Allowable to purchase a primary with a detached ADU, cost seg just the ADU

[William C.]

Wild idea based on a property in my local market. Is it allowed to purchase a property with our primary home that has a detached ADU on the same tax lot. Live in the primary. Rent out the ADU as a STR (7 day stays or less). Perform a cost seg study on JUST the ADU. Anyone out there with experience in a similar situation? Thanks for taking a look.

Yes. This is common in California
