to learn how to run the numbers and analyze a specific property to see whether it will be able to stand on its own as an investment when you move out someday.There are a lot of resources here on BP for doing that but I'd just say, make sure the assumptions you're putting into your spreadsheet or deal analyzer are realistic.Make sure the rents (especially for vacant units or pro-forma #s) are realistic by doing your own rent comps; make sure the mortgage rate is realistic by doing some research online and/or talking to some mortgage folks; make sure insurance #s are realistic by getting a couple of quotes for the # of units and zip code / area you're looking in; etc.I hope that helps, and good luck 😊
