How much Section 8 can pay by bedroom size in Illinois

Your voucher pays the lower of the gross rent and your agency’s payment standard, minus your total tenant payment; the standard is the one for the smaller of your voucher size and the unit’s bedrooms. Standards are normally set at 90% to 110% of HUD’s published fair market rent for the area. Illinois’s FY2027 two-bedroom fair market rent runs from $930 in Carroll County, IL and 40 other areas to $2,341 in Kendall County, IL; three bedrooms, $1,108 in Cumberland County, IL and 5 other areas to $3,042 in Kendall County, IL.
