No. The law doesn’t prevent an “appraiser trainee” from preparing an appraisal report, but it requires a review and signature of a certified real estate appraiser as the supervisory appraiser. Remember that Standard Rule 2-3 USPAP requires the name of each individual providing significant professional assistance be stated in the certification of the report.
Appraiser regulations, rules, and standards don’t require you to report the presence or absence of carbon monoxide detectors in an appraisal report; nor are we aware of any legislation establishing responsibility for such reporting. A client may request you to report the presence or absence of a carbon monoxide detector. It is up to you to accept or refuse the assignment.
