Not enough signal yet to read this bill's trajectory — we surface a likelihood only once there's real movement (stage, sponsorship, committee, or votes) to point to.

Prognosis reads this bill's own signals — stage, sponsorship breadth, committee status, recorded votes and cross-state momentum. Odds come from a model trained on which bills have become law.

In plain language

The bill allows more accessory dwelling units in residential zones and limits local building requirements.

This bill amends the Illinois Municipal Code to require municipalities to allow accessory dwelling units in residential areas, with specific limits on units based on lot size. It also imposes deadlines for municipal plan reviews and inspections, and restricts parking requirements for certain residential buildings beginning in 2027.

What this means for you
  • Workers: By allowing more housing units, this bill may help workers find affordable housing options.
  • Families: This bill could make it easier for families to create additional housing options on their properties.
  • Small Business: Small businesses may benefit from reduced parking requirements for mixed-use developments.

Summary

Amends the Illinois Municipal Code. Provides that, 8 months after the effective date of the amendatory Act, a municipality shall, on any lot located in a residential zoning district that permits single-family dwellings, allow (1) on an area of not more than 2,500 square feet, at least one detached single-family dwelling unit; (2) on any lot with an area of more than 2,500 square feet and not more than 5,000 square feet, up to 4 dwelling units; (3) on any lot with an area of more than 5,000 square feet and not more than 7,500 square feet, up to 6 dwelling units; and (4) on any lot with an area of more than 7,500 square feet, up to 8 dwelling units, including cottage clusters. Provides that each municipality shall permit accessory dwelling units in all zoning districts that permit single-family dwellings without additional requirements for lot size, setbacks, aesthetic requirements, design review requirements, frontage, space limitations, or other controls beyond those required for single-family dwelling units without an accessory dwelling unit. Provides that, if a municipality fails to complete its plan review within the deadlines established under the provisions, then the applicant may retain a qualified third-party plan reviewer. Provides that, if a municipality fails to conduct a required inspection within 2 business days, then the applicant may retain a qualified third-party inspector. Provides that municipalities authorized to levy impact fees must calculate fees using the statewide formula structure issued by the Department of Commerce and Economic Opportunity.
