Zillow's Commitment to Fair Housing
Zillow's Fair Housing Classifier is a significant step towards promoting responsible and unbiased behavior in real estate conversations. The tool is designed to detect and prevent illegal steering, a practice where buyers are influenced based on legally protected characteristics such as race, color, religion, gender, disability, familial status, or national origin.
"Since 2006, Zillow has used AI to bring transparency to home shoppers, powering tools like the Zestimate," said Josh Weisberg, senior vice president of Artificial Intelligence at Zillow. "We've made it our business to increase transparency in real estate — open sourcing this classifier demonstrates that advancements in technology do not need to come at the expense of equity and fairness for consumers."
Addressing Discrimination in Housing
The Fair Housing Classifier acts as a protective measure, identifying questions that could lead to discriminatory responses in real estate experiences, such as search or chatbots. It flags instances of noncompliance, allowing system developers to intervene and ensure fair housing practices are upheld.
Michael Akinwumi, Ph.D., chief responsible AI officer at the National Fair Housing Alliance, emphasized the importance of such tools in today's AI landscape. "Promoting safe, secure, and trustworthy AI practices in housing and lending is becoming increasingly important to protect consumers against algorithmic harms," he said. "Zillow's open-source approach sets an admirable precedent for responsible innovation."
Collaborative and Open-Source Approach
The decision to offer the Fair Housing Classifier as open-source underscores Zillow's commitment to transparency and equity. Organizations and developers can access the code and comprehensive framework on GitHub. Trusted partners can request access to training data and a pretrained model, fostering a collaborative effort to improve the tool.
Zillow encourages other organizations and coalition groups to actively participate, test, and enhance the model, sharing their findings with the public. This collaborative approach aims to continually refine the classifier and address any edge cases that may arise.
The Need for Fair Housing Tools
A recent Zillow survey highlighted the ongoing issue of housing discrimination. The survey found that 57% of respondents reported experiencing some form of housing discrimination, with higher rates among LGBTQ+ populations, Black individuals, and Hispanics and Latinos. Despite nearly 60 years of fair housing laws, discrimination remains a persistent problem.
By making the Fair Housing Classifier available as open-source, Zillow is taking a proactive step to address these issues. The company's ethical AI team has also published AI principles to prioritize equitable outcomes in real estate.
Conclusion
Zillow's release of the Fair Housing Classifier represents a significant advancement in promoting fair housing practices through AI technology. By offering this tool as open-source, Zillow is fostering a collaborative effort to ensure equity and transparency in real estate, ultimately benefiting consumers and the industry as a whole.
