Gama -
Following these guidelines you cite (FHA) brings in the third scenario brought up in post 14 that was a response to the example in post 10. To summarize, there are now three scenarios:
Reporting option 1 - Appraise "as is" with estimated cost to cure to return garage area to its original use and to within compliance of local codes.
Reporting option 2 - Appraise "subject to" via CB3 - hypothetical condition is that the converted garage has been restored to its original use and to within compliance of local codes.
Option 3 - Appraise "as is", including the unpermitted garage conversion as living area or as a living area use and value based on market data within the area.
All are potentially compliant but have varying levels of potential liability. Option 3, regardless of whether or not it need be implemented due to FHA guidelines, appears to be dangerous from a liability standpoint.
One city near Palm Springs was threatening to throw an old lady in jail over a garage conversion.

No appraiser was involved here, but in a scenario where someone had just bought into a similar situation, it seems clear the appraiser would have been vulnerable if he had done anything other than option 2 above. If he used reporting option 1 he better have had that cost to cure figure right. If he had used option 3 he had better get ready to be asked to pay for whatever the city ultimately asked for regardless of whether or not FHA was asking for it to be done this way.
A side note on the term "workmanlike manner" - Once one cites that an area is "deemed safe", or was constructed in a "workmanlike" or "professional" manner they might have taken on a large level of responsibility for the area in question. How one can do that at lender request when it is a 99% or higher probability that as an appraiser they have no professional background, authority, or competency to do so is a real question. Even if they were competent or had the background, why go beyond the pre-printed form language or otherwise take on this potentially huge responsibility. The lenders routinely ask for this language with regard to unpermitted areas and it is a clear case of wanting a patsy available in case something goes wrong.
