What factor is not considered by HUD when reviewing fair housing complaints?

The correct factor that is not considered by HUD when reviewing fair housing complaints is the number of pets. The Department of Housing and Urban Development (HUD) primarily focuses on protected characteristics under the Fair Housing Act. These characteristics include race, disability status, and gender identity, among others, which are directly related to discrimination issues in housing.

While the number of pets may be relevant in specific situations, such as rental agreements or pet policies, it does not fall under the categories that HUD is mandated to monitor for fair housing complaints. This lack of relevance to discrimination based on race, disability, or gender identity makes it clear why the number of pets is not a consideration in HUD’s legal framework for fair housing.
