IL SB3187

Requires local governments to permit multifamily and mixed-use developments as by-right uses on land owned or leased by faith-based organizations, eliminating the need for discretionary zoning approvals such as special use permits, variances, or plan commission recommendations.

Prohibits local governments from restricting building height below 60 feet or 5 stories, requiring setbacks greater than 10 feet (front/rear) or 5 feet (sides), or imposing minimum off-street parking requirements beyond ADA compliance.

Removes local authority to limit development through density caps, floor-area ratios, lot coverage restrictions, minimum/maximum unit sizes, or subjective design standards based on "neighborhood character" or "compatibility."

Applies to properties owned by religious corporations, congregations, or affiliated 501(c)(3) nonprofits, including land held by trustees for religious purposes or under leases of 30+ years, with exceptions for sites within one-quarter mile of heavy industrial uses, commercial airports, or military installations.

Mandates ministerial review with 30-day completeness determination and 60-day approval timelines, preserving local authority only over objective health and safety codes such as building, fire, stormwater, and accessibility requirements.
