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).

What do you like about courtyard buildings?

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!

Chicago City Council could end up voting to ban new dollar stores

Update: This ordinance passed out of licensing committee on Monday, January 22, 2024. Also, the link to the ordinance is not working and I can’t find another way to link to it on the City Clerk’s legislation database. The version that passed out of committee reduces the radius from 2 miles to 1 mile and reduces the threshold for fresh and frozen food to avoid the radius minimum from 40 percent to 10 percent.

Update 2, February 22, 2024: A substitute ordinance was passed by City Council yesterday; the thresholds described in the paragraph above were established but the distance separation clause was amended so that only dollar stores of the same owner are banned within one mile. In other words, and this is dependent on the definition of “controlling person” in the code at section 4-4-005, a Dollar General could not open within one mile of a Dollar General or a Dollar Tree, but a Family Dollar could. A new map is shown at the end.

Ald. O’Shea (19th Ward) has proposed an ordinance with 35 cosponsors that would ban dollar stores within two miles of another dollar store and within 1/8th mile of an “R” zoning district. The ordinance number is O2023-0004978; read the PDF of the proposed ordinance.

The ordinance would amend the zoning code in chapter 17 as well as add business license regulations in chapter 4 of the Municipal Code of Chicago. The new business licensing section would establish strict rules on “excessive loud noises” and trash accumulation at dollar stores, and even regulate what people outside the store could be doing, as well as require a site plan review by the planning and transportation departments (something usually only required when there is a driveway, drive-through, or larger development).

The city codes would include dollar stores under the new definition of “small box retailer”, which excludes Walgreens and gas station mini marts.

Specifically, “small-box retailer means a retail store (a) with a floor area between 5,000 and 17,500 square feet; (b) that sells at retail an assortment of physical goods, products, or merchandise directly to the consumer, including food or beverages for off-premises consumption, household products, personal grooming and health products, and other consumer goods; (c) that continuously offers and advertises a majority of the items in their inventory for sale at a price less than $5.00 per item; and (d) that does not: (i) contain a prescription pharmacy, (ii) sell gasoline or diesel fuel, (iii) primarily sell specialty food items, or (iv) dedicate less than 5% of shelf space and display areas to food sales.”

The proposal’s purpose is spelled out in the preamble, which makes some judgements about the prevalence of dollar stores in Chicago.

WHEREAS, The City of Chicago (“City”) is a home rule unit of government under Article VII, Section 6(a) of the 1970 Constitution of the State of Illinois and, as such, may exercise any power and perform any function pertaining to its government and affairs, including, but not limited to, the power to regulate for the protection of the public health, safety, and welfare; and

WHEREAS, There is a proliferation of small-box retailers, such as Dollar Tree, Family Dollar (which is owned by Dollar Tree), and Dollar General, in urban areas, including the City, where small-box retailers are clustered in and around South and West Side neighborhoods; and

WHEREAS, Although small-box retailers can fill a need in communities lacking basic retail services, growing evidence suggests small-box retailers are not merely a byproduct of this economic distress, they can often be a cause of it; and

WHEREAS, By saturating communities, particularly majority-Black urban neighborhoods, with multiple stores, small-box retailers’ business strategy often makes it impossible for independent and local grocery stores to open, or, indeed remain open, in a community; and

WHEREAS, Small-box retailers are not a meaningful alternative to local grocery stores, often devoting minimal, if any, floor space to fresh, wholesome foods, and offering low-cost, single serving, highly processed foods that are in actuality much more expensive per ounce; and

WHEREAS, In addition to these negative economic impacts, small-box retailers also tend to attract higher inc dences of crime, theft, and other negative effects on the public health, safety, and welfare, suc as littering and the accumulation of waste far exceeding the dumpster space provided by small-box retailers; and

WHEREAS, Regulating small-box retailers is necessary, desirable, and in the public interest by promoting stronger, more resilient neighborhoods and protecting the public health, safety, and welfare of our Cit ; now, therefore:

Natalie Moore wrote a column in the Chicago Sun-Times about some of the impacts of dollar stores in the city.

Ramifications

If this ordinance went into effect, new dollar stores would only be allowed in the green areas of Chicago. Additional areas would open up if the proposed dollar store would dedicate ≥40 percent of shelf space to fresh or frozen food. This map only considers “Big Dollar” stores and not independent dollar stores that might meet the parameters in the proposed ordinance.

The map below shows 150 locations of Dollar Tree, Dollar General, and Family Dollar stores. Family Dollar is part of Dollar Tree.

The green areas show the parts of Chicago where a new dollar store that follows the default “two mile minimum” rule would be allowed. The proposed ordinance has a provision that if 40 percent or more of shelf space is dedicated to fresh or frozen food then that new dollar store only has to be one mile away from any other dollar store.

It’s possible that dollar store companies could erect stores that are smaller or larger than the floor area standard in the proposed ordinance that would otherwise capture them into the “small box retailer” definition.

A map based on the approved substitute ordinance, showing 1 mile buffer areas, is shown below.

The sweet water sea

I guess some people in the world call large freshwater lakes “sweet water seas”. that would include Lake Michigan, a great lake.

The mouth of Belmont Harbor is a great place to photograph large planes arriving from Europe and Anchorage, charter fishing boats leaving the harbor, and pre- and post-war apartment buildings that overlook Chicago’s precious source of drinking water and recreation.

Why ADUs need to be allowed across Chicago exhibit #42

Alternative headline: The zoning map and the zoning code work hard to limit new housing and density.

Several times a week I browse the descriptions of recently issued building permits in Chicago to find the “interesting” projects so I can post those on the Chicago Cityscape social media accounts and keep people apprised of neat things happening.

I also track when new ADU permits are issued, because the city does not.

Yesterday a permit with the description of “basement to be converted to an additional legal dwelling unit” was issued in Roscoe Village, so I went to the city’s list of ADU pre-approval applications to determine if the permit was for an ADU or the applicant was taking advantage of the property’s #UnusedZoningCapacity.

It was not an ADU, and since it was zoned RS-3 – which bans multi-unit housing – it was also not the owner taking advantage of #UnusedZoningCapacity.

Two-flats of South Chicago
A row of two-flats in Chicago (the one in the story is not pictured).

What was permitted?

I went to the city’s online zoning map to look for other clues, and I found that the property was involved in two Zoning Board of Appeals actions. This is where the story gets interesting. I will do my best to summary the proceedings but I must disclaim that I am not a lawyer.

The Zoning Board of Appeals is an appointed, quasi-judicial body that has three primary functions:

  1. Grant variations where the zoning code authorizes them to (deviations from the code because of atypical circumstances or circumstances that have been previously deemed to require additional review).
  2. Grant special uses where the zoning code authorizes them to (business types that have been previously deemed to require additional or special review).
  3. Appeal decisions made the Zoning Administrator, the person who works for the City of Chicago in the Chicago Department of Planning & Development (and by extension, the plan review staff).

There is a provision in the Chicago zoning code that says that houses that, upon special request, the Zoning Administrator (ZA) can grant an Administrative Adjustment (AA) to allow an additional dwelling unit at houses that are 50 years old or older (subject to other provisions in 17-13-1003-BB).

The owner – also known as the applicant in this blog post – of the two-flat decided to request this AA. The ZA said that the applicant was not eligible for the AA. “The Appellant [applicant] then attempted to seek a variation before the Zoning Board of Appeals” because the ZBA can “grant a variation for any matter expressly authorized as an administrative adjustment”.

Before an applicant can approach ZBA, though, they must apply for a building permit and receive an official “denial of zoning certification” (more on this at the end). This “denial” means, in the unofficial layperson’s zoning translation dictionary, “the permit reviewers see what you’re trying to do and while it’s not permitted as of right under the circumstances you can take this certificate and apply for relief from the ZBA”.

The ZA, who oversees the permit reviewers’ review of a building permit application’s adherence to zoning standards, “refused to issue” the denial. They did this pursuant to 17-16-0503-A, which says the ZA “may deny or withhold all permits, certificates or other forms of authorization on any land or structure or improvements thereon upon which there is uncorrected violation of a provision of this Zoning Ordinance…” The building had an uncorrected building violation citation from 2007.

The property owner disagreed with the application of that section of the zoning code. They filed an appeal and asked the ZBA to reverse the ZA’s decision to refuse issuing the denial. (In the same filing the applicant also asked the ZBA to legalize the basement garden unit, which they declined to do.

I’m going to skip a bunch of the proceedings, which are in the attached meeting minutes from two meetings, but conclude that the ZBA “finds that the ZBA did err in refusing to issue the Appellant an official denial of zoning certification” and ordered the ZA to issue the denial.

The story ended well

Having won the appeal, the applicant has the official denial of zoning certification and can proceed to file a new case with the ZBA and request a variation asking, again, for them to grant them the administrative adjustment that the ZA had previously said the applicant was not eligible for.

The applicant’s building permit for the additional unit was issued on June 7, 2023. The processing time on the building permit was 961 days, which should represent the date when the applicant first submitted the building permit application with the intention of getting the official denial of zoning certification from the ZA.

The result was that the city lost an additional home in a high-amenity, high-resource neighborhood for three years and a property owner had to pay thousands in legal fees.

Attachments

  • 124-22-A. The appeal of the ZA’s denial to issue the official denial of zoning certification.
  • 12-23-Z. The variation granting the property owner the right to establish an additional dwelling unit in the two-flat.

Zoning 101: Business live/work units

This is the first post in what might become a video series about the Chicago zoning code. I picked business live/work unit because they’re a rarely seen “use” (an establishment) in Chicago, likely in part due to how few buildings are zoned to allow them and that the rules setting their minimum size might make eligible spaces doubly harder to find.

There is no order! An authentic “Zoning 101” would probably start by describing zoning, but I’m assuming you know that Chicago has a zoning code that defines what can and cannot be built or practiced on every property in the city. Business live/work units are one of those many things the code defines and regulates.

A business live/work unit is distinguished from an artist live/work unit in the Chicago zoning code in that it allows more business types – i.e. more than the creation or practice of art is allowed – but it requires that they happen on the ground floor. Artist live/work units are allowed in more zoning districts as of right (no additional permission necessary) above the ground floor.
