City Council finally passes a permanent ADU law

The ADU pilot program the City Council passed in December 2020 and took effect on May 1, 2021, will finally convert to a permanent law on April 1, 2026 – just shy of five years old. The new policy will increase the permanent eligibility area by a little more than double what the pilot areas allowed (a 135 percent expansion to be more precise). Further expansions are optional and up to each alderperson to decide when and where to “opt in” additional parts of their wards. Additionally, the construction of coach houses will have to comply with unusual labor requirements tacked on by an alderperson who called ADUs “an attack on the working class”.

I was shocked when the ADU ordinance (read it here) passed unanimously, 46-0. The ordinance number is SO2024-0008918, and when you open the legislation details page look for the filename called “SO2024-0008918 ADU 9.23.25 (LRB 10a) (2) (1).pdf”

How do I feel? I’m relieved this seven-year-period of ADU advocacy is over, and I’m disappointed in the outcome. More advocacy will be needed to ensure that most alders maximize the eligibility areas in their wards.

Highlights of the new ADU ordinance

  • the ADU eligibility area increases from 12 percent of the city to 29 percent of the city, with options to increase further
  • the arbitrary cap of 700 s.f. of floor area allowed in each coach house has been removed (there is still a site-specific cap)
  • existing off-street parking can be removed in order to build a coach house on the ground level
  • B (business) and C (also business) zoning districts are now part of the eligibility area
  • ground floor space in mixed-use buildings in B and C zoning districts can be converted to ADUs without having to get a “special use”

I wrote an ADU FAQ for Abundant Housing Illinois.

Chicago Fire share the stadium plan they plan to share with the Plan Commission

Updated September 10 to add this link to the traffic and transportation study, and the town hall video hosted by 3rd Ward Alderperson Pat Dowell.

The Chicago Fire owner, Joe Mansueto, plans to build a soccer stadium on “The 78”, a vacant property in the South Loop. The 78 is a planned development that was approved about six years ago to have office towers and about 10,000 homes in multiple buildings. Since the stadium will significantly alter the approved plan, Related Midwest, the owner of The 78, needs to present the revision to Chicago Plan Commission and gain their approval before also gaining approval from the City Council’s zoning committee and City Council.

Rendering of the stadium, looking north-northeast. Other renderings from the set show the area between the stadium and the riverwalk eventually being redeveloped into buildings and differently-designed outdoor spaces.

Here’s what’s changed

We can see what Mansueto and RM are proposing because they submitted their zoning change application to revise the PD back in July, which was subsequently posted in the City Clerk’s online legislation database. (A zoning change application and a Planned Development amendment are amendments to city law; refer to the approved plan in this PD 1434 document.)

  • The soccer stadium would be located approximately between 13th and 14th Streets. The rights of way for these two streets would be delineated and “dedicated” to the public.
  • Metra tracks would remain where they are. At the north edge of the site they enter the site about 185′ west of Clark Street, and then gradually shift to the east to hug Clark Street. The original plan would realign the tracks so that new streets could intersect Clark Street.
  • For the planners, the PD subareas’ boundaries are reconfigured.
  • Crescent Park is out of the plan. This central park would follow the historical Chicago River alignment, before it was straightened from Polk Street to 18th Street in 1926.
  • The riverwalk would be narrowed to 40′ from the currently approved plan for a 75′ wide riverwalk and 25′ “riverfront amenity zone” adjacent to buildings. (City law requires riverwalks to be a minimum of 30′ wide.)
Proposed open space plan

The stadium would have these pedestrian and bicycle access points:

  1. Wells Street, south from Polk Street
  2. Wentworth Avenue, north from 18th Street
  3. A newly built LaSalle Street, south from the elevated Roosevelt Road. This is also where transit riders from the Roosevelt ‘L’ station or any of the buses that use Roosevelt or Clark would access the site.

There would not be access from Clark Street and points east; some of the Dearborn Park and Burnham Station residents may prefer this, given how some of them reacted when a new CTA Red Line station was proposed at the existing substation on the east side of Clark Street at 15th Street. RM eventually moved the proposal to be within The 78.

The proposed site plan also shows a publicly owned parking structure in phase one, below the Roosevelt Road elevation.

What’s next

Expect another 3rd Ward town hall, in September before the next Plan Commission meeting on September 18. The Plan Commission agenda hasn’t been set so it’s not confirmed that the development team will present on September 18.

The plan can also change again, between now and the Plan Commission meeting. What’s presented at Plan Commission will be what is presented to City Council.

Greenline Homes is building brand new houses with junior ADUs

There’s an upcoming tour for a house like the one described in this post. RSVP for the tour on Tuesday, September 23, 2025.

Greenline Homes builds all-electric 1, 2, and 3 unit houses in Chicago’s South Side, and this year they’ve started building single-family houses with a “junior accessory dwelling unit” on the first floor. An accessory dwelling unit, or ADU, can mean a few things, but generally it means a smaller home within a house that has one or more dwelling units. In Chicago, this is most commonly done by adding an apartment in a basement space of a single-family house or a two-flat, and on the ground floor of an older courtyard building during a renovation that moves shared laundry from the ground floor to in-unit.

Over in Woodlawn, however, Greenline Homes has built what appears as a single-family house but has an apartment with one bedroom and one bathroom in the front half of the first floor. It occupies about one quarter of the houses’s overall floor area. In the rear half of the first floor is the primary unit’s kitchen, living and dining room, and a half bathroom. Upstairs, the space belongs all to the primary unit and has three bedrooms and two bathrooms.

Many Greenline Homes have previously been built as two-flats with a lower level full-floor apartment and an upper level duplexed apartment for the owner. The intention is that buyers have an immediate rental income opportunity, or a place for multigenerational living. Think having an adult child living nearby (on-site!) as they transition from college graduation to full time job or having their first child.

Floor plan for the house at 6537 S Rhodes Ave (view the sale listing on Redfin).

The house is for sale, and there are several others like it, so if you’d like a tour contact Wayne Beals. Here are similar ones under construction that will deliver this year:

Further reading: junior ADUs can also be lockoff units, where the smaller unit is connected to the primary unit via stairs or a locked door, but maintains its only exit to the outside.

AARP Illinois talks to Brian and Steven about legalizing ADUs citywide and statewide

Adam Ballard, the Associate State Director for AARP Illinois, the local chapter for AARP, interviewed Brian P. and I about accessory dwelling units. We discussed:

The conversation is 28 minutes long; if you haven’t dived into ADUs yet, this is a great video to help get you up to speed!

Bonus content: AARP is the largest organizational supporter of allowing accessory dwelling units in all communities because of how they expand the options for people to “age in place” (continue living in the same neighborhood when their housing needs change), earn additional income, or rent their big house to their adult children’s families.

If parking relief is granted to just about every development, why require parking in the first place?

The Chicago zoning code requires nearly every development, new or renovated, to provide on-site car parking. The code also provides relief from that requirement, most often in the form of cutting the requirement in half if the development is in a “transit served location”. Further relief – getting closer to zero parking spaces required – can be requested via administrative adjustment to the Chicago Zoning Administrator. (Learn about other methods of relief from Chicago’s parking mandates.)

Sometimes, however, that administrative adjustment must be converted to an application for variation that’s heard by the Zoning Board of Appeals (ZBA).

Pete Snyder and I tabulated all of the requests for parking relief – by way of a variation application – heard by the ZBA from January 2022 through January 2025.

Here’s what we found in that 37-month period:

  • There were 73 applications for parking relief (an average of two per ZBA meeting).
  • A little more than half of the applications (39) explicitly mentioned the development being in a transit-served location.
  • Those 73 applications requested relief from having to provide 661 car parking spaces.
  • At $10,000 per surface parking space that reflects a savings of about $6.6 million in construction costs.
  • Assuming all spaces would be on the ground, this is the equivalent of 3.5 acres of land which does not need to be acquired or if already acquired can be used for other purposes. Bell Park in Dunning is approximately 3.5 acres.
  • Each applicant pays $500 for the 72 variations and one applicant paid a $1,000 application fee for their special use.
  • Most applicants hired and paid an attorney to handle their application. Lawyer fees vary and are not made known to the public, but for variations are usually multiple thousands of dollars. Lawyers typically charge more for special use applications.

Understanding how much relief from costly parking mandates is incomplete if we only study variations. The default method, at least for locations within transit-served areas, is to ask for an administrative adjustment, which has a lower bar of obtaining approval – but we don’t have data about the number of these. Another way to get parking relief is to apply for a rezoning and bundle the relief request within that application; data on that is forthcoming.
