Can LaSalle Conversions Really Fix Housing?

Will office to apartment conversions help Chicago's housing shortage? Our short answer: they will help the Loop substantially and the city only modestly. The LaSalle Street pipeline is on track to deliver more than 1,765 units, several hundred of them income-restricted, which transforms a struggling corridor but covers only a small fraction of a shortfall that advocates and analysts commonly size near 100,000 affordable homes. This piece walks through the promise, the math, and what we think it means for downtown owners as of June 2026.

The promise: what LaSalle Reimagined actually delivers

The LaSalle Street Reimagined initiative now represents roughly $900 million of investment across six conversion projects, expected to produce more than 1,765 housing units from about 2 million square feet of mostly vacant office space, with most projects targeted for completion around the end of 2026, according to Construction Dive and Multi-Housing News. By the standards of American downtown-revival programs, that is a serious pipeline, not a press release.

The individual deals show how the program works. At 79 West Monroe, a roughly $64 million conversion is creating 117 apartments, 41 of them affordable. At 30 North LaSalle, city officials approved partial funding in January 2026 for a much larger conversion of 349 units, 105 of them affordable, per Chicago YIMBY. The pattern across the subsidized projects is consistent: roughly 30 percent of units set aside as income-restricted housing in exchange for public support. We covered the construction status of the corridor in our earlier report on LaSalle Street conversion progress; this piece is about whether the strategy adds up.

How many units does Chicago actually need

How big is the hole these projects are filling? Honest answer: nobody can give you a single audited number, but every serious estimate dwarfs the LaSalle pipeline. The figure cited most often, around 100,000 homes, comes from housing advocacy and policy analyses of Chicago's affordability gap, and we present it as that, an advocacy and analysis framing rather than a settled government statistic. Different methodologies produce different totals. What the estimates share is scale: tens of thousands of households paying more than they can sustainably afford.

Set 1,765 units against that backdrop and the arithmetic is sobering. Even counting every LaSalle unit, market-rate and affordable alike, the corridor delivers somewhere around 2 percent of the commonly cited shortfall. The affordable share, plausibly 500 to 600 units across the pipeline, is a smaller slice still. Some boosters have described the program as increasing the Loop's affordable housing stock by something like 1,000 percent, and while we have seen that framing repeated, it says more about how little affordable housing the Loop had before, which was close to none, than about the citywide gap. The deeper structural problem, as we argued in our piece on Chicago's missing middle housing shortage, sits in the neighborhoods, where two-flats and small apartment buildings have been disappearing for decades.

Why conversions are expensive and subsidy-dependent

Why do office conversions cost so much? Because office towers were never meant to be homes. Deep floor plates leave interior space far from any window, plumbing has to be run to every unit in buildings designed for a few restroom cores, and century-old facades come with preservation obligations. Industry reporting commonly puts conversion costs around $150 to $300 or more per square foot before acquisition, and the LaSalle deals, with their landmark buildings and affordability requirements, tend toward the expensive end.

That cost structure is why nearly every project in the pipeline leans on public money. City support for the LaSalle program, largely through tax increment financing, has been reported in the range of roughly $250 to $300 million across the projects, a figure we treat as approximate since commitments have shifted as deals evolved. The evidence suggests the subsidy is doing real work: the projects that have moved fastest are the ones where public financing closed first, and the market-rate-only conversion attempts downtown have been fewer and slower. Whether that is a wise use of TIF money depends on what you think the alternative is. We think the honest comparison is not "subsidy versus free conversions" but "subsidy versus a half-empty financial district dragging down the tax base."

What Pew found about doing this cheaper

Is there a more efficient version of this strategy? Possibly. A March 2026 analysis from The Pew Charitable Trusts found that converting obsolete offices into small co-living apartments, dorm-style units with shared kitchens, could deliver roughly 3.9 times more affordable homes per subsidy dollar than conventional conversions. The logic is straightforward: smaller units mean more homes per floor, and shared facilities cut the plumbing problem that drives conversion costs.

Chicago's current pipeline is conventional, full apartments at conventional sizes. We think the Pew finding deserves attention in the next round of deals, because if the city is going to keep writing nine-figure subsidy checks, the cost per affordable home is the number that should govern. A program that produced nearly four times the affordable units for the same public money would be much harder to dismiss as a rounding error against the citywide shortage.

Our take: a meaningful dent, not a cure

So can LaSalle conversions really fix housing? No, and we think it is a mistake to grade them against that standard. What the evidence suggests they can do is fix LaSalle Street: replace vacancy with residents, restore foot traffic and retail viability, protect the property tax base, and seed a downtown population that did not exist before. Several hundred affordable units in a high-opportunity, transit-rich location is genuinely valuable even if it is small against the citywide need. The shortage itself will be solved, if it is solved, in the neighborhoods, through zoning, missing-middle construction, and the kind of affordability dynamics we explored in Chicago's affordability standoff between buyers and sellers.

For downtown owners, the practical read is mostly positive. If you own a Loop or near-Loop condo, roughly 1,800 new households arriving by 2027 supports retail, transit, and the case for downtown living, though new rental supply can pressure rents on individually owned units in the short run. If you own commercial or mixed-use property near the corridor, a stabilizing LaSalle Street is better collateral than a dying one. The history of megaprojects says proximity benefits are real but uneven, a pattern we documented in our review of whether Chicago megaprojects help nearby homeowners. As of June 2026, with most conversions racing toward year-end completion, we would rather own property near this experiment than bet against it.

One more thing worth watching: execution risk. Conversion budgets have a habit of growing once demolition opens up walls in 100-year-old towers, and a stalled project on LaSalle Street would be more visible, and more damaging to confidence, than a stalled project almost anywhere else in the city. The evidence so far suggests the current six are adequately capitalized, but we would treat any new subsidy requests in late 2026 as the early signal of whether this model scales or stalls.
