# What the Connected Communities ordinance says in plain language City Council adopted a new TOD ordinance, called "Connected Communities" on Wednesday, July 20, 2022. (Find more articles about #connected-communities .) This is also the third and largest revision of the TOD density bonus and parking reduction rules originally adopted in 2013. [Download ordinance SO2022-2000](https://chicityclerkelms.chicago.gov/Matter/?matterId=A1F5315A-23F4-ED11-A7C6-001DD806ACE0) from the City Clerk's legislation database. The ordinance took effect immediately, which means building permit and zoning change applications submitted after July 20, 2022, must comply with the new zoning code standards. You may notice that the new policies intersect with the Affordable Requirements Ordinance (ARO) and accessible housing standards more than before. I've organized the new standards by theme, starting with the revised definition of a TOD area followed by the brand-new policies. Each theme includes a list of the relevant `Code sections` and some themes have a "potential effect" narrative that interprets the standards in that theme. *Do not construe this as zoning or legal advice for your property or situation. **Table of contents** Themes are numbered in case you want to refer to them in a question or comment, or if you forward part of this to someone else. 1.

Other themes in the new ordinance Plus, we have [[#Additional resources|additional resources]] to learn more about the Connected Communities ordinance. ## 1. TOD areas are bigger A property is considered to be in a TOD area if any part of the property line is within either: * 2,640 feet of a CTA or Metra rail station's entrance or exit. Two new provisions related to rail stations: (a) exits now count, which applies to a lot of Green Line stations on all of its branches; (b) it's no longer required for a property to be on a Pedestrian Street to use the 2,640 feet distance. * 1,320 feet of select CTA or Pace bus route corridors (measured to the roadway centerline). New provision related to bus corridors: The number of bus route corridors greatly expanded, nearly tripling the number of properties in a TOD area. (Bus routes were chosen if they arrived every 15 minutes, or more frequently, between 12 PM and 1 PM on weekdays.) Chicago Cityscape has integrated these expanded TOD areas. We've also kept the old areas so that the old and new code can be compared for a given property. The previous TOD Status section of a Property Report has been renamed to TOD Status pre-2022 and requires a click to open it. ## 2. Bonus unit if ground floor unit is accessible In order to incentivize the quantity of accessible or near-accessible housing, the ordinance exempts ground floor "Type A" dwelling units in buildings with two or more units from the minimum lot area (MLA) per unit and floor area ratio (FAR) calculations in RS-3, RT-3.5, and RT-4 zoning districts. A "Type A" dwelling unit is a new defined term in the zoning code, and has the meaning of a dwelling unit that complies with 14B-11 in the Chicago Building Code. (Refer your [building code questions](https://www.map-strategies.com/blog/2020/7/15/adaptable-accessible-type-a-type-b-mobility-unitswhat-are-the-differences#:~:text=The%20Chicago%20Building%20Code%20explicitly%20states%20in%20Section,constructed%20as%20Accessible%20units%20or%20Type%20A%20units.") to MAP Strategies.) This means a few things for development of multi-flat houses on standard size lots (3,125 s.f., give or take 100 s.f.), regardless of being in a TOD area: * In RS-3 zoning districts all across Chicago, a two-unit house is allowed as of right if there's a dwelling unit on the ground floor that is a "Type A unit" (the existing "60% two-flats on the same street in RS-3 districts" rule is bypassed here). The allowable building height is unchanged. * In RT-3.5 zoning districts, a three-unit house is allowed as of right for the same reason as above. The allowable building height is unchanged; units could be arranged differently than the typical three-flat - see the [Kinexx back-to-back townhouse](https://www.chicagocityscape.com/blog/chicago-s-first-two-unit-modular-house-is-constructed-more-are-on-the-way-0f225ce7d5), for example. * In RT-4 zoning districts, a four-unit house is allowed as of right for the same reason as above. Additionally, the allowable building height is increased from 38 feet to 42 feet. Because of this new rule, the RT-4A zoning district, which only existed on the zoning map if a property owner got a zoning change for it, has been eliminated from the zoning code. Tip: Use the [[Value add properties|value add filters]] to find properties where the "extra unit" (if made accessible) is allowed. This will enable a filter that causes Property Finder to look for properties that has one of the three eligible zoning districts. ### Parking for those accessible units The associated parking rule has also changed: The minimum number of parking spaces is one (1) space per eight feet (8') of alley frontage, and an accessible parking space counts as two (2) spaces. ### Code sections 17-2-0303-B (ground floor accessible units are exempt from MLA per dwelling unit calculations in RS-3, RT-3.5, and RT-4 zoning districts), 17-2-0304-D (ground floor accessible units are not counted as floor area for the purpose of calculating floor area ratio in RS-3, RT-3.5, and RT-4 zoning districts), 17-10-0102-F (parking count) ### Potential effects 1. In RT-4 zoning districts, picture the typical three-flat condo buildings where the lowest level unit is duplexed down to a partial basement floor. Here, the property owner can, alternatively, build a three-flat over four above-ground levels as long as the ground floor unit is a Type A unit. 2. Another alternative would be to build a four-flat with four above-ground levels as long as the ground floor unit is a Type A unit. 3. The third example is to find a double lot zoned RT-4 in a TOD area and develop 8 units with only 4 car parking spaces (each accessible parking space counts as 2 spaces). There would have to be at least one Type A dwelling unit. The first known project to take advantage of the accessibility provision in Connected Communities is [this project by Langford Construction at 4861 N Hermitage Ave](/ordinances.php?ordinance=9427). It takes advantage of 2 of the 4 standards: Height increase and parking count. It was not in need of the FAR or MLA per unit exemption because it's an oversized lot that had sufficient allowance already. `Code sections`: [17-2-0303-B(2)](https://codelibrary.amlegal.com/codes/chicago/latest/chicagozoning_il/0-0-0-48935), 17-2-0304-D, 17-2-0311-B(2), and 17-10-0102-F ## 3. Minimum density housing and stopping deconversions The ordinance greatly expands the anti-deconversion and minimum density rules that were put in place around the 606 and in most of Pilsen in 2020. The Connected Communities ordinance establishes that two-flats or three-flats are the minimum house size in TOD areas that are also at risk of deconversion and displacement. Properties that are zoned RT, RM, B, or C, and that are (1) within an ARO Community Preservation Area and (2) within a TOD area (the two geographic standards) _cannot have a detached house_ unless and until it is rezoned to an RS zoning district. This means an existing multi-flat house cannot be deconverted to a single-family house on thousands of properties across Chicago. * In RT zoning districts that also meet the two geographic standards, a two-flat is the minimum house size that can be built. There is an exception, which I will paraphrase by giving a practical example: If the lot size is smaller than 2,000 s.f. then a detached house can be built (there is an exception to this that would allow a two-flat to be built on a 1,800 s.f. lot; see [17-13-1003-A](https://codelibrary.amlegal.com/codes/chicago/latest/chicagozoning_il/0-0-0-51818)). * In RM zoning districts that also meet the two geographic standards, a three-flat is the minimum house size that can be built. There are two exceptions, which I will paraphrase by giving two practical examples: If the lot size is smaller than 2,100 s.f. then a two-flat can be built, and if the lot size is smaller than 1,400 s.f. then a detached house can be built (there is exception to these exceptions; see 17-13-1003-A). * In B and C zoning districts that also meet the two geographic standards, a three-flat is the minimum house size that can be built. The standards to require or not require ground floor commercial space remains unchanged. Similar to the exceptions above, if bulk and density standards do not allow a three-flat to be established, a two-flat may be established, and where a two-flat cannot be established, only then can a detached house be established. ### Potential effect In the East Garfield Park community area, there are currently approximately 1,692 2-6 flat houses in RT and RM districts and the Community Preservation Area that this rule applies to. An owner of a multi-flat house in that group of properties cannot deconvert it to a detached house. Also within that group, there are about 167 houses in RM districts with three or more units; these owners cannot deconvert them to detached houses nor to two-flats. <code>Code sections</code>: 17-2-0303-B(3) and 17-2-0303-B(4) [RT and RM districts]; 17-3-0307(2) and 17-3-0307(4) [B and C districts] ## 4. New bike parking rules The new ordinance requires developments – new and conversions – in a TOD area one bicycle parking space for each dwelling unit. Previous rules for providing bicycle parking in non-residential projects remain. Bicycle parking caps still do not apply to developments in TOD areas. ### Note This rule applies in RM-5, RM-5.5, RM-6, RM-6.5, and B, C, D, M, and PMD subareas B, zoning districts. It is new for this to apply in RM and PMD zoning districts. <code>Code sections</code>: 17-10-0102-B(2) ## 5. Parking maximums & where parking reductions are allowed This theme summarizes three related sets of rules. <h3>Set A - Maximum car parking in B, C, D, M, and PMD areas</h3> The ordinance introduces car parking maximum standards outside of D zoning districts for the first time, in B and C districts in TOD areas, and the standards in D districts have been modified somewhat. * Residential projects in TOD areas + B, C, D districts: The required number of spaces in these districts for residential projects is 50 percent of the number in the zoning code's parking table in chapter 17-10. The minimum number is 0 spaces, and an administrative adjustment or PD is required to provide less than or more than 50 percent of the parking required by the zoning code's parking table in chapter 17-10. Preexisting maximum standards for projects in D districts may also apply. For residential projects in B, C, and D districts and in rail station TOD areas, the zoning administrator can approve an amount greater than 50 percent of the number in the parking table, up to 100 percent of (i.e. equivalent to) the required parking in the parking table. Note: the cap ("up to 100 percent") does not apply in bus corridor-only TOD areas. * Non-residential projects in TOD areas + D districts: The maximum number of spaces in D districts for non-residential projects is established in the zoning code's parking table in chapter 10 and in the preexisting code standards. The minimum number is 0 spaces, and an administrative adjustment or PD is required to provide less than 50 percent of the parking required by the zoning code's parking table in chapter 10. * Non-residential projects in TOD areas + B, C, M, and PMD subareas B, districts: There is no maximum number of spaces allowed. The minimum number is 0 spaces, and an administrative adjustment or PD is required to provide less than 50 percent of the parking required by the zoning code's parking table in chapter 17-10. An administrative adjustment is required to provide less than 50 percent of the required parking in the chapter 10 parking table _and_ is required to provide more than 50 percent of the required parking in the chapter 17-10 parking table. Resource: [Information on how to request and apply for an administrative adjustment](https://www.chicago.gov/city/en/depts/dcd/supp_info/administrative_adjustments.html). Tip: Previously, projects could reduce their parking requirement by up to 50 percent as of right. To reduce more than 50 percent, a Type 1 zoning map amendment, special use, or Planned Development approval was required. <h3>Set B - RM districts and PMD subarea B areas</h3> In addition to the previous TOD ordinance's provision that parking reductions were allowed at properties in B, C, D, M, and PMD subareas B, zoning districts and in a TOD area, the Connected Communities ordinance extends those reductions to properties in RM-5 (and higher) districts and the PMD subareas B (and also within a TOD area). Let's call these in Set A and Set B the _primary_ parking reduction zoning districts standard. <i class="fad fa-lightbulb-on" aria-hidden="true"></i> Tip: In RM-5, RM-5.5, RM-6, and RM-6.5 zoning districts, it would be possible to build a six-unit house with 3 car parking spaces as of right or with 0 car parking spaces by obtaining an administrative adjustment. [Learn more about the "Standard 6-3"](/guide/standard6383) <i class="fad fa-lightbulb-on" aria-hidden="true"></i> Tip: Learn how to use Chicago Cityscape's Property Finder to identify properties in bulk that are within a TOD area and within a parking reduction zoning district. [Go to that Knowledge Base article](/guide/parkingreduction) It's also easier to achieve a reduction in required car parking greater than the by-right reduction of 50 percent. In fact, one car parking space per two dwelling units is now the standard amount required. An administrative adjustment is required to be able to provide more parking than this as well as less parking than this (see also Theme 9). <i class="fad fa-history" aria-hidden="true"></i> Previously, the property owner would have to apply for and receive approval via special use, Type 1 zoning map amendment, or the Planned Development process to take a reduction larger than 50 percent. The parking maximum for residential developments described in Set A above do not apply to RM zoning districts. ### Set C - Parking for affordable housing developments The second provision is a parking reduction available in all zoning districts, including R districts, which is new; let's call this the _expanded_ parking reduction districts standard. (In Property Finder, you can filter for these by selecting "TOD expand. parking districts" in the zoning districts filter _and_ selecting the "Chicago TOD/TSL" filter.) <i class="fad fa-lightbulb-on" aria-hidden="true"></i> Tip: Learn how to use Chicago Cityscape's Property Finder to identify properties in bulk that are within a TOD area and within a parking reduction zoning district. [Go to that Knowledge Base article](/guide/parkingreduction) For projects in a TOD area, car parking requirements can be reduced by up to 100 percent if 50 percent or more of the dwelling units are either (a) assisted housing or affordable units, or (b) 50 percent or more of the dwelling units are income restricted to households earning no more than 80 percent of the Area Median Income and that fact is documented by a recorded or regulatory instrument. An administrative adjustment is not necessarily be required, and the provision is also applicable in RS and RT zoning districts. ### Potential effect The development of low-density affordable housing in RS and RT zoning districts – say, Habitat for Humanity or Chicago Housing Trust or land trust houses – could be exempted from having to provide any car parking, which could have the effect of reducing construction costs and allowing more backyard space, or allowing development on smaller (less deep) lots. I don't particularly think this will happen often, but it's a possibility. ### Note The special rule in the zoning code prior to the adoption of Connected Communities that applied only to properties within RM-6 and RM-6.5 zoning districts and within 250 feet of a CTA station that was established in 2012 (one year prior to the TOD ordinance) has been struck from the zoning code; this was section 17-10-0102-B(5). This special rule was established primarily to permit the construction of a single building, 1215 W Division Street, to allow for the developer who wanted to provide zero car parking spaces for the residential portion of the building. If requesting two or more administrative adjustments for a new construction project (for example, to increase the parking for condos and decrease the parking for apartments) then the applicant must request the changes as a variation, from the Zoning Board of Appeals. <code>Code sections</code> - 17-10-0102-B(1), _primary_ parking reduction districts, and 17-10-0102-B(4), _expanded_ parking reduction districts - 17-10-0207, chapter 17-10 parking table - 17-13-1003-EE(1), administrative adjustment for getting to 0 car parking spaces - 17-13-1003-EE(2) administrative adjustment for maximizing allowed residential car parking] in B and C zoning districts - 17-13-1003-EE(3), administrative adjustment for maximizing allowed residential car parking in D zoning districts - 17-10-0205, downtown parking maximums that predate the TOD ordinance - 17-10-0102-E, downtown parking waiver ## 6. Trading reduced parking area for more floor area and dwelling units A provision allows certain Planned Developments (PDs) to convert or swap floor area that would have been used for required car parking if the development wasn't in a TOD area to floor area for more dwelling units. (This is known as the **parking swap bonus** and it was [first used by the Fern Hill project at 2358 S Michigan Ave in June 2024](https://elevatedchicago.org/two-etod-firsts-in-chicago-happened-in-june/).) Example: A proposed PD in a TOD area has 100 dwelling units and thus 50 car parking spaces are required (ignore that there might also be a parking cap in downtown districts, which predate the TOD ordinance). The proposer intends to provide only 20 of those car parking spaces (and obtains this reduction below 50 spaces through the PD approval process). Because of the ARO, 5 of the units must be on-site affordable (the other 15 required ARO units can be established pursuant to other rules governing the specific project location). Since floor area for required car parking doesn't count towards FAR, reducing the floor area dedicated to the required car parking doesn't change the FAR and thus that floor area cannot be used for other uses the proposer would rather provide (like commercial space or more dwelling units). As long as certain conditions are met, the floor area that would have been used for the 30 car parking spaces that would have been otherwise required can be used for additional dwelling units. Each additional unit added because of this provision must be accompanied by an additional affordable dwelling unit. Those conditions are: It proposed project meets the requirements for a mandatory PD, the development provides the maximum number of efficiency units (i.e. studio apartments), the FAR is maximized, the floor area is used only for additional units and not enlarging the additional units allowed for by the TOD area density bonus, no more than 50 percent of the otherwise required car parking is provided, the floor area is used to provide the new dwelling units in the same building where the car parking is being replaced, and the minimum number of on-site ARO units that are required in the proposal is recalculated to incorporate the additional units allowed by this provision. ### Potential effect In the example above, the 30 car parking spaces not built are equivalent to 10,500 s.f. (this assumes each parking space and associated aisle and maneuvering space is equivalent to 350 s.f.). Assuming the proposer wants to add more one bedroom units that are each 800 s.f., the development could add about 13 additional units – not considering the space for building corridors – for a total of 113 units. Half of the additional units – 7, when rounding up – must be affordable. <code>Code sections</code>: 17-10-0102-B(4), 17-17-0305-A(8) and 17-10-0205 [sections that establish the 350 s.f. parking space equivalency standard]; 17-17-0305-B [exempting parking areas from floor area calculation] ## 7. Modified density bonus standards The density bonus standards in the TOD ordinance have only ever applied in B, C, and D zoning districts with a "dash 3" density designation and that standard remains. What's changed is that the amount of bonus – to minimum lot area (MLA) per unit standards and to floor area ratio (FAR) standards – is related to the amount of ARO units that are provided on-site. In the previous version of the TOD ordinance, the MLA for dwelling units (excluding efficiency and SRO units) was reduced from 400 to 300 s.f. across the board. In the Connected Communities ordinance, projects that build 25 percent of their required ARO units on-site cannot obtain an MLA reduction through this provision. Projects that build 50 percent of their required ARO units on-site can use a 350 s.f.. MLA per unit; at 75 percent, the MLA is 325 s.f per unit, and at 100 percent the MLA is 300 s.f. per unit. Likewise with FAR, projects that build 25 percent of their required ARO units on-site cannot obtain a FAR bonus through this provision. Projects that build 50 percent of their required ARO units on-site can have an FAR of 3.5 (an increase of 0.5 over the "dash 3" FAR of 3.0); at 75 percent the FAR bonus is 0.75 (total of 3.75), and at 100 percent the FAR bonus is 1.0 (total of 4.0). ### Potential effect The obvious intent is to incentivize more affordable housing to be built on site than the ARO requires. This coupled with the "trade" option in theme 6 could be used to build a lot more market rate and affordable housing in the same proposed project. There's an unanswered question, though, however impractical or infrequent my specific example may sound: If the owner of a smaller building with four units, for example, wants to add two units and needs the MLA reduction or FAR bonus, or both, in order to do so and is willing to obtain a Type 1 zoning map amendment in order to do so, it appears that neither would be available unless the property owner also made one of the two units affordable, which the ARO does not require because the proposed expansion would not trigger ARO compliance. ### Note The building height bonus is unchanged. A new exception was added to allow exceeding the maximum building height standard for buildings in B and C districts that have 100 feet or more of lot frontage. The increase can be obtained in "dash 3" districts if the project is reviewed and approved using the Planned Development process. Additionally, a Type 1 zoning map amendment or Planned Development (mandatory or elective) is still required to obtain either the MLA reduction or the FAR bonus. <code>Code sections</code>: 17-3-0402-B and 17-3-0403-B [B and C districts]; 17-4-0405-D and 17-4-0405-C [D districts] ## 8. Approval timeline (shot clock) This is a completely new provision, but is similar to an ordinance that was [proposed to City Council in 2018](https://blog.chicagocityscape.com/city-council-members-have-their-own-affordable-housing-initiatives-4b3f181dcde0). In order to provide project proposers a little more certainty, the City Council is required to vote on projects. If a proposed project requires a zoning change and it is an "inclusionary application", then the zoning committee must vote on it within 300 days or it can be automatically approved by the committee 60 days later upon receipt of a petition from the applicant (known in some jurisdictions, including across California, as a "shot clock"). At least one community meeting must have been held for that project. Slightly different rules apply if the inclusionary application is for an amendment to a Planned Development. If a proposed project requires a zoning change and it is not an "inclusionary application", then the zoning committee must vote on it within 180 days. If they do not, then the project becomes automatically denied by the committee. An inclusionary application is one that is in a TOD area, requires the Planned Development process or is requesting a Type 1 zoning map amendment, is in an ARO inclusionary housing area (see our [ARO map](https://www.chicagocityscape.com/maps/aro2021.php)), and has either (a) all required ARO units on-site, or (b) 20 percent or more of the units are subject to a recorded or regulatory instrument. Note: As of December 12, 2024, the inclusionary application provision has not been used. However, it may be the case that 1840 N Marcey St gets approved this way (see this [Crain's article](https://www.chicagobusiness.com/politics/lincoln-park-apartment-project-avoid-city-council-rejection) from December 11, 2024). ### Code sections - 17-13-0309 - 17-13-0608 - 17-17-0207.5 (definition of "inclusionary application") ## 9. Pedestrian Street standards now apply more often In the previous ordinance proposed developments in B, C, and D districts would have to comply with Pedestrian Street standards if the project was providing less than 50 percent of the required car parking. ([[Pedestrian Streets|Learn more about Pedestrian Streets]].) In the new ordinance, "any new construction" in B, C, and D districts within 2,640 feet of a CTA or Metra rail station entrance will have to comply with Pedestrian Street standards, except that the permitted uses standard in the Pedestrian Street code applies only to developments actually on a Pedestrian Street. Tip: Every [Property Report lookup](https://www.chicagocityscape.com/address.php) for a Chicago address or property will measure the distance. ### Potential impact One of the Pedestrian Street standards that the project must comply with is no new curb cuts or driveways, which disturb the pedestrian-oriented nature of many streets, unless an #administrative-adjustment is obtained. The standard in the Pedestrian Street code that prohibits car-oriented land uses does not apply to these projects unless that project is actually on a Pedestrian Street. ### Note A Pedestrian Street is a zoning code term and specific blocks are designated by City Council ([see our map of Pedestrian Streets](https://www.chicagocityscape.com/maps/index.php#/?places_type=chipedstreet)), and not a pedestrianized street where vehicles are prohibited or severely restricted. <code>Code sections</code>: 17-3-0308 [B/C districts], 17-3-0504 [B/C districts], 17-4-0301 [D districts], and 17-10-0102-B [parking] ## 10. Other themes in the new ordinance * All new construction in B, C, and D districts must conform to the Pedestrian Street standards, which is addressed in Theme 9. The projects must also comply with Travel (Transportation) Demand Study and Management Plan rules. <code>Code sections</code>: 17-3-0308 and 17-4-0301 – see also [[Transportation Demand Management]]. * The rule allowing an additional unit in an older building has been changed to require the property owner to show proof that the additional unit has been in place for 20 years or more. The previous code required proof showing that the unit had been in place for 50 years or more. <code>Code section</code>: 17-13-1003-BB * Accessible parking design standards and passenger loading zones have been modified. <code>Code section</code>: 17-10-0904 * The definition of a single-room occupancy (SRO) unit has been expanded to recognize that older SRO units may not comply with the previous definition. <code>Code section</code>: 17-17-02164 * Rules governing the height of photovoltaic solar panels have been added to the zoning code, and they apply in all zoning districts. <code>Code section</code>: 17-17-0311-B * There are new rules governing the bulk of stairway and elevator enclosures and elevator equipment penthouses in all zoning districts. <code>Code section</code>: 17-17-0311-C ## Additional resources - Find examples of Connected Communities building permits using [Building Permits Browser's](https://chicagocityscape.com/permits.php) "Filter by tag or topic" - [Find examples of Connected Communities projects](https://chicagocityscape.com/tag/connectedcommunities) - [Information on how to request and apply for an administrative adjustment](https://www.chicago.gov/city/en/depts/dcd/supp_info/administrative_adjustments.html) - [City of Chicago, Department of housing "one pagers"](https://www.chicago.gov/city/en/sites/equitable-transit-oriented-development/home/connected-communities-ordinance.html) - [Chicago City Council Expands Transit-Served Location Zoning Regulations](https://www.elrodfriedman.com/news-and-insights/chicago-city-council-expands-transit-served-location-zoning-regulations/) by Liz Butler, a land use attorney - [City Council passes Connected Communities Ordinance](https://chicago.urbanize.city/post/city-council-passes-connected-communities-ordinance) by Lukas Kugler - [Real Estate Toolbox Series: Chicago’s New eTOD Ordinance: What You Need to Know](https://sttcdotcomcdnprod1dc8fb.blob.core.windows.net/content/marketing/eTOD%20Presentation.pdf) by Thompson Coburn attorneys Katriina McGuire and Talar Berberian
