The Elizabeth Church building (Building 1) and the Burch building (Building 2) have income and rent guidelines established by The Department of Housing and Urban Development (HUD).
Each year HUD releases income guidelines and determines the market rent. A resident must have GROSS INCOME below the HUD level in order to live in the building. Even if you have chosen an apartment without assistance, if it is in a building with a HUD contract, you must meet those income thresholds.
In the case of the Colton Weinberg building, (Building 3) where there are no subsidies, income is reported to show ability to pay.
