The ARO Matrix is designed to help decode the rules for Affordable Requirements Ordinance (ARO) in Chicago. We know that the rules can be confusing, especially because there is a different ruleset for each of the five ARO areas, and we want to help make the process of calculating how much affordable housing is required as straightforward as possible.

Access the ARO Matrix directly (this is for Cityscape Real Estate Pro members only), or after looking up an address in Chicago and opening its Zoning Assessment. The 45-second video below walks through how to get there.
