If you own an emotional support animal, you are protected from housing discrimination by federal law. The Fair Housing Act and guidelines from the U.S. Department of Housing requires landlords to reasonably accommodate ESA owners. That means that your housing provider has to allow your ESA even if the building strictly bans all pets. ESA laws are clear, landlords can also never charge any pet fee, deposit or application fee for accepting your ESA. ESAs are considered a type of assistance animal under federal guidelines and are thus exempt from building rules that limit pets. For instance, ESAs are not subject to breed, size and weight limitations that may apply to tenant’s pets.
