The proposed advisory is intended to provide guidance on how appraisers can responsibly use evolving technologies—including artificial intelligence (AI), machine learning systems, regression software, and automated valuation models (AVMs)—while continuing to comply with the Uniform Standards of Professional Appraisal Practice (USPAP).
Why This Matters
Technology is increasingly integrated into appraisal practice, offering tools that can assist with research, analysis, and reporting. At the same time, these tools raise important questions related to appraiser responsibility, competency, transparency, data quality, and public trust.
While USPAP’s core principles remain unchanged, the ASB issued this exposure draft to clarify how existing requirements apply when advanced computer technology is used in appraisal and appraisal review assignments.
Key Themes in the Proposed Guidance
The proposed AO-41 emphasizes that technology—no matter how advanced—remains a tool, not a substitute for professional judgment. Among the central points addressed in the draft:
- Appraiser Responsibility
Appraisers remain fully responsible for developing credible assignment results. A tool’s output is not an appraisal conclusion, and reliance on technology does not transfer USPAP accountability away from the appraiser.
- Data Quality and Analysis
The credibility of any analysis depends on the relevance and quality of the underlying data, not the size of the dataset or the sophistication of the software. Appraisers must evaluate comparability, apply appropriate adjustments, and identify errors or weak correlations.
- Competency and Understanding
Appraisers must be competent in the use of any technology they rely upon, including having a basic understanding of statistical concepts used in the analysis. Relying on outputs or terminology that the appraiser does not understand may violate USPAP’s COMPETENCY RULE.
- Transparency and Documentation
When technology is used, appraisal reports and work files should include sufficient information to explain the analysis performed, the data relied upon, and how the appraiser reached their conclusions.
- Public Trust
The proposed guidance reinforces that responsible use of technology must align with USPAP’s overarching goal of promoting public trust in the appraisal profession.
