A New Federal Law Was Supposed to Slow Institutional Housing Money Down. For Build-to-Rent Construction, It may Do the Opposite
Chicago's build-to-rent supply grew 76 percent between 2017 and 2022, making the region one of the top 20 metro markets in the country for the category. Illinois now has 193 build-to-rent units planned or under construction per million residents, and Chicago ranks in the top 30 metros nationally for units currently under construction. This is not a fringe housing type anymore. It is a real, growing construction category in the suburbs.
Then 2026 got complicated. Nationally, single-family built-for-rent starts fell to roughly 14,000 in the first quarter, down from 19,000 a year earlier, as financing costs rose and a new federal law aimed at institutional housing investors moved through Congress. That law passed in July, and the way it was written may end up pushing more institutional capital toward exactly the kind of ground-up construction happening in Chicago's suburbs right now.
Build-to-rent communities are newly constructed single-family homes or townhomes built specifically for rental occupancy, not scattered individual houses an investor bought one at a time. They are professionally managed as a single community, usually with shared amenities like a pool, fitness center, or event lawn, and they give renters the yard, garage, and space of a house without the ones-above-and-below-you noise of an apartment building. That distinction matters for the new law discussed below.
Several named projects show what this looks like on the ground. Terrabrook at Prairie Ridge in Hampshire is D.R. Horton Chicago's first townhome rental community, professionally managed by Greystar, with 1,828 square foot open concept units and base rents starting around $2,500 a month. Redwood Living is nearing completion on Redwood Aurora, a 140-unit build-to-rent community offering eight single-story floor plans between 1,294 and 1,709 square feet, each with two bedrooms, two bathrooms, and a two-car garage. In Oswego, Home at Ashcroft is a 178-unit build-to-rent community built around three-bedroom homes.
Not every proposal makes it through. Core Spaces, a developer better known for student housing, has built a build-to-rent brand called Oxenfree, and proposed 140 rental homes, 112 single-family units and 28 townhomes, on the former Scott Foresman office campus in Glenview. The roughly $85 million project would have packed about 7.25 homes per acre, more than three times the density of the neighboring Tall Trees subdivision. Residents pushed back hard, and Glenview's commissioners denied the proposal. That fight is a useful reminder that build-to-rent zoning approvals are not automatic in Chicago's suburbs, and density is usually where the argument happens.
In January 2026, the president signed an executive order stating that large institutional investors should not be buying single-family homes that families could otherwise purchase. Congress followed with the 21st Century ROAD to Housing Act, signed into law in July 2026. The law bars any large institutional investor, defined as a for-profit entity controlling 350 or more single-family homes, from purchasing additional existing single-family homes.
Here is the detail that matters most for construction: the law carves out an explicit exception for build-to-rent properties. Institutional investors are locked out of buying existing houses, but they are not locked out of building new rental communities from the ground up.
Before this law, institutional capital chasing single-family rental exposure had two paths: buy existing homes one at a time, or fund new build-to-rent construction. The new law closes the first path and leaves the second one wide open. That does not guarantee a wave of new capital flooding into ground-up construction, financing costs are still a real headwind, and Q1 2026 starts already show the sector cooling. But it does mean the institutional money that still wants single-family rental exposure now has one legal route left, and that route runs directly through new construction in places like Hampshire, Aurora, and Oswego.
For anyone building suburban rental housing right now, that is worth watching closely over the next year or two as the market absorbs what the new rules actually mean.
A build-to-rent community is not a scaled-down apartment complex. These projects build horizontally instead of vertically, which means more land, longer utility runs, and a site plan built around private garages and yards rather than a shared parking structure. Amenity packages tend to mirror what Christopher Todd Communities and similar operators have proven out nationally: a pool, a fitness center, an event lawn, and shared green space, built to a resort standard even though every unit is a standalone home or duplex.
Delivery is usually phased too. A builder rarely completes all 140 or 178 units at once. Homes come online in groups as leasing absorbs the earlier phases, which means a contractor on one of these projects is managing an active construction site and an occupied, leased community side by side for much of the build.
Developers pursuing build-to-rent in the suburbs should expect the Glenview pattern to repeat. Density is where these fights get won or lost, and a project that pencils out financially at 7 homes per acre may not survive a planning commission vote next to a subdivision built at a fraction of that density. Building the zoning and community engagement timeline into the schedule from the start matters as much as the construction plan itself.
For municipalities, the calculation is different. Build-to-rent brings new housing stock and tax base without requiring for-sale inventory, but it also brings density questions that existing neighbors will raise loudly, as Glenview showed. Communities that get ahead of that conversation with clear build-to-rent zoning standards tend to see fewer contentious hearings than ones handling each proposal case by case.
Build-to-rent construction in Chicago's suburbs is not going away. The market cooled in early 2026, but the new federal law leaves ground-up construction as the one clear path left for institutional capital that wants single-family rental exposure. Expect more projects like Terrabrook at Prairie Ridge and Redwood Aurora, more zoning fights like Glenview, and a suburban housing market where build-to-rent keeps carving out real market share alongside traditional multifamily and for-sale housing.
Build-to-rent construction means horizontal site planning, phased delivery around active leasing, and resort-style amenities built to a standard renters expect from a house, not an apartment.
