Named ordinances, statutes, and reforms specific to Chicago — each linked to an official source you can verify directly.

  1. Connected Communities Ordinance(2022)

    Passed by the Chicago City Council in July 2022, the Connected Communities Ordinance is Chicago's most comprehensive transit-oriented development reform. It reduces parking minimums and increases as-of-right FAR/density bonuses on properties within 1,320 ft of a CTA/Metra station entrance (or 2,640 ft along designated Pedestrian Streets), and adds equity protections such as anti-displacement requirements in higher-cost transit areas. It implements the 2021 ETOD Policy Plan.

  2. Equitable Transit-Oriented Development (ETOD) Policy Plan(2021)

    Adopted unanimously by the Chicago Plan Commission in June 2021 after an 18-month outreach process. The plan establishes equity as the guiding framework for TOD, sets goals around investment in disinvested communities, prevents displacement in rising-cost neighborhoods, and promotes affordable housing near transit. Predecessors: 2013 TOD Ordinance, expanded 2015 and 2019.

  3. Affordable Requirements Ordinance (2021 ARO)(2021)

    Residential developments receiving City Council approval for an entitlement, city land sale, or financial assistance after October 1, 2021 are subject to Chapter 2-44-085 of the Municipal Code (the 2021 ARO). Affordability period is 30 years; affordable rental units generally target 60% AMI (up to 80-100% in some cases). Replaces the 2015 ARO at Chapter 2-44-080.

    Chicago's ADU Ordinance took effect December 1, 2020 in five designated pilot areas. Permitted ADU types include coach houses (rear-yard detached units, historically legal in Chicago before being banned in 1957), conversion units (basement/cellar/attic conversions in 2-7 unit buildings), and added attic/cellar units.

Chicago Zoning Overview

Chicago is a city in Illinois that manages land use and development through its local zoning ordinance. The city's zoning code divides the municipality into districts that regulate the types of uses permitted, building heights, lot sizes, setbacks, and density. Residents and developers should consult the city's planning department and municipal code for the most current zoning regulations and requirements.

The city's zoning ordinance typically includes residential, commercial, industrial, and mixed-use districts, each with specific development standards. Residential districts range from low-density single-family zones to higher-density multi-family zones. Commercial districts accommodate retail, office, and service uses, while industrial districts are designated for manufacturing and warehousing operations.

Development Process

Development in Chicago generally requires obtaining the appropriate permits from the city's planning and building departments. The process typically involves:

  1. Zoning Verification — Confirm that your proposed use is permitted in the applicable zoning district
  2. Site Plan Review — For commercial and multi-family projects, submit a site plan for review
  3. Building Permit — Apply for a building permit with construction documents
  4. Inspections — Schedule required inspections during construction
  5. Certificate of Occupancy — Obtain final approval before occupying the structure

For projects that do not conform to existing zoning, property owners may need to seek a variance, special exception, or rezoning through the local board of zoning appeals or planning commission.

Key Considerations

Before starting any development project in Chicago, property owners should:

  • Verify the zoning classification of their property
  • Review setback, height, and lot coverage requirements
  • Check for any overlay districts or special regulations
  • Determine if the property is in a flood zone using FEMA's flood map service
  • Confirm whether HOA covenants or deed restrictions apply
  • Contact the planning department for pre-application guidance
