Eligibility for a section 8 housing voucher is dependent on gross income. To be eligible, a family must have citizenship status and an annual gross income less than 50 percent the median income of the area in which you live, according to the U.S. Department of Housing and Urban Development.
Even if a family is eligible for the section 8 housing voucher, they are generally put on a waiting list and do not receive the voucher until their family is at the top of the list. The law also states that the 75 percent of the vouchers must be provided to families whose income is below 30 percent of the area's median income so these families have top priority. The U.S. Department of Housing and Urban Development determines your area's median income and your eligibility.
