East Bay Date of Death Appraiser › San Jose Date of Death Appraisal › ADU and Granny Flat Appraisal
An accessory dwelling unit is not automatically worth its construction cost or a fixed amount per square foot. The relevant question is how buyers react to the additional living utility.
Detached cottages, attached additions, garage conversions, and internally connected secondary living areas may provide different levels of privacy and utility.
When adequate data is available, paired sales and other market evidence may help measure the contributory value associated with an ADU or similar secondary living improvement.
Available permit and public-record information should be considered together with the observed physical configuration of the property.
For a Date of Death appraisal, the analysis should reflect buyer reaction to ADUs and secondary living areas as of the historical effective date rather than assuming today's market reaction existed in the past.
