Refusing to allow reasonable modifications to a person with a disability's residence is what?

Refusing to allow reasonable modifications to a person with a disability's residence is against the law due to the protections established by the Fair Housing Act (FHA) and similar state laws. These laws mandate that housing providers must make reasonable accommodations for individuals with disabilities to ensure their equal opportunity to use and enjoy a dwelling. Modifications might include structural changes that improve accessibility, such as installing ramps or grab bars. Failure to permit these modifications can be deemed discriminatory, as it adversely affects the ability of a person with a disability to live independently and fully utilize their home.

The legal framework serves to safeguard individuals with disabilities from discrimination in housing, thereby promoting equity and inclusion within the residential housing market. This protection is not limited to public housing; it applies to all types of housing accommodations. Consequently, the refusal to allow these modifications is not just an ethical issue but also a violation of the law, making the answer correct.
