Have you ever wondered why the passenger elevator in a condo shows floor 12 A instead of floor 13?

If you observe the elevators in many condominiums or hotels, you will find that after the 12th floor, it is often not followed by the 13th floor but changed to 12A, 14, or other names instead, causing many people to wonder why there is no 13th floor in condos.

In reality, that floor still exists in the building structure; it is just renamed to avoid the belief associated with the number 13, which is considered an unlucky number in many cultures. 

The origin of the belief about the 13th floor comes from Western culture, which links the number 13 with many unfortunate events in religion, mythology, and traditional beliefs, leading to the term Triskaidekaphobia, or fear of the number 13.

When this belief affects people's feelings, real estate and hotel businesses begin to adapt because, although it is just a number, it does influence customers' decisions. Many projects therefore choose to avoid using the number 13 on elevator buttons to make residents feel more comfortable.

From a marketing perspective, this reduces the Psychological Barrier that might cause some people to hesitate in purchasing or staying, even though the building itself has no actual problems.

In summary, the reason many condominiums do not have a 13th floor is not due to engineering limitations but because of consumer beliefs and psychology, which directly affect the real estate business. This leads many projects to use names like 12A instead to create greater peace of mind for residents.

Although nowadays many people see numbers as just symbols, in many cultures around the world, numbers greatly affect people's feelings and beliefs, especially the number 13, which is considered an unlucky number in many countries, impacting hotels, tall buildings, and condo elevators today.

The belief about the 13th floor does not arise from just one cause but is an accumulation of religious beliefs, legends, and cultures passed down for a long time.

Beliefs from Western culture

One of the main origins comes from the Western world, which views the number 12 as complete, such as 12 months, 12 zodiac signs, or 12 saints. When the number 13 is added, it is seen as an excess number and is associated with incompleteness or bad events.

Religious beliefs and legends

In Christianity, the number 13 is linked to the Last Supper, where there were 13 people at the table before an important event occurred.

Additionally, there are many legends and stories in Europe that associate the number 13 with bad luck and concern.

Influence on hotel and real estate businesses

When this belief is embedded in society, businesses related to accommodation, such as hotels and condos, begin to avoid using the number 13 so that guests or buyers do not feel uncomfortable. In many countries, you will find that there is no 13th floor in condos or no room number 13, even though the actual structure still exists.

Consumer psychology

Although some people do not directly believe in superstition, when the belief spreads in society, it can affect feelings unconsciously.

From a real estate perspective, something as small as a floor number can influence purchasing decisions, room selection, or even confidence in living there.

From belief to a standard used by many buildings

As many buildings begin to avoid the number 13, people become more accustomed to this idea until it becomes normal for many not to be surprised when they see floor 12A in elevators instead of floor 13.

In summary, the belief about the 13th floor has roots in culture, religion, and social psychology, which affects the design and marketing of real estate today. Although the number does not change the actual building structure, it clearly influences people's feelings and decisions.

Once it is understood that the belief about the number 13 truly affects people, the next question is why many buildings choose to use the name 12A instead of directly skipping to the 14th floor.

In reality, renaming floors in condo elevators is not just a matter of superstition but also involves psychology, marketing, and the residents' experience.

The main reasons many projects choose to use 12A are as follows

• Reducing residents' anxiety

• Making customers feel more comfortable

• Helping to sell or rent more easily

• Maintaining the building's floor sequence continuously

• A psychological marketing strategy

• In line with building standards in many countries

• Reducing the stigma associated with unlucky numbers

Although the name on the elevator button changes, in reality, that floor still exists in the building structure; it is just renamed to better suit the residents' feelings.

In summary, using 12A instead of 13 is a combination of belief and business strategy that helps create peace of mind for residents and reduces psychological impacts that may affect decisions to buy or rent real estate.

Although many people see that condo elevators do not have a button for the 13th floor, in reality, that floor has not disappeared because the building structure is still constructed according to the original number of floors, only the name on the elevator button or building plan has been changed.

A common example is that after the 12th floor, it changes to 12A, or some buildings may skip directly to the 14th floor. However, if you count the actual position of the floor in the building, that floor is still the 13th floor according to the engineering structure.

The reason for changing the name instead of actually removing the floor is because high-rise buildings are designed according to the structural system and the number of floors specified from the beginning. Actually removing a floor would affect the entire building design, elevator system, and space layout, which is hardly done in practice.

Therefore, the only thing that changes is the "visible number" to align with the belief about the 13th floor and help reduce residents' anxiety.

In some cases, even though residents know that 12A is actually the 13th floor, the name change still helps psychologically because it makes them feel they are not on a floor with a directly negative image. This is why many buildings choose to rename floors rather than change the actual building structure.

Although in the Western world there is a belief about the 13th floor, in Asia there are also forbidden numbers that many people avoid, especially in real estate, hotels, and high-rise buildings

because in many cultures, numbers are not just symbols but are also directly linked to luck, wealth, and the feelings of the residents

Examples of numbers often avoided in Asia include

• the number 4 in China, which sounds similar to the word "death," so it is considered unlucky

• the numbers 14 and 24, which in some beliefs are associated with negative meanings

• the number 8 is a lucky number linked to wealth and fortune, thus very popular

• room numbers affect purchasing decisions; some buyers are willing to pay more for room or floor numbers considered lucky

• real estate uses numbers as a marketing strategy; many projects choose floor or room numbers to align with the beliefs of their customer groups

from the perspective of the real estate market, numbers are not just personal beliefs but have become one of the factors that directly affect feelings, purchasing decisions, and the project's image

in summary, it is not only the 13th floor of condos that is avoided, but many Asian countries also have beliefs about numbers, reflecting that cultural beliefs still influence building design and consumer behavior today

Although many people consider numbers to be merely a personal belief, in reality, the real estate market places significant importance on this matter because the feelings of buyers directly affect their decision to purchase or rent

. Especially in mid-range to premium condominiums, room numbers, floor numbers, or even the absence of a 13th floor can truly influence the perception of value and market demand

. In some projects, rooms with beautiful or auspicious numbers may sell faster than regular rooms, while rooms with numbers that some consider unlucky may take longer to sell, even if the location and room size are similar

. A common example is the number 8, which is popular among Chinese customers because it is associated with wealth and good fortune, resulting in rooms with this number often receiving special attention

. Conversely, numbers with negative connotations, such as 4 in some Asian cultures or 13 in the West, may cause some buyers to hesitate, even though these numbers do not affect the actual quality of the property

. For developers, these issues become part of marketing strategies because designing floor or room numbers in line with beliefs can help increase customer comfort and reduce concerns

. From an investor's perspective, understanding this is also beneficial as it may affect the ease of renting, reselling, and the target customer group in the future

. In summary, beliefs about numbers influence condominium prices and purchasing decisions to some extent, especially psychologically and emotionally for consumers. Although not the most critical factor, it is a detail that the real estate market values more than many people think

Looking at the overall picture, it can be seen that the absence of a 13th floor button in condo elevators is not a coincidence but results from a combination of beliefs, culture, and consumer psychology that directly affect the real estate business.

Although in reality, that floor still exists in the building structure, many projects choose to rename it as 12A or use other methods to avoid negative perceptions related to the belief about the 13th floor and to help residents feel more comfortable.

A small matter like a number thus becomes a detail that affects building design, marketing, and people's purchasing decisions in the real estate world, reflecting that consumers' emotions and feelings remain as important factors as location or price.
