English basement

English basements are sometimes rented out separately from the main dwelling, either by a single landlord who owns both portions of the building or by a tenant of the building who sub-lets the English basement. English basements are most common in larger, older cities like London, Edinburgh, New York City, Boston, and Washington, D.C.^[2]

In other cities, such as Chicago and San Francisco, this space is referred to as a "garden apartment".^{[citation needed]} The phrase "English basement" is mostly an Americanism. In Québec, in both English and French, this space is known as a "demi sous-sol," literally a "half-basement." In the United Kingdom, this style of apartment is usually known as a "garden flat" so long as it connects to a rear garden; the level of the property is referred to as "lower ground". The origin of the term "English basement" dates back to at least the mid-19th century. The earliest citation in the OED is 1853 ("1853 N.Y. Daily Times 8 July 5/3 (advt.) House for sale... A new three-story English basement house."). Some people refer to it as the "garden level". Building codes in most cities use neither of the phrases, stating that any floor partly below grade-level is simply a "basement" and a floor more than 50% below grade-level is a "cellar".^{[citation needed]}
