Why Chicago should have a rental registry

This is a publicly accessible scratchpad of what I’m thinking. As I already said, Chicago should have a rental registry, a database of dwelling units that are rented to tenants, for at least two reasons:

  1. The city can know things about the rental units, including how much they cost, where they are, and if any are vacant and could be occupied if only people knew they were available and how to get in touch with the owner. 
  2. The city can know who the owners are and contact them to issue citations or advise them, or fill out for them, emergency rental assistance during pandemics and other times of necessity.
Who owns and rents each of these buildings, and are they providing a quality apartment to their tents?

Rationale for a rental registry

  • It could improve the quality of housing by forcing renovations when tenants are not making complaints due to the potential for retaliation or eviction.
  • Chicago’s complaint-based inspection system misses a lot of life-threatening situations (Illinois Answers Project, article 1, 2023; and Illinois Answers Project, article 2, 2023)
  • Tenants should be able to know who owns the property they rent. Under the current data regime in Illinois, it’s unreasonable to expect a tenant to know how to look up this information. Of course, someone could use my Chicago Cityscape platform to look up property ownership and transfers.
  • Chicago could put bad landlords out of business (Illinois Answers Project, 2021).

What do you think forms the basis for Chicago to have a rental registry?

How many more homes does Chicagoland need and is it 120,383?

Up For Growth, a national “moar housing” research group, publishes an annual report about underproduction of housing in 193 regions, including Chicagoland. In their 2023 report they found that there’s an underproduction of 120,383 homes in the Chicago-Naperville-Elgin, IL-IN-WI metropolitan statistical area.

This graphic shows how U4G derived that figure of missing homes.

Housing underproduction as a narrative formula:

((existing households + missing households) * 1.05 [1]) - (total housing units + second/vacation homes + uninhabitable units) = underproduction

[1] means a 5% target vacancy rate

The novel metric here is “missing households”, which are households that haven’t formed due to a lack of housing. The report’s definition:

Missing Households. Households that may not have formed due to lack of availability and affordability, e.g. households with children over 18 years of age still living with their parents or individuals or couples living together as roommates at levels exceeding historical norms.

In the Chicago region, 120,383 homes represents 3.1 percent of the housing stock in 2021, meaning we need to grow the number of homes in Chicagoland by 3.1 percent to accommodate these emerging families, graduating students, roommates, and doubled-up tenants. The necessary expansion of housing is greater than 3.1 percent, however, to accommodate migration and homes no longer in the market due to various forms of vacancy.

We also need more housing to help prices flatten or go down, and reduce the number of households that are cost-burdened. Among the top 10 cities with the most housing underproduction, Chicago has the lowest share of households which are cost-burdened, at 46.0 percent.

It’s time to submit a “witness slip” in favor of the Illinois ADU bill

The ADU legalization bill that I discussed last month in a post about State Rep. Kam Buckner’s three statewide land use reforms has been assigned a committee and hearing date and time. This means individuals can submit witness slips in favor of allowing “accessory dwelling units” up and down the state.

The Cities & Villages Committee will meet on Tuesday, March 12, at 4 PM, which is also the deadline to submit a witness slip (instructions below).

How to submit a witness slip for ADUs

The deadline is 3/12/24 at 4 PM.

  1. First, open up the ILGA’s Witness Slip webpage for HB4213.
  2. In the witness slip form, fill out your name, address, and city.
  3. In the “Firm/Business Or Agency” field, enter “self” or the name of an organization you’re representing.
  4. In the “Title” field, enter “self” or your title in the organization you’re representing.
  5. Enter your email and phone number.
  6. In the “Representation” field, enter “self” or the name of the organization you’re representing.
  7. In the “Position” section select the “Proponent” radio button.
  8. In the “Testimony” section tick the “Record of Appearance Only” checkbox.
  9. Tick the “I agree” checkbox
  10. Finally, select the “Create Slip” button and you’re done!

Submitting a witness slip is an easy thing to do from home. If you’d like to elevate your advocacy for housing options in Illinois, email or call your state legislator, and join Urban Environmentalists of Illinois to learn about getting even more involved.

Letter to the editor: Legalize housing abundance across Illinois

My letter to the editor of the Chicago Sun-Times was published on February 26, 2024.

State Rep. Kam Buckner of Chicago has introduced another land use bill that Illinoisans should support. The bill provides that municipalities with a population of 100,000 or more should allow property owners to have more than one home on a lot. This forward-thinking legislation represents a significant step toward addressing the pressing housing challenges facing our communities and would foster more inclusive and sustainable urban development.

The shortage of affordable housing in Illinois for middle-class families, particularly in the Chicago area, has reached a critical point. New housing in places with access to jobs, opportunities and amenities has not kept up with demand.

Buckner’s bill acknowledges the need for innovative solutions to tackle this issue head-on. By lifting the ban on multifamily housing options in residential zones, the legislation promotes diversity in housing types, catering to the needs of our population.

I believe cities that don’t allow enough housing should not be able to push people to remote areas that have cheaper housing and less access to the things that make our cities great. This sprawl has devastating effects on our agricultural land and natural open space, ultimately increasing the tax burden on municipalities by extending and maintaining utilities to far-flung, lower-density areas.

More often than not, residents of sprawling development have higher transportation costs, according to research by the Center for Neighborhood Technology.

In Houston, America’s fourth-largest city with a lot of sprawling development and limited alternatives to driving, 34.4% of households pay 45% or more of their income just for housing and transportation. In Chicago, on the other hand, only 27.5% of households pay 45% or more of their income on housing and transportation.

Multifamily housing— which could be as little as two homes on a lot — not only provides more affordable options but also promotes a more efficient use of space and resources. By fostering mixed-use development, it’s easier to create and sustain neighborhoods with vibrant retail in walking distance.

Our legislators should recognize the positive impact that allowing multifamily housing can have on affordability, community development and overall urban sustainability. It’s time to embrace progressive measures that will shape a more equitable and prosperous future in Illinois.

Why courtyard buildings aren’t allowed in Chicago anymore

Chicago Urbanist Twitter was abuzz this month when renderings of a proposed construction courtyard building were published (they’re shown below), given that the historical building typology hadn’t been built in Chicago in decades. Some wondered if this revered local design was making a return.

The post is probably better titled “how it is that courtyard buildings aren’t built in Chicago anymore” as I don’t know why the codes changed in such a way to, effectively, do away with the housing typology. And it’s the second time I’ve evaluated the feasibility of building a specific housing typology; see my post about cottage clusters.

I don’t think there will be a resurgence or resurrected trend in building courtyard buildings in Chicago, because of how the city’s building and zoning codes inhibit them. At the end I discuss how Chicago might get courtyard buildings to return.

Chicago has several variations of courtyard buildings

Common variations of Chicago courtyard buildings include:

  1. Large inset front courtyard (U-shaped) buildings
  2. Buildings with rear courts, often with exterior unenclosed porches or a small rear yard and possibly a garage (I speculate providing a space for one or two cars in a 20-unit building was meant for the building owner)
  3. Side court buildings
  4. S-shape and multi-court (which are kind of modular)

People like Chicago courtyard buildings

To describe the Chicago courtyard building, I compiled reasons why people like courtyard buildings, especially the type with the front courtyard based on conversations I observed on Twitter and by asking members of Urban Environmentalists of Illinois.

  • They look nice, with all of the landscaping visible from the sidewalk. Landscaping isn’t relegated to the roof and can be seen by the public.
  • Everyone’s unit has a designated nice view, as every unit faces the inner court. Compare this to a double-loaded corridor where about half the units will face the street and the other half may face the alley.
  • The unit layouts are some of the best; the apartments have lots of natural light and all rooms have windows. The units are often “dual aspect” and with windows on two walls the unit can have cross ventilation. This may be a subjective, though, as the use of constant mechanical air flow with filtering and exhausting may provide some with greater comfort. Additionally, the need for cross breeze is less necessary given air conditioning and low-cost energy.
  • Courtyard buildings enable many different unit types within one development (studios and 1-3 bedrooms), which means there can be a decent mix of types of people (families and singles and couples.) This is unlike a building using a double-loaded corridor floor plan, which often place multi-bedroom apartments at the corners.
  • Most units are pretty quiet since some of the unit’s layout is not directly against street, not too noisy.

Learn more about floor plan design significance by listening to this Odd Lots podcast interview with Stephen Smith and Bobby Fijan.

I also feel that a courtyard by building’s layout is similar to a point access block’s (i.e. two or three units per floor per stairwell). Even though the courtyard buildings can be large, their multiple cores help them appear “small-scale and homey compared to having long hallways. You actually know people in your stairwell, not a bunch of strangers” (Jesse O.). (This also means they utilize space more effectively than double-loaded corridor buildings, which has impacts on cost.)

Mike Eliason is a major proponent and promoter of point access blocks because they offer a superior layout; his book, to be published this year, will argue that, but you can get a preview of his reasonings by reading through his Twitter (like this tweet) or reading the point access block policy brief that his architecture firm wrote for the City of Seattle.

If you’d like to learn more about the courtyard building’s history, Moss Design, a local architecture firm, explores the advantages and history of courtyard buildings in Chicago (the post is from 2014).

Zoning code conflicts

Courtyard buildings are difficult or impossible to build in Chicago for many of the reasons that I described in a previous post about how to amend the zoning code to allow “cottage courts” in Chicago. They are repeated here:

  1. Rear setbacks would need to be reducible, preferably without the need for a variation from the Zoning Board of Appeals. Because the houses are oriented to face a common green space at the interior of the lot (not at the front or rear of the lot), the rear of the house may be close to the rear property line, violating the rear setback standard of ~30 feet. 
  2. Side setbacks would need to be combinable or eliminated as a requirement for courtyard buildings because the unbuilt space on the property that is normally required for a rear yard is concentrated in the interior court pushing the building to the edges of the property.
  3. Parking requirements would need to be more flexible, both in quantity and in design, otherwise the parking areas would occupy a third to half of the property, minimizing the space that can be used for the interior court. To maximize the shared green space, parking requirements should be reducible for this housing type. The Chicago TOD ordinance that reduces parking requirements may be relevant here, as it now applies in RM-5, and higher, residential zoning districts (notably rare).
  4. Minimum lot area per unit standards can likely be met cost-effectively in the less common RM-5 and higher zoning districts. The most common residential zoning districts in Chicago are RS-3 and RT-4. The RS-3 zoning districts do not allow more than two units on a lot; in RT-4 zoning districts the developer would have to assemble so many lots to be able to get the unit count necessary to make such a building’s construction cost-effective yet the land acquisition might be so costly as to make the project infeasible.

Walk around Rogers Park, Lakeview, and Hyde Park – where it seems the most courtyard buildings were built – and you’ll see that most of them don’t have any car parking. And the ones that do certainly don’t have as many to meet current car parking requirements.

Building code conflicts

Note that “IANAA” (I am not an architect) and my expertise on building codes is always quite limited.

Exits and stairs. The Chicago building code generally requires a minimum of two stairs for buildings of an occupancy classification of R-2 (multifamily with four or more units, not including shelters); see section 1006.3.2 in the Chicago building code for info about two-exit standards.

The two exits must also be within a minimum and maximum distance apart from each other; this standard ends up requiring a corridor between the two stairs so that each unit can access either stair. This corridor eliminates rentable area and decreases the floor plan’s efficiency (a metric for architects and developers that affects the pro forma).

In the new construction courtyard building’s renderings at the top of the post, there are three interior stairs! See also the Standard 8-3 comment below.

Section 1006.3.3 in the Chicago building code outlines the single exit (single stair) conditions. Without going further into alternatives and exceptions, a three-floor three-flat can be a single stair building as long as the third floor doesn’t exceed 1,600 s.f. of floor area and the house has a sprinkler system ($$). You read that right…Chicago allows single stair for buildings with 1-3 units and 1-3 floors.

Existing courtyard buildings in Chicago that don’t have a second interior exit stair will then have an exterior exit stair, often connected to porches; this example has a minimal shared porch attached to the exterior exit stair at a courtyard building.

There are limitations on the use of exterior stairs for exiting requirements and I’m unable to articulate their impact on size or orientation. They cannot be used for exiting on floors that are 45 feet above grade, and cannot provide “more than 50 percent of the number and minimum width or required capacity of means of egress components” (1027.2.1). There are also standards on the exterior stair materials.

Long corridor. The minimum corridor length and the sometimes-extra stairs require a bigger building footprint (increasing construction cost compared to a building without corridors, like the point access block), which is already constrained by parking mandates and inexplicable zoning code setback requirements. See section 1007.1.1 in the Chicago building to learn about how far apart exits need to be.

It’s not actually the multiple stairs that are the space hog…it’s the corridor that’s required to connect the multiple stairs.

Setbacks. Fire separation distance is different than a zoning setback. The building code allows buildings to abut (touch) adjacent buildings but the fire protection standards on that side of the building are increased. No windows could be built on a wall that has zero setback, so natural light and vent requirements for bedrooms would have to be provided through light courts and placing bedrooms at the front or rear of the building.

A quick note about elevators: it’s my understanding that an elevator is not required if the required accessible Type A units (20 percent) are at grade and no floors above the ground floor contain building amenities (1104.4).

Do you know of some other regulatory standards that affect the development feasibility of courtyard buildings and point access blocks in the United States?

Return of the courtyard building in Chicago?

As I said at the beginning, I don’t think the one proposed new construction courtyard building will lead the resumption of the courtyard building in Chicago. There are the conflicts in the codes that I think would need to be significantly modified to facilitate new courtyard building construction.

I also believe that there are other factors: who develops, who designs, who lends, and who would live there that matter. These may be more influential in whether a new courtyard building gets built in 2024 than the zoning and building code conflicts; in other words, what if the city tweaks those codes and no new courtyard buildings get built?

I’m thinking of the “Standard 6-3” building I promoted, a typical design in Chicago that was re-legalized in some areas of the city when the Connected Communities Ordinance was passed in 2022. That zoning code amendment allows for a six-flat (back to back apartments on three floors) to be built on a standard size lot with minimal or no car parking. To my knowledge, though, none have been built.

Then there’s the circumstance that the double loaded corridor makes a lot of financial sense for developers and construction companies; the identical unit layouts are easy to design and build and the density of units is quite high. Plus the floor plate efficiency is significantly higher in a DLC compared to a single-loaded corridor (which Chicago has some of, in the form of “California style” apartments). DLC buildings often have a much greater proportion of studios and one-bedroom units, which, on a per-square-foot basis, collect more rent than larger units.

To comment on those factors of developer, designer, lender, and tenant, I would defer to asking those people, which is beyond the scope of this blog post. Conveniently, a developer of smaller-scale multifamily buildings, Coby Lefko, wrote a guest article on Noah Smith’s blog that I think addresses some of the friction to develop something like a courtyard building.

Coby writes, “Even while recognizing the need for comprehensive solutions, too many urbanists have ignored the importance of finance [emphasis added] in charting a different course for the future.” The thrust of the article is that cities need small developers but it’s hard to be a small developer.

I think many urbanists, myself included, opine on development in ways that fail to reflect lacking the knowledge of experience of having actually built something. I’m trying to gain more knowledge about it; recently, I nominally learned how to read and write a pro forma, a special spreadsheet that developers use to gauge the cost and benefit of a specific proposal.

As more of us consider land use reforms to allow for housing abundance in Illinois, let’s also discuss “supporting new courtyard buildings” – they provide desirable unit layouts, small and family-sized apartments, cozier neighbor arrangements, and Chicagoans just really like them!
