Mayor Brandon Johnson and R2 Development celebrated the grand opening of The Bellwether Residences at 79 W. Monroe Street on September 9, 2026, marking the first completed office-to-residential conversion under Chicago’s LaSalle Street Corridor Revitalization program. The $64.2 million project converted 11 floors of the historic 1905 Rector Building into 117 residential units, including 41 affordable units set aside under the Affordable Requirements Ordinance. R2 Companies received $28 million in Tax Increment Financing from the city to underwrite the adaptive reuse. RMK Management Corp., one of the Midwest’s largest market-rate apartment management firms, is handling leasing and property management, and the building was already 57% leased at the time of the grand opening.
Key Takeaways
- The Bellwether Residences at 79 W. Monroe is the first completed office-to-residential conversion under Chicago’s LaSalle Street Corridor Revitalization program, celebrating its grand opening on September 9, 2026.
- The $64.2 million project converted 11 floors of the historic 1905 Rector Building into 117 apartments, including 41 affordable units; R2 Companies received $28 million in TIF funding from the city.
- Units range from studios to two-bedrooms at 425 to 1,178 square feet, with rents from $1,996 to $4,887 per month; the building was 57% leased at grand opening.

A 1905 Building Gets a New Life After Decades as Office Space and a Bank Headquarters
The Bellwether occupies the former Rector Building at the corner of Clark and Monroe Streets, a 14-story structure originally built in 1905 and expanded significantly in 1924. Over its 121-year history, the building served as office space and a bank headquarters, cycling through tenants as the Loop’s commercial identity evolved around it. By the time R2 Companies began redevelopment in 2025, the building had joined a growing inventory of older Loop office properties that were struggling to attract tenants in a post-pandemic market where remote and hybrid work had permanently reduced demand for traditional five-day office space.
The adaptive reuse converted the upper floors into 117 residential units while preserving architectural details that reflect the building’s age and character. RMK Management Corp. described the interiors as pairing modern finishes with the structure’s original features, including ornamental metal detailing on staircases and railings and vintage tile patterns in common areas. Units feature hardwood flooring, quartz countertops, tile backsplashes, stainless steel appliances, in-unit laundry, and walk-in closets, with kitchen islands in select floor plans.
The project is the latest example of Chicago converting underutilized institutional buildings into housing. Across the city, that approach is taking different forms depending on the building type and neighborhood context. On the South Side, a former West Englewood school that sat vacant for 13 years recently reopened as a 50-unit affordable housing development, demonstrating that the adaptive reuse model extends beyond the Loop’s commercial towers into neighborhood buildings that have been empty since Chicago’s mass school closures in 2013.
The LaSalle Street Corridor Program Aims to Add More Than 1,000 Apartments to the Loop
The Bellwether is the first of six projects planned under the LaSalle Street Corridor Revitalization program, a city initiative that uses private funding and Tax Increment Financing to convert largely vacant office buildings in the Loop into mixed-income residential communities. The program was designed as a direct response to the structural shift in how downtowns function after the pandemic, recognizing that the old model of a central business district dominated by offices five days a week no longer matches the reality of how companies and workers use urban space.
Alderman Bill Conway of the 34th Ward framed the strategy at the grand opening: COVID fundamentally changed downtowns across the country and around the world, and to keep downtown Chicago vibrant, the city is transforming it into a true mixed-use neighborhood where people work but also live, eat, shop, and raise families. The program is expected to bring more than 1,000 apartments to the LaSalle Street corridor once all six projects are completed, adding a residential population to a stretch of downtown that has historically emptied out after business hours.
The Bellwether’s $28 million in TIF funding represents a significant public subsidy, but the city’s calculation is that the cost of leaving aging office towers vacant — in lost property tax revenue, reduced foot traffic, and the cascading effect on surrounding retail and restaurants — exceeds the cost of investing in their conversion. The 41 affordable units included in The Bellwether satisfy the Affordable Requirements Ordinance and ensure that the new residential population reflects a range of income levels rather than serving exclusively as market-rate housing.
Downtown Office Vacancy Remains at Historic Highs, Strengthening the Case for Conversion
The economic context for The Bellwether is defined by a number that has not improved meaningfully since 2023: CBRE reported 26.8% direct Downtown office vacancy in Q2 2026, with cumulative net absorption — the measure of how much occupied space is growing or shrinking — remaining negative for more than three consecutive years. That means the total amount of occupied office space in downtown Chicago has been declining quarter after quarter, even as some individual buildings have signed new leases.
The vacancy rate reflects a structural shift rather than a cyclical downturn. Companies that adopted remote or hybrid work policies during the pandemic have largely maintained them, and the office space they once occupied has not been reabsorbed by new tenants. Newer, Class A office buildings with modern amenities continue to attract demand, but older buildings — particularly those without significant recent renovations — are competing for a shrinking pool of tenants willing to sign long-term leases in spaces that may not meet current standards for ventilation, technology infrastructure, or floor plate flexibility.
For building owners facing years of vacancy with no clear path to re-tenanting, conversion to residential use offers an alternative to indefinite carrying costs on an empty asset. The math is not straightforward: office-to-residential conversions require expensive structural work, new plumbing, kitchens and bathrooms in every unit, updated mechanical systems, and floor plans redesigned for residential layouts that look nothing like open-plan office configurations. The Bellwether’s $64.2 million price tag reflects that complexity. But for a building that would otherwise sit vacant and generate no revenue, the conversion represents a path to productive use that does not depend on the office market recovering to pre-pandemic levels.
The Bellwether’s Unit Mix and Pricing Position It as a Mid-Market Loop Option
The Bellwether’s 117 units range from studios to two-bedrooms, measuring 425 to 1,178 square feet. Market-rate rents run from $1,996 per month for smaller studios to $4,887 for larger two-bedroom units with premium finishes. The 41 affordable units are priced below market rate in accordance with the Affordable Requirements Ordinance, though specific affordable rents have not been publicly detailed.
The pricing positions The Bellwether in the middle tier of Loop residential options. It is not competing directly with the luxury high-rises along the lakefront or the newest construction in the South Loop and West Loop, where rents for comparable units can exceed $5,000. Instead, The Bellwether offers a value proposition built on the character of a historic building, a central Loop location at Clark and Monroe with access to multiple CTA lines, and the practical appeal of modern apartment finishes inside a structure with architectural details that new construction cannot replicate.
The 57% pre-leasing rate at grand opening suggests the market is responding to that positioning. First move-ins began in late August, and RMK Management Corp. is continuing to lease the remaining units. The leasing velocity will be an important data point for the five remaining LaSalle Street corridor projects, all of which are in various stages of planning and development. If The Bellwether fills quickly, it strengthens the case for the next wave of conversions. If leasing stalls, it raises questions about whether demand for Loop living at these price points can absorb more than 1,000 new units across six buildings.
What The Bellwether Means for the Future of Downtown Chicago
Gary Stoltz, a partner at R2 Companies, described The Bellwether as more than the transformation of a single building, stating that it demonstrates what is possible when Chicago looks at its historic downtown assets with fresh eyes and invests in their next chapter. That framing is accurate as far as it goes, but the real test is whether The Bellwether remains a milestone or becomes a model.
The five remaining LaSalle Street corridor projects will determine whether office-to-residential conversion is a scalable strategy for downtown Chicago or a limited tool that works in specific buildings with the right combination of structural conditions, TIF availability, and developer appetite for complexity. Each conversion presents different engineering challenges depending on the building’s age, floor plate configuration, ceiling heights, and mechanical systems. What worked at 79 W. Monroe will not necessarily work at every aging office tower on LaSalle Street.
For the Loop as a neighborhood, however, the direction is clear. The pandemic did not kill downtown Chicago, but it ended the version of downtown that existed before 2020. What replaces it will be determined by projects like The Bellwether: buildings that bring permanent residents into a district that was built for daytime office workers, creating demand for the grocery stores, restaurants, schools, and daily services that make a neighborhood function around the clock rather than only from 9 to 5.
