City implements AI for property valuation with human oversight and appeals process

The Madera County Board of Supervisors held a regular meeting on April 15, 2025, where discussions centered on the implementation of artificial intelligence (AI) in property valuation and the associated appeals process for residents.

The meeting began with a focus on the new AI software designed to calculate property values. Concerns were raised about the reliability of AI-generated assessments. In response, officials assured attendees that there would be human oversight in the process. Appraisers will still have access to traditional methods and will be able to review AI-generated values. If discrepancies arise, particularly those exceeding 10% of market values, the system will flag these for further examination.

The appeals process was also highlighted, with officials confirming that residents can contest AI assessments through the assessment appeals board. This process ensures that human judgment remains integral to property valuation, allowing for a thorough review of AI-generated data.

Further discussions emphasized the efficiency and stability that the new AI system brings to the office. The transition from outdated spreadsheets to a more reliable digital platform was noted as a significant improvement. The AI system not only streamlines data entry but also enhances the accuracy of property comparisons, providing users with detailed information, including likeness scores and images of comparable properties.

Additionally, the meeting addressed the financial implications of the new software. Officials confirmed that the projected net savings from implementing the AI system, after accounting for maintenance costs, would amount to $70,000.

The meeting concluded with expressions of gratitude towards the staff for their efforts in modernizing the property assessment process. The Board emphasized the importance of adapting to new technologies while maintaining accountability and transparency in property valuations.
