Here's how to know if your ground-floor apartment is legal or not

While many New York City apartment listings will use the term "basement" or "cellar" interchangeably to describe a space, there are real differences between the two, points out Brownstoner in a recent story

For starters, cellars are not inhabitable, according to NYC rules, and a basement must have at least half of its height above curb level; also remember that for a bedroom to be legal, it must have a window, and a ceiling must be at least seven feet tall.

But don't worry, if you're living in a classic, garden-floor brownstone apartment, chances are your place passes muster. "As there are only typically a few steps down to that floor, 50 percent of the floor-to-ceiling height is usually above grade, and thus meets the requirements of being a basement," reports Brownstoner. "There is also likely a cellar below with building mechanicals."

Less than ideal: "a low-stoop house (such as a limestone and typical circa-1900 two-families)," where "legality may be more ambiguous. The under-stoop floor may be the lowest level of the house, and may contain the building mechanicals."

Signs of trouble include a lack of windows, small windows, or really low ceilings, according to the Department of Buildings website.
