It is illegal to discriminate against someone based on his or her age. Age is a protected category under the Delaware Fair Housing Act for individuals who are any age 18 years or older. If you are denied an opportunity to rent, buy, finance or insure or a home or apartment—or given false information about housing—because of your age, you are a victim of illegal housing discrimination. It is also illegal for landlords or other housing providers to treat current residents or tenants, or their guests, unfavorably because of their age.
Minors (children under the age of 18) are not protected (minors are protected under familial status) and the protections do not extend to residency in state or federally-aided housing for the elderly, or to housing intended for persons 55 years of age and over, or to housing for individuals age 62 or over.
If you believe you were discriminated against because of your age, file a complaint.
