A New York City judge has ordered an Upper West Side woman to stop renting out her rent-controlled apartment on Airbnb immediately.

Noelle Penraat, 62, made $61,000 in nine months from renting out three of the four bedrooms in her apartment, according to the judge. Penraat's landlord, Brookford LLC, sued her in October.

"She has been profiteering from a rent-controlled apartment partially subsidized by another government program," wrote the judge, who found that Brookford LLC has grounds to evict her.

Penraat pays about $4,200 per month for the rent-controlled and senior-subsidized apartment she inherited from her father, according to the New York Post, but can bring in as much as $6,500 per month in short-term rental income.

Paying $4,200 a month may not sound like a steal, but for a four-bedroom on Central Park West, it's just a fraction of market rate.

Penraat claimed in court that renting the apartment was not illegal because she is home when guests are there. And in fact, New York law does not regulate against renting out rooms when the homeowner is present — but Penraat is not the homeowner. She also argued that it was not commercial, but the judge struck that down.

“Unlike a typical sleepover, these guests are not staying for free,” the judge wrote.

Brookford LLC has accused Penraat of running a bed and breakfast.

Short-term rentals have become a contentious issue in New York City, where housing prices are sky-high, and Airbnb is at the center of the controversy. The company claims most people who use the service are individuals supplementing their income, but the New York State Attorney General said that a review of thousands of listings found about 72% were illegal.

Airbnb countered by saying that the data the attorney general analyzed is out of date.

Even rentals that are not illegal by law can violate leases. Standard leases in New York do not allow tenants to profit from properties.

The judge said Brookford LLC has grounds to evict Penraat, who has lived at the Central Park West address for 60 years.
