The Arbor Heights community's zoning ordinance that requires group homes designated for disabled citizens to be situated outside of city limits violates which act?

The Fair Housing Act is the correct answer because this act specifically prohibits discrimination in housing based on disability, among other factors such as race, color, national origin, sex, and familial status. By requiring that group homes for disabled citizens be located outside of city limits, the Arbor Heights community's zoning ordinance effectively discriminates against individuals with disabilities by limiting their access to housing opportunities.

The Fair Housing Act aims to ensure that people with disabilities have the same rights as individuals without disabilities to live in any community of their choice. This is a critical aspect of promoting equality and preventing segregation based on disability.

While the Americans with Disabilities Act also addresses issues related to individuals with disabilities, it primarily focuses on public accommodations and services rather than housing. The Rehabilitation Act deals with discrimination against individuals with disabilities in federally funded programs but does not specifically address housing rights as comprehensively as the Fair Housing Act does. The Equal Protection Act, while relating to discrimination, does not exist as a standalone federal statute and is often interpreted through Constitutional law, which may not apply directly to housing situations in the same way as the Fair Housing Act.
