Bay Area eases restrictions for "in-law" units

[David Goossens]

I came across this article and had a few thoughts about how it could be used from an investor standpoint. 

1. Build an in-law unit in the backyard and rent out the main house. This would be a house hacking type of strategy where you could get pretty close to living for free depending on how you acquire the property.

2. Build an in-law unit and AirBNB/rent it out. i could imagine this working well for people in the bay area who already own a primary residence, and want to get started in REI. This could probably be built for $15k-$20k depending on the level of finish, and would be a much easier and affordable way to get started, as opposed to buying a second property.

Thoughts? Opinions?
