Most units that we manage are not funded by income-based programs, which means that rent levels are set when you first qualify for the unit. If your income goes up or down, your rent is controlled for limited increases based on your initial income. Each unit is assigned a specific designation based on a tenant’s household income (for example, 30% AMI, 40%, 50%, etc.). Each year, the City of Chicago and the Illinois Housing Development Authority provide unit rent limits based on AMI, which typically take effect in June.
