NYC's best shot at affordable housing has hit some roadblocks

Office-to-residential conversions — 1 of New York City's starring housing strategies — person been shaken by caller information concerns.

This summer, a "stop work" bid was issued for the erstwhile Pfizer building successful Midtown owed to structural issues pinch alloy columns, prompting fears of a illness and impermanent removal of the surrounding area. A little Manhattan conversion astatine 222 Broadway was concisely halted complete reports of a cracked horizontal actual beam, and a Midtown East conversion — 750 Third Avenue — was partially stopped, besides because of problems pinch alloy columns.

Mayor Zohran Mamdani plans to build 200,000 caller homes during his first term. The issues pinch the agency conversions raise questions astir 1 of NYC's main intends of boosting lodging supply. Business Insider said pinch argumentation analysts and developers astir the information concerns, building challenges, and what it each intends for the future.

Office conversions require costly retrofitting

When constructing dense housing, cities person a fewer options: They tin build from scratch, build supra existing businesses, aliases person underused hotels and offices into apartments.

Offices, successful particular, are ripe for lodging because galore were afloat aliases partially vacated astatine the height of the pandemic. The NYC agency vacancy complaint was 15.2% successful the 2nd 4th of 2024, the authorities comptroller reported, up from 7.8% successful the 2nd 4th of 2016.

Former workspaces supply a batch of space, but developers and argumentation analysts said building tin beryllium challenging — portion of the logic conversions person faced structural information issues.

Offices typically person a different instauration setup than residential buildings. Emma Waters, a elder lodging argumentation expert astatine the Bipartisan Policy Center, said this makes it much difficult to adjust level plans, adhd floors, and divided into units pinch their ain kitchens and bathrooms.

Plumbing is simply a concern. In a edifice conversion, for example, the abstraction is already equipped pinch the piping and h2o strategy needed to prolong hundreds of toilets and showers. Offices mightiness only person 1 aliases 2 bath setups per floor, which building crews request to supplement during the conversion process.

Most offices besides person ample sets of windows on the exterior, without a cardinal courtyard aliases interior windows. Ensuring each flat has capable sunlight — thing that is some bully for residents and required by galore building codes — tin beryllium a logistical challenge. And residential windows must unfastened for occurrence safety, a characteristic not built into astir agency windows. Updating each of that infrastructure takes important clip and resources.

"In hotels, each room has earthy light," NYC spot developer David Schwartz antecedently told Business Insider. "That's the biggest problem. That's why the agency conversions are overmuch much difficult — because erstwhile you commencement cutting retired actual successful the mediate of a building, you've put yourself into a really analyzable project."

Waters added that conversions are easier successful smaller buildings. "It is very, very task limited connected whether it's going to beryllium faster and much cost-effective than building a caller building, aliases if it's going to beryllium ace analyzable and require a batch of costly retrofits," she said. She added that co-living models — for illustration having individual chamber spaces but central, shared kitchens and bathrooms among neighbors — could beryllium a happy medium.

Conversions stay important for lodging supply

Despite elevated information concerns, agency conversions stay 1 of New York's apical lodging priorities. Manhattan converted 5 cardinal quadrate feet of agency abstraction successful 2024, up from 2.7 cardinal the twelvemonth prior. Aside from a dip during the pandemic, conversions for illustration this person been trending upward.

There are besides existing taxation and subsidy programs that incentivize office-to-housing projects. The authorities rolled backmost a 60-year-old restrictive zoning rule this year, making it easier to build denser flat buildings. The Mamdani management has taken circumstantial actions to streamline permitting and construction, and the newest national lodging measure includes grants to thief cities for illustration NYC offset the costs of converting commercialized abstraction into homes.

All owners and developers for the Manhattan agency projects flagged for information issues person made nationalist statements that they are reviewing information archiving and protocols for the buildings and making repairs. The developers did not respond pinch circumstantial comments to Business Insider. At a July property convention astir the compromised Midtown building, Mamdani said, "Safety is paramount for america successful each determination we are making correct now."

Meanwhile, market-rate rents successful New York City proceed to climb, reaching $5,000 a month successful Manhattan this summertime arsenic proviso dwindles. The mostly of residents are rent-burdened, meaning they walk astatine slightest 30% of their full income connected housing.

Structural issues whitethorn slow down a fewer circumstantial projects, but Waters said agency conversions are present to stay. If Mamdani plans to build 200,000 caller homes — and make rent much affordable successful the agelong tally — each caller building pinch a fewer 100 units counts toward that goal.

"It's decidedly an each of the above, arsenic needed situation," Waters said. "We are really, really heavy into this proviso deficit. There's not going to beryllium a metallic bullet."
