Although appraisers are not required by USPAP to adhere to a specific standard of square footage measurement, appraisers are required by Standards Rule 1-1(b) to not commit a substantial error of omission or commission that significantly affects an appraisal. This rule requires the appraiser to gather factual information in a manner that is sufficiently diligent. Standards Rule 1-1(c) requires appraisers to not render appraisal services in a careless or negligent manner. Appraisers must use due diligence and due care in performing appraisal services, including gathering factual data such as square footage.
Therefore, depending on your specific situation, you may be required to comply with ANSI, or you may just be choosing to comply with ANSI. Thus, if you have choosen to comply with ANSI, but only with some of its parts, then it may be appropriate in your scope of work disclosure (in order to avoid being misleading) to state which parts of ANSI you did and did not comply with. Additionally, rounding (or not rounding) is a technique and therefore, the technique may or may not be appropriate for your specific assignment.
In other words, the answer to your question is that it depends on your specific assignment.
