Chicago ADU Frequently Asked Questions
Everything you need to know about Accessory Dwelling Units in Chicago
An Accessory Dwelling Unit (ADU) in Chicago is a secondary housing unit located on the same lot as a primary residence. ADUs can take various forms, including coach houses (above garages), basement apartments, attic apartments, or standalone backyard cottages. They are self-contained living spaces with their own kitchen, bathroom, living area, and separate entrance.
Yes, ADUs are legal in Chicago. In December 2020, the Chicago City Council passed an ordinance allowing for the construction of ADUs in five designated pilot areas across the city. This ordinance ended a 63-year ban on new coach houses and similar structures in these areas. Areas outside the pilot zones may have different regulations regarding ADUs.
The five designated ADU pilot areas in Chicago are:
- North: Parts of Albany Park, Irving Park, North Park, West Ridge
- Northwest: Parts of Avondale, Hermosa, Logan Square, Near West Side
- West: Parts of East Garfield Park, North Lawndale, South Lawndale, West Garfield Park
- South: Parts of Ashburn, Auburn Gresham, Chicago Lawn, Englewood
- Southeast: Parts of South Chicago, South Shore, Woodlawn
Chicago's ADU ordinance allows for several types of ADUs:
- Coach Houses: Dwelling units above detached garages
- Conversion Units: Created within existing single-family homes or multi-unit buildings (basement, attic, or other conversions)
- Backyard Houses: Standalone structures in the rear yard
Building an ADU in Chicago offers numerous benefits:
- Generate rental income to help offset mortgage costs or provide additional income
- Create housing for family members (aging parents, adult children, etc.)
- Increase your property value
- Provide affordable housing options in your neighborhood
- Make use of underutilized space on your property
- Create flexible living arrangements that can change over time based on your needs
- Contribute to a more sustainable, walkable neighborhood with increased density
Chicago's ADU size requirements vary by type:
- Conversion Units: No maximum size limit, but must comply with building code requirements
- Coach Houses: Maximum size is 60% of the footprint of the principal building or 700 square feet, whichever is less
- Backyard Houses: Maximum size is 60% of the footprint of the principal building or 700 square feet, whichever is less
No, Chicago's ADU ordinance does not require additional parking spaces for ADUs. This is a significant advantage of the new regulations, as it removes a common barrier to ADU development. However, you may want to consider the impact on street parking in your neighborhood and whether providing additional off-street parking would be beneficial for your specific situation.
Height restrictions for ADUs in Chicago depend on the type:
- Coach Houses: Maximum height is 22 feet
- Backyard Houses: Maximum height is 22 feet
- Conversion Units: Must comply with existing building height restrictions for the primary structure
Yes, Chicago ADUs must comply with setback requirements:
- Coach Houses: Must be located in the rear of the property with a minimum 2-foot setback from rear and side property lines
- Backyard Houses: Require a minimum 2-foot setback from rear and side property lines
- Conversion Units: No additional setback requirements beyond those that apply to the existing structure
The number of ADUs allowed depends on your property type:
- Single-family homes: Can add one conversion unit and one coach house or backyard house
- Two-to-four unit buildings: Can add up to two conversion units within the main building and one coach house/backyard house
- Larger multi-unit buildings: Can add ADUs totaling up to one-third of the existing number of units (minimum of one, maximum of three)
Building an ADU in Chicago typically requires several permits:
- Building Permit: For the overall construction
- Electrical Permit: For all electrical work
- Plumbing Permit: For all plumbing installations
- Mechanical Permit: For HVAC systems
- Demolition Permit: If removing existing structures
The permitting timeline for Chicago ADUs varies depending on several factors including the complexity of your project, the completeness of your application, and the current workload of the building department. Typically, you can expect:
- Simple conversion units: 2-4 months for permit approval
- New construction (coach houses or backyard houses): 3-6 months for permit approval
Yes, you'll need professional architectural plans for your Chicago ADU. The City of Chicago requires stamped architectural drawings for building permit applications. These plans must include:
- Site plan showing property boundaries and the location of existing and proposed structures
- Floor plans with dimensions, room layouts, and door/window locations
- Elevations showing exterior appearance and height
- Structural details including foundation plans and framing
- Electrical, plumbing, and mechanical plans
- Energy compliance documentation
Chicago ADU projects typically require several inspections throughout the construction process:
- Foundation Inspection: Before pouring concrete
- Framing Inspection: After framing is complete but before walls are closed up
- Rough Plumbing Inspection: Before walls are closed
- Rough Electrical Inspection: Before walls are closed
- Rough HVAC Inspection: Before walls are closed
- Insulation Inspection: After insulation is installed but before drywall
- Final Inspections: For all systems after construction is complete
The cost of building an ADU in Chicago varies based on the type, size, and finishes:
- Conversion Units (basement or attic): Generally $100,000 to $250,000, depending on existing conditions and finishes
- Coach Houses: Typically $200,000 to $400,000, depending on size and quality
- Backyard Houses: Usually $250,000 to $450,000+, depending on size and quality
The construction timeline for a Chicago ADU typically ranges:
- Planning and Design Phase: 1-3 months
- Permitting: 2-6 months (depending on project complexity)
- Construction:
- Conversion Units: 3-6 months
- Coach Houses: 4-8 months
- Backyard Houses: 5-9 months
Chicago ADUs require the following utilities:
- Electrical: ADUs must have their own electrical service, which can be connected to the main building's service or have a separate meter
- Plumbing: Water supply, sewer connection, and hot water heater
- Heating and Cooling: ADUs must have adequate heating for Chicago winters, with options including forced air, radiators, or ductless mini-splits
- Gas: Optional, depending on heating and appliance choices
- Internet/Cable: Not required by code but typically desired
Yes, building an ADU over a garage (a coach house) is one of the most popular ADU options in Chicago. The ADU ordinance specifically allows for coach houses in all five pilot areas. Key considerations for garage ADUs include:
- Your existing garage must be structurally sound or may need reinforcement to support the ADU
- Maximum height is 22 feet
- Maximum size is 60% of the footprint of the principal building or 700 square feet, whichever is less
- You'll need proper stair access that meets building code requirements
- Utility connections must be planned carefully
Chicago ADUs must comply with accessibility requirements based on their type:
- Ground-floor and Backyard ADUs: Must meet Type B (adaptable) unit requirements, including accessible routes, wider doorways, and bathroom walls that can support grab bars
- Upper-floor Conversion Units and Coach Houses: May be exempt from some accessibility requirements if they're only accessible by stairs
- Units in larger multi-unit buildings: May have additional accessibility requirements
Several financing options are available for Chicago ADU projects:
- Home Equity Loan or Line of Credit (HELOC): Uses the equity in your home to finance the ADU
- Cash-Out Refinancing: Refinance your existing mortgage for more than you owe and use the difference for the ADU
- Construction Loans: Specifically designed for building projects
- Renovation Loans: Like FHA 203k or Fannie Mae HomeStyle loans that can be used for ADU construction
- Personal Loans: For smaller ADU projects
- Chicago-specific Programs: Such as the Additional Dwelling Unit Improvement Program or neighborhood improvement grants
Yes, adding an ADU will likely increase your property taxes in Chicago. The amount of increase depends on several factors:
- The value added to your property by the ADU
- The size and quality of the ADU
- The current assessed value of your property
- Your property's location within Chicago
Potential rental income for a Chicago ADU varies significantly based on:
- Location: Neighborhood demand and desirability
- Size: Studio, one-bedroom, or two-bedroom unit
- Quality: Finishes, amenities, and overall appeal
- Access to transit: Proximity to CTA trains, buses, etc.
- Studios: $900-$1,500 per month
- One-bedrooms: $1,200-$2,000 per month
- Two-bedrooms: $1,500-$2,500+ per month
The ROI for a Chicago ADU typically includes:
- Rental Income: Consistent monthly revenue from tenants
- Property Value Increase: ADUs generally add more value to your property than they cost to build
- Appreciation: The ADU appreciates along with your property over time
Chicago's ADU ordinance specifically prohibits using ADUs for short-term rentals (less than 30 days) like Airbnb or VRBO. This restriction was included to ensure ADUs contribute to the city's long-term housing supply rather than the tourism market. ADUs must be rented for periods of 30 days or longer. Violations of this requirement can result in fines and other penalties. However, ADUs are excellent for long-term rentals, family housing, or home offices.
No, Chicago's ADU ordinance does not include an owner-occupancy requirement. You can build an ADU and rent out both the ADU and the primary residence. This flexibility makes ADUs attractive to investors and homeowners alike. However, some financing options might have their own owner-occupancy requirements, so it's important to check with your lender if you're financing the ADU construction.
No, Chicago's ADU ordinance does not allow ADUs to be sold separately from the principal dwelling. ADUs cannot have separate property tax bills or be legally subdivided from the main property. This is consistent with most ADU regulations across the country. If you want to create housing units that can be sold separately, you would need to pursue a different process such as a condominium conversion or lot subdivision, which have their own requirements and restrictions.
Yes, you should update your homeowner's insurance policy to cover your ADU. This typically involves:
- Increasing your dwelling coverage to include the value of the ADU
- If renting the ADU, adding landlord coverage or a rental dwelling policy
- Considering additional liability coverage
- Possibly recommending renter's insurance for your tenants
Chicago has a long history with ADUs:
- Pre-1957: Coach houses and converted units were common throughout Chicago
- 1957: Chicago banned new coach houses and limited dwelling unit density in most neighborhoods
- 1957-2020: Existing ADUs were grandfathered in, but no new ones could be built in most areas
- December 2020: Chicago City Council passed the Additional Dwelling Unit ordinance creating five pilot areas where ADUs are now permitted
- May 2021: The ADU ordinance took effect, allowing the construction of new ADUs in the designated areas
The City of Chicago is monitoring the results of the ADU pilot program with the intention of potentially expanding it to other areas. The current ordinance includes provisions for evaluation after three years (around 2024). Based on the success of the program, feedback from communities, and housing needs, the city may:
- Expand the eligible areas for ADUs
- Modify requirements based on lessons learned
- Potentially make ADUs legal throughout the entire city
Chicago's ADU ordinance includes some affordable housing provisions:
- In buildings with 6+ units, at least half of the new ADUs must be maintained as affordable housing for 30 years
- For smaller properties (single-family to 5 units), there are no specific affordability requirements
- Additional incentives are available for property owners who choose to designate their ADUs as affordable housing
