The city’s Affordable Requirements Ordinance reduces the revenue generated by an apartment project, depressing the developer’s return. For a hypothetical 224-unit project built on a lot on the Near North Side that costs $14 million, the return falls below the minimum 6 percent needed for a developer to move forward, according to an analysis by Cushman & Wakefield. But if the cost of the lot drops to $4 million, a developer would move forward.
