New York City's Mandatory Inclusionary Housing (MIH) program recently inspired a back-and-forth debate in the pages of City Limits.

Sandy Hornick and Lynn Ellsworth both write articles on the subject of New York City's Mandatory Inclusionary Housing (MIH) program, adopted by the New York City Council in 2016 and championed by Mayor Bill de Blasio as a component of the Housing New York Plan.

Ellsworth writes first, describing the MIH program as a failure for falling short of its lofty targets of affordable housing creation. Among a list of failures, Ellsworth includes: "The MIH policy doesn’t work. As of December 2019, only 2,000 'affordable' units of the promised 80,000 have actually been built under the policy. Surely that is a sign of failure." Instead of building affordable housing, argues Ellsworth, MIH "[floods] upzoned neighborhoods with luxury housing, mostly in the form of towers, creating a kind of gentrification on steroids that displaces existing residents and the small businesses that served them."

Ellsworth proposes six policy alternatives to MIH, including incentives for accessory dwelling units, community housing trusts, building on city-owned land, and single room occupancy buildings, among other prescriptions.

Hornick follows with a rejoinder, immediately taking exception to the fundamental issue of how many affordable housing units have been delivered by the MIH program.

Ms. Ellsworth asserts that the city promised that the MIH program would deliver 80,000 affordable apartments but only delivered 2,000. No such promise was ever made. The promise of 80,000 new affordable dwellings was made in 2014 but relates to the total new construction anticipated over 10 years in the Mayor’s Housing New York Plan from all of the city’s programs. At the end of fiscal year 2020—seven years into the program—the city had financed just over 50,000 new units. That’s a little off the pace needed to get to 80,000 newly-built homes in 10 years but comfortably within reach of exceeding 70,000. Falling short of the goal by 10 percent or so may not be a point to brag about but adding over 7,000 new affordable apartments a year is a pretty remarkable accomplishment.

According to Hornick, it's not market-rate housing development that causes gentrification and rising housing costs, as suggested by Ellsworth, but its lack. "In New York City—for at least the past four decades—the shortfall in housing production has resulted in a market pushing up the price of existing housing to the substantial detriment of the less affluent."

As noted by Hornick, the MIH program is only applicable in neighborhoods that have been rezoned since the implementation MIH, which until recently hadn't included any of the more affluent neighborhoods in New York City. The ongoing process of rezoning NoHo and SoHo in Manhattan, along with Gowanus in Brooklyn, will change that dynamic.
