Constructing ADU in Tucson AZ?

[Mike Gordon]

I own a property in Tucson AZ that's on a large lot with plenty of room to build an ADU. The city passed an ordinance a few years ago to allow ADUs without zoning laws, so I think it's easy to get ADU construction approved.

My question is about cost. What's a cost effective way to build an ADU so that the return on the rent will make sense? I've seen prices between $100k-$250k as I've researched it. At the low end it makes sense. At the high end it doesn't.

How do you go about this? Does pre-fab work? Buy plans and hire a construction company? How much are utility hookups? Anyone with advice or experience with building an ADU and renting it for STR/LTR?

Tucson recently had a "competition" for ADU's, and are providing the plans for free online.

I guess the idea was to lower some of the costs as long as there's not much deviation from their pre-approved plans.
