How are ADU's currently being appraised in Los Angeles? After SB 9 was passed.

Wade Barnett
Posted

I'm an investor based in Los Angeles and I'm planning on building a detached 2 bed 2 bath ADU (garage conversion) on my home to house hack, and eventually will rent out both units. I have done this once before (in Cypress Park, Los Angeles), and had some issues getting a fair appraisal. The first appraisal only gave me I think 50k in value for the ADR/garage conversion. I waited for better comps, and got it reappraised once it was being rented out, and I could provide proof of rental income to the appraiser, and it appraised for much more. But this was back in late 2020 when the market was appreciating very quickly. My question is if anyone has experience more recently after SB 9 passed, if appraisers are actually valuing ADU's for their actual worth? How can an appraiser only add 50k to the value of a home that has an added 2 bedroom 2 bathroom 850 square foot detached ADU that rents for 3700 a month? The ADU brings in almost 50k in rental income every single year. I mean that makes no sense at all.

I would love to hear from Appraisers, or any investors that have dealt with this more recently in Los Angeles, or in California. I know in the past getting fair comps with ADU's was more difficult. But I'm hoping since ADU's are getting more common, and since SB 9 is providing more clarity on the subject, that ADU's will start to get appraised more realistically. If not I'm wondering what formula Appraisers use when factoring in rental income in terms of adding value to the home. It seemed like the last time I had success, it was the rental income that helped the appraiser give fair value to the ADU.

Thanks,

Wade

The value of properties with less than 5 units is unrelated to the income (rent, NOI, etc). It is based on comps. The fact that you had incoming rent should not have changed the value from an appraisal. What I suspect happened is that there were higher comps of homes wiht ADUs than were available for your initial appraisal post adding ADU.

ADUs likely will not ever value at the same as the hands off cost because more buyers want SFH than want "duplexes" (SFH with ADU is not really a duplex but it has the sane disadvantages as a duplex for occupants). If someone wanted an ADU, they can add an ADU at the hands off cost.

In addition, PSF is significantly based on land cost. The land did not increase in value. For example my home appraised in Dec 2021 as $630 PSF (it would appraise for more now). The home costs no where near $630 PSF. The majority of that value is the land value. This implies that it is unreasonable to expect the ADU to add the same PSF as the primary structure would by itself because the land and its value is now shared.

The market will dictate the value assigned to ADUs especially when more comps are available, but to expect the market to ever fully reflect the hands off cost to add an ADU is unrealistic for the reasons cited.

Good luck
