A Practical Guide to Appraising Accessory Dwelling Units (ADUs)
By Freddie Mac
Excerpts: Sample Topics:
Appraisal Considerations:
Firstly, an appraiser can’t simply ignore an ADU. If the determination is made that additional finished area qualifies and meets the definition of an ADU, there are some practical steps the appraiser must take in the analysis.
Appraisal Development:
The appraiser will need to determine any effect the ADU has on the market value or marketability of the subject property. The appraiser’s analysis must be documented in the appraisal report and conclude whether an adjustment is supported for the ADU (remembering that the conclusion for no adjustment also requires market support).
Allowable Flexibility:
A good best practice for any appraiser is to reference and use Freddie Mac resources and published appraisal guidelines, which detail the steps an appraiser may take when valuing a property with an ADU. If a subject property ADU complies with zoning and land use requirements, the appraisal report must include at least one comparable sale with an ADU. If not available, then the appraiser may consider an older sale from the subject’s market or a competing market. The appraiser may also expand the search and comparison beyond just three sales, including pending contract sales or listings to justify the support for adjustments.
