Allowing ADUs across Chicago: it’s never been more real

tl;dr: sign the petition so I can send the zoning committee the biggest marker of citywide support for citywide ADUs

Mayor Johnson indicated earlier this week that he is interested in legalizing ADUs citywide next week. Fran Spielman reported in the Chicago Sun-Times that he remains steadfast in ensuring that the option is available in all residential parts of the city. To that effect, he plans to submit a substitute ordinance at the next zoning committee meeting on Tuesday, July 15. 

ADUs were re-legalized in Chicago starting on May 1, 2021, in a pilot program available to property owners in five areas of the city. The pilot program turned four years old two months ago.

An ordinance introduced by Alderperson Lawson (44th Ward) over two years ago would dissolve the pilot areas and allow ADUs across the city and make other program fixes. However, the proposed ordinance requires that property owners in certain zoning districts obtain permission from the Zoning Board of Appeals before being able to apply for an ADU building permit.

While Lawson has argued that the votes have existed to pass his version, the mayor’s position is that that difference in treatment based on a property’s zoning district, which alderpersons can change, could continue the problem that the U.S. Department of Housing and Urban Development (HUD) found in October 2023.

After nearly eight years of ADU advocacy – participating in a task force during a previous mayor’s administration, presenting on panels, sharing ADU data with journalists and the public, and garnering support for a geographic expansion of ADUs in the city and Illinois – my primary interest is honing in to ensure that an ordinance legalizing ADUs across the whole of Chicago passes.

I’d like for every reader to sign this petition, created by Abundant Housing Illinois, to show the zoning committee and City Council that there is widespread support for ADUs.

Contacting your alderperson directly on Monday would be a bonus.

Greenline Homes is building brand new houses with junior ADUs

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.

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.

Chicago home builder: Parking mandates limit the number of dwelling units we can build

Chloe G, a co-lead of Strong Towns Chicago, asked this question at the 2-to-4 flats panel that I moderated earlier this month:

“How do parking mandates affect your businesses?”

“It really just limits the amount of units we can do”, Nick Serra answered.

Learn about reform efforts in Chicago to drop costly parking mandates that raise the cost of housing.

Nick, a small local homebuilder, starts to describe how the city’s parking mandates limit how much housing he can build. Watch the full panel video.

Panel: Bringing back 2-to-4 flats

Earlier in March I moderated a panel called “Bringing Back 2-to-4 Flats” at the Metropolitan Planning Council office, interviewing three panelists who are developers and designers for these venerable Chicago housing typology.

Two, three, and four-flats are super common in Chicago, representing about one fifth of the city’s dwelling units. These properties are the most likely to have lower rents and family-sized units, according to the Institute of Housing Studies. But Chicago’s zoning laws severely restrict where they can be built. Changing the zoning laws to allow 2- to 4-flats by right makes it easier to increase the city’s housing supply and grow the economy.

Watch the full panel and Q&A in the video below.

Meet the panelists

  • Neelam Dwivedi is a real estate agent and small local homebuilder. She co-founded Nath Construction in 2018. She has developed numerous 3 and 4 flats, particularly in the Near West Side and East Garfield Park.
  • Nick Serra is a small local homebuilder who founded Grace Street Renovation Lab in 2023 and has completed 15 rehab projects. He was previously a practicing attorney and disliked it so much he pivoted to real estate. 
  • Katherine Darnstadt founded Latent Design, an architecture and urbanism practice in 2010. I met Katherine in 2015 and I think the main thing I remember about her practice is the breadth of it. She’s said that the firm has worked on projects “at the bench, building, and block scale”.

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.
