The thirteenth floor is a designation of a level of a multi-level building that is often omitted in countries where the number 13 is considered unlucky. [1] [2] Omitting the 13th floor may take a variety of forms; the most common include denoting what would otherwise be considered the thirteenth floor as level 14, giving the thirteenth floor an alternative designation such as "12A" or "M" (the thirteenth letter of the Latin alphabet), or closing the 13th floor to public occupancy or access (e.g., by designating it as a mechanical floor).
Reasons for omitting a thirteenth floor include triskaidekaphobia on the part of the building's owner or builder, or a desire by the building owner or landlord to prevent problems that may arise with superstitious tenants, occupants, or customers. In 2002, based on an internal review of records, Dilip Rangnekar of Otis Elevators estimated that 85% of the buildings with at least thirteen floors [ clarification needed ] with Otis brand elevators did not have a floor named the 13th floor. [3] Early tall-building designers, fearing a fire on the 13th floor, or fearing tenants' superstitions about the rumor, decided to omit having a 13th floor listed on their elevator numbering. [3] This practice became commonplace, and eventually found its way into American mainstream culture and building design. [3]
Vancouver city planners have banned the practice of skipping 4s and 13s, since it could lead to mistakes by first responders, for example going to the wrong floor. [4]
The origin of skipping the thirteenth floor when installing elevators is not known. However, during the advent of early skyscrapers, New York architectural critics warned developers not to exceed the height of the 13th floor. [5] These critics insisted that buildings rising above the 13th floor (130 feet or 40 metres) would lead to increased street congestion, ominous shadows and lower property values. Nevertheless, in a work published in 1939, sociologist Otto Neurath compared the use of money in an economy, which he saw as unnecessary, to the superstition of not installing the thirteenth floor: merely a social convention.
Most commonly, 13 is skipped, as in: 12, 14, 15... The floor labeled "14" on the elevator is the thirteenth floor and the number 13 is skipped on the elevator console. In such buildings, floors after 12 are nominally incorrect, with their labeled floor being one higher than the actual floor.
Sometimes to keep numbers consistent the 13th floor is simply renumbered as 12A or 12B, as in: 12, 12A, 14.., or 12, 12B, 14; this does not affect the numbers of the higher floors. Likewise, 14 could be used for the 13th floor and 14A or 14B could be used for the 14th floor.
Other buildings will often use names for certain floors to avoid giving a floor on the building the number 13 designation. One such example is the Radisson Hotel in Winnipeg, Manitoba, where the 13th floor is called the pool floor. Another example is the Sheraton on the Falls in Niagara Falls, Ontario, where the 13th floor consists solely of a restaurant. A third example is the Trump International Hotel and Tower Chicago in Chicago, Illinois, where the 13th floor is the mezzanine floor.
Sometimes, the floor is put to some other use, such as a mechanical floor. Such usage is sometimes the subject of conspiracy theories (see below).
In Richmond, Virginia, the Monroe Park Towers has a 13th floor, but it is used for mechanical equipment and is only accessible from the freight elevator or the stairs. The M designation on the elevator buttons of the freight elevator can also be construed as meaning the Mechanical level in this particular building, or as a Mezzanine level.
Sometimes, a tenement block will contain split-level apartments where the units themselves contain internal staircases and the main elevators for the building therefore do not stop on every floor. One example is Princess Towers in Kingston, Ontario, which has 16+1⁄2 stories excluding the roof-top. The elevators stop at B (basement), G (ground), 3, 6, 9, 12 and 15th floors only. In this case, the unmarked 11th and 13th floors are accessed within units on the marked 12th floor.
In a 2007 Gallup poll, [6] 13 percent of American adults reported that they would be bothered if given a hotel room on the thirteenth floor, while 9 percent indicated that they would be sufficiently bothered to request a room on a different floor. Research on thirteenth-floor effects on real estate values presents a mixed picture. Several prominent American real estate developers have claimed that they are unaware of any reduction in the value of thirteenth-floor offices or apartments. [1] On the other hand, in studies conducted in Russia, Antipov and Pokryshevskaya, [7] and Burakov [8] found that thirteenth-floor apartments were less likely to sell compared to apartments on twelfth or fourteenth floors. This effect, however, was eliminated if developers offered buyers a 10% or greater discount on the cost of thirteenth-floor apartments.
Similarly, new buildings in some parts of China avoid the fourth, fourteenth, twenty-fourth, etc. floors, as the word "four" (Hanzi: 四) sounds like "death" (死) – pronounced "sì" and "sǐ", respectively in Mandarin, the predominant language for the country, and most other varieties of Chinese. A small number of buildings also follow the American tradition of omitting the thirteenth floor, with the fifteenth floor immediately following the twelfth. Another variant found in Vietnam is naming floors 13 and 14 as floors "12A" and "12B" respectively.
In South Korea, buildings tend to include the fourth floor in spite of similar pronunciation issues in the Korean language, though some newer buildings may substitute the letter F in the place of the number 4.
In Italy, where 17 is considered unlucky, cruise ships built and operated by MSC Cruises lack a Deck 17. [9]
In some buildings, 13 is also skipped as a room number. The 13-room (as of 1946) Boots Court Motel on U.S. Route 66 is one example; its rooms are numbered 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 14. [10]
Some conspiracy theorists have suggested that the thirteenth floor in government buildings is not really missing, but actually contains top-secret governmental departments, or more generally that it is proof of something sinister or clandestine going on. This implication is often carried over, implicitly or explicitly, into popular culture; for example in:
Triskaidekaphobia is fear or avoidance of the number 13. It is also a reason for the fear of Friday the 13th, called paraskevidekatriaphobia or friggatriskaidekaphobia.
13 (thirteen) is the natural number following 12 and preceding 14.
The Dakota, also known as the Dakota Apartments, is a cooperative apartment building at 1 West 72nd Street on the Upper West Side of Manhattan in New York City, United States. The Dakota was constructed between 1880 and 1884 in the German Renaissance style and was designed by Henry Janeway Hardenbergh for businessman Edward Cabot Clark. The building was one of the first large developments on the Upper West Side and is the oldest remaining luxury apartment building in New York City. The building is a National Historic Landmark and has been designated a city landmark by the New York City Landmarks Preservation Commission. The building is also a contributing property to the Central Park West Historic District.
An apartment, flat, or unit is a self-contained housing unit that occupies part of a building, generally on a single storey. There are many names for these overall buildings. The housing tenure of apartments also varies considerably, from large-scale public housing, to owner occupancy within what is legally a condominium, to tenants renting from a private landlord.
A penthouse is an apartment or unit traditionally on the highest floor of an apartment building, condominium, hotel, or tower. Penthouses are typically differentiated from other apartments by luxury features. The term 'penthouse' originally referred, and sometimes still does refer, to a separate smaller 'house' that was constructed on the roof of an apartment building. Architecturally it refers specifically to a structure on the roof of a building that is set back from its outer walls. These structures do not have to occupy the entire roof deck. Recently, luxury high rise apartment buildings have begun to designate multiple units on the entire top residential floor or multiple higher residential floors including the top floor as penthouse apartments, and outfit them to include ultra-luxury fixtures, finishes, and designs which are different from all other residential floors of the building. These penthouse apartments are not typically set back from the building's outer walls, but are instead flush with the rest of the building and simply differ in size, luxury, and consequently price. High-rise buildings can also have structures known as mechanical penthouses that enclose machinery or equipment such as the drum mechanisms for an elevator.
A mechanical floor, mechanical penthouse, mechanical layer or mechanical level is a story of a high-rise building that is dedicated to mechanical and electronics equipment. "Mechanical" is the most commonly used term, but words such as utility, technical, service, and plant are also used. They are present in all tall buildings, including the world's tallest skyscrapers, with significant structural, mechanical and aesthetics concerns.
The Vüze, formerly known as Fenwick Place and Fenwick Tower, is a residential apartment building in the south end of Halifax, Nova Scotia, Canada. At 106 metres and 33 storeys in height, it was the tallest building in Atlantic Canada from its construction in 1971 until 2023.
Tetraphobia is the practice of avoiding instances of the digit 4. It is a superstition most common in East Asian nations and is associated with death.
Multifamily residential, also known as multidwelling unit (MDU)) is a classification of housing where multiple separate housing units for residential inhabitants are contained within one building or several buildings within one complex. Units can be next to each other (side-by-side units), or stacked on top of each other (top and bottom units). Common forms include apartment building and condominium, where typically the units are owned individually rather than leased from a single building owner. Many intentional communities incorporate multifamily residences, such as in cohousing projects.
The thirteenth floor of a building is often omitted because of superstition.
