Fair share: how many new homes were permitted in your Chicago ward?

Now that I’ve audited the Chicago building permits for the last four years I can more accurately visualize where new homes were permitted across Chicago’s fifty wards. I was not surprised to see that the 27th Ward carries the team known as City Council, but I was surprised by how big the gap was between the first and second place wards, and the gap between the fewest number of wards where 50 percent of new homes were permitted and the number of wards where the other half were permitted.

In the period 2022-2024…

  • 24.0 percent of new homes were permitted in the 27th Ward
  • 10.6 percent in the 34th Ward
  • 8.1 percent in the 3rd Ward
  • 6.9 percent in the 4th Ward

Those four wards comprise 49.5 percent of new homes permitted, while 46 wards permitted the remaining 50.5 percent. Some of this imbalance is due to how different alderpersons accept new development proposals, and the current zoning capacity of properties in each ward.

Incredibly, when rounding to the tenths place, 24 wards permitted so few new homes in that time period that they round down to 0 percent.

To further illustrate how some wards are where so few new homes are permitted, which may be due to factors beyond the alderperson’s control (local rents not meeting development and construction costs, and racism, to name a couple), consider that six wards permitted fewer than 10 homes each during that three-year period.

While Chicago does not have quotas or goals on how many new homes should be permitted or built either citywide or by ward, the city will maintain a housing shortage if most wards are not facilitating or allowing new housing to be built. The allowance of new housing is heavily influenced by each alderperson’s choices.

The city’s ability to grow and spread the property tax revenue burden fairly depends on new development occurring across the city. This is especially the case in areas where new housing can moderate rising demand housing costs, and transportation infrastructure and amenities are in good supply.

Methodology

Using Chicago Department of Building permits that are imported to Chicago Cityscape’s Building Permits Browser, I review each new construction permit’s description to count the number of units authorized by that permit. Foundation phases of multi-phase permits and most revision permits are excluded. I do my best to catch projects that change scope between two permits, such as a permit originally issued for a two-flat but changed to a single-family house, or a larger multifamily building losing or gaining units in a subsequent permit.

New construction coach house units are also excluded because they are allowed only in five pilot areas in a subset of wards; view ADU statistics on Chicago Cityscape.

The statistics are also shown in Chicago Cityscape’s building permits analysis table, which is updated daily; look for columns with a heading that says the year and the word “audited”. Data for permits in other years are not yet reviewed and corrected.

This is an imperfect comparison of wards because there was a redrawing of ward boundaries and an election in 2023. This means that some alderpersons are new, and that all alderpersons oversaw new development approvals and the capacity of their zoning map in different areas before and after the remap.

On the flip side, the new ward map also means that the number of inhabitants in each ward was roughly equal at the time of the remap. This supports some level of data normalization (i.e. new homes permitted per capita), which can be done in future analysis.

The sizable impact of requiring Chicago homeowners to get special use approval to build an ADU

Show your support for a version of the proposed ordinance that enables equal access to ADUs in all residential zoning districts and does not have the carve out explained below by emailing your alderperson and asking that they support ADU expansion into every residential zoning district without special use approval (reference ordinance SO2024-0008918, and then sign this Urban Environmentalists Illinois petition). I spoke about this issue with Mike Stephen on Outside The Loop radio on July 27, 2024 (skip to 6 minutes).

It’s possible that the Chicago City Council votes to approve an ADU expansion ordinance that would require about 38 percent of small-scale residential property owners, specifically in RS-1 and RS-2 zoning districts, to obtain a special use from the Zoning Board of Appeals to build an ADU. Special use approval is intended for limited and certain businesses and building types that can have an adverse impact and may require mitigations that are reviewed and approved by the ZBA.

ADUs have not been demonstrated to have adverse impacts and this potential future requirement would impose burdens on a scale above and beyond anything else the Chicago zoning code imposes. A special use is described in the city’s code as having “widely varying land use and operational characteristics [and] require case-by-case review in order to determine whether they will be compatible with surrounding uses and development patterns. Case-by-case review is intended to ensure consideration of the special use’s anticipated land use, site design and operational impacts.”

Yet an ADU is a residential use; its operational characteristics could not be incompatible with other residential uses. This requirement would be extremely unusual and especially burdensome. There is only one other special use approval that a residential property owner would have to seek, which is to allow housing on the ground floor in B1, B3, C1, and C2 zoning districts.

Applying for a special use for a small home presents a major obligation to the property owner, and requires them to perform the following:

  • Submitting a full building permit application with plans and obtaining a “certificate of zoning denial” before being able to start this process.
  • Paying a $1,000 application fee to the City of Chicago.
  • Hiring an expert witness to write a report and provide testimony at the ZBA hearing.
  • Preparing the finding of fact, a report which (a) describes how the ADU complies with all applicable standards of the Chicago Zoning Ordinance, (b) says that the ADU is in the interest of the public convenience and will not have a significant adverse impact on the general welfare of the neighborhood, (c) explains that the ADU is compatible with the character of the surrounding area in terms of site planning and building scale and project design, (d) states that the ADU is compatible with the character of the surrounding area in terms of operating characteristics, such as hours of operation, outdoor lighting, noise and traffic generation, and (e) outlines that the ADU is designed to promote pedestrian safety and comfort.
  • Preparing the application (which is extensive).
  • Complying with onerous legal notification requirements including determining property owners of record within 250 feet of the subject property, paying for and posting public notice signs and ensuring they remain posted until the public hearing, and mailing notice letters to surrounding property owners within the 250 feet notice radius.
  • Presenting the project to the Zoning Board of Appeals at an undeterminable time during an 8-12 hour meeting in the middle of a Friday, possibly facing one’s neighbors who are present objecting to the project.

Not to mention, this will gum up staff time and expertise.

Scale of impact

I analyzed the number of small-scale residential-only properties in Chicago that would and would not be subject to the special use approval requirement in RS-1 and RS-2 zoning districts if that version were to pass.

The map below shows where the proposed ADU expansion would set a different standard for homeowners in RS-1 and RS-2 zoning districts than for homeowners in all other zoning districts. It covers large parts of 40 percent of the city’s 77 community areas (read more about my thoughts on this in my letter to the Chicago Sun-Times editor).

The table below shows the results of my analysis: the owners of nearly 171,000 small-scale residential properties in RS-1/2 zoning districts would be required to undergo a costly and difficult process that would likely result in burdens so great that very few families would actually be able to take advantage of having an ADU.

“Small-scale residential” comprises Cook County property classifications that represent detached houses, townhouses and townhouses, two-to-six flats, courtyard buildings, and small multifamily buildings, up to 99,999 s.f. with or without commercial space up to 35 percent of the rentable square feet.
