For Public Housing, tenants have the opportunity to choose which type of rent they want to pay. Each tenant has the choice to pay rent based on their income or a flat rent option. If you choose to pay based on your income, your rent will be calculated at 30% of your monthly adjusted income. If you choose the flat rent option, your rent will be based on the apartment size. For Section 8, your rent will generally be 30% of your adjusted gross income with some exceptions. Your caseworker will explain the rent calculation to you in further detail.
