Detached ADU Post-Build Appraisal Value

[Caleb Lee]

Hi BP! I've finished my detached ADU (732 sqft, 2br/2ba) in Los Angeles and now I'm looking into the post-build appraisal value to determine whether to hold or sell. I've seen a bunch of different ADU posts from 2020-2021 showing that appraisers were previously giving very little to ADUs and treating them as an amenity like a pool house or home office, rather than as fully livable, rentable square footage.

I've also heard that with the passage of SB-9 in CA, this effectively makes every single R-1 zoned SFH lot effectively into a duplex-able lot, which could unlock the potential for these SFH + ADU properties to be treated as duplexes for the appraisal, which would result in more favorable ADU valuations.

Anyone seen any favorable appraisals that they'd be willing to share?
