Check out these zoning restrictions of a hotel-condo built in a manufacturing district in NYC

From "Trump Condos Come With Restrictions," in AM New York:

With an outdoor pool on the fifth floor, fine dining at street level and a private library in the lobby, the 42-story Trump SoHo won't only be the tallest building in the neighborhood, it will also be the most luxurious. Yet no matter how many millions they pay for the 400 condos that will soon be available for purchase, the new owners will not be permitted to hang even a single family photograph on the wall.

Nor will they be allowed to live in their condos for more than 29 consecutive days or more than 120 days in any year. The rest of the time the condo must be rented out as a hotel room. These rules are specified in a "restrictive declaration" from the city's Department of Buildings, which the developers had to sign before construction of the Trump SoHo was approved last May. The area is zoned for manufacturing, and hotels are the only kind of residential buildings allowed...

Even the wealthiest of owners will not be able to just "spend their way out of a fine" and live there year-round, said Schwarz, because the city can bring a lien on any condo whose owner is not complying with the restrictive declaration. If the buildings department believes that Trump SoHo management is lying about occupancy, it can order the building to hire a private investigator to conduct a full audit.
