An appraiser is completing a condition analysis for a 1958 ranch-style residence with original plaster walls, hardwood floors, and a masonry chimney with unlined flue. The chimney has efflorescence and spalling brick above the roofline, and the flue has never been lined or inspected. Local code now requires stainless-steel flue liners for all wood-burning appliances. What is the appraiser’s reporting obligation under USPAP Standards Rule 1-2 and Advisory Opinion 11?

Option A: Note the unlined flue as a safety hazard but exclude it from value impact analysis unless the client requests it.

Splitting disclosure from analysis is the flaw. If a condition is significant enough to be called a safety hazard, it is relevant to value, and the appraiser cannot make analysis of a value-relevant condition contingent on the client asking for it. A client's silence is not a scope limitation, and omitting the value effect would leave the report misleading.

Option C: Assume the flue is operable unless a certified chimney sweep report is provided.

Assuming the flue is operable would be an assumption contrary to what the appraiser observed, since efflorescence, spalling, and the absence of a liner are already in evidence. Waiting for a chimney sweep report shifts the appraiser's own duty to identify relevant characteristics onto a third party. If verification were genuinely needed, the proper device would be a disclosed extraordinary assumption or an expanded scope of work, not silence.

Option D: Classify the entire structure as 'Substandard' and assign a 'Poor' overall condition rating.

One deficient component does not justify a blanket rating for the entire improvement. The plaster, hardwood flooring, and structure remain sound, and a condition rating must reflect what was actually observed. Overstating a defect misleads in the opposite direction and distorts comparison with sales rated on the same scale.
