If cost /= value then it doesn't really matter how much they spent. With that said, I highly doubt Marin County would tolerate any unpermitted work. The public records already reflect the larger GLA so that's usually an indication to the legitimacy thereof. Subject to the exception to the rule, of course.
If we were doing a 2055 on this property then we would work off the assumption the public records entry was significantly correct. I'm sure the buyers and brokers in the market would do the same.
This property wouldn't have been any easier to appraise in its original GLA than in the larger size. The primary difficulty with any appraisal being performed in that neighborhood in 12/2020 remains the same - no recent sales.
