What if the next great place you live is a historic Chicago Loop office building turned modern home? With more conversions moving forward and new Eastside units on the horizon, you have fresh options in the heart of downtown. You may be weighing rent, timing, and what these projects mean for affordability. In this guide, you’ll learn how conversions get financed, which Loop projects are advancing, and how to plan your next move with confidence. Let’s dive in.
Loop conversions: why now
Downtown office vacancy remains elevated, which is pushing owners and the City to rethink aging towers. Recent reporting shows Chicago’s CBD availability near 29.7% and vacancy about 24.3% in Q2 2025, well above pre‑pandemic levels according to Colliers. In response, the City launched the LaSalle Street Reimagined initiative to add housing, including mixed‑income units, across underused buildings in the Loop. You can explore the City’s program details on the LaSalle initiative page.
Key takeaway: More downtown homes are coming, and many include an affordable component.
What projects are moving in the Loop
Two high‑profile conversions highlight the City’s support for mixed‑income housing in the core:
- 111 W. Monroe: the City approved up to $40 million in TIF to help convert about 315,000 square feet into roughly 345 units.
- 208 S. LaSalle: up to $26 million in TIF to create approximately 168 units on upper floors.
What this means for you: Hundreds of new apartments are planned in the Loop’s most central blocks, with a meaningful share set aside as mixed‑income housing.
How these deals get financed
City TIF fills the gap
Tax Increment Financing helps close feasibility gaps when private debt and equity fall short. The City has approved multi‑million dollar packages for select Loop projects to advance mixed‑income outcomes. See an example of TIF support in the City’s DPD news update.
Historic tax credits add equity
Many Loop buildings qualify for the federal 20% Historic Rehabilitation Tax Credit, which can be syndicated for project equity. Learn the basics on the National Park Service page. Illinois also expanded its state historic credit allocation in recent sessions, offering another potential equity source for qualified projects. See legislative details for SB0119 on the Illinois General Assembly site.
Mixed‑income structures and affordability
When projects include income‑restricted units, sponsors often integrate affordable‑housing tools to finance these components. The LaSalle initiative emphasizes a significant share of mixed‑income housing, which expands access to downtown living.
HUD loans and permanent takeout
For substantial rehabilitation, FHA 221(d)(4) financing is a common construction‑to‑permanent option that can offer high leverage when program criteria are met. Review core requirements on the HUD 221(d)(4) overview. Once a project stabilizes, long‑term permanent loans are widely used to lock in financing and operations.
Bottom line: Conversions typically layer City incentives, tax credits, construction loans, and permanent financing to reach the finish line.
What this means for you
For renters and buyers
New supply in the Loop and adjacent Eastside areas can ease pressure at certain price points over time. Current Loop rents often sit well above citywide averages, with some sources indicating medians around the upper‑$2,000s per RentCafe’s Loop page. Expect more choice, including mixed‑income units created through City‑backed projects. Timing matters, since many conversions deliver in phases.
For sellers and owners
If you own an older downtown office building, rising interest in conversion sites can attract buyers, but underwriting is strict. Feasibility, entitlement path, and public incentives like TIF heavily influence value and timeline. Proof of convertibility and clarity on City approvals are often make‑or‑break.
Timelines and approvals
Most conversions follow a multi‑year path: due diligence, approvals, financing, construction, then lease‑up. In Chicago, a change of occupancy with multiple residential units requires a Department of Buildings review and a Certificate of Occupancy. Learn more on the City’s Certificate of Occupancy resource.
Eastside outlook
You will see momentum spill into the Eastside as central Loop conversions reset demand and bring residents closer to the lakefront, transit, and jobs. With mixed‑income requirements in City‑backed projects, a wider range of price points should reach this part of downtown over time. Keep an eye on phased openings and lease‑up schedules as buildings come online.
Quick checklist: spotting a viable conversion
Use this fast lens when you evaluate a building’s potential or review a new listing in a converted property:
- Floor plate and windows. Narrower plates and ample windows help create bright, code‑compliant homes.
- Ceiling heights. Sufficient floor‑to‑floor space allows modern systems and appealing interior heights.
- Mechanical and plumbing. Added kitchens and baths require new vertical stacks and HVAC adjustments.
- Landmark status. Landmarked buildings can access historic credits, but approvals take time and add design rules.
- Contingency and unknowns. Old envelopes, elevators, and hazardous materials can add cost. Plan for change orders.

FAQs
Is the City paying developers to convert Loop offices?
- Yes. Chicago is using TIF to help select LaSalle corridor projects proceed, with multi‑million dollar packages approved for several conversions. See an example in the City’s TIF support update.
Will these conversions include affordable housing?
- Yes. The LaSalle initiative requires mixed‑income outcomes across projects, which expands access to downtown living. Review the City’s goals on the LaSalle initiative page.
How do historic tax credits help fund projects?
- Qualified rehabs can access a 20% federal historic credit and, in Illinois, potentially layer state credits expanded by recent legislation. Get federal program basics from the National Park Service and see SB0119 on the Illinois General Assembly site.
Can any Loop office building be converted to housing?
- No. Buildings with narrower floor plates, strong window lines, and manageable mechanical upgrades are more viable. Many modern deep‑plate towers are not practical candidates.
How long does a conversion take?
- Expect a multi‑year process from approvals and financing through construction and lease‑up. Chicago requires reviews and a Certificate of Occupancy before opening to residents, which adds time to the schedule.
