Adding ADU to currently rented out property

[Jessica Lawrence]

I am starting to research converting a detached garage on my California rental SFR into an ADU. Has anyone done this on a property they are renting out, and not one they live in? (Perhaps not, since I believe the owner occupancy requirement was just voided by legislation that went into effect in CA on Jan 1st 2020.) Would I have to wait for my tenant's lease to be up in order to do the conversion?
