AI Summary
This bill mandates that municipalities in Illinois authorized to collect impact fees, which are fees charged to developers to offset the costs of new development on public services and infrastructure, must use a standardized statewide formula structure developed by the Department of Commerce and Economic Opportunity (DCEO) to calculate these fees. The DCEO will annually update and make public essential information for these calculations, including multipliers estimating service demand by housing type and statewide cost estimates for schools, parks, transportation, and public safety, along with allowable adjustment factors and a model ordinance that municipalities must adopt. While municipalities can choose to charge less than the maximum fee calculated by the formula, they cannot exceed it, and they must publish a schedule detailing the formula-generated maximum fee, the state-issued multipliers and assumptions used, any municipal adjustment factors, and any reductions adopted. Furthermore, municipalities must annually report to the DCEO on fees collected, expenditures, fund balances, housing units approved, and any use of adjustment factors, and the bill specifies mandatory exemptions for affordable housing, supportive housing, transitional housing, and accessory dwelling units, while allowing for additional reductions for certain types of development. This legislation, which limits home rule powers and applies to residential development 30 months after its effective date, aims to create more predictable, transparent, and fair impact fee calculations across the state.
